Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional manufacturing processes are used for night vision devices, then the device can achieve night vision function, but the manufacturing process becomes complex
Solution Approach 1:
The patent divides the optical amplifying module into three separate substrates: a light receiving substrate containing light receiving elements, a current amplifying substrate containing current amplifying elements, and a light emitting substrate containing light emitting elements. Each substrate is manufactured and tested independently, then assembled together. This segmentation simplifies the manufacturing process by allowing parallel production and reducing the complexity of handling a single integrated complex device.
2Reliability
If conventional manufacturing processes are used for night vision devices, then the device can achieve night vision function, but the production yield decreases
Solution Approach 1:
The patent implements preliminary testing of each substrate (light receiving substrate, current amplifying substrate, and light emitting substrate) before final assembly. Defective substrates are identified and replaced early in the process, preventing assembly of non-functional modules. This preliminary action ensures higher production yield by filtering out defective components before they are integrated into the final product.
