The present disclosure relates generally a mechanical analog of electronics, and more particularly a mechanical analog of electronics with repositionable members that can be configured to build a mechanical version of virtually any electronics circuit.
Electronics is a cornerstone of modern technology, but it is an especially difficult subject to learn and teach beyond the most basic concepts. It is not possible to see or feel electrons as they flow through circuits, so it is abstract and difficult to relate to. Instead, electronics must be understood through mathematical models that frequently require advanced math, limiting the audience to which electronics can be taught.
One powerful way to aid learning electronics is to think of electronic circuits in terms of a physical analog, that is, a physical representation that behaves just like electronics. The purpose of a physical analog is to make electronics more understandable by relating it to tangible, familiar experiences.
Analogs of electronics have been described in the past using fluids (gas or liquid) as the counterpart to electrons. Fluids are an obvious analog because fluid flows through pipes in much the same way as electrons flow through wires. For example, if water is pushed through a pipe that splits into two pipes, some of the water goes through one pipe and some of it goes through the other. The flow and pressure of water in each pipe can be described using the same relationships one would use to calculate current and voltage in a branching electrical circuit.
Unfortunately, fluid analogs (gas or liquid) have a number of major limitations. For one, you cannot see the movement of fluids through a tube. It looks the same whether it is moving or still. Additionally, liquids have viscosity that causes significant resistance when pushed through tubes, while gases are compressible, causing significant capacitance in tubes. Furthermore, when using gases, a great deal of power is lost from hysteresis during compression and expansion. And on a practical level, it would be very difficult to design a liquid-based system that is not messy or a gas-based system that is not leaky.
The present invention describes a system for building reconfigurable, mechanical analogs of electronic circuits—a physical representation that uses reconfigurable mechanical components in place of their electronic equivalents. The invention includes a mechanical analog of a battery, a mechanical resistor, a mechanical capacitor, a mechanical inductor, a mechanical switch, a mechanical transistor, a mechanical diode, a mechanical junction, and an expandable, reconfigurable base to which the parts attach to build mechanical analogs of electronic circuits. Its purpose is to make electronics tangible and easy to understand: The force of voltage can be felt, the flow of current can be seen (and heard), and the behavior of electronic circuits can be understood intuitively, with only basic math. One can also perturb a circuit and see its effect simply by touching it: touch a part to add resistance or push on it to add voltage.

The summary above is not intended to describe each illustrated embodiment or every implementation of the present disclosure. The figures and the detailed description that follow more particularly exemplify these embodiments.
The disclosure can be more completely understood in consideration of the following detailed description of various embodiments of the disclosure, in connection with the accompanying drawings, in which:
The
While embodiments of the disclosure are amenable to various modifications and alternative forms, specifics thereof shown by way of example in the drawings will be described in detail. It should be understood, however, that the intention is not to limit the disclosure to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the subject matter as defined by the claims.
The mechanical analog will be described shortly, but first it is necessary to define units to describe the mechanical equivalent of electrical voltage, current, capacitance, and inductance. The mechanical analog of a Volt is the Spin Volt (SV), that of the amp is the Spin Amp (SA), that of the Ohm is the Spin Ohm (SΩ), that of the Farad is the Spin Farad (SF), and that of the Henry is the Spin Henry (SH). The key link between the mechanical units and the electronic units is that 1 Coulomb of charge is arbitrarily defined to equal 10 m of chain. From that, all the other units can be derived. For instance, one Spin Volt can be derived to equal 0.1 N.
A major challenge of designing a mechanical analog to electronics is a ubiquitous component that is often overlooked: the electrical junction (i.e., a point where one wire branches into two). When a wire carrying electrical current branches from one path into two paths, the current splits. Some fraction of the current goes in one path and the rest of the current goes in the other. That is, I1=I2+I3.
If you try to use a moving chain as an analog to electron flow, how do you physically split the chain as paths branch? Even if you could slice the chain in half as it ran through the junction, the two halves of the chain would move at the same speed after the split as before the split, and I1 would not equal I2+I3.
The present invention solves this problem by use of a differential gear system (an embodiment of which is shown in
The mechanical junction embodied in
The gear ratios of the epicyclic gears constrain the three sprockets to turn with the following relationship: 3ω1=2ω2+Ω3, where ω1 is the angular velocity of the bottom sprocket 101, ω2 is the angular velocity of the middle sprocket 102, and ω3 is the angular velocity of the top sprocket 103. In order to make the speed of chain running along the three sprockets constrained to the desired equation I1=I2+I3, the diameter of the bottom sprocket 101 is three-fold larger than the top sprocket 101, and the diameter of the middle sprocket 102 is two-fold larger than the top sprocket 103.
Mechanical analogs of other electronic components are also included in this invention. An embodiment of a mechanical resistor is shown in
An embodiment of a mechanical capacitor, which also doubles as a spin Volt meter, is shown in
An indicator on top of the mechanical capacitor shows the spin voltage across the capacitor through transparent cover 312. There are two sets of gradations on top of the capacitor: one that shows negative values (308) and one that shows positive values (307). A clockwise force is considered a positive voltage while a counter-clockwise force is considered a negative voltage. When the sprocket assembly is turned clockwise, protrusion 313 pushes against the short indicator hand 304, keeping it pointed at 0 while protrusion 314 pushes against the long indicator hand 305, forcing it to point to the positive voltage being applied to the capacitor. When the sprocket assembly is turned counter-clockwise, the long indicator hand 305 pushes against protrusion 313, keeping it pointed at 0, while protrusion 314 pushes against the short indicator hand 304, forcing it to point to the negative voltage being applied to the capacitor.
An embodiment of a mechanical battery is shown in
To avoid a situation where the mechanical battery releases its energy too quickly (i.e., a mechanical short), a mechanical analog of a circuit breaker is included. If stack 409 begins to turn too quickly in a clockwise direction, a small arm slides out of stack 409 due to centrifugal force and runs into arm 411, normally held back by extension spring 408. Arm 411 pushes pawl 406 into the base of stack 409, causing it to stop immediately.

The symbol for this mechanical transistor is shown in
When the gate 601 is forced to turn and then the force is removed, the gate returns back to its resting position, partly by force of springs 611 pushing against sliders 605 pushing against tower 606, and partly by torsion spring 609 squeezing protrusions 610 and 607 together.
