Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measurement rejection devices are provided for each power supply stand, then pairing accuracy between power transmission and receiving devices is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the measurement rejection function into the existing vehicle control device, eliminating the need for separate measurement rejection devices at each power supply stand. The control device integrates multiple functions including automatic parking control, non-contact charging control, and measurement rejection capabilities into a single unified system, thereby reducing overall device complexity while maintaining pairing accuracy.
Solution Approach 2:
The vehicle control device is designed to perform multiple functions: automatic parking control, non-contact charging control, and measurement rejection. This multi-functional approach allows a single device to replace what would otherwise require multiple separate devices, reducing system complexity while maintaining the necessary measurement and pairing capabilities.
2Reliability
If separate measurement rejection devices are provided for each power supply stand, then pairing reliability is improved, but cost increases
Solution Approach 1:
By merging the measurement rejection functionality into the existing vehicle control device, the patent eliminates the need for additional separate devices at each power supply stand, thereby reducing manufacturing costs while maintaining pairing reliability through the integrated system.
Solution Approach 2:
The vehicle control device performs measurement rejection functions autonomously as part of its integrated operations, eliminating the need for separate dedicated devices and reducing overall system cost while maintaining reliable pairing through self-contained functionality.
3Ease of operation
If the vehicle control device integrates automatic parking and non-contact charging control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent integrates automatic parking control and non-contact charging control into a single vehicle control device, allowing both functions to be managed through one unified system. This integration improves ease of operation by providing centralized control while managing complexity through shared hardware and coordinated software management.
Solution Approach 2:
The vehicle control device is designed as a multi-functional system that handles both automatic parking and non-contact charging operations. This universal approach allows a single device to perform multiple functions that would otherwise require separate systems, improving operational simplicity while containing complexity through integrated design.

AI summary
A vehicle control device mounted on a vehicle, includes: an automatic parking control unit that performs automatic parking control, and a non-contact charging control unit that performs non-contact charging control. Further, while the automatic parking control unit performs the automatic parking control, the non-contact charging control unit specifies radio communication information associated with a parking space of a parking target with reference to map information, and performs pairing between a power transmission device and a power receiving device by using the specified radio communication information.
