Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual splicing of shielding braids to grounding wire is performed, then grounding connection is achieved, but harness preparation complexity and time increase
Solution Approach 1:
The patent merges multiple individual grounding connections into a single common grounding plate that simultaneously connects to all shielding braids. Instead of splicing each shield individually to a grounding wire, the common grounding plate provides a centralized connection point that electrically bonds all shields together and to the grounding cable in one operation, thereby reducing harness preparation complexity while maintaining grounding reliability.
Solution Approach 2:
The common grounding plate serves multiple functions: it acts as a grounding connection point, provides electrical bonding between multiple shields, and simplifies the harness preparation process. This multi-functional component replaces the need for individual splicing operations for each shield, achieving universal grounding for all connected cables through a single device.
2Reliability
If individual splicing of shielding braids is performed, then grounding is achieved, but time consumption increases
Solution Approach 1:
The common grounding plate combines multiple grounding connections into a single operational step. By providing a common connection point that accepts all shielding braids simultaneously, it eliminates the sequential splicing process required by traditional methods, thereby significantly reducing the time required for harness preparation while maintaining reliable grounding connections.
Solution Approach 2:
The common grounding plate is pre-configured with multiple connection points and bonding structures before assembly. This preliminary preparation allows for rapid connection of multiple shields during assembly, eliminating the need for time-consuming field splicing operations and reducing overall harness preparation time.
3Reliability
If traditional grounding method is used, then grounding cable connection is achieved, but sealed connector design becomes complicated
Solution Approach 1:
The common grounding plate integrates multiple grounding functions into a single component that can be seamlessly incorporated into sealed connector designs. By consolidating the grounding connections for multiple cables into one centralized structure, it simplifies the sealing and assembly process, making it easier to design and manufacture sealed connectors compared to managing multiple individual grounding connections.
