Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive shielding material is used to reduce electromagnetic interference and crosstalk during high-speed signal transmission, then signal quality is improved, but device complexity increases due to the need for multiple shielding and isolation components
Solution Approach 1:
The connector is divided into multiple functional components: conductive shielding material component, insulating material component, major non-shielding terminal component, and minor non-shielding terminal component. Each segment performs a specific function (shielding, isolation, signal transmission) to collectively reduce interference while maintaining manageable complexity through modular design
Solution Approach 2:
Different regions of the connector are assigned different material properties and functions: conductive regions for shielding (major and minor shielding terminal components), insulating regions for isolation (insulating material component), and non-shielding regions for signal transmission (major and minor non-shielding terminal components). This localized functional differentiation optimizes interference reduction without requiring uniform complexity throughout the entire device
2Reliability
If multiple terminal components and shielding materials are integrated to provide comprehensive shielding, then interference reduction is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple functional components (conductive shielding material, insulating material, major non-shielding terminal component, minor non-shielding terminal component) are merged into a single integrated connector structure. This consolidation allows all components to be manufactured and assembled as one unit, reducing the number of separate manufacturing processes and assembly steps required
Solution Approach 2:
The connector employs composite material construction, combining conductive materials (for shielding terminals), insulating materials (for isolation), and non-shielding conductive materials (for signal terminals) into a unified structure. This composite approach enables multi-functional performance within a single manufactured component, simplifying production compared to assembling separate parts

AI summary
An electrical connector comprising a major shielding conductive terminal, a major non-shielding conductive terminal, a minor shielding conductive terminal, a minor non-shielding conductive terminal, and a conductive shielding material component. The conductive shielding material component is disposed between the major conductive terminal and the minor-side conductive terminal, and comprises a conductive plastic material and a conductive metal material, wherein the conductive plastic material, the conductive metal material, the major shielding conductive terminal, and the minor shielding conductive terminal are electrically connected to transmit shielding signals. Thus, the conductive plastic material, the conductive metal material, the major shielding conductive terminal, and the minor shielding conductive terminal provide shielding for the signal transmission between the major non-shielding conductive terminal and the minor non-shielding conductive terminal. In this manner, interference encountered by the electrical connector during high-speed signal transmission can be effectively reduced, thereby optimizing the quality of high-speed signal transmission.
