The present disclosure relates to toilets. More particularly, it relates to smart toilets equipped to assist users in sitting and/or rising from the toilet.
There is a large population of physically disabled, overweight, and/or aging people that have a difficult time getting on and off a toilet. The solutions on the market right now are either a raised toilet seat, which can be very messy and hard to clean, or a motorized seat that lifts a person to the standing position. These are usually large and cumbersome around the toilet and risk dumping a person off the seat before they are on their feet.
Not all people have the same height or body dimensions. However, nearly all toilets come in only a very small variety of heights. This can make it particularly difficult or uncomfortable for those who are among the tallest and shortest, or more specifically those with the longest and shortest legs, to lower down, sit, or rise from the toilet seat. Conventional toilets also lack any way to adjust the height of the feet. Raising the feet can only be accomplished with stools, typically having a fixed height.
The ability to track an individual's health and wellness is currently limited to the lack of available data related to personal health. Many diagnostic tools are based on examination and testing of excreta, but the high cost of frequent doctor's visits and/or scans make these options available only on a very limited and infrequent basis. Thus, they are not widely available to people interested in tracking their own personal wellbeing.
Toilets present a fertile environment for locating a variety of useful sensors to detect, analyze, and track trends for multiple health conditions. Locating sensors in such a location allows for passive observation and tracking on a regular basis of daily visits without the necessity of visiting a medical clinic for collection of samples and data. Monitoring trends over time of health conditions supports continual wellness monitoring and maintenance rather than waiting for symptoms to appear and become severe enough to motivate a person to seek care. At that point, preventative care may be eliminated as an option leaving only more intrusive and potentially less effective curative treatments. An ounce of prevention is worth a pound of cure.

The present disclosure relates to a toilet with a bowl and seat supported by a frame. The frame includes one or more lifting mechanisms adapted to raise and lower the seat and/or bowl. In some embodiments, there may be separate frames for supporting and adjusting the seat and for supporting and adjusting the bowl. Preferably, the lifting mechanism is further adapted to change the angle of the seat.
In a preferred embodiment, the toilet comprises a motorized seat lift that is integral with and internal to the toilet. It also provides customized lifting motions set to individual users' preferences. The disclosed toilet looks and feels like a conventional toilet and can help prevent fall by keeping a person more supported during a lift and help them to their feet at a height appropriate for the individual.
In a preferred embodiment, the adjustable frame allows the toilet to be both shorter and taller than conventional toilets. This makes the toilet more comfortable and easier to use for both tall and short users, including children, without the need for special stools or spacers.
In various exemplary embodiments, the bowl is supported by a frame including at least one actuator. In various exemplary embodiments, the seat is supported a frame comprising at least one actuator. In various exemplary embodiments, the frame comprises two, three, four, or more actuators for the bowl and/or seat. In a more preferred embodiment, the frame comprises three pairs of actuators to move the seat. Preferably, the actuators are controlled by a digital controller that coordinates the actions of the actuators to thereby provide a smooth lifting and lower at the desired speed. More preferably, the controller is programmable, so that users can program the lifting and lowering of the seat to their preference. Even more preferably, the toilet includes a user identification module, so that the user is automatically identified as he or she approaches or sits on the toilet.
Referring to
In various exemplary embodiments, the shroud 400 covers all the internal support components that comprise the frame as well as the bowl 300. In preferred embodiments, the shroud 400 comprises one or more sections of articulated or flexible (e.g. elastic, material) assembled such that the shroud 400 can contract or expand as the frame 110 moves the bowl 300 and/or seat 200. Other sections of the shroud may be rigid. In various exemplary embodiments, the at least some portions of the shroud are removable or openable to allow access to the interior of the toilet frame. The interior of the toilet frame may include, among other things, plumbing connections, fluid supply lines, support structures, health and wellness assessment devices, electronic circuits, digital devices (e.g., processors, memory), storage tanks, and communication modules.
In various exemplary embodiments, the shrouds 400 are preferably designed for aesthetic and other purposes. For example, the shrouds 400 can be made in various colors to suit the décor of the bathroom the toilet is installed in. Besides colors, the shrouds 400 can include patterns or graphics so that the toilet 100 “makes a statement” in the bathroom.
In various exemplary embodiments, the handles 210 include one or more buttons, switches, sensors, etc. through which the user may control the seat, including, but not limited to, starting and stopping the seat 200, reversing seat movement direction, adjusting the position or angle of the seat 200, and adjusting the height of the bowl 300, seat 200, or foot platform 120.
In various exemplary embodiments, the handles 210 may include one or more health and wellness sensors. The sensors may be used to measure how hard the user is gripping and provide feedback to the lift control. For example, if a user suddenly increases their grip it is likely that they are struggling with standing or with their balance. Grip pressure may also be tracked over time. The sensors may also include detection for heart rate, body temperature, hand health indicators, cameras, electrocardiogram, pulse, blood test (e.g., using a finger prick), etc. Toilet handles with health and wellness sensors are disclosed in U.S. Patent Pub. No. 2018/0084959, the entire disclosure of which is incorporated herein by reference in its entirety.

