Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the foldable housing uses multiple housings connected by hinge assemblies with different hinge angles, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The foldable housing is divided into multiple separate housings (first housing, second housing, third housing) connected by hinge assemblies. This segmentation allows each housing to be independently positioned and folded, improving ease of handling and storage while distributing the structural complexity across modular components rather than a single complex structure.
Solution Approach 2:
The hinge assemblies enable dynamic folding and unfolding operations, allowing the housing configuration to change from a flat unfolded state to a compact folded state. The different hinge angles (first angle range smaller than second angle range) provide optimized folding mechanics for each joint, enhancing operational ease while the dynamic adaptability reduces the need for overly complex fixed structures.
2Adaptability or versatility
If the flexible display is deformed through rotation of hinge plates, then the adaptability is improved, but the reliability deteriorates
Solution Approach 1:
The display uses a flexible display structure that can be deformed through rotation of hinge plates. The flexible display includes deformable areas that can be at least partially curved by rotation of hinge plates, allowing the display to adapt to different housing configurations (unfolded, folded, partially folded) while maintaining functionality across various shapes and orientations.
Solution Approach 2:
The hinge assemblies are designed with specific angle ranges where the first angle range is smaller than the second angle range. This pre-engineered angular constraint provides controlled deformation paths that prevent excessive bending stresses on the flexible display, thereby cushioning against potential damage and improving durability while still allowing adequate flexibility for folding operations.
3Ease of operation
If the first angle range is smaller than the second angle range, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The hinge assemblies are designed with different angle ranges optimized for their specific functions. The first hinge assembly has a smaller first angle range optimized for its folding operation, while the second hinge assembly has a larger second angle range suited for its operation. These parameter changes are built into the hinge design itself through geometric constraints and mechanical stops, allowing precise angle control to be achieved through design rather than requiring extremely tight manufacturing tolerances during assembly.
