Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If switch modules are fixed on the main circuit board, then the structural stability is improved, but the ease of repair and adaptability deteriorate
Solution Approach 1:
The mouse device is divided into modular components: the main circuit board and replaceable switch modules. Each switch module is a separate unit that can be independently removed and replaced, allowing users to repair or upgrade individual components without affecting the entire device. This segmentation resolves the contradiction by maintaining structural integrity through standardized connection interfaces while enabling easy repair through modular replacement.
Solution Approach 2:
The switch modules are extracted from the main circuit board as separate replaceable units. The main circuit board contains connection interfaces (such as magnetic connectors or snap-fit mechanisms) that allow switch modules to be easily attached and detached. This extraction enables users to remove damaged switch modules for replacement while keeping the main circuit board intact, significantly improving ease of repair.
2Ease of manufacture
If switch modules are fixed on the main circuit board, then the manufacturing simplicity is improved, but the adaptability deteriorates
Solution Approach 1:
The device is segmented into a main circuit board and interchangeable switch modules, each manufactured separately using optimized processes. The main circuit board is manufactured once with standardized connection interfaces, while switch modules can be produced in different variants (e.g., different tactile feedback characteristics, optical or mechanical types). This segmentation maintains manufacturing simplicity through standardized interfaces while enabling adaptability through modular configuration.
Solution Approach 2:
The main circuit board is designed with universal connection interfaces that can accommodate multiple types of switch modules. The same connection mechanism (magnetic, snap-fit, or screw-based) supports different switch module variants, allowing a single main circuit board to work with multiple switch module types. This universality enables users to adapt the device to different preferences or applications without requiring custom manufacturing for each configuration.
3Device complexity
If switch modules are fixed on the main circuit board, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The switch modules are extracted as separate replaceable units with user-friendly attachment and detachment mechanisms. The connection interfaces are designed for easy operation, such as magnetic connectors that snap together with a simple pull motion or snap-fit mechanisms that require minimal force. This extraction improves ease of operation by allowing users to quickly replace switch modules without complex tools or procedures, while the overall device complexity remains manageable through standardized interfaces.
Solution Approach 2:
The switch module replacement mechanism is designed to be self-service friendly, requiring minimal technical knowledge or specialized tools. The connection interfaces are positioned for easy access, and the attachment/detachment mechanisms are intuitive (e.g., magnetic attraction that automatically aligns components). This self-service design enables users to perform maintenance and upgrades independently, improving ease of operation without significantly increasing device complexity.
