Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the conductive terminals are designed with separate mating portion, connection portion and tail portion extending along the mating direction, then the structural complexity is reduced, but the shielding effectiveness may be compromised
Solution Approach 1:
The conductive terminal is divided into three distinct portions: mating portion, connection portion, and tail portion, each serving specific functions. This segmentation simplifies the overall structure while maintaining functional integrity and enabling effective shielding design.
Solution Approach 2:
The metal shield encloses the conductive terminal, forming a nested structure where the terminal is positioned within the shielded cavity. This nesting arrangement provides effective electromagnetic shielding while maintaining a compact overall structure.
2Reliability
If metal shields with extension portions are added to enclose the conductive terminals, then the shielding effectiveness is improved, but the device complexity increases
Solution Approach 1:
The metal shield structure integrates multiple functions: the main body provides enclosure while the extension portions provide additional shielding and structural support. This merging of functions reduces the need for separate components and simplifies the overall assembly.
Solution Approach 2:
The metal shield serves multiple purposes: electromagnetic shielding, structural support, and positioning of conductive terminals. This multi-functionality reduces the total component count and simplifies the device structure while maintaining effective shielding.
