Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional metal cover is added to achieve shielding, then shielding effect is improved, but manufacturing precision and structural integrity deteriorate
Solution Approach 1:
The bridging piece is divided into two distinct parts: a connector portion for electrical connection and an insulative insert portion for structural support. This segmentation allows each part to optimize its specific function - the connector provides precise electrical contact while the insulative insert maintains structural integrity and positioning accuracy, resolving the contradiction between shielding effectiveness and manufacturing precision.
Solution Approach 2:
The bridging piece combines conductive materials (for electrical connection) with insulative materials (for structural support) into a single integrated component. This composite structure enables simultaneous achievement of electrical connectivity for shielding and mechanical stability for manufacturing precision, eliminating the need for separate metal covers that compromise structural integrity.
2Object-affected harmful factors
If shielding cover is added to circuit board, then shielding effect is improved, but device complexity increases
Solution Approach 1:
The bridging piece merges multiple functions into a single component: electrical connection, structural support, insulation, and positioning. By combining the connector and insulative insert into one integrated piece that is inserted into a single hole, the design eliminates the need for separate shielding covers and multiple fastening elements, thereby reducing device complexity while maintaining effective shielding.
3Object-affected harmful factors
If conventional shielding technology is used, then shielding is achieved, but cooling effectiveness deteriorates
Solution Approach 1:
The insulative insert is positioned specifically at the second surface of the connector to provide localized insulation and structural support. This localized approach allows heat to be managed effectively - the connector provides electrical connection and heat conduction paths, while the insulative insert provides targeted thermal isolation where needed, enabling both shielding and effective cooling without the thermal blockage caused by conventional metal covers.
