Hinged Wrist Rest for Ergonomic Mouse Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer mouse wrist or palm rest designs fail to provide effective support during fast and long movements, as they are either stationary, interfere with mouse movement, or cause irritation, and do not allow for ergonomic lifting of the mouse while maintaining wrist support.
Innovation Solution
A hinged wrist or palm rest attached to the mouse, allowing it to lift off the surface without lifting the wrist, with options for rigid or flexible hinges to accommodate various motion ranges and user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wrist rest is rigidly attached to the mouse, then the wrist support stability is improved, but the mouse lifting capability deteriorates
Solution Approach 1:
The patent applies a hinged connection between the wrist rest and mouse body, allowing the wrist rest to dynamically adjust its position. The hinge enables the wrist rest to remain stable during normal use while allowing smooth movement during mouse lifting, resolving the contradiction between stability and ease of operation.
2Stability of the object's composition
If the wrist rest is stationary on the table surface, then the wrist support position is fixed, but the mouse movement freedom deteriorates
Solution Approach 1:
The wrist rest is connected to the mouse body through a hinge mechanism, transforming it from a stationary object to a dynamic one that moves with the mouse. This allows the wrist rest to maintain proper support position while adapting to mouse movements, eliminating the trade-off between position stability and movement freedom.
3Measurement precision
If the wrist rest is attached directly to the wrist like a bracelet, then the wrist support position is precise, but the wrist irritation increases
Solution Approach 1:
The patent extracts the wrist rest from direct contact with the wrist, positioning it on the mouse body instead. This eliminates the bracelet-like constraint that causes irritation while maintaining precise wrist support through the mouse's movement, resolving the contradiction between position precision and comfort.
4Device complexity
If the floating wrist rest is used, then the wrist support simplicity is improved, but the position stability deteriorates
Solution Approach 1:
The patent transforms the floating wrist rest into a dynamically connected one through the hinge mechanism. This maintains the simplicity of having no additional attachments while providing stable position through the hinge's mechanical connection to the mouse body, resolving the contradiction between simplicity and stability.

AI summary
An ergonomic hand support device reduces stress and helps to prevent strain when using a computer pointing device. Attaching the hand support to the mouse with a hinge allows the mouse to lift up off of the surface while the wrist is still being supported.
