Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a camera-based measurement device is used to specify measurement-related information, then the system can acquire and display related information (such as environmental temperature), but the system complexity increases due to the need for correspondence relationship storage and image analysis processing
Solution Approach 1:
The patent uses a camera to capture an image of the display light source, creating an optical copy of the light pattern. This copy is then analyzed to identify the display light characteristics, which correspond to measurement-related information. This copying approach enables information specification without requiring direct contact with the light source or complex sensing mechanisms.
Solution Approach 2:
The patent introduces an intermediary correspondence relationship storage that links display light characteristics to measurement-related information. This intermediary database enables the system to translate camera images of display light into meaningful measurement data, bridging the gap between simple optical capture and informative output without requiring complex direct measurement mechanisms.
2Ease of operation
If display light is continuously emitted to show measurement information, then the information is always visible, but the light source wears out faster
Solution Approach 1:
The patent implements periodic emission of display light rather than continuous emission. The light source is activated only when measurement-related information needs to be displayed, and the emission duration is controlled based on the specific information display requirements. This periodic action maintains information visibility while significantly reducing light source wear and extending its operational lifespan.
Solution Approach 2:
The patent makes the light emission dynamic by adjusting emission characteristics (on/off timing, duration, intensity) based on operational needs. The system can dynamically control when the light source is active and for how long, optimizing the balance between information visibility and light source preservation. This dynamic control allows the system to adapt light emission to actual usage requirements rather than operating continuously.
