Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image sensing unit is pivotally supported to allow observation from both sides, then the device allows monitoring from front and rear surfaces, but the operation becomes cumbersome and the structure becomes complex
Solution Approach 1:
The liquid crystal display device is designed to dynamically change its light transmission characteristics based on the imaging direction. When the imaging lens faces the front surface, the display device transmits light for front observation; when the imaging lens faces the rear surface, the display device reflects light for rear observation. This dynamic adaptation eliminates the need for manual pivoting operations while maintaining the ability to observe from both sides.
Solution Approach 2:
The display device changes its optical parameters (transmission/reflection state) according to the imaging direction. By controlling the light transmission parameter of the liquid crystal display, the system automatically adapts to different observation requirements without mechanical movement, thereby improving ease of operation while preserving versatility.
2Adaptability or versatility
If the image sensing unit is pivotally supported to allow observation from both sides, then the device allows monitoring from front and rear surfaces, but the structure becomes complex
Solution Approach 1:
The display device and imaging unit are merged into a single integrated structure. The liquid crystal display device serves dual purposes: as the display medium and as the structural element that enables bidirectional observation. By combining these functions into one component rather than using separate pivoting mechanisms, the overall device complexity is reduced while maintaining the ability to observe from both front and rear surfaces.
Solution Approach 2:
The liquid crystal display device performs multiple functions: it displays images, controls light transmission, and enables bidirectional observation capability. This multi-functional design eliminates the need for separate mechanical pivoting structures, thereby simplifying the overall device structure while achieving the same versatility in observation capabilities.
3Reliability
If separate monitor image display device and electronic image sensing means are used independently, then the device achieves dedicated functions, but the manufacturing cost increases
