Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current vibration modules are used, then the device can provide basic vibration notification, but the vibration feedback cannot be effectively transmitted to the button
Solution Approach 1:
The haptic feedback system is nested within the electronic component housing, with the driving assembly, movable part, and circuit assembly all integrated into a compact layered structure. The movable part is positioned between the driving assembly and the button, creating a nested arrangement that maximizes space utilization while ensuring effective vibration transmission through the button.
Solution Approach 2:
The movable part serves as an intermediary element between the driving assembly and the button. It receives driving forces from the driving assembly and transmits them to the button, ensuring effective vibration feedback. This intermediary structure allows for optimized force transmission while maintaining structural integrity.
2Reliability
If the movable part is driven to move relative to the fixed assembly, then feedback force is generated, but the circuit connections become complex
Solution Approach 1:
The circuit assembly merges multiple circuit elements into a single integrated structure that accommodates all necessary electrical connections. The first, second, third, fourth, and fifth circuit elements are combined in a way that simplifies the overall circuit layout while maintaining all required connections between the driving assembly, movable part, and external circuits.
Solution Approach 2:
The circuit assembly is designed with multi-functional circuit elements that can handle multiple electrical connections and signal types. The circuit elements are configured to accommodate both the driving signals to the movable part and the feedback signals from the button, reducing the overall complexity by using universal connection structures.
