Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the conductive member is fixed on the second surface of the substrate to shield electromagnetic noise during inspection, then electromagnetic shielding performance is improved, but the substrate may break when external circuits are replaced due to pressure treatment and heat treatment
Solution Approach 1:
The conductive member is extracted from the region opposite the connection terminal portions, creating a localized exclusion zone where the conductive member is not fixed. This allows the substrate to maintain flexibility in the connection region while preserving electromagnetic shielding in other areas.
Solution Approach 2:
The conductive member is arranged to cover specific regions on the second surface while intentionally excluding the region opposite the connection terminal portions. This creates non-uniform local properties where electromagnetic shielding is provided in some areas but not in the connection region, optimizing both shielding and mechanical flexibility.
2Object-affected harmful factors
If the conductive member is fixed on the second surface of the substrate, then electromagnetic shielding performance is improved, but inspection and replacement of external circuits becomes difficult requiring re-mounting
Solution Approach 1:
The conductive member is extracted from the region opposite the connection terminal portions, creating a clear access zone that allows external circuits to be connected and disconnected without interfering with the conductive member, eliminating the need for re-mounting during repairs.
Solution Approach 2:
The conductive member is selectively positioned to provide electromagnetic shielding in most areas while leaving the connection region exposed, enabling easy access for circuit inspection and replacement while maintaining shielding effectiveness elsewhere.
3Object-affected harmful factors
If the conductive member is fixed on the second surface of the substrate, then electromagnetic shielding performance is improved, but connection terminal portions may be affected by electromagnetic noise from the second surface side
Solution Approach 1:
The conductive member is extracted from the region opposite the connection terminal portions, eliminating the source of electromagnetic noise interference in the immediate vicinity of the connection terminals, thereby improving connection reliability.
Solution Approach 2:
The conductive member is positioned to provide electromagnetic shielding in regions away from the connection terminals while intentionally creating an electromagnetic noise-free zone around the connection terminal portions, optimizing both overall shielding and local connection reliability.
