Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a grounding plate with shielding plate and clips is used, then the shielding effect is improved, but the device complexity increases
Solution Approach 1:
The grounding plate integrates multiple functions: it provides grounding connection, supports shielding plates, and incorporates clips for securing terminals. By merging these functions into a single component, the design achieves effective shielding while reducing the number of separate parts needed.
Solution Approach 2:
The grounding plate serves multiple purposes simultaneously: electrical grounding, mechanical support for shielding plates, and structural anchoring for clips. This multi-functionality resolves the contradiction by achieving comprehensive shielding效果 without proportionally increasing complexity.
2Object-affected harmful factors
If plating process is used for shielding, then the shielding effect is achieved, but the manufacturing cost increases
Solution Approach 1:
The design uses simple metal grounding plates and shielding plates that can be manufactured through conventional forming processes rather than expensive plating. These components provide effective shielding through their geometric configuration and electrical connectivity rather than relying on plated surfaces.
Solution Approach 2:
The invention replaces the chemical plating process with a mechanical/electrical solution using conductive metal plates and clips. The shielding effect is achieved through the physical configuration and electrical connectivity of the grounding system rather than through plated coatings.
3Object-affected harmful factors
If plating process is used for shielding, then the shielding effect is achieved, but the manufacturing time increases
Solution Approach 1:
The design eliminates time-consuming plating processes by using simple formed metal components. The grounding plates and shielding plates can be manufactured through rapid forming processes, significantly reducing manufacturing cycle time while maintaining effective shielding performance.
