Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a substrate is used to connect contacts, then the electrical connector can be assembled, but the length of the electrical connector increases
Solution Approach 1:
The patent removes the substrate from the electrical connector assembly, extracting the unnecessary component that was increasing length without adding functional value. The contacts are redesigned to be directly mounted on the insulative housing, eliminating the intermediate substrate layer and reducing overall connector length.
Solution Approach 2:
The patent merges the substrate function directly into the insulative housing structure. The housing is designed to directly support and position the contacts, combining what were previously separate components (housing and substrate) into a single integrated structure, thereby reducing the number of parts and overall length.
2Ease of manufacture
If a substrate is used to connect contacts, then the electrical connector can be assembled, but the structure becomes more complex
Solution Approach 1:
The substrate is extracted and removed from the assembly, eliminating the additional layer of complexity it introduced. The contacts are directly integrated into the housing structure, reducing the number of discrete components and simplifying the overall assembly process.
Solution Approach 2:
The housing and substrate functions are merged into a single integrated component. The insulative housing is designed with built-in contact support features, eliminating the need for a separate substrate and reducing structural complexity while maintaining assembly capability.
3Length of stationary object
If conductive terminals are soldered directly to the cable, then the length decreases, but the manufacturing precision requirement increases
Solution Approach 1:
The conductive terminals are pre-formed with integrated soldering portions that are specifically designed and positioned before final assembly. This preliminary preparation of the soldering interfaces ensures proper alignment and reduces the precision requirements during the actual soldering process to the cable.
Solution Approach 2:
The soldering portions of the conductive terminals are designed with specific local characteristics optimized for soldering to the cable. The middle portions are bent to position the soldering portions at optimal locations, creating localized quality enhancements that facilitate easier and more precise soldering while maintaining overall length reduction.

AI summary
A cable connector assembly includes an insulative housing, a cable defining a number of core wires, and a number of conductive terminals held in the insulative housing. Each conductive terminal includes a contacting portion, a soldering portion soldered to the cable, and a middle portion between the contacting portion and the soldering portion. The conductive terminals include a number of first terminals in a row and a number of second terminals in another row. Both the first terminals and the second terminals include a pair of power terminals and a pair of grounding terminals. The soldering portion of only one kind conductive terminal of the first terminals is bent to a plane of the soldering portion of a corresponding conductive terminal of the second terminals with same function to form a shared soldering portion. The shared soldering portion is electrically connected to a corresponding core wire.
