Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate grounding is performed for each surface of the circuit board, then reliable electrical connectivity is achieved, but the connection process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple grounding functions into a single ground bar that simultaneously grounds coaxial wires from both the first surface and second surface of the circuit board. This merging of grounding operations eliminates the need for separate grounding processes for each surface, thereby maintaining reliable electrical connectivity while significantly simplifying the connection process and reducing manufacturing complexity
2Reliability
If multiple ground bars are used for different surfaces, then proper grounding is achieved, but the number of components and processing steps increases
Solution Approach 1:
The invention merges the function of multiple ground bars into a single ground bar that serves both the first surface and second surface grounding requirements. This single ground bar component simultaneously provides proper grounding for coaxial wires from both surfaces, thereby maintaining reliable grounding while reducing the total number of components and eliminating redundant processing steps
3Reliability
If coaxial wires are processed multiple times for grounding, then complete grounding coverage is achieved, but productivity decreases
Solution Approach 1:
The patent implements preliminary action by designing the ground bar with pre-formed contact structures that can simultaneously engage with coaxial wires from both surfaces in a single operation. The ground bar includes first contact structures for the first surface and second contact structures for the second surface, both integrated into one component that performs complete grounding coverage in one step, thereby eliminating multiple processing steps and significantly improving connection efficiency
