Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple vibration motors are disposed in different housings to provide spatially distributed feedback, then user convenience and interaction quality are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The vibration feedback system is segmented into multiple independent vibration motors disposed in different housings (first housing and second housing). Each motor can be controlled independently to provide spatially distributed haptic feedback, improving user interaction quality by enabling differentiated tactile responses in different regions of the device.
2Measurement precision
If multiple sensors are used to detect both folding state and grip state, then state identification accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The sensing system is segmented into two functional groups: first sensors for detecting folding state and second sensors for detecting grip state. This segmentation allows each sensor type to be optimized for its specific detection task, improving overall measurement precision while maintaining manageable system complexity through functional separation.
Solution Approach 2:
The sensor system is designed with multi-functionality where the same sensor infrastructure can potentially serve multiple detection purposes. The processor integrates signals from both first and second sensors to simultaneously determine folding state and grip state, making the sensing system universally applicable to multiple state detection requirements.
3Productivity
If vibration motors are controlled based on integrated folding and grip state detection, then operational efficiency is improved, but processing complexity increases
Solution Approach 1:
The processor performs preliminary processing by separately detecting folding state and grip state using dedicated sensors before integrating this information to control vibration motors. This preliminary action allows for efficient state determination and enables the vibration motors to be activated only when both conditions are met, improving operational efficiency through pre-filtering of control signals.
