Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display devices function as touchscreens with two-dimensional surfaces, then they are simple and easy to manufacture, but their applications are limited and lack texture for enhanced input/output functions
Solution Approach 1:
The patent applies dimensionality change by transitioning from a two-dimensional flat display surface to a three-dimensional surface with varying heights, indentations, and textures. This is achieved through electroactive polymers and piezoelectric materials that create tactilely distinct regions, enabling enhanced input/output functions while maintaining manufacturing feasibility through integrated material layers.
2Ease of operation
If the display surface is made flat and smooth, then manufacturing is easier, but tactile sensations and texture are lost
Solution Approach 1:
The patent employs composite materials by integrating electroactive polymers, piezoelectric materials, and organic transistors into the display structure. These composite materials enable the surface to dynamically change its tactile properties, providing textured regions for enhanced operation while maintaining compatibility with standard manufacturing processes through layered construction.
3Adaptability or versatility
If elevated and texturized structures are added to the display, then input/output capabilities are enhanced, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a unified display structure by combining electroactive polymers, piezoelectric materials, and organic transistors within the same device architecture. This integration allows the display to simultaneously provide visual output and tactile feedback, enhancing input/output capabilities without requiring separate components for each function.
