Computer Mouse Wrist Support with Adjustable Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer mouse accessories fail to provide efficient adjustment for hand positioning, particularly in terms of distance and height, which is crucial for maintaining ergonomic correctness and preventing repetitive motion injuries such as carpal tunnel syndrome.
Innovation Solution
A computer mouse assembly with a wrist supporting subassembly featuring adjustable support members and compression springs that allow for customizable height adjustment, ensuring the hand and wrist are in ergonomic positions, accommodating various hand sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed hand positioning device is used, then the structure is simple, but it cannot accommodate users with different hand sizes and provides insufficient adjustability
Solution Approach 1:
The wrist support subassembly is designed with movable support members that can be adjusted to different positions along the mouse body. The support members are held in place by friction between the tapered surfaces and the mouse body, allowing dynamic adjustment while maintaining stability during use.
Solution Approach 2:
The wrist support is divided into multiple independent support members that can be positioned separately. Each support member can be adjusted independently to accommodate different hand sizes and positioning requirements, providing modular adaptability.
2Adaptability or versatility
If adjustable support members are added, then adaptability improves, but the device complexity increases
Solution Approach 1:
The support members feature tapered surfaces that create friction-based locking when pressed against the mouse body. This allows the supports to be easily adjusted to different heights by the user's hand weight and pressure, then automatically locked in position without requiring additional fasteners or complex mechanisms.
Solution Approach 2:
The wrist support system uses the user's own hand weight and adjustment pressure to engage and lock the support members in position. The friction between the tapered surfaces and the mouse body provides automatic positioning and securing, eliminating the need for separate locking mechanisms.
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 solution effectively reduces the risk of repetitive motion injuries by allowing users to adjust the hand support to a comfortable position, promoting proper alignment and minimizing strain on the wrist and forearm during prolonged computer use.
Implementation Method 1
at least one compression spring may be configured to exert an upward force on the user wrist support subassembly to raise the user wrist support subassembly with respect to the computer mouse body when selective vertical positioning is enabled by the attachment hardware subassembly
