Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile micro-Doppler antennas are used in head-worn computing devices, then spatial location presentation and environmental awareness capabilities are enhanced, but antenna position stability deteriorates due to head movement
Solution Approach 1:
The system employs feedback mechanisms where sensors detect head position and movement, and this information is used to dynamically adjust antenna positioning or signal processing parameters to compensate for movement and maintain stable spatial location presentations
Solution Approach 2:
Mechanical gyroscopes and position correction systems act as intermediaries between the moving antenna and the signal processing system, measuring and compensating for positional changes to maintain signal stability
2Stability of the object's composition
If mechanical gyroscopes and position correction systems are implemented, then antenna position stability is improved, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical stabilization mechanisms with software-based signal processing and computational methods that can compensate for antenna movement through digital signal processing and position correction algorithms
Solution Approach 2:
The system dynamically adjusts signal processing parameters such as frequency compensation, phase correction, and gain settings based on detected head position and movement characteristics to maintain stable antenna performance
3Measurement precision
If antenna position is stabilized during signal acquisition, then target tracking accuracy is improved, but response time increases due to correction processing
Solution Approach 1:
The system performs preliminary calibration and establishes baseline position data before signal acquisition begins, allowing for faster real-time corrections during actual target tracking without requiring extensive processing during critical measurement phases
Solution Approach 2:
The system uses predictive algorithms that estimate antenna position based on previous movement patterns, allowing it to skip detailed correction calculations for predictable movements and only perform full corrections when significant position changes occur
