Engineering Contradiction Analysis
1Shape
If a flat display panel is used, then the external shape requirement is satisfied, but the volume and weight increase
Solution Approach 1:
The patent applies curvature to the display panel and base structure, transforming the traditional flat geometry into a curved configuration. The display panel is mounted on a curved base with stepwise plane surfaces, allowing the external shape to be non-flat while maintaining structural integrity and functional requirements.
2Shape
If a flat display panel is used, then the external shape requirement is satisfied, but the weight increases
Solution Approach 1:
The curved base structure with stepwise plane surfaces replaces the traditional flat base, reducing material usage and overall weight while satisfying external shape requirements. The curved geometry allows for more efficient space utilization and reduced structural mass.
3Volume of moving object
If a curved display panel is used, then the volume is reduced, but the driver circuit mounting becomes complex
Solution Approach 1:
The base structure is divided into multiple stepwise plane surfaces at different heights, creating segmented mounting regions for driver circuits. This segmentation allows circuits to be mounted on flat surfaces while the overall base maintains a curved configuration, simplifying the mounting process.
Solution Approach 2:
The patent introduces vertical dimensionality through stepwise plane surfaces at different heights, transforming a two-dimensional flat mounting surface into a three-dimensional stepped structure. This allows driver circuits to be mounted on multiple levels, efficiently utilizing the reduced volume while maintaining mounting simplicity.
4Adaptability or versatility
If a curved display panel is used, then the design flexibility is improved, but the electrical connection becomes complex
Solution Approach 1:
The base is segmented into multiple stepwise plane surfaces, creating distinct regions for electrical connections. The display panel is electrically connected to the curved surface and to the driver circuits mounted on the stepwise plane surfaces through defined connection paths, simplifying the overall electrical connection structure.
