Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mouse devices have a fixed wheel module design, limiting users' ability to replace the wheel module with different sizes or appearances based on personal preferences or usage habits.
Innovation Solution
A mouse device design featuring a housing with an outer accommodating slot for a detachable wheel module, which includes a mounting base and a wheel connected via pivots, utilizing magnetic or engaging structures for fixation and an optocoupler component for rotation detection, allowing for interchangeable wheel modules of various sizes and materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wheel module has fixed appearance and size, then the structure is simple and easy to manufacture, but users cannot replace it with different sizes or appearances to meet personal preferences
Solution Approach 1:
The wheel module is designed as a separate, detachable component from the housing. The housing includes an accommodating slot that can receive different wheel modules, allowing the wheel module to be segmented as an independent replaceable unit. This enables users to replace wheel modules with different sizes or appearances without modifying the entire mouse structure.
Solution Approach 2:
The accommodating slot in the housing is designed with universal dimensions and positioning features that can accommodate multiple types of wheel modules. The slot structure includes positioning portions that work with corresponding positioning features on different wheel modules, creating a universal interface that supports various wheel module specifications while maintaining a consistent housing design.
2Adaptability or versatility
If the wheel module is detachably disposed in the outer accommodating slot, then users can customize with different sizes and appearances, but the housing structure becomes more complex
Solution Approach 1:
The wheel module is designed as a separate, detachable component from the housing. The housing includes an accommodating slot that can receive different wheel modules, allowing the wheel module to be segmented as an independent replaceable unit. This enables users to replace wheel modules with different sizes or appearances without modifying the entire mouse structure.
Solution Approach 2:
The housing is pre-designed with an accommodating slot and positioning portions that are prepared in advance to receive specific wheel module configurations. The positioning portions are pre-formed in the housing structure, and corresponding positioning features are pre-formed on the wheel modules, enabling straightforward assembly without complex adjustment or customization during manufacturing or assembly processes.
3Reliability
If fixing structures are added to secure the wheel module, then the wheel module remains stable during use, but the device complexity increases
Solution Approach 1:
The fixing structure is merged with the positioning portions of the accommodating slot. The positioning portions serve dual functions: they guide the wheel module into the correct position during assembly and provide fixation to secure the wheel module during use. This integration eliminates the need for separate fixing mechanisms, maintaining structural simplicity while ensuring reliable wheel module retention.
Solution Approach 2:
The positioning portions and corresponding positioning features on the wheel module create a self-fixing mechanism. When the wheel module is inserted into the accommodating slot, the positioning portions automatically engage with the positioning features, providing both positioning and fixation without requiring additional active fixing components or complex assembly steps. The structure self-secures the wheel module through its geometric design.
