Engineering Contradiction Analysis
1Measurement precision
If fixed threshold values are used for proximity detection, then the system structure remains simple, but detection precision deteriorates due to environmental variations and different grip strengths
Solution Approach 1:
The patent implements dynamic threshold adjustment by continuously monitoring physical parameters (temperature, humidity, pressure) and automatically updating the proximity detection threshold based on environmental conditions and grip strength variations. This transforms the static threshold into a dynamic value that adapts to changing conditions, resolving the contradiction between maintaining simple structure and achieving high detection precision.
Solution Approach 2:
The system changes the threshold parameter based on detected physical conditions. By monitoring environmental parameters and grip-related parameters, the system adjusts the threshold value to compensate for variations, thereby maintaining high detection precision without requiring complex manual calibration mechanisms.
2Measurement precision
If dynamic threshold adjustment based on physical parameters is implemented, then proximity detection precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the hand-held controller perform multiple functions: proximity detection, environmental sensing (temperature, humidity, pressure), and grip strength detection. By integrating these diverse sensing capabilities into a single device, the system achieves high detection precision without proportionally increasing overall device complexity, as the additional sensors share the same processing infrastructure.
Solution Approach 2:
The system implements feedback loops where physical parameter measurements continuously inform threshold adjustments. The processed data from environmental and grip sensors feeds back to dynamically modify the proximity detection threshold, creating a self-regulating system that maintains precision while using standard feedback control mechanisms rather than complex proprietary algorithms.
3Reliability
If multiple sensors and processing operations are added for dynamic threshold adjustment, then detection reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic sampling of physical parameters rather than continuous monitoring. The system updates the proximity threshold at specific intervals or when significant environmental changes are detected, reducing energy consumption while maintaining detection reliability. This periodic action allows the multiple sensors to be used efficiently without constant power consumption.
