Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive plastic blocks are used to shield signal terminals, then electrical performance and transmission rate are improved, but loosening phenomenon occurs between the conductive plastic block and the insulative housing
Solution Approach 1:
A conductive adhesive layer is introduced as an intermediary between the conductive plastic blocks and the insulative housing. This adhesive layer prevents loosening while maintaining the shielding function of the conductive blocks, thus resolving the contradiction between electrical performance and structural stability.
Solution Approach 2:
The physical and chemical parameters of the adhesive layer are optimized to achieve both strong bonding strength and appropriate electrical conductivity. By controlling the thickness, composition, and curing characteristics of the adhesive, the system maintains electrical performance while preventing loosening between components.
2Productivity
If conductive plastic blocks are used to reduce signal interference, then transmission rate is enhanced, but loosening phenomenon occurs during practical use
Solution Approach 1:
The conductive adhesive serves as a mediator that secures the conductive plastic blocks to the insulative housing, preventing loosening during use. This ensures the shielding structure remains intact to maintain high transmission rates without degradation from mechanical instability.
Solution Approach 2:
The system uses a composite structure combining the insulative housing, conductive plastic blocks, and conductive adhesive layer. This multi-material approach allows each component to perform its specific function while working together to prevent loosening and maintain high-frequency transmission performance.
3Reliability
If grounding terminals are shorted using cured conductive adhesive, then high-frequency transmission performance is improved, but additional manufacturing steps are required
Solution Approach 1:
The conductive adhesive simultaneously performs multiple functions: it bonds the conductive plastic blocks to the housing and shorts the grounding terminals. By merging these two functions into a single material application, the manufacturing process is simplified despite the added functionality.
Solution Approach 2:
The conductive adhesive is designed with multi-functionality, serving as both a bonding agent and an electrical conductor for grounding. This universal application reduces the need for separate components or steps, improving high-frequency performance while maintaining reasonable manufacturing ease.
