Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a photoelectric conversion unit is added to convert transmitting light into electrical energy, then energy saving is improved, but device complexity increases
Solution Approach 1:
The display layer is designed to perform multiple functions: it serves as both the light reflection/display medium and integrates the photoelectric conversion unit within its structure. The photoelectric conversion unit is embedded in the display layer, allowing it to simultaneously maintain display functionality while converting transmitting light into electrical energy, thus reducing overall device complexity despite adding energy harvesting capability
Solution Approach 2:
The photoelectric conversion unit is nested within the display layer structure. Specifically, the photoelectric conversion unit is positioned at a specific depth within the display layer, allowing it to be embedded without adding external components. This nesting approach enables the photoelectric conversion function to be integrated into the existing display structure, minimizing increases in device complexity while achieving energy saving
2Manufacturing precision
If multiple photoelectric conversion units with different wavelength absorption ranges are used, then color purity is improved, but device complexity increases
Solution Approach 1:
The photoelectric conversion functionality is segmented into multiple specialized units, each designed to absorb specific wavelength ranges. The display layer contains multiple photoelectric conversion units with different absorption characteristics (e.g., first photoelectric conversion unit for blue light, second for green light, third for red light), allowing each unit to optimize its performance for a specific color range, thereby improving overall color purity
Solution Approach 2:
Different regions of the display layer are assigned different photoelectric conversion units with specialized wavelength absorption properties. Each photoelectric conversion unit is positioned and configured to handle specific color wavelengths, creating local optimization for color purity. This local quality approach allows the system to achieve high color purity without requiring complete redesign of the entire device structure
