Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shielding layers are added to protect against electromagnetic fields, then electromagnetic compatibility is improved, but weight increases
Solution Approach 1:
The patent employs thin-film shielding layers deposited on circuit board surfaces instead of traditional bulky metallic enclosures. These thin films provide effective electromagnetic shielding while minimizing weight addition, directly resolving the contradiction between EMC protection and weight increase.
Solution Approach 2:
The patent uses composite structures combining dielectric materials with conductive coatings or layered composite boards (such as FR4 with copper traces or embedded shielding layers). These composite materials provide both structural support and electromagnetic shielding functionality, achieving effective protection with minimal weight penalty.
2Reliability
If multiple shielding layers are used to improve electromagnetic compatibility, then protection effectiveness increases, but device complexity increases
Solution Approach 1:
The patent integrates shielding functionality directly into the circuit board structure itself, merging the mechanical support function and electromagnetic shielding function into a single component. This eliminates the need for separate shielding enclosures or additional mounting hardware, reducing overall device complexity while maintaining multiple layers of protection.
Solution Approach 2:
The circuit board is designed to serve multiple functions simultaneously: electrical connection, mechanical support, and electromagnetic shielding. The same structural elements that provide mechanical integrity also provide electromagnetic protection, reducing the number of separate components needed and simplifying the overall device architecture.
