Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal shield is used to surround the insulative body to avoid EMI radiation, then EMI protection is improved, but device complexity and installation complexity increase
Solution Approach 1:
The patent applies composite materials by combining plastic material with electrically conductive material to create an electrically conductive plastic complex material. This composite material provides both structural properties of plastic and EMI shielding properties of conductive materials, eliminating the need for separate metal shields while maintaining EMI protection effectiveness.
Solution Approach 2:
The patent merges the functions of the insulative body and the EMI shield into a single integrated component. The electrically conductive plastic complex material simultaneously provides mechanical support, insulation, and EMI shielding functions, simplifying the device structure and reducing installation complexity compared to separate metal shield components.
2Object-affected harmful factors
If a metal shield is used to surround the insulative body to avoid EMI radiation, then EMI protection is improved, but manufacturing cost increases
Solution Approach 1:
The use of electrically conductive plastic complex material reduces manufacturing costs by eliminating the need for separate metal shield components and their associated assembly processes. The composite material can be manufactured in a single molding process, reducing part count, assembly steps, and overall manufacturing complexity.
Solution Approach 2:
By combining multiple functions (structural support, insulation, and EMI shielding) into a single integrated component made of electrically conductive plastic, the patent reduces the number of parts that need to be manufactured and assembled, thereby lowering manufacturing costs.
3Ease of manufacture
If conventional insulative material is used in the electrical socket, then manufacturing simplicity is maintained, but alien crosstalk and EMI radiation increase
Solution Approach 1:
The patent uses electrically conductive plastic complex material as a composite material that maintains the ease of manufacturing associated with plastic materials while adding EMI shielding and alien crosstalk prevention properties. The composite can be processed using standard plastic molding techniques, preserving manufacturing simplicity.
Solution Approach 2:
The patent changes the electrical parameters of the plastic material by incorporating electrically conductive materials, transforming it from an insulative material to an electrically conductive plastic complex material. This parameter change enables the material to provide EMI shielding and reduce alien crosstalk while maintaining ease of manufacturing.
