Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional rigid display devices are used, then manufacturing and structural stability are improved, but the ability to conform to three-dimensional surfaces and dynamic shape change is lost
Solution Approach 1:
The display device employs dynamic elements including a deformable substrate, stretchable electrode layers, and a stretchable display medium layer that can dynamically change shape in response to applied forces or voltages. This allows the rigid display structure to transform into a flexible, three-dimensional conforming configuration, resolving the contradiction between structural stability and adaptability to complex surfaces.
Solution Approach 2:
The patent utilizes parameter changes in the physical state of the display components, particularly through voltage application to the electrophoretic display medium and stretchable electrodes. These parameter changes enable the display to transition between different shapes and conformations while maintaining functional integrity, allowing adaptation to three-dimensional surfaces without permanent structural compromise.
2Adaptability or versatility
If a stretchable electrophoretic display medium is used to achieve three-dimensional shaping, then adaptability to complex surfaces is improved, but device complexity increases
Solution Approach 1:
The patent employs flexible thin film structures including a deformable substrate and stretchable electrode layers that can be deposited as thin, flexible coatings. These thin film structures provide the necessary flexibility for three-dimensional shaping while maintaining a relatively simple overall device architecture, avoiding the need for complex mechanical actuation systems.
Solution Approach 2:
The display device utilizes composite material structures combining deformable substrates, stretchable electrodes, and electrophoretic display media. These composite materials integrate multiple functions (structural support, electrical conductivity, display functionality) into unified layers, reducing the number of separate components and simplifying the overall device complexity while enabling three-dimensional shaping.
