Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ground terminals are stacked radially, then multiple ground connections are achieved, but the space required increases significantly
Solution Approach 1:
The patent transitions from radial stacking of ground terminals to a linear arrangement where pin terminals and socket terminals are disposed in opposing directions along a longitudinal axis. This dimensional change allows multiple ground connections to be achieved in a compact linear footprint rather than requiring radial space expansion.
Solution Approach 2:
The patent employs nested structures where pin terminals are inserted into socket terminals, and the side holder is inserted into the housing. This nesting approach maximizes space utilization by placing components within the voids and spaces of other components, reducing overall connector volume while maintaining multiple ground connections.
2Ease of manufacture
If manual manufacturing processes are used for assembling connectors, then flexibility is maintained, but productivity decreases
Solution Approach 1:
The connector is divided into distinct modular components including ground terminals, pin terminals, socket terminals, side holders, and housing. This segmentation allows each component to be manufactured separately using automated processes and then assembled through standardized insertion and coupling mechanisms, enabling both high productivity and manufacturing flexibility.
Solution Approach 2:
The patent designs standardized terminal structures with universal insertion interfaces. The pin terminals and socket terminals feature complementary geometries that enable automated insertion and positioning. The side holder provides universal support and positioning functionality across different terminal configurations, facilitating automated assembly processes.
3Ease of operation
If electric wires are exposed in the connector, then connectivity is achieved, but safety and aesthetics deteriorate
Solution Approach 1:
The patent places electric wires and conductive elements within nested protective structures. The wires are enclosed within the housing, with connection points accessible only through controlled interfaces. This nested arrangement maintains electrical connectivity while protecting exposed conductive elements from environmental damage and accidental contact.
Solution Approach 2:
The patent employs the housing as a protective shell that encloses and protects internal electrical components. The housing structure provides mechanical protection and environmental sealing while allowing controlled access to connection points, thereby maintaining safety without compromising connectivity functionality.
