Atty. Docket No.: 24-026PCTDEVICES, SYSTEMS, AND METHODS FOR REMOTELY CONTROLLING WATER CONTROLSCROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims benefit of U.S. Provisional Patent Application Serial No. 63 / 730,032, filed December 10, 2024, the disclosure of which is incorporated herein by reference.BACKGROUND
[0002] The following information is provided to assist the reader in understanding technologies disclosed below and the environment in which such technologies may typically be used. The terms used herein are not intended to be limited to any particular narrow interpretation unless clearly stated otherwise in this document. References set forth herein may facilitate understanding of the technologies or the background thereof. The disclosure of all references cited herein are incorporated by reference.
[0003] There is an unmet need for equipment to assist individuals with mobility impairments with bathing and toileting. This shortfall limits an individual’s ability to perform essential activities of daily living (ADL) such as bathing, and, therefore, to live independently at home. The most comprehensive data demonstrating this fact comes from a national US survey indicating that 42% of older adults with disabilities do not have the bathing and toileting equipment they need, which translates to 5 million individuals who lack the necessary supports to perform ADLs to live safely and independently at home. Lam K, Shi Y, Boscardin J, Covinsky KE. Unmet need for equipment to help with bathing and toileting among older US adults. JAMA Internal Medicine. 2021;181(5):662-70. Research highlights the potential of low-cost interventions, such as grab bars and tub benches, to reduce injuries, foster independence, preserve dignity, and enhance overall quality of life of older adults and individuals with disabilities. See, for example, Rinaldo, F., Altman, M., Cannon, K., Platchek, T., Shah, N. R., Kaplan, R. M., & Milstein, A. (2020). Slowing Medicare spending by optimizing late-life needs. NEJM Catalyst Innovations in Care Delivery, 1(4) and Lam K, Shi Y, Boscardin J, Covinsky KE. Unmet need for equipment to help with bathing and toileting among older US adults. JAMA Internal Medicine. 2021; 181 (5):662-70.Atty. Docket No.: 24-026PCT
[0004] Considering the general need for low-cost interventions and assistive technology to assist with ADLs, there is an identified unmet need when it comes to managing, for example, the shower / bath water controls and other water controls, for older adults and individuals with mobility impairments. For example, anyone in those demographics that use shower chairs and transfer benches to bathe and have difficulty moving or standing quickly in the event of an emergency like tap water scalding, or to turn on / off and adjust water temperature from a seated position, would greatly benefit from assistive technologies. Wall-hung shower chairs are commonly attached to the back wall opposing the shower head and removable transfer benches are commonly placed near the rear of the tub (typically for caregiver access to assist with bathing in the front or for ease of transfer on / off the bench), which can make adjusting the existing temperature control difficult. In that regard, reaching or standing to change the temperature and / or flow can be physically strenuous, be impossible due to lack of strength or function, or significantly increase the risk of a fall.
[0005] Controlling whether the shower valve is on or off, or adjust the temperature for convenience or to prevent a burn from tap water scalding becomes difficult if the shower valve control is not easily accessible, whether by distance or limited mobility' that prevents total or quick adjustment (without an injury or fall). Tap water scalding is an identified issue among older adults where it can be caused by “slipping and falling in the bathtub and not being able to get up, not checking the water temperature before getting into the tub or shower, or possible water temperature changes as water may be used in other parts of the home while showering.” Grant, Ernest J. MSN, RN, FAAN. Preventing Burns in the Elderly. A Guide for Home Healthcare Professionals. Home Healthcare Nurse 3 l(10):p 561-573, November / December 2013. | DOI: 10.1097 / 01.NHH.0000436217.56972.58.
[0006] It is desirable to develop assistive technologies to reduce or eliminate some of the problems experienced by those who have difficulty in accessing a water control.SUMMARY

Docket No.: 24-026PCT
[0054] As used herein, the term “approximately” when used in connection with a value means within 5%, within 2%, or within 1% of the value unless otherwise indicated herein or otherwise clearly contraindicated by the text. As used herein the term “and / or” means one of or both of an entity. Thus, A and / or B means A or B, or both A and B.
