Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shielding shells, welding, conductive plastics are added to optimize SI performance, then electrical and signal integrity performance is improved, but design and manufacturing costs increase, processes become complicated, production duration increases and product qualification rates decrease
Solution Approach 1:
The patent removes the need for external shielding shells and complex conductive plastic structures by integrating electromagnetic shielding functionality directly into the terminal component structure through optimized ground terminal arrangements and casing design, thereby simplifying the overall device while maintaining SI performance
Solution Approach 2:
The patent combines multiple functions into the terminal components themselves - the terminal components serve both as electrical connectors and as electromagnetic shielding elements through their ground terminals and positioning structures, eliminating the need for separate shielding components
2Reliability
If shielding shells, welding, conductive plastics are added to optimize SI performance, then electrical and signal integrity performance is improved, but manufacturing costs increase
Solution Approach 1:
The patent uses standard, easily manufactured terminal components with integrated ground terminals rather than expensive custom shielding structures, achieving cost-effective SI optimization through conventional manufacturing processes
Solution Approach 2:
The patent optimizes SI performance by adjusting geometric parameters of the terminal components - such as ground terminal width, spacing, and positioning - rather than adding expensive materials or complex structures, thereby reducing manufacturing costs while improving performance
3Reliability
If shielding shells, welding, conductive plastics are added to optimize SI performance, then electrical and signal integrity performance is improved, but production duration increases
Solution Approach 1:
The patent incorporates electromagnetic shielding functionality into the terminal components during the initial molding process, rather than requiring subsequent assembly steps with separate shielding components, thereby reducing production duration while maintaining SI performance
