Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the receiving chamber extends parallel to the circuit board, then the connector assembly occupies less vertical space, but the occupied area on the circuit board increases
Solution Approach 1:
The receiving chamber is configured to extend along a direction perpendicular to the circuit board, changing the spatial orientation from horizontal (parallel to circuit board) to vertical (perpendicular to circuit board). This dimensional reorientation reduces the footprint area on the circuit board while maintaining the required receiving volume for the electrical connector.
2Device complexity
If traditional heat dissipation structures are used, then the structure is simple, but the heat dissipation effect is insufficient
Solution Approach 1:
The heat dissipation element is nested within the receiving chamber of the metal shielding cage, utilizing the existing internal space of the connector assembly. This nested configuration provides effective heat dissipation functionality without adding external structural complexity or increasing the overall device footprint.
3Area of stationary object
If the receiving chamber extends perpendicular to the circuit board, then the occupied area on the circuit board is reduced, but the structural complexity increases
Solution Approach 1:
The metal shielding cage is designed to simultaneously serve multiple functions: providing electromagnetic shielding for the electrical connector, forming the receiving chamber structure that extends perpendicular to the circuit board, and supporting heat dissipation elements. This multi-functionality reduces the need for separate structural components, thereby limiting the increase in overall structural complexity.
