Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torque increasing systems are inadequate for individuals with dexterity limitations, as they do not provide sufficient leverage or grip enhancement to effectively operate actuators like faucets.
Innovation Solution
A torque increasing system comprising a grip with a continuous convexly arcuate perimeter wall and a removably mounted coupler, which includes pivotably coupled segments and a locking mechanism, along with a handle that extends from the coupler, allowing for improved grip and leverage by securing the coupler to the grip and rotating it to control the faucet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a standard grip is used for faucet actuators, then the device is simple and easy to manufacture, but individuals with dexterity limitations cannot apply sufficient torque to operate it
Solution Approach 1:
The coupler is divided into multiple segments (first segment and second segment) that can pivot relative to each other, allowing the structure to adapt to the grip's geometry while maintaining structural integrity for torque transmission
Solution Approach 2:
The coupler extends around the perimeter wall in a three-dimensional configuration, wrapping around the grip to create multiple contact points and distribute forces across different spatial dimensions, thereby increasing mechanical advantage
2Adaptability or versatility
If the coupler is made removable and adaptable to different grips, then versatility is improved, but device complexity increases
Solution Approach 1:
The coupler incorporates pivotable segments that can dynamically adjust their relative positions to accommodate different grip geometries, while the locking member provides a simple mechanism to secure the adaptively configured coupler to the grip
Solution Approach 2:
The coupler is designed to wrap around and nest along the perimeter wall of the grip, with segments that can pivot to conform to the curved surface, creating an adaptive fit without requiring complex customization for each grip type
3Force
If the handle length is increased to provide more leverage, then torque is improved, but the distance of coupler movement increases
Solution Approach 1:
The coupler segments feature convexly arcuate interior surfaces that conform to the curved perimeter wall of the grip, creating a compact wrapped configuration that maximizes leverage through the handle while minimizing the radial distance the coupler extends from the grip center
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides enhanced grip and leverage, enabling individuals with dexterity limitations to easily operate faucets by reducing the distance of coupler movement and securing it with a locking mechanism, facilitating efficient water flow control.
Implementation Method 1
The interior surfaces of the first and second segments abut the grip in the closed condition. The coupler includes a locking member. A locking member is attached to the first ends of the first and second segments to releasably lock the coupler in the closed condition and in frictional engagement with the grip.

AI summary
A faucet actuator torque increasing system and method for increasing torque applied to an actuator includes a grip. The grip has a perimeter wall with a continuous convexly arcuate shape. A coupler is removably mounted on the perimeter wall of the grip. The coupler includes a first segment and a second segment which are pivotably coupled to each other via a connector. The first and second segments move between a closed condition engaging the grip and an open condition for disengaging the grip. Each of the first and second segments has an interior surface. The interior surfaces abut the grip in the closed condition. A locking member releasably locks the coupler in the closed condition. A handle is integrally attached to and extends away from the coupler. A stop is attached to the coupler to abut against the grip when in the closed condition.
