Adjustable Weight Computer Mouse for Stability and Fatigue Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic pointing devices, such as mice, have fixed weights that do not accommodate user preferences for different feel and application-specific requirements, leading to instability and fatigue during extended use, particularly in gaming.
Innovation Solution
An electronic pointing device with a housing that allows users to adjust the weight by adding or removing ballast elements, using a frame, interchangeable covers, or donut-shaped weights, to customize the weight and center of gravity for optimal hand feel and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mouse weight is increased to improve stability and control, then the mouse feels more stable and easier to control, but the mouse becomes more fatiguing during extended use
Solution Approach 1:
The mouse weight system is segmented into modular components: a base weight integrated into the housing and interchangeable weight inserts that can be added or removed. This allows users to divide the total weight into manageable segments, selecting the appropriate combination for their specific needs - heavier inserts for stability during gaming, lighter or no inserts for reduced fatigue during extended office work.
2Ease of manufacture
If the mouse weight is fixed at manufacturing to simplify production, then manufacturing complexity is reduced, but the device cannot accommodate different user preferences and application requirements
Solution Approach 1:
The mouse transitions from a static weight configuration to a dynamic, adjustable system. A weight selection mechanism with multiple positions allows the total weight and center of gravity to be dynamically changed based on user preference and application requirements. The mechanism maintains a fixed, simplified housing structure while enabling weight variation through interchangeable inserts and adjustable positioning.
3Adaptability or versatility
If interchangeable weight components are added to allow weight adjustment, then user customization is enabled, but device complexity increases
Solution Approach 1:
The interchangeable weight inserts serve multiple functions simultaneously: they adjust the total mouse weight, modify the center of gravity position, and can be designed with different densities to achieve various weight distributions. The housing incorporates a universal weight selection mechanism that accommodates different insert configurations without requiring separate mechanisms for each adjustment type.
