Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voltage adjusting method detecting voltage and adjusting output voltage adjustment resistance is used, then predetermined voltage can be supplied to connector unit, but device complexity and cost increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring connection members with different numbers of parallel lines (one-line, two-line, three-line connection members) before use. These connection members are prepared in advance with different electrical resistance characteristics, allowing the system to select the appropriate connection member based on cable length without requiring real-time detection or adjustment mechanisms. This eliminates the need for voltage detection circuits and adjustable resistance elements, thereby reducing device complexity while maintaining reliable voltage supply.
Solution Approach 2:
The patent changes the electrical parameter (electrical resistance) by varying the number of parallel lines in the connection member. By selecting connection members with different numbers of parallel lines, the system adjusts the overall electrical resistance to compensate for voltage drops caused by different cable lengths. This parameter change approach allows voltage compensation without adding complex control systems, resolving the contradiction between reliability and device complexity.
2Adaptability or versatility
If cable length varies to adapt to different vehicle structures, then adaptability improves, but voltage supplied to connector unit varies
Solution Approach 1:
The patent changes the electrical resistance parameter of the connection member by selecting different numbers of parallel lines based on cable length. When cable length increases causing greater voltage drop, a connection member with more parallel lines (lower resistance) is selected to compensate. This dynamic parameter adjustment maintains consistent voltage supply to the connector unit while allowing flexible adaptation to different vehicle structures and installation positions.
Solution Approach 2:
The patent introduces dynamics by making the connection member selection adaptable to different operating conditions (cable lengths). Instead of using a fixed connection member configuration, the system dynamically selects the appropriate connection member type based on the actual cable length, enabling the system to maintain optimal performance across varying installation scenarios while ensuring consistent voltage supply.

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.
