Cable-Actuated Faucet Valve Control for Hands-Free Water Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water faucet systems require manual or electrical operation, risking contamination with pathogens and inefficient water use, especially when extended operation is needed, as they often require wiring and power, which may not be feasible or practical in all installations.
Innovation Solution
A cable-connected lever system that allows users to control water flow without touching the faucet, using floor or wall-mounted levers activated by feet or elbows, reducing contamination risk and enabling water conservation by allowing hands-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual or electrical faucets are used, then water flow control is achieved, but users risk contamination with pathogens when touching the faucet
Solution Approach 1:
The patent introduces a foot pedal as an intermediary control mechanism between the user and the water faucet. The foot pedal is connected to the faucet via a cable linkage system, allowing users to control water flow without direct contact with the faucet handle. This intermediary device effectively breaks the transmission path for pathogens while maintaining operational control.
Solution Approach 2:
The patent replaces the traditional electrical or direct mechanical faucet control system with a foot-operated mechanical linkage system. By using a cable-connected foot pedal mechanism, the system eliminates the need for electrical components or direct hand contact, substituting a purely mechanical foot-actuated system that achieves hands-free operation.
2Object-affected harmful factors
If electrical sensors and wiring are added to enable hands-free operation, then pathogen contamination is reduced, but installation complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates all electrical components (sensors, wiring, power sources) from the hands-free faucet control system. By removing these complex electrical elements entirely and replacing them with a simple foot pedal and cable linkage, the system achieves hands-free operation without any electrical infrastructure, thereby reducing installation complexity and cost.
Solution Approach 2:
The patent employs simple, inexpensive mechanical components (foot pedal, cable, linkage) instead of expensive electrical sensor systems. These basic mechanical parts are readily available, easy to install, and do not require ongoing electrical infrastructure, making the solution both cost-effective and simple to implement in existing installations.
3Reliability
If water flows continuously for extended periods, then thorough cleaning is enabled, but water waste increases
Solution Approach 1:
The patent enables dynamic control of water flow through the foot pedal mechanism. Users can adjust the degree of depression of the foot pedal to modulate water flow rate, and can easily stop flow by releasing the pedal. This dynamic control allows water to flow at higher rates when thorough cleaning is needed, then be quickly stopped to prevent waste, adapting to the actual cleaning requirements.

Function Achieved in This Case
The system effectively reduces the risk of pathogen transmission and conserves water by allowing hands-free operation of faucets and showers, being retrofittable to existing installations without the need for extensive electrical modifications or power sources.

AI summary
An apparatus and kit are provided for remotely controlling the flow of a valve in a faucet or shower. The user may remotely control flow by actuating a foot pedal, which pulls a cable causing the valve to open. When the cable is released, springs force the valve closed. Temperature may be remotely controlled as well by the actuation of a separate foot pedal, in which rotation of the foot pedal is transferred by cables to cause rotation of the valve and the corresponding temperature change of the flow.
