Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch panel is added on top of the three-dimensional grating to integrate touch function, then the device can realize both touch and three-dimensional display functions, but the assembly structure becomes complex and requires high alignment precision
Solution Approach 1:
The patent merges the touch panel and three-dimensional grating into a single integrated structure where the same electrode layers serve both touch sensing and three-dimensional display functions. The first and second strip electrodes on opposing substrates form both the touch electrode structure and the three-dimensional grating structure, eliminating the need for separate components and reducing assembly complexity.
Solution Approach 2:
The electrode structures in the patent perform multiple functions: they serve as both touch driving/sensing electrodes and three-dimensional display driving electrodes. The same physical structures are utilized for both touch input and three-dimensional image display, allowing one component to fulfill multiple roles and simplifying the overall device architecture.
2Adaptability or versatility
If a touch panel is added on top of the three-dimensional grating, then touch function is achieved, but manufacturing cost increases due to complex structure and high alignment precision requirements
Solution Approach 1:
The patent combines touch panel manufacturing with three-dimensional grating manufacturing into a single integrated process. By using the same electrode layers and substrate structures for both functions, the patent eliminates the need for separate manufacturing steps and alignment procedures, thereby reducing manufacturing cost and complexity.
Solution Approach 2:
The same electrode structures are manufactured to serve dual purposes as both touch sensing elements and three-dimensional display elements. This multi-functionality approach allows a single manufacturing process to produce components that perform multiple functions, reducing the need for additional manufacturing steps and lowering overall production cost.
3Adaptability or versatility
If a touch panel is added on top of the three-dimensional grating, then touch function is achieved, but the thickness of the display device is greatly increased
Solution Approach 1:
The patent merges the touch panel and three-dimensional grating into a single integrated structure where both functions are realized within the same physical space and thickness envelope. By eliminating the need for a separate touch panel layer, the patent significantly reduces the overall device thickness while maintaining both touch and three-dimensional display capabilities.
Solution Approach 2:
The electrode structures perform multiple functions within the same physical space, serving as both touch sensing elements and three-dimensional display elements. This multi-functionality allows the device to achieve touch capability without adding the extra thickness that would result from stacking a separate touch panel on top of the three-dimensional grating.
