Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional organic materials are used in deposition processes, then the organic electric element can be manufactured, but the driving voltage is high and luminous efficiency is low
Solution Approach 1:
The patent changes the physical parameters of the organic material by controlling its molecular weight distribution and crystallinity during the deposition process. By optimizing these parameters, the material achieves lower driving voltage and higher luminous efficiency while maintaining manufacturing feasibility
Solution Approach 2:
The patent employs composite organic materials with specific molecular weight distributions and crystalline structures. These composite materials are designed to optimize both the electrical properties (lower driving voltage) and optical properties (higher luminous efficiency) simultaneously
2Ease of manufacture
If organic materials with specific deposition characteristics are used, then manufacturing process is simplified, but gas generation and impurity exposure increase
Solution Approach 1:
The patent optimizes the molecular weight distribution and crystallinity parameters of the organic material to reduce gas generation during deposition. These parameter changes maintain ease of manufacture while minimizing harmful factors
Solution Approach 2:
The patent employs inert atmosphere techniques during the deposition process to minimize impurity exposure and gas generation from the organic material, thereby reducing harmful factors while maintaining manufacturing simplicity
3Productivity
If standard organic materials are deposited, then the element can be produced, but lifespan is reduced due to impurity exposure
Solution Approach 1:
