Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate coupling members are used to join the main frame and inner plate, then the coupling strength is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The coupling function is merged into the inner plate itself by forming protrusions directly on the inner plate that insert into corresponding holes in the main frame. This eliminates the need for separate coupling members while maintaining coupling strength between the display panel assembly and the main frame.
Solution Approach 2:
The inner plate serves dual functions: it provides structural support for the display panel and simultaneously acts as the coupling mechanism through its integrated protrusions. The inner plate self-couples to the main frame without requiring external coupling components.
2Reliability
If multiple separate components are used for coupling, then the coupling reliability is improved, but the manufacturing cost and assembly process complexity increase
Solution Approach 1:
Multiple functions (structural support, positioning, and coupling) are merged into a single inner plate component. The protrusions are formed as integral parts of the inner plate through molding or other forming processes, eliminating the need for separate coupling components and reducing manufacturing steps.
Solution Approach 2:
The inner plate is designed as a multi-functional component that simultaneously provides mechanical support for the display panel, positional alignment through protrusions, and secure coupling to the main frame. This universal component replaces multiple specialized parts.
3Ease of operation
If traditional coupling structures are used, then the assembly process is straightforward, but the device thickness cannot be reduced
Solution Approach 1:
The protrusions of the inner plate are inserted into holes of the main frame in a nested arrangement, where the coupling structure is contained within the thickness of the assembly rather than adding external bulk. This nested coupling enables thin-profile construction while maintaining assembly simplicity.
4Stability of the object's composition
If separate coupling members are employed, then the structural stability is improved, but the manufacturing yield decreases due to more components
Solution Approach 1:
The coupling structure is merged into the inner plate as an integral feature rather than a separate component. This reduces the total number of parts that need to be manufactured, stored, and assembled, thereby improving manufacturing yield while maintaining structural stability through the designed protrusion-hole coupling geometry.
