Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional materials are used in optoelectronic devices, then the device structure is simple, but the device cannot accurately recognize user information at low temperatures
Solution Approach 1:
The patent changes the chemical composition parameters of the optical activation layer by using specific compounds (first compound with Formula 1, second compound with Formula 2, and third compound with Formula 3) having particular molecular structures and energy levels. This parameter change enables the layer to maintain its optical activation functionality at low temperatures, resolving the contradiction between recognition accuracy and temperature limitation
Solution Approach 2:
The patent creates a composite material system by combining three different compounds in the optical activation layer, each with specific structural characteristics. The composite structure allows the materials to work synergistically, maintaining effective optical activation at low temperatures while improving user information recognition accuracy
2Reliability
If materials requiring high deposition temperature are used, then the optical activation layer has good performance, but the manufacturing process becomes complex and costly
Solution Approach 1:
The patent modifies the deposition temperature parameter by selecting compounds with specific molecular structures (Formulas 1, 2, and 3) that have appropriate volatility and bonding characteristics. These parameter changes enable deposition at lower temperatures while maintaining the reliability and performance of the optical activation layer
3Measurement precision
If the optical activation layer uses complex material composition, then user information recognition accuracy improves, but the device complexity increases
Solution Approach 1:
The patent applies local quality by optimizing the material composition specifically in the optical activation layer while keeping other device components relatively simple. The layer uses a targeted combination of three compounds with specific formulas, providing high recognition accuracy without requiring complex materials throughout the entire device structure
