Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If motion detectors are used to detect authentication targets, then detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces motion detectors (mechanical/electronic detection devices) with image processing technology that analyzes light emitting areas in captured images. This substitution maintains detection capability while eliminating the need for specialized detection hardware, thereby reducing device complexity and cost.
Solution Approach 2:
The patent uses image capture to create a visual copy of the scene, then processes this copy to detect light emitting areas and authenticate targets. This approach avoids direct use of motion detectors by working with image data instead, simplifying the overall system architecture.
2Reliability
If authentication processing is continuously performed, then authentication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic authentication processing triggered by detection of light emitting areas in images, rather than continuous processing. The system captures images, detects light emitting areas, and only performs authentication when relevant patterns are found, thereby maintaining reliability while significantly reducing power consumption during idle periods.
Solution Approach 2:
The patent dynamically adjusts the authentication processing frequency based on environmental conditions. When light emitting areas are detected in captured images, authentication is triggered; otherwise, the system enters a lower-power state. This dynamic approach balances reliability requirements with power conservation.
