The present invention relates to the field of electronics and, more particularly, to electronic building blocks and toy building sets.
Currently, people spend many hours a day with technological devices, but most don't know how they work, or how to make their own. For all the interactivity of these devices, people are bound to passive consumption. Furthermore, playing, creating, or integrating electronics into projects, toys and products is intimidating, time consuming, requires an expert skill set, as well as specialized hardware/software platforms. People are afraid to connect electronic objects the wrong way, or to electrocute themselves. This makes building objects with lights, sounds, buttons and other electronic components very difficult and prohibitive to kids, young students, designers, non-engineers, and others lacking necessary experience. But as advances in the miniaturization of technology increase, electronics need to become more accessible to non-experts in a cost effective manner.
It becomes therefore clear that there is an opportunity and need to create a simple, easy to use, accessible electronic building block platform that can still enable the creation of complex, interdependent systems. Such a platform would enhance learning, enable 21st century experimentation and promote innovation. Also, what is needed is a system that acts like an additional material in the creative process and allows children and adults to combine and incorporate the system or its parts with other traditional materials such as paper, cardboard and screws.

In some exemplary aspects, an electronic educational toy or building system is provided that teaches the logic of programming and circuit building without requiring expertise in either. The modular block building system consists of pre-assembled printed circuit boards (PCB) interconnected by small magnets. Each block performs one or more discrete functions (e.g., an LED, a pushbutton, a light sensor with a threshold, etc.), and the blocks can be combined to create larger circuits. Some blocks respond to external events such as mechanical forces, touch, proximity, radio frequency signals, environmental conditions, etc. Other blocks are pre-programmed such as synthesizers, oscillators, etc. Still other blocks simply pass current like wire blocks. Yet other blocks provide current such as power blocks/modules.
In some aspects, the system includes modules having many different manners of interaction between the modules. The interaction between modules, not the modules themselves, may form the building blocks of the creative platform. In previous electronic kits the electronic component may be at the center of the manipulation: resistors, capacitors, batteries, etc. By manipulating the modules in those kits, children learn how electricity flows, how to design a circuit, or how to identify components. This knowledge, however, is application specific and features only a single circuit. It has little or no bearing on how the touch sensitive wheel of an iPod™ works, for example, or how a nightlight works, or how a cell phone vibrates, or how a phone can detect rotation and automatically rotate images on the screen in response to that rotation, or how to make one's own objects that have that interactivity. While we are a society obsessed with increasingly complex electronic devices (such as, for example, DVD players, MP3 players, cell phones, smoke alarms), the current learning tools on the market only teach the very basics of electronics and electricity, such as allowing us to turn on a light or see current flow. There is a widening gap between what is taught to the average American and what is both used and consumed by that American. This is also why most electronic kits and toys are very short-lived in that the kits and toys are not relevant to user's day-to-day life. To date, there is no way for children or adults to be able to create their own interactive objects with custom-designed interactive behavior, without having to program or learn the many complexities involved with advanced electronics. With the present modular system, people will be able to program interactivity intuitively and in a tangible way.
The description and drawings herein are meant as an illustration of one or more exemplary embodiments of the invention, but should not be considered limiting or restrictive. As such, there are a number of manners of modification without departing from the spirit and scope of the invention. In the following text, the words block and module may be used interchangeably to signify the modular circuit boards.
The modules may be divided into categories corresponding to their function. Examples of categories include, but are not limited to: power modules, input modules, output modules, wire modules, etc. Power modules for instance take current from a battery, a wall wart, or other power source, and convert it into current feeding the other components of the system. In any working configuration of modules, there may be at least one power module. Input modules include, but are not limited to: buttons, switches, sensors, logic blocks, etc. Output modules include, but are not limited to: LEDs, displays, sound modules, etc. Wire modules do not perform a particular function, but act as wire extensions, configuration changers, and in some cases logic and state modules.