[0055] As described above, individuals with mobility impairments and / or other individuals (who may not suffer impairment) may, for example, have difficulty in controlling plumbing or water controls (that is, control valves or control elements) on plumbing fixtures in various locations (for example, faucets, bathtub / shower water controls, etc.). For example, seated individuals struggle to reach traditional shower controls but want the independence and comfort of controlling the water. Remote control systems hereof allow one or more water controls or control elements to be controlled from a preferred location remote from an existing / installed control fixture while retaining the existing control fixture. The remotely operable systems hereof facilitate access for multiple users including, for example, individuals with mobility impairments, caregivers, other household occupants, etc. For households with multiple individuals that, for example, share the same bathroom, the existing fixtures, valves or control elements remain fully functional. In that regard, the existing control elements retain their original functionality after installation of a remotely operable system hereof. Therefore, an individual who does not require or benefit from a system hereof can still use the control valves or control elements in a normal or typical manner. For caregivers, a remote or satellite unit hereof may, for example, be positioned outside of a bathing area to keep the individuals for whom they care safe and comfortable, maintaining privacy and avoiding the need for the caregiver to enter the bathing area or get wet. The systems hereof may be used in any situation in which it is desirable to remotely control a valve or control element of a plumbing control fixture, wherein the plumbing control fixture is located. The systems are particularly useful for individuals with mobility impairment, caregivers of individuals with mobility' impairment, and other individuals who must use control fixtures in connection with which a system hereof has been installed.
[0056] In a number of embodiments, remote water control devices, systems and methods hereof provide a modular, easily removable solution to control, for example, one or more water control elements of a water control fixture in, for example, a bathing area or stall (that is, a bathtub and / or shower area or stall) from a remote position without requiring the user to reach for the installed / fixed controls or control fixtures (to, for example, control water temperatureAtty. Docket No.: 24-026PCTof a shower or turn the water on or off). In that regard, one or more control fixtures (which may, for example, be fixed in place in a bathing area) are provided to control plumbing valves to control pressure and flow of hot and / or cold water from a faucet. The relative control of flow of hot and cold water from the plumbing system controls temperature of the water flowing from the faucet. The control fixture(s) include control elements such a handles, levers, knobs etc. which may be moved by a user in a controlled manner to control water flow and water temperature. Many modern control fixtures include a single control element (for example, a handle or lever) to control flow and water temperature. However, a single control fixture can include multiple control elements that may operate in different manners (for example, a handle or knob to control water flow and a lever to control temperature). Further, multiple control fixtures may be provided. Recently, control fixtures with control element including electronic circuitry for control of electronic valves have become available. The systems hereof are readily adapted using well-known engineering principles to provide remote control of any type of control fixture system.
[0057] As illustrated in FIG. 1, in a number of embodiments, a system hereof includes a satellite unit configured to be installed remote from or at a spaced distance from the control element of the control fixture (for example, within or outside the bathing area). The satellite unit includes a satellite interface configured to be adjusted by a user to change a state thereof. The system further includes a transfer system in connection with the satellite interface and with the control element. The state of the control element of the control fixture is adjusted via the transfer system in response to adjustment of the state of the satellite interface by the user. The satellite unit may be readily positioned to facilitate adjustment of the state of the control fixture by an individual such as user or caregiver.
[0058] The transfer system may, for example, include a sensor to determine the state of the satellite interface and a communication system to transfer or communicate the state of the satellite interface. The control fixture may, for example, include an electronic valve system and the control element may include electronic circuitry (for example, operable as a controller to effect software-based control). The communication system may be configured to communicate information to the electronic circuitry of the state of the satellite interface, and the electronic circuitry may be configured to adjust the state of the control fixture in response thereto. An example, of a control fixture including such a control element is the Smart Shower available from Kohler Company of Kohler, Wisconsin.Atty. Docket No.: 24-026PCT
[0059] The system may further include a local unit (that is, local to the control fixture) or control unit configured to be placed in connection with the control element of the control fixture. In a number of embodiments, the control unit includes a control element interface to connect to a control element of the control fixture and a powered actuator (for example, one or more powered motors) to adjust the control element. The communication system may be configured to communicate information to the control unit of the state of the satellite interface. The local interface may be configured to adjust the control element in response thereto.
[0060] Communication of information may be effected in a wired or wireless manner. Wireless communication enables a satellite unit hereof to be located at any position. Further, multiple satellite units may be placed in connection with a local control element.
[0061] In a number of embodiments in which the system includes a control unit configured to be placed in connection with the control element of the control fixture, the control unit includes a control element interface to connect to a control element of the control fixture, and the transfer system includes a mechanical actuator system in connection with the satellite interface and with the local interface. The mechanical actuator system is configured to adjust the state of the control element of the control fixture (via connection with the control element interface) in response to adjustment of the satellite interface by the user.
