Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both touch input and pressure input are used to control electronic device operations, then the functionality and service expansion are improved, but the user difficulty in delivering intended input increases
Solution Approach 1:
The system dynamically adjusts its behavior based on the rate of pressure change. By detecting whether pressure changes rapidly or slowly, the device automatically determines the user's intended operation, eliminating the need for users to learn different input methods. This dynamic adaptation resolves the contradiction by making the system versatile in handling different input scenarios while maintaining ease of operation through automatic interpretation.
2Ease of operation
If pressure variation is sensed and used for control, then the intuitive user experience is improved, but the device complexity increases
Solution Approach 1:
The invention utilizes changes in the parameter of pressure over time (pressure change rate) to determine user intent. By monitoring how pressure varies temporally rather than just static pressure values, the system achieves more intuitive control. This approach enhances user experience while managing device complexity by focusing on temporal parameter analysis rather than adding multiple separate sensing mechanisms.
