Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image capturing unit and image recognition unit are used for illumination control, then control accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential motion detection function from complex image recognition systems. Instead of using full image capturing and recognition units, it employs a simplified motion detector that specifically detects gestures, removing unnecessary components while maintaining control functionality.
Solution Approach 2:
The patent replaces complex mechanical/optical image recognition systems with a simpler motion detection mechanism. The motion detector uses sensor-based detection (such as infrared or capacitive sensing) to detect gestures, substituting the need for cameras and complex image processing algorithms.
2Device complexity
If motion detector is used for gesture detection, then device complexity is reduced, but control precision may deteriorate
Solution Approach 1:
The motion detector is designed to perform multiple functions: detecting presence, detecting gestures, and determining gesture intensity. This multi-functionality allows a simple component to achieve precise control by extracting different types of information from the same sensor input.
Solution Approach 2:
The system uses feedback from the motion detector to adjust illumination parameters. The detector continuously monitors gesture presence and intensity, providing real-time feedback that allows the control unit to precisely adjust illuminance, color temperature, and other parameters based on detected gesture patterns.
