Quick-Replaceable Micro-Switch in Computer Mouse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer mice have fixed micro-switches that cannot be easily replaced, limiting the adjustment of tactile sensation and button tactility to personal preferences, and requiring the entire device to be discarded when the micro-switch expires.
Innovation Solution
A computer mouse design with a quick-replaceable micro-switch system, featuring a main body, switch holder, micro-switch, and covering panel, allowing users to easily access and replace the micro-switch by removing the covering panel and using a pincer to extract the switch holder and micro-switch, enabling adjustment of tactile sensation and extending the device's lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the micro-switch is fixedly mounted in the computer mouse, then the structural stability is improved, but the ease of replacement deteriorates
Solution Approach 1:
The patent divides the micro-switch assembly into separable components: the micro-switch body and the switch holder. The switch holder remains fixed in the mouse body providing structural stability, while the micro-switch can be independently removed by pulling its protruding terminals. This segmentation allows the micro-switch to be replaced without replacing the entire mouse or the switch holder, resolving the contradiction between structural stability and ease of replacement.
2Device complexity
If the micro-switch is fixedly mounted in the computer mouse, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The patent introduces a dynamic replacement capability where the micro-switch can be exchanged between different models (e.g., different click forces, travel distances) while keeping the switch holder and overall mouse structure fixed. This allows users to adapt the mouse to different tactile preferences and usage scenarios without redesigning the entire device, thus improving adaptability while maintaining simplicity.
Solution Approach 2:
The switch holder is designed with a universal receiving space that can accommodate different types of micro-switches with varying characteristics. This universal design allows a single mouse body to support multiple micro-switch configurations, enabling users to choose different tactile sensations based on personal needs while keeping the overall device structure simple and unchanged.
3Ease of manufacture
If the micro-switch is fixedly mounted in the computer mouse, then the manufacturing cost is reduced, but the loss of time deteriorates
Solution Approach 1:
The micro-switch is pre-equipped with protruding terminals that extend beyond its bottom surface, and the switch holder is pre-designed with a corresponding receiving space. This preliminary design preparation allows the micro-switch to be quickly grasped by its terminals and removed without requiring special tools or complex disassembly procedures, significantly reducing the time needed for replacement while keeping manufacturing simple and cost-effective.

AI summary
A computer mouse with quick-replaceable micro-switch includes a main body, a switch holder, a micro-switch and a covering panel. The main body has a lower housing, an upper housing, and an accommodation chamber formed therein. The accommodation chamber is formed with an opening on a top portion thereof. A circuit board is disposed in the main body, and has a plurality of conducting members. The switch holder is disposed in the accommodation chamber of the main body. The micro-switch is received in a receiving space of the switch holder, and has a plurality of terminals which are contacted with the conducting members. When the covering panel is removed, the micro-switch in the receiving space of the switch holder can be replaced quickly from the opening. Therefore, a user can replace the micro-switch quickly to adjust a tactile sensation when pressing the button according to personal needs.
