Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a large curvature changing structure is used, then the curvature can be implemented, but the device complexity and size increase
Solution Approach 1:
The curvature changing structure is divided into multiple curvature changing units, each comprising a pair of curvature implementation bars. This segmentation allows the large curvature implementation task to be distributed across multiple smaller, manageable units, reducing the complexity of each individual component while achieving the overall curvature effect.
Solution Approach 2:
The curvature implementation bars are designed with variable coupling units that can change their coupling positions on the back cover. This dynamic adjustment capability allows the bars to adapt to different curvature requirements by changing their attachment points, enabling curvature variation without requiring a completely different structural configuration.
2Adaptability or versatility
If a fixed curvature structure is used, then the structure is simple, but the curvature cannot be adjusted when necessary
Solution Approach 1:
The curvature implementation bars incorporate variable coupling units that can be coupled to the back cover at different positions. This dynamic coupling mechanism allows the structure to transition from a fixed configuration to an adjustable one, enabling curvature variation while maintaining relative structural simplicity through standardized coupling interfaces.
Solution Approach 2:
The curvature implementation bars serve multiple functions: they provide structural support, enable curvature implementation, and allow for adjustable curvature through variable coupling. This multi-functionality reduces the need for separate adjustment mechanisms, thereby limiting the increase in overall structural complexity while achieving adaptability.
3Adaptability or versatility
If the curvature implementation bars are coupled at fixed locations, then the coupling is stable, but the curvature cannot be changed
Solution Approach 1:
The variable coupling units are designed to maintain stable coupling at each selected position while allowing repositioning to different locations. The coupling mechanism provides firm attachment when positioned, ensuring reliability, while the ability to change positions enables curvature variation. This dynamic positioning capability reconciles the conflict between coupling stability and curvature adaptability.
4Ease of operation
If a simplified curvature structure is used, then the device can be transferred readily, but the coupling between back cover and components may deviate
Solution Approach 1:
The curvature structure is divided into modular curvature changing units with standardized coupling interfaces. This segmentation and standardization allow the units to be easily assembled and disassembled for transfer, while the standardized interfaces ensure proper alignment and coupling stability, preventing deviation during reassembly after transfer.