[0062] A number of representative examples of systems hereof are discussed in connection with a transfer system including a mechanical actuator system to transfer force / motion between a satellite interface and a control interface. As described above, the position of the satellite unit of systems hereof may be chosen for ease of access by the user. The satellite unit includes a satellite interface configured to be contacted and adjusted / moved by the user or caregiver. The transfer system may include a mechanical actuator or actuator system connected at a first end thereof to the satellite interface and at a second end thereof to the local interface. The mechanical actuator system may transmit force resulting from movement of the satellite interface to the control element interface to cause movement of the control element interface and thereby movement of the control element of the control fixture. A number of representative embodiments hereof are discussed in connection with a control fixture including a single control element such as a handle. However, a satellite unit hereof may include multiple satellite interfaces which are independently movable by the user to independently control multiple control element interfaces via multiple, independently operating actuator systems. The multiple control interfaces may be components of a single control until. Further, interfaces upon a singleAtty. Docket No.: 24-026PCTsatellite unit may be used to one or more control interfaces of each of multiple control units. Further, multiple systems or subsystem, including pairs of satellite units and control units may be provided in a system hereof. Each of the systems may, for example, be used to remotely control an independent valve or control element of a fixture including multiple, separately controllable valves or control elements.
[0063] In the illustrated embodiment of FIG. 2, remote control of a plumbing fixture may be achieved through the use of a system 10 including two or more modular units 20 and 50. A first modular unit or control modular unit, or simply control unit 20, is placed in connection with an existing or native faucet control fixture 5. Control unit 20 may include a control element interface 22 to connect to and cooperate with a control element such as a shower valve handle 5a or other control or control element of installed shower control fixture 5 or other water control fixture. In the embodiment of FIG. 2, a second modular unit satellite unit 50 is installed or mounted at a convenient remote position (that is, at a position spaced from control unit 20) for the user within or outside the bathing or shower area. A satellite interface 54 (such as a handle) on satellite unit 50 may be moved in a controlled manner by the user or caregiver to effect corresponding motion of handle 5a of installed shower control fixture 5 (via control element interface 22). Motion from satellite interface 54 may, for example, be transferred to control element interface 22, and thereby to handle 5a, via a mechanical actuator or actuator system 60. In the illustrated embodiments, actuator system 60 is a cable-based system which includes two cables 62 (for example, Bowden, capstan, or spooled cables as known in the mechanical arts) which extend between satellite unit 50 and control unit 20. One or more guides 70 may be provided a one or more intermediate positions between satellite unit 50 and control unit 20 to organize actuator cables 62.
[0064] FIG.3 illustrates an embodiment of a system 110 hereof used in a number of studies hereof. As described above, system 110 includes a control unit 120a, which connects to and cooperates with an installed shower fixture control, and a satellite unit 120b, which is controlled directly by the user. Satellite unit 120b is placed in connection with control unit via cables 162 of actuator system 160. In the illustrated embodiment, control unit 120a and satellite unit 120b are identical in construction and can be swapped or flipped in position / functionality if required or desired. While control units and satellite units hereof may be identical or generally identical in construction in certain embodiments, as clear to one skilled in the art, they need not be identical or generally identical and may differ significantly in form, structure,Atty. Docket No.: 24-026PCTand / or function. Elements of satellite unit 120b are numbered similarly to like element of control unit 120a other than the substitution of the designation “b” after the numeral for the designation “a” in the references for satellite unit 120b. Because, in the representative embodiment of system 110, control unit 120a and satellite unit 120b are identical or generally identical in construction, not all elements of each unit are discussed specifically, or in significant detail, if such an element has been discussed in connection with the other unit.
[0065] System 110 may, for example, be installed in a shower or bathing area as described in connection with FIGS. 4 through 5B. In that regard, control unit 120a (as illustrated in FIGS. 4, 5A and 6A through 6C) may be installed over existing shower valve handle 5 a of shower control 5. Control unit 120a includes a base 122a including an opening 123a therein through which handle 5a is passed. Base 122a may be attached in place via suction cups, adhesive, connectors (for example, screws), etc. as known in the connection arts. While representative embodiments of systems 10 and 110 are illustrated for attachment to a bath / shower wall, systems hereof are readily attached to other supports such as a rail system (for example, a handicap rail system). Moreover, systems hereof may be used in connection with plumbing fixtures that are not located in a shower or bathing area. Each of control unit 120a and satellite unit 120b may, for example, be readily removable from the bathing area or other area of installation (for example, kitchen, utility room, etc.).
[0066] Control unit 120a includes a moveable element or component which is connected to a moveable element or component of satellite unit via an actuator system 160a as described further below. One or more bearings may be provided to facilitate relative motion and reduce friction in such moveable element. As used herein, the term “bearing” refers to a component that reduces friction between surfaces that move relative to each other (for example, slide, rotate, etc.). The term “bearing” includes, for example, bearings and bushings of any form or material as required by the specified use. Referring to FIG. 6A, in the illustrated embodiment, a radially outer bearing ring 124a is formed around or connected to the perimeter of opening 123a. A radially inner bearing ring 128a is formed to include two parts or components 130a and 132a in the illustrated embodiment.
