Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high signal transmission rates are used, then data transmission capability is improved, but electromagnetic radiation leakage increases
Solution Approach 1:
A shielding insert is introduced as an intermediary component between the conductors and the external environment. This shielding insert includes a first portion and a second portion that collectively form a shield to block electromagnetic radiation generated by high-speed data transmission, preventing it from escaping through the opening in the connector shell.
Solution Approach 2:
The shielding insert is constructed from composite materials with different electromagnetic radiation absorbing characteristics. The first portion has a first electromagnetic radiation absorbing characteristic while the second portion has a second electromagnetic radiation absorbing characteristic, creating a multi-layered shielding structure that effectively blocks electromagnetic radiation across different frequencies and directions.
2Object-affected harmful factors
If electromagnetic radiation is blocked, then electromagnetic interference is reduced, but device complexity increases
Solution Approach 1:
The shielding insert is segmented into a first portion and a second portion, each with different electromagnetic radiation absorbing characteristics. This segmentation allows the shield to address different aspects of electromagnetic radiation blocking while maintaining a manageable structure that can be integrated into the connector without excessive complexity.
Solution Approach 2:
The shielding insert serves multiple functions: it blocks electromagnetic radiation leakage, provides structural support within the connector, and can be integrated with the cable assembly. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving effective electromagnetic interference reduction.
