Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional press molding apparatus is used to manufacture a fixing frame, then the manufacturing process is simple, but the depth of curvature is limited to a predetermined size
Solution Approach 1:
The fixing frame is divided into multiple separate fixing frames that can be manufactured within the stroke limits of conventional press molding apparatuses. These segmented frames are then assembled together using connecting units to form a complete fixing frame with the desired large depth of curvature, thereby resolving the contradiction between manufacturing simplicity and curvature depth capability.
2Area of moving object
If the size of curved display devices is increased, then the screen size is larger, but the viewing angle difference increases
Solution Approach 1:
The fixing frame is designed with a curved configuration that corresponds to the desired curvature of the display panel. This curvature allows large display devices to maintain uniform viewing angles across the screen by ensuring that pixels at different positions (center and edges) are oriented correctly relative to the viewer, thus resolving the viewing angle difference problem while maintaining large screen size.
3Shape
If a fixing frame with large depth of curvature is manufactured, then the desired curvature is achieved, but conventional press molding apparatuses cannot produce it due to stroke limitations
Solution Approach 1:
Instead of manufacturing a single large-curved fixing frame that would require apparatus modification, the invention segments the fixing frame into multiple smaller sections that can be produced by conventional press molding apparatuses within their stroke limitations. These segments are then assembled to achieve the overall large depth of curvature without modifying existing equipment.
Solution Approach 2:
The solution transitions from a single-dimension approach (one large curved frame) to a multi-dimensional approach by introducing the assembly dimension. Multiple planar or mildly curved segments are arranged and connected in space to form the final large-curved structure, effectively achieving the desired curvature through spatial arrangement rather than single-step molding.
4Strength
If the fixing frame is made stronger to support larger curved display devices, then structural integrity is improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple fixing frame segments are merged together through connecting units to form a complete fixing frame structure. This combined structure distributes mechanical loads across multiple components and connection points, achieving the required structural integrity for supporting large curved display devices while maintaining manufacturability through modular assembly rather than requiring a single complex monolithic structure.
