Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional mouse device with a single sensing module is used, then the structure is simple, but it cannot operate effectively on transparent working surfaces
Solution Approach 1:
The mouse device is segmented into multiple sensing modules, each designed to work with specific types of working surfaces. The first sensing module is optimized for transparent surfaces while the second sensing module is optimized for non-transparent surfaces, allowing the device to adapt to different surface types without requiring a complete redesign.
Solution Approach 2:
The mouse device achieves multi-functionality by incorporating multiple sensing modules that can handle different working surface types. The switching module enables the device to universally operate on both transparent and non-transparent surfaces by selecting the appropriate sensing module for each surface type.
2Adaptability or versatility
If multiple sensing modules are included to support different working surfaces, then adaptability improves, but device complexity increases
Solution Approach 1:
The mouse device incorporates dynamic switching capability through the switching module, which can dynamically select between the first and second sensing modules based on the detected working surface type. This dynamic adaptation allows the device to optimize its performance for each surface type while maintaining a unified device structure.
Solution Approach 2:
The switching module is configured to automatically detect the working surface type and autonomously select the appropriate sensing module without requiring manual intervention from the user. This self-service mechanism simplifies the user experience while managing the complexity of multiple sensing modules.
3Measurement precision
If the light beam transmission through transparent surfaces is allowed, then the sensing module can detect surface features, but the displacement signal generation becomes ineffective
Solution Approach 1:
The first sensing module is specifically designed with local quality optimized for transparent surfaces, using optical characteristics that are reflected or scattered by transparent materials rather than transmitted through them. This allows the sensing module to effectively detect surface features and generate accurate displacement signals even when working with transparent surfaces.

Implementation Method 1
The light-emitting element 161 is disposed on the circuit board 15. Moreover, the light-emitting element 161 emits a light beam B.
Implementation Method 2
After the light beam B passes through the optical assembly 162, the light beam B is refracted by the optical assembly 162. Consequently, the light beam B is projected onto the working surface T
Implementation Method 3
After the light beam B reflected by the working surface T is received by the optical sensor 163, a displacement signal is generated by the optical sensor 163 according to the light beam B

AI summary
A mouse device includes a mouse casing, a circuit board, a first sensing module, a second sensing module and a switching module. The circuit board is disposed within the mouse casing. Both of the first sensing module and the second sensing module are disposed on the circuit board and partially exposed outside the mouse casing. The switching module is partially exposed outside a base of the mouse casing. The first sensing module or the second sensing module is exposed outside the base under control of the switching module. Consequently, a moving resolution of the mouse device is adjustable according to the practical requirements. The switching module has a simple mechanism for changing the moving resolution of the mouse device in a simple manner.
