Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manufacturing methods are used to produce mouse buttons and switches, then production cost and time are controlled, but tolerance gaps arise between button and switch surfaces, causing delayed and dull feedback
Solution Approach 1:
An elastic member is introduced as an intermediary component between the button and the switch. This elastic member compensates for manufacturing tolerance gaps by elastically deforming to ensure precise contact between the button's pressing surface and the switch's actuating surface, thereby resolving the contradiction between manufacturing precision and ease of manufacture.
Solution Approach 2:
The elastic member changes the physical state and mechanical properties between the button and switch interfaces. By utilizing elastic deformation parameters, the system adapts to tolerance variations and maintains consistent contact pressure, improving contact precision without complicating the manufacturing process.
2Reliability
If elastic members are added to eliminate tolerance gaps, then button sensitivity and feedback clarity are improved, but device complexity increases
Solution Approach 1:
The elastic member is designed as a flexible component that can be integrated into the existing button and switch assembly. Its flexibility allows it to conform to slight misalignments and provide reliable contact, while its simple structure does not significantly increase overall device complexity.
Solution Approach 2:
The elastic member is designed to self-adjust and self-compensate for tolerance gaps through its elastic deformation. This self-service mechanism eliminates the need for complex adjustment mechanisms or precision manufacturing, thereby improving reliability without substantially increasing device complexity.
3Productivity
If traditional assembly methods are used, then assembly simplicity is maintained, but tolerance gaps result in idle stroke and delayed response during rapid clicking
Solution Approach 1:
The elastic member performs preliminary action by pre-compressing and pre-positioning itself between the button and switch during assembly. This preliminary positioning ensures that when the user presses the button, the contact between the pressing surface and actuating surface is immediate and accurate, eliminating idle stroke and improving response speed during rapid clicking.
Solution Approach 2:
The elastic member introduces dynamic adjustment capability to the static assembly. Through elastic deformation, the member dynamically adapts to the pressing force and maintains optimal contact during rapid operations, thereby improving productivity and ease of operation simultaneously.

AI summary
A mouse structure includes a shell, a control circuit, a button and an elastic member. The shell includes a base and an upper cover. A boss extends from the upper cover towards the base. The control circuit includes a circuit board and a switch arranged thereon. The button comprises a hollow cylindrical body extending through the upper cover and having a pressing surface and a stop surface opposite each other. The elastic member comprises an embedded section snapped to the boss, a pressing part and an elastic part. The elastic part being connected between the embedded section and the pressing part and extending through into the hollow cylindrical body. The pressing part is elastically pressed against the stop surface to pull down the hollow cylindrical body, so that the pressing surface is attached to a surface of the switch.
