Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless data transfer between mobile terminal and display device is implemented, then physical connection requirement is eliminated, but data communication efficiency and intuitiveness deteriorate
Solution Approach 1:
The patent introduces proximity detection mechanisms (touch sensors, NFC tags, catadioptric cameras) as intermediaries to mediate the wireless data transfer process. These intermediaries detect the spatial relationship between devices and automatically initiate data transfer when proximity conditions are met, eliminating the need for manual connection establishment while maintaining high communication efficiency through context-aware automatic transfer
2Measurement precision
If proximity detection using multiple sensors is implemented, then data transfer accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple detection mechanisms (touch sensors, NFC tags, catadioptric cameras) into an integrated proximity detection system. These diverse sensors are merged to work together, with each sensor type contributing different aspects of proximity information, thereby achieving high detection accuracy while managing system complexity through coordinated multi-sensor operation
3Ease of operation
If automatic data transfer based on touch location is implemented, then user interaction intuitiveness is improved, but control complexity increases
Solution Approach 1:
The system implements self-service control by automatically determining data transfer parameters based on detected touch location and device orientation. The control system autonomously selects source and destination data elements without requiring explicit user commands, thereby enhancing interaction intuitiveness while managing control complexity through rule-based automatic decision-making