In one exemplary embodiment, standalone blocks are provided that may enable users, with little or no electronics or programming experience, to construct basic and complex sensor and interaction-based analog and digital circuits.
In another exemplary embodiment, the general electrical operation of the system is as follows. All modules may include a standard interface and communicate automatically when connected. Each module includes three electrical lines and such lines are interconnected between and throughout all modules. These lines include Power, Signal and Ground. At the power modules, Power and Signal lines are at 5 Volts, the system is low power, and the Power and Ground lines are shared among all the modules. In other exemplary embodiments, the power may be something other than 5 Volts such as, for example, 3V, 9V, 12V, 15V, alternating current (AC), etc. Input modules take the incoming control Signal line, and manipulate it according to the module's function, and output the modified Signal voltage. In the case of a pressure sensor connected to a power module, for instance, the sensor module takes 5 Volts into the Signal line, and outputs a voltage between 0 and 5 Volts depending on the amount of pressure applied to the sensor. Output modules respond to the Signal line by “visualizing” the voltage in light, sound, display or other forms.
All modules are pre-assembled, pre-engineered, and contain the logic and circuitry required to make the component readily usable. For instance, an LED module contains a resistor corresponding to its current rating, an Operation Amplifier (OpAmp) as a buffer from the remainder of the circuit, and a coin cell battery module incorporates a discharge protection circuit. In some exemplary embodiments, the system requires no prior knowledge of electronics and does not require any hardware or software platform. In other exemplary embodiments, the system may include a hardware and/or software platform. Also, in some exemplary embodiments, since the modules do not need to be programmed and do not require a central circuit controlling them, the system is standalone and does not need a computer or hub. However, according to one exemplary embodiment, the system may be connected to a device such as a computer, hub, memory storage, or personal electronic mobile device such as a cellular phone, smart phone, etc., in order to create additional functionality or to retrieve information or power from the device.
In some aspects, the modules are designed to couple together and cascade one after the next. The modules include magnetic connectors that ensure electrical connectivity and may be developed and mounted on the PCB. The magnetic connectors may be in male form and female form, and in some examples may correspond to north and south faces of magnets. For standard blocks, each block may have two magnetic connectors mounted on it, one with the north face of the magnet(s) facing out and the other with the south face of the magnet(s) facing out. The south facing side of the magnetic connector of one module connects to the north facing side of the magnetic connector on the next module. This ensures proper connection and appropriate polarity. The repelling polarities inhibit the magnets from connecting in an inappropriate manner to facilitate connecting of the modules in the correct manner.
In another exemplary embodiment, the magnetic connector includes two magnets and three conductors embedded in an injection molded plastic body. The two magnets act as polarizing and locking elements, whereas the conductors carry the signal from one circuit board to the next through the mating of the male and female connectors. In the male version of the connector, the three conductors are spring probes. On the female version of the connector, the conductors may either be spring probes or small metal plates. Either way, the spring probes or the metal plates come into contact with the spring probes of the male connector and transfer the electrical signals into the circuit board. The magnetic connector also features an interlocking system as part of the plastic casing in the form of male and female complementary components. In one example, a male protrusion is included on one block and a female indentation is included on a second block. The protrusion and indentation cooperate to inhibit the blocks from sliding with respect to each other. In another example, a male protrusion and a female indentation are included on each block and the male protrusions and the female indentations on interfacing blocks cooperate to inhibit the blocks from sliding with respect to each other.
According to one exemplary embodiment, the magnetic connector also features an interlocking system as part of the plastic casing in order to inhibit the modules from sliding side-to-side with respect to each other, and to ensure that the modules are assembled in the correct orientation (i.e., to inhibit an upside-down connection). To inhibit side-to-side movement, the connectors can include a protrusion on the male or female side that corresponds to an indentation on the corresponding female or male side. Once the modules are connected, the protrusion enters the indentation and the modules are sufficiently locked together such that side-to-side movement is inhibited. In another embodiment, the connectors can include a tabbed feature to inhibit side-to-side movement. For example, as shown in
In addition to the previously described exemplary connectors, many modifications to the connectors are possible, including, but not limited to, the casing, the type of conductors used, the number of conductors, as well as whether or not the magnets are acting as conductors, the number of magnets, the shape of the magnets, the polarity of the magnets, the manner in which the connectors couple to the circuit board of the block, etc.