In a preferred embodiment, a pair of first actuators 111 are pivotally connected to a front area of the seat 200 and a pair of second actuators 112 are pivotally connected to a back area of the seat 200 providing support at four “corners” of the seat 200. The four actuators 111 and 112 are also pivotally attached to the frame 110. An additional pair of third actuators 113 are pivotally attached to the frame 110 at one end and pivotally attached to the second pair of seat actuators 112 at their other end. In another embodiment, the third actuators 113 are attached to the first pair of actuations 111.
In various exemplary embodiments, the use of multiple 111, 112, and 113 actuators for the seat 200 control provide the ability to move the seat 200 with much greater control and precision than previous external seat lift systems. By using multiple actuators 111, 112, and 113 with multiple lift points, it is possible to lift and lower in different directions and at different speeds at different points on the seat.
Referring to
In various exemplary embodiments, the toilet 100 also includes a foot platform 120 with a foot lift mechanism. The platform 120 may be used to provide foot support for shorter users or to elevate the user's legs to a more ergonomically optimal position for defecation (i.e., a “squatty potty”). The “squatty potty” position could also be achieved by lowering the bowl 300 and/or seat 200. The toilet 100 may include weight sensors to detect the user's weight on the platform 120 and move from an optimal position for initially sitting down to another position optimal for passing excreta.

In various exemplary embodiments, the frame 110 and seat lift are internal to the toilet 100 rather than an external add-on. It also creates a customizable lifting motion set to a person's preferences. This means that the toilet 100 can look and feel mostly like a normal toilet 100, but it also can help prevent falls by keeping a person more supported during a lift and help them to their feet at an appropriate height.
Referring to
In various exemplary embodiments, the toilet continuously measures weight load on both the seat 200 and the foot platform 120. In a preferred embodiment, the system weighs the user on the foot platform 120 prior to the user placing any weight against the seat 200 and records that as the user's total weight. In some embodiments, the system calculates a user total weight using both the seat weight sensors 203 and foot platform weight sensors 121 after the user seated with the seat 200 fully lowered. In various exemplary embodiments, the system calculates the percentage of user body weight on the foot platform 120. The angle of the seat 200 is limited from raising based on the percentage of weight on the foot platform 120. This prevents the seat 200 from tipping to an angle that will not support the user's weight prior to the user being on their feet.
Referring still to
In accordance with the present disclosure, a design for a seat 200 that can be easily added/removed from a toilet, seat topper, seat lifter, etc. is provided. This allows for easier installation of a new seat 200 to accommodate upgraded seats and/or seat sensors. Referring to
In various exemplary embodiments, the bowl 300 floats on weight sensors which makes it possible to weigh excreta in the bowl 300. In such embodiments, the bowl 300 does not support the seat 200, lid 101, or any other components of the toilet 100. In a preferred embodiment, the weight sensors 302 are located between the bowl actuators 301 (see
In various exemplary embodiments, a default position for the bowl and/or seat may be selected by the user. In such embodiments, the system will return to this position after being used by someone with a different preferred or optimal position. In various exemplary embodiments, the smart toilet may be programmed with separate default configurations for children and adults.
Preferably, the actuators are controlled by a digital controller that coordinates the actions of the actuators to thereby provide a smooth lifting and lower at the desired speed. More preferably, the controller is programmable, so that users can program the lifting and lowering of the seat to their preference. Even more preferably, the toilet includes a user identification module, so that the user is automatically identified as he or she approaches or sits on the toilet.
In accordance with the present disclosure, a smart toilet that includes mechanical, hydraulic, power, and data connections to accommodate a combination of health measuring tools is provided. An electrical connection to provide power to the health measuring tools is also provided.
In various exemplary embodiments, the smart toilet includes at least one imaging sensor that captures and analyzes at least one image of a user. A processor analyzes the image data to attempt to compare the user to known users for identification purposes. If a known user is identified, the position of the bowl and/or seat is automatically adjusted to the preferred position of the user. If the user is unknown or does not have a record preferred position, the processor analyzes the physical characteristics of the user (e.g., height, waist height, length of upper and lower legs) and adjusts the position of the bowl and/or seat accordingly. In some embodiments, facial recognition is used to identify users.
In various preferred embodiments, the system may identify a user based on their face, hand, or foot. In various preferred embodiments, the image sensor includes a 3D camera. The 3D camera can be used to create an image of the user's body. With proper calibration, such as taking the image at a known distance, the length of major bones may be calculated and used to customize the toiler position for an unknown user.
In various exemplary embodiments, the toilet system includes sensors for measuring the user's weight. This includes separate sensors for determining user weight on the seat and user weight on the user's feet. The user's weight that is supported by their feet is preferably measured using a platform adjacent to the toilet on which the user's feet are placed while sitting and while being lowered or raised from the toilet.
In the preferred embodiments, the toilet also includes health assessment devices supported by the frame. Examples of such devices include imaging sensors, spectrometers, volume measurement devices, weight sensors, temperature gauges, chromatography devices, electrochemical sensors, and gas analyzers. Toilets with such devices are described in the patents and published applications cited in the Background section above.
In various exemplary embodiments, the seat and bowl may be lifted together such that the toilet may be used as a urinal. In such a configuration, the system may be designed to flush with a reduced volume of water.
All patents, published patent applications, and other publications referred to herein are incorporated herein by reference. The invention has been described with reference to various specific and preferred embodiments and techniques. Nevertheless, it is understood that many variations and modifications may be made while remaining within the spirit and scope of the invention.
