Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are added to enhance functionality, then the device performance is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensors (non-contact sensor and optical sensor) into a single stationary device housing, integrating their functions rather than using separate devices. The controller receives and processes outputs from both sensors simultaneously, merging detection capabilities into one unified system that enhances functionality without requiring multiple separate devices.
Solution Approach 2:
The stationary device is designed with multi-functionality by incorporating both non-contact sensing (for presence detection) and optical sensing (for light level detection) capabilities within a single device. This universal design allows the device to perform multiple functions - detecting user presence, monitoring ambient light, and controlling display brightness - thereby improving adaptability while maintaining a consolidated device structure.
2Measurement precision
If sensors are positioned to optimize detection, then the detection accuracy is improved, but the device structure becomes more complex
Solution Approach 1:
The patent applies local quality by positioning sensors in specific locations optimized for their detection functions. The non-contact sensor is placed in the upper region where it can effectively detect presence, while the optical sensor is positioned in the lower region for optimal light level detection. Each sensor is located in the most favorable position for its specific detection task, improving measurement precision without requiring complex internal routing or positioning mechanisms.
