Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UWB module is used for distance and angle measurement, then measurement precision is improved, but user privacy is leaked
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the measurement precision parameters of the UWB module. The system changes the distance measurement precision from centimeter-level to meter-level based on privacy settings, and adjusts angle measurement precision similarly. This allows the system to maintain measurement functionality while controlling the precision level to prevent accurate location tracking.
Solution Approach 2:
The patent implements dynamics by making the measurement precision adjustable and changeable in real-time. The system dynamically modifies the precision parameters according to user preferences and privacy requirements, allowing the measurement capability to adapt between high precision (when needed) and low precision (when privacy is concerned), rather than being fixed.
2Adaptability or versatility
If UWB detection is enabled for social functions, then social requirements are met, but device safety is compromised
Solution Approach 1:
The patent applies dynamics by enabling the UWB detection function to be dynamically controlled through privacy settings. The system can switch between enabled and disabled states, and adjust detection ranges, allowing the social functions to be adaptable while maintaining safety control through user-defined parameters.
Solution Approach 2:
The patent applies local quality by implementing different privacy protection levels for different detection scenarios. The system allows selective enabling of detection functions for specific social applications while maintaining stricter controls for other uses, creating localized privacy protection strategies for different functional areas.
3Measurement precision
If precise location information is obtained through multiple UWB modules, then positioning accuracy is improved, but privacy leakage increases
Solution Approach 1:
The patent applies parameter changes by modifying the measurement precision parameters of participating UWB modules. When privacy protection is activated, the system changes the distance and angle measurement precision parameters to lower values, which directly reduces the positioning accuracy that can be achieved, thereby preventing precise location tracking while maintaining functional operation.