In order for the system to be expressive and broaden, rather than constrain creativity, the number of available modules needs to be plenty. In general, only having a few nuts and bolts in the prototyping process is not very helpful, and alternatively can even be prohibitive. The present invention allows for the addition of new modules according to the interconnection and voltage standards. For example, starting from a set of a hundred modules, we can imagine and design hundreds or thousands of additional modules that fit and cooperate with the present system to extend the system's functionality. For example, we can potentially build modules such as galvanic skin sensors, arsenic detectors, microcontroller modules, etc., as well as adapter boards to other electronic block building systems and interfaces.
At least one exemplary embodiment has been designed to allow for complex behaviors programmed through physical interaction. The set features logic and state modules that introduce the concept of programming to novices. Examples of such modules are the AND, OR and NOT blocks, as well as the Threshold block. These enable the user to program certain behaviors of his/her designed system without needing to learn a programming language, to write code on a computer, or to program a microcontroller circuit. Programming here is done through using logic modules to create decision trees. Also, modules feature controls such as switches, knobs and buttons that enable selection of modes of behavior. Just like a blender can have three buttons, each button corresponding to a particular speed of its motor, some modules in the present invention allow for the selection of a mode or adjustment of their behavior. For instance, a proximity sensor block can contain a mode switch and a potentiometer. Through the manipulation of the embedded potentiometer, the threshold level can be set, determining the input voltage level beyond which the module should output a high. Also, by flipping the switch, the module can go from normally-high to normally-low, in essence inverting its response to the desired threshold.
All blocks may be designed with space constraints in mind and may be kept at the minimum size possible in order to make the blocks easily integrable with other materials such as, for example, cardboard, plastic, pipe cleaners, etc. The blocks are user friendly in their look as well as their size, and make playing and prototyping with them attractive to children and adults alike regardless of the goal.
The modules may be offered as individual blocks or as sets. These can range from standard block components to specialized sets such as sensor sets, mechanical sets, biological sets, sound sets, etc. Also, users can design and build their own modules or sets to extend the library.
In some aspects, an electrical connector is provided and includes a housing defining a side surface, an electrical conductor supported by the housing and including an engagement portion proximate the side surface of the housing, wherein the engagement portion is adapted to engage another electrical conductor of another electrical connector, a magnet supported by the housing proximate the side surface of the housing, a projection extending from the side surface of the housing, and a receptacle defined in the side surface of the housing.
In other aspects, an electrical module is provided and includes a circuit board and an electrical connector. The electrical connector includes a housing defining a side surface, an electrical conductor supported by the housing and including a coupling portion and an engagement portion, wherein the coupling portion is adapted to engage and electrically communicate with the circuit board, and wherein the engagement portion is proximate the side surface of the housing, a magnet supported by the housing proximate the side surface of the housing, a projection extending from the side surface of the housing, and a receptacle defined in the side surface of the housing.
In further aspects, a system is provided and includes a plurality of electrical modules selectively couplable together to transmit electrical current from one electrical module to another electrical module, each module has at least one functionality associated therewith and includes an electrical connector adapted to couple to an electrical connector of another one of the electrical modules, wherein, with the electrical connectors coupled together, a functionality of at least one of the plurality of electrical modules is dependent upon at least another one of the plurality of electrical modules.
