Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mirror display reflects light from external light sources to perform mirror function, then the mirror function is achieved, but the visibility of displayed content is degraded
Solution Approach 1:
The display area is segmented into a first area for user reflection and a second area for content display. The processor determines these areas separately and controls luminance independently for each area, allowing the mirror function and content display to coexist without mutual interference.
Solution Approach 2:
Different luminance settings are applied to different areas of the mirror display. The second area displaying content has adjusted luminance based on incident light conditions, while the first area maintains mirror reflection properties. This local differentiation resolves the contradiction between mirror function and content visibility.
2Loss of information
If the display area is increased to show more content, then the information provision is improved, but the user reflection area is reduced
Solution Approach 1:
The mirror display surface is divided into distinct first and second areas. The first area preserves user reflection while the second area displays content. This segmentation allows both functions to operate simultaneously without one encroaching on the other's space.
Solution Approach 2:
The solution transitions from a single-dimensional area allocation problem to a two-dimensional spatial arrangement where user reflection and content display occupy different regions of the same surface, effectively resolving the area conflict through spatial differentiation.
3Illumination intensity
If the luminance of the display area is increased to improve visibility, then the content visibility is improved, but the energy consumption increases
Solution Approach 1:
The luminance of the second area is dynamically adjusted based on the intensity of incident light detected by the sensor. When external light is strong, luminance is reduced; when external light is weak, luminance is increased. This dynamic adaptation maintains content visibility while optimizing energy consumption.
Solution Approach 2:
A feedback mechanism is implemented where the sensor continuously monitors incident light intensity and provides information to the processor, which then adjusts the luminance of the display area accordingly. This closed-loop control ensures energy-efficient operation while maintaining adequate content visibility.
