Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cable length is increased to connect feeding unit and connector unit in vehicles with different structures, then the adaptability to different vehicle types is improved, but the voltage supplied to the connector unit varies due to voltage drop
Solution Approach 1:
The patent applies dynamics by making the connection configuration adjustable rather than fixed. The system can dynamically change the number of parallel lines in the connection between feeding unit and connector unit based on the actual cable length and voltage requirements, allowing adaptation to different vehicle configurations while maintaining stable voltage supply.
Solution Approach 2:
The patent changes the electrical parameters of the connection by adjusting the number of parallel lines. This parameter change allows the system to compensate for voltage drop caused by different cable lengths, thereby maintaining reliable voltage supply across various vehicle types with different installation configurations.
2Reliability
If a voltage adjusting method using output voltage adjustment resistance is used, then the predetermined voltage can be supplied to the connector unit, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the voltage adjustment function from the feeding unit by utilizing the connection structure itself. Instead of adding adjustment resistance within the feeding unit, the system uses the inherent resistance characteristics of different connection configurations (different numbers of parallel lines) to achieve voltage adjustment, thereby simplifying the feeding unit structure.
Solution Approach 2:
The connection structure serves multiple functions: it provides electrical connection between feeding unit and connector unit, and simultaneously acts as the voltage adjustment mechanism through its configurable parallel line configuration. This multi-functionality eliminates the need for separate voltage adjustment components, reducing device complexity and cost.
3Reliability
If the line diameter in the cable is increased to reduce voltage drop, then the electric resistance decreases, but the flexibility of the cable deteriorates
Solution Approach 1:
The patent segments the current path into multiple parallel lines instead of using a single thick line. By dividing the current conduction into several thinner parallel conductors, the system achieves low overall resistance while maintaining the flexibility characteristics of thinner wires, thus avoiding the rigidity problem associated with thick cables.
Solution Approach 2:
The patent combines multiple thin parallel lines to create an effective conductor with low resistance. By merging several flexible thin conductors in parallel, the system achieves the electrical performance of a thick conductor while retaining the mechanical flexibility of thin conductors, enabling easy wiring installation.

AI summary
Each of a feeding unit and a connector unit is provided with power supply ports and ground ports. In at least one of a connection of the power supply ports of the feeding unit and the power supply ports of the connector unit and a connection of the ground ports of the feeding unit and the ground ports of the connector unit, the number of parallel lines in at least a partial section is changed according to a length of the connection. In this way, a voltage drop between the feeding unit and the connector unit is adjusted.