In still other aspects, a system is provided and includes a plurality of electrical modules adapted to be selectively coupled to one another, wherein the plurality of electrical modules include at least a first electrical module and a second electrical module, the first electrical module including a first circuit board, and a first electrical connector including a first housing, a first electrical conductor supported by the first housing and including a first coupling portion and a first engagement portion, wherein the first coupling portion is adapted to engage and electrically communicate with the first circuit board, a first magnet supported by the first housing, a first projection extending from the first housing, and a first receptacle defined in the first housing. The second electrical module includes a second circuit board, and a second electrical connector including a second housing, a second electrical conductor supported by the second housing and including a second coupling portion and a second engagement portion, wherein the second coupling portion is adapted to engage and electrically communicate with the second circuit board, a second magnet supported by the second housing, a second projection extending from the second housing, and a second receptacle defined in the second housing, wherein, with the first electrical module coupled to the second electrical module, the first magnet is magnetically coupled to the second magnet, the first engagement portion engages the second engagement portion, the first projection is at least partially positioned within the second receptacle, and the second projection is at least partially positioned within the first receptacle.
The present invention is capable of various modifications and alternative constructions, some of which are detailed in the drawings below. However, it should be clear that the intention is not to limit the invention to a particular embodiment or form, but rather the present invention should cover changes, additions and modifications as part of its scope. Independent features and independent advantages of the present invention will become apparent to those skilled in the art upon review of the detailed description and drawings.
Before any independent features and embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of the construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. For example, directional terms such as “top”, “bottom”, “above”, “below”, “front”, “back”, etc. are not intended to be limiting and are used for describing the exemplary illustrated embodiments herein.
An exemplary electronic building system 30 is provided. The electronic building system 30 is not only meant for use with pre-designed components and modules 34, but can also allow users to combine those modules 34 with other traditional prototyping and playing items in a design studio or home. Such materials may include, for example, paper, cardboard, wood, glue, pipe cleaners, foam, etc., thereby encouraging individuals to treat electronics like a material in the creative process.
In some exemplary embodiments, the system 30 may include at least four different types of modules 34: power; input; output; and wire; although more types of modules 34 are possible. Power modules 34 provide electricity to the system 30. Input modules 34 interpret data or their surroundings and provide that input to the system 30. Output modules 34 make visual, physical, or audible changes to their surroundings based on input(s) to the system 30. Wire modules 34 route power and communication between the modules 34 in the system 30.
According to one exemplary embodiment, when a first module 34 is connected to a second module 34, the power signal is transferred from the first module 34 to the second module 34. Accordingly, the second module 34 is powered entirely by the first module 34. If a button module 34, sensor module 34, or other module 34 is placed somewhere between a first module 34 and a second module 34, the current may be affected by the action of the button module 34 or sensor module 34. For example, current may not pass (or, alternatively, may continuously pass) from the first module 34 to the second module 34 unless the button on the button module 34 is depressed or the sensor on the sensor module 34 is activated. Similarly, if a sensor module 34 is only partially activated, then only partial current is transferred from the first module 34 to the second module 34.
Many different types of modules 34 are possible in each category, including but not limited to the following: (i) power modules: wall power modules, battery power modules, solar power modules, discharge protection circuits; (ii) input modules: pulse modules, pressure sensor modules, proximity modules, input recording modules, potentiometer modules, button modules, temperature modules, accelerometer modules, memory modules, timer modules; (iii) output modules: motion modules, vibration motor modules, fan modules, RGB LED modules, LED modules, bar graph modules, speaker modules; and (iv) wire modules: wire modules of various lengths, extender modules, splitter modules, and electroluminescent wire modules. Any known type of circuit or electronic component or combination of components may be used to create a module 34 and thus form a portion of a system 30 built using such components.
The modular system 30 described herein is reusable, scalable from small and simple circuits to large and complex circuits, and are sophisticated enough to allow for complex programming of behavior through manipulating tangible objects (using logic and state modules 34). Additionally, just as programmers use software modules and libraries to create bigger and more complex software programs, the modules 34 are transformed into a library of electronic components that can be used to create bigger and more complex components or systems. Indeed, a user can expand the module library almost indefinitely, adding any new component that they wish to use to their module repository.
