Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal shell is installed on the insulating body to provide shielding, then the shielding effect is improved, but the device complexity increases
Solution Approach 1:
The patent combines the shielding cage and the retaining portion into a single integrated component. The shielding cage serves dual functions: providing electromagnetic shielding for the conductive terminals and mechanically retaining the electrical connector in the installation cavity. This merging eliminates the need for separate retaining structures, thereby reducing device complexity while maintaining effective shielding.
Solution Approach 2:
The shielding cage is designed as a multi-functional component that simultaneously provides electromagnetic shielding and mechanical retention. By making the shielding structure universal for both shielding and retention purposes, the patent reduces the overall number of components needed in the assembly, addressing the contradiction between improved shielding and reduced complexity.
2Adaptability or versatility
If the conductive housing defines a receiving slot to receive the mating connector, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The retaining portion is designed to preliminarily position and secure the electrical connector in the installation cavity before the mating connector is inserted. This preliminary action ensures proper alignment and reduces the tolerance requirements for the receiving slot, thereby maintaining adaptability while lowering manufacturing precision requirements.
3Reliability
If the shielding cage surrounds the conductive terminals to improve shielding, then the signal transmission quality is improved, but the device complexity increases
Solution Approach 1:
The patent merges the shielding function with the retention function in a single shielding cage component. This eliminates the need for additional separate retention mechanisms, thereby reducing device complexity while maintaining effective electromagnetic shielding around the conductive terminals for improved signal transmission quality.
