Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electronic components are placed in close proximity to improve integration, then device compactness is improved, but electromagnetic interference between components increases
Solution Approach 1:
The device is segmented into multiple isolated cavities within a single housing, with each cavity containing specific electronic components. The connector shield divides the internal space into distinct regions (first cavity for RF components, second cavity for power converter components), preventing electromagnetic interference while maintaining compact integration.
Solution Approach 2:
A connector shield acts as an intermediary structure between different electronic components. This shield with conductive gaskets serves as a mediator that allows electrical connection while blocking electromagnetic interference, enabling close proximity placement without interference.
2Object-affected harmful factors
If connector shields with gaskets are used to reduce EMI, then electromagnetic interference protection is improved, but device complexity increases
Solution Approach 1:
The connector shield integrates multiple functions into a single component: it provides structural support for mounting circuit boards, creates cavity divisions for EMI isolation, incorporates conductive gaskets for both electrical connection and sealing, and attaches to the housing as a unified assembly. This merging reduces the number of separate parts needed.
Solution Approach 2:
The connector shield serves multiple purposes simultaneously: it acts as a partition wall for EMI isolation, provides mounting surfaces for circuit boards, incorporates electrical connections through integrated gaskets, and seals the cavities. This multi-functionality reduces overall device complexity despite enhanced EMI protection.