Users can even create their own modules 34 and add them to the rest of the library. For example, according to one exemplary embodiment, users may be provided with components of a module 34—such as male magnetic connectors 38A and female magnetic connectors 38B that are able to snap onto or otherwise couple to a small circuit board, sensor, or other electronic component such that the connectors 38A/38B transmit current from one module 34 to another—that they can use to create their own inter-connectable modules 34 built from circuit board, sensors, or output mechanisms that they have built or gathered from another source.
According to another exemplary embodiment, a system 30 comprising several modules 34 may be commercialized as a single kit or set. The kit may include one or more different modules 34 (power, input, output, and/or wire), may comprise one or more different types of each module 34, a container in which to store the modules 34, a mounting board or substrate upon which to place or couple modules, may include learning materials, accessories, instructions, or a variety of other components. For example, a kit may comprise a handful of modules 34 that may be connected in an almost unlimited number of combinations to perform numerous different input and output functions (see
One potential aspect of the exemplary kits, systems, and modules may be to extend the concept of the modular platform into more complex components. According to one exemplary embodiment, the system 30 is adapted to give access to sophisticated devices through, for example, simple three-line analog interfaces. Exemplary complex devices may include, but are not limited to, LCD displays, OLED screens, timers, accelerometers, logic gates, and many more. This may be accomplished by pre-engineering all modules 34 and providing “entry points” into the devices. The entry points are, for example, knobs or switches that allow the user to adjust the intensity or frequency of pulsing, flip modes of operation, set thresholds, make decisions, or remember a configuration, among many other operations. These may be considered “entry points” because they are based on similar devices that people know how to use from their everyday lives. The exemplary modular systems described herein may take lessons and iconography from consumer electronics (such as, for example, blenders, DVD players, alarm clocks, game consoles) and apply them to these semi-raw electronic modules 34. In this way, the modular system 30 may treat electronic components like they are electronic devices. This means the learning curve for using and creating with the modular system 30 is very low, and the user's pre-existing knowledge obtained from manipulating their own consumer electronics may be taken advantage of to allow the users to program new objects through interaction.
An exemplary entry point may include an OLED screen module 34 which requires an SD card slot in which users can insert an SD card preloaded with images and video. The OLED screen module 34 may also include a microcontroller on-board which is pre-programmed with firmware to access and display the images. Also integrated in the OLED screen module 34 may be a toggle switch and a knob, where the toggle switch selects between fixed images/video or looping and the knob adjusts the looping speed. In the above example, even though the circuit-board and firmware itself may be complex, the end result will be an easy-to-use OLED screen module 34 with appropriate iconography that may be accessible to children and novice users alike. The exemplary system 30 may allow for and include the pre-engineering and design of numerous other complex modules 34 similar to the OLED screen example.

With reference to
In some exemplary embodiments, each module 34 may include control and protection circuitry to facilitate safe and easy operation of the module 34. Additionally, each module 34 may include an operational amplifier component used in a buffer configuration in order to reduce the amount of overall current consumption on the overall system 30 of coupled modules 34. This assists with facilitating the cascading of multiple modules 34 without significant loss of power, as well as scaling the system 30 as may be desired. In other exemplary embodiments, the system 30 may include a booster module in the overall system of coupled modules 34 in order to boost the current and/or power traveling through the power lines and ensure proper functioning of all the modules 34 in the system 30.
Beyond being able to produce discrete behaviors by cascading modules 34, the electronic building system 30 allows for programming of certain behavior and aesthetic of the modules 34 through controls. In
Yet another example of programming behavior in the electronic building system 30 through controls is shown in
In some exemplary embodiments, the temperature sensor module may incorporate a mode switch 130 that can flip the behavior of the block 34J from ‘normally-low’ to ‘normally-high’. In contrast to the first explained configuration (which was normally-low), a ‘normally-high’ setting would cause the module 34J to output a high reading except when the temperature exceeds the threshold. This means the audio module 34K would be playing recurrently until the room gets warmer, at which point the audio module 34K will cease to output audio. These controls, in addition to pre-programmed blocks, logic blocks and state blocks, will allow the system 30 to enable complex prototypes and circuits with no programming or electronics knowledge.

