Height- and Width-Adjustable Mouse Support for Hand and Wrist Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer mice cause discomfort and fatigue in the hand, wrist, and shoulder due to prolonged use, leading to conditions like cumulative trauma disorder and repetitive strain injuries, and existing support devices restrict arm and shoulder mobility.
Innovation Solution
An adjustable supporting assembly for an ergonomic mouse with height, width, and finger adjustment members that can be coupled to a conventional mouse, providing customizable support for the palm, fingers, and knuckles, allowing for varied hand and shoulder movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional mouse is used, then the device is simple and easy to operate, but it causes discomfort and fatigue in the hand, wrist, and shoulder due to prolonged use
Solution Approach 1:
The patent introduces an adjustable supporting assembly as an intermediary device between the user's hand and the conventional mouse. This assembly includes support members positioned to support the palm, fingers, and knuckles, thereby mediating the interaction and reducing direct stress on vulnerable areas while maintaining normal mouse operation
Solution Approach 2:
The supporting assembly features adjustable parameters including height adjustment members, width adjustment members, and angular orientation adjustment members. These allow users to customize the support configuration to match their anatomical dimensions and preferences, optimizing comfort and reducing strain through parameter customization
2Object-affected harmful factors
If stationary palm rests are used to support the hand, then hand support is provided, but arm and shoulder mobility is restricted
Solution Approach 1:
The patent implements dynamic adjustability in the supporting assembly, allowing users to modify height, width, and angular orientation according to different task requirements and personal preferences. This dynamic configuration enables the support structure to adapt to varying arm and shoulder positions without restricting mobility
Solution Approach 2:
The supporting assembly is divided into multiple independent adjustment components: height adjustment members, width adjustment members, and angular orientation adjustment members. Each segment can be independently adjusted, providing fine-grained control over the support configuration while maintaining overall flexibility and arm mobility
3Ease of operation
If the palm is placed on the mouse while hovering fingers, then mouse operation is enabled, but tendons, nerves, and muscles in the back of the hand, wrist, and forearm are subjected to chronic stress
Solution Approach 1:
The supporting assembly acts as an intermediary structure that bears the weight and stress of the palm and hand, preventing direct transmission of chronic stress to the tendons, nerves, and muscles in the back of the hand, wrist, and forearm. The finger support members specifically cradle the fingers, reducing muscle tension while maintaining operational capability

AI summary
The present invention discloses an adjustable supporting assembly for a user of a conventional mouse, and an ergonomic adjustable computer mouse. The adjustable supporting assembly comprises at least one height adjustment member adapted to be coupled on a body of the conventional mouse for palm comfort. The adjustable supporting assembly also comprises at least one finger adjustment member protruding laterally from the at least one height adjustment member for finger support. The adjustable supporting assembly comprises a width adjustment member configured to extend laterally. The width adjustment member comprises a receptacle member for placing the conventional mouse, the receptacle member includes a plurality of holes for incorporating screws and a pair of adjusting plates attached to a base of the receptacle member, each of the pair of adjusting plates having a slot to incorporate a screw to be extended laterally along the slot.
