Telescoping Gel Wrist Support for Neutral Mouse Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer pointing devices, such as mice and trackballs, cause wrist strain and discomfort due to repetitive movements and inadequate wrist support, contributing to conditions like Carpal Tunnel Syndrome, as existing solutions either increase drag, are physically obtrusive, or fail to maintain a neutral wrist position during use.
Innovation Solution
A telescoping gel pad wrist support integrated within the pointing device, allowing adjustable extension and retraction to accommodate individual wrist positions, with a gel pad for comfort and reduced friction, ensuring neutral wrist alignment and minimizing operational interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stationary gel pad support is used independently of the pointing device, then wrist support is provided, but the support is limited and incomplete when the mouse is moved
Solution Approach 1:
The gel pad wrist support is integrated with the pointing device housing to form a unified structure. The support extends from the housing and moves together with the device, ensuring continuous wrist support during mouse operations. This merging eliminates the limitation of stationary independent supports and provides adaptive support that follows the device movement.
Solution Approach 2:
The wrist support is designed to be dynamic rather than static. It can extend and retract relative to the housing, and its position adjusts as the mouse moves. This dynamic characteristic allows the support to maintain effectiveness during device movement, contrasting with fixed stationary supports that become misaligned during operation.
2Adaptability or versatility
If the wrist support extends from the pointing device, then adjustable wrist position accommodation is achieved, but the support may increase drag on the device
Solution Approach 1:
The wrist support incorporates a gel pad within a flexible housing structure that can extend and retract. The gel pad itself is a soft, flexible material that provides wrist support while minimizing friction and drag. The flexible construction allows the support to move with the device without creating excessive resistance during mouse operations.
3Adaptability or versatility
If a telescoping gel pad wrist support is integrated within the pointing device, then adjustable extension and retraction accommodate individual wrist positions, but the device complexity increases
Solution Approach 1:
The gel pad wrist support is nested within the pointing device housing. The support can extend from and retract into the housing, creating a telescoping structure. This nesting arrangement accommodates individual wrist positions while keeping the support mechanism integrated and relatively compact, managing the complexity by organizing components within the existing device footprint.
4Adaptability or versatility
If the wrist support is integrated with the pointing device, then the support moves with the device, but the manufacturing complexity increases
Solution Approach 1:
The integrated wrist support system is divided into separable components: the housing structure, the gel pad, and the telescoping mechanism. This segmentation allows each component to be manufactured independently using standard processes, then assembled together. The modular approach reduces manufacturing complexity compared to creating a fully integrated monolithic structure.

AI summary
A computer controlled pointing device having, a telescoping wrist support integral with and associated with the pointing device, so as to permit adjustable extension and retraction from the pointer device housing, to accommodate the preferred support position of an individual user's wrist. The means from effecting such adjustable incremental extension and retraction of the wrist support includes coupling means for releasable locking of the wrist support in a fixed position relative to the housing of the pointing device.