As indicated above, modules are adapted to have a variety of different types of functionality and include the appropriate connectors, circuit boards, and associated electrical components coupled to the circuit boards to perform the desired functionality. The modules shown in the illustrated exemplary embodiment are for exemplary and demonstrative purposes, and are not intended to be limiting. The exemplary illustrated modules include a wall power module 34W (power), a bar graph module 34X (input), and an LED module 34Y (output).

The first portion 160′ of the housing also defines a pair of magnet apertures 192 (see
Additionally, the first portion 160′ of the housing defines electrical conductor apertures 200 in the side surface 196 thereof for receiving and supporting a portion of the electrical conductors 168 (described in more detail below). In the illustrated exemplary embodiment, the electrical conductor apertures 200 are circular in shape complementary to the shape of a portion of the electrical conductors 168 received therein. Similarly to the magnet apertures 192, the electrical conductor apertures 200 may have any shape and be complementary to the shape of a portion of the electrical conductors 168 received therein.
The first portion 160′ of the housing further defines a plurality of conductor slots 204 (see
Further, the first portion 160′ of the housing includes a pair of projections 224 extending downward from a bottom surface 208 thereof for coupling the connector 152 to the circuit board 156 of the module 34. In the illustrated exemplary embodiment, the projections 224 are cylindrical in shape and may insert into apertures 228 (see
The housing 160 also defines a receptacle 232 in a side surface thereof and includes a projection 236 extending from the side surface and positioned adjacent the receptacle 232. Such a receptacle 232 and projection 236 are included in each connector housing 160 and assist with proper alignment and coupling together of modules 34. The receptacle 232 is shaped complementary to a shape of the projection 236 such that when a projection 236 is received in the receptacle 232 the projection 236 substantially fills the receptacle 232. When coupling two modules 34 together, such as modules 34X and 34Y, the connectors 152 are aligned with the projection 236 on each connector 152 substantially aligned with the receptacle 232 on the other connector 152, and the modules 34X and 34Y are moved together until the magnetic force of the four magnets 164 on the two connectors 152 is sufficient to pull the connectors 152 together, thereby causing the projections 236 to insert into the receptacles 232. Upon connection, the projections 236 and receptacles 232 of the connectors 152 cooperate to inhibit substantial lateral and vertical movement of the modules 34X and 34Y relative to one another.

It should be understood that the structures, features, functionality, and other characteristics of the various exemplary embodiments of the systems disclosed herein and illustrated in
Although embodiments of modules 34 are shown and described as having a connector (e.g., connectors 38 and 152) coupled to one end or two opposite ends or edges of a circuit board (e.g., circuit boards 46 and 156), in other embodiments, a module 34 can include connectors coupled to more than two ends or edges of a circuit board. For example,
As described above in the many examples of modules and systems, numerous modules may be coupled together to achieve various functionalities of the systems. Modules may be coupled in a cascading manner in which the inclusion of one module in the system may affect the functionality of downstream modules in a first manner and inclusion of a different module in the system may affect the function of downstream modules in another manner different than the first manner That is, modules coupled together in a system may have dependencies upon one another to affect functionality thereof and of the entire system. A simple example to demonstrate this concept, but is not intended to be limiting, comprises a system include three modules: A power module, a button module, and an LED module. The button module and the LED module are dependent on the power module, and the LED module is dependent on the button module. To demonstrate the dependency of the button module and the LED module on the power module considering the following: If the power module is not providing any power, then neither the button module nor the LED module can operate in their intended manner. Similarly, to demonstrate the dependency of the LED module on the button module, if the button is not depressed or otherwise activated to close the circuit, the LED module will not be illuminated, and if the button is depressed, the LED module will be illuminated. In other words, cascading modules in a system affect operation and functionality of downstream modules.
