Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a liquid crystal display device uses a plastic substrate to reduce weight, then the weight is reduced, but the device lacks versatility in shape and application
Solution Approach 1:
The patent applies the dynamics principle by making the substrate flexible rather than rigid, allowing it to adapt to various shapes and applications. The flexible substrate can be bent, curved, or folded to match different form factors while maintaining structural integrity, thus achieving both weight reduction and shape versatility.
Solution Approach 2:
The patent changes the physical parameters of the substrate by using flexible materials with appropriate mechanical properties. By selecting substrates with specific flexibility, tensile strength, and thermal expansion characteristics, the device achieves both lightweight construction and adaptability to various shapes without complicating the manufacturing process.
2Adaptability or versatility
If the liquid crystal display device is shaped after the manufacture of electrode and element layers, then the device gains useful function, but the manufacturing process becomes complicated
Solution Approach 1:
The patent applies preliminary action by pre-forming the substrate into the desired shape before manufacturing the electrode and element layers. This allows the display device to gain its useful function and customized shape without requiring complex post-processing steps, as the shaping is already accomplished in the substrate preparation stage.
3Adaptability or versatility
If various kinds of liquid crystal display devices are manufactured by selecting mold shape, then versatility is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies universality by using a standardized flexible substrate that can be manufactured once and then adapted to various shapes using different molds. This single substrate design serves multiple functions across different applications, allowing versatility to be improved while keeping the base manufacturing process simple and unchanged.
