Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a light conversion unit is introduced into the electronic device, then light conversion properties are improved, but device structure becomes more complex
Solution Approach 1:
The patent applies porous materials by forming a porous structure within the light conversion unit that contains multiple pores of different sizes. This porous structure allows light to interact with light conversion materials distributed throughout the pores, significantly improving light conversion properties while maintaining a compact integrated structure that does not substantially increase device complexity
Solution Approach 2:
The patent employs composite materials by combining light conversion materials with a porous matrix structure. The composite light conversion unit integrates multiple functional components (light conversion materials, porous structure, binding agents) into a single unit that achieves improved light conversion performance without requiring separate discrete components, thus avoiding substantial increases in device structural complexity
2Reliability
If a porous structure with irregularly arranged pores is used, then light conversion properties are enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies preliminary action by forming the porous structure and distributing light conversion materials within the pores before final device assembly. The porous structure is created in advance with its irregular pore arrangement, and light conversion materials are incorporated during this preliminary formation stage, simplifying the overall manufacturing process while achieving enhanced light conversion properties
Solution Approach 2:
The patent employs parameter changes by controlling the physical and chemical parameters during porous structure formation to create irregular pores with optimized size distributions. By adjusting parameters such as porosity, pore size distribution, and material composition during manufacturing, the process achieves enhanced light conversion properties without requiring extreme manufacturing precision for individual pore positions
