Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wireless transmitter (marker) is placed at a predetermined location for positioning, then positioning accuracy is improved, but positional deviation occurs when the marker is displaced, leading to erroneous vehicle operation
Solution Approach 1:
The system continuously monitors the position of wireless transmitters by comparing detected positions with stored reference positions. When a positional deviation is detected, the system generates feedback to alert the driver or automatically correct the positioning data, ensuring reliable vehicle operation despite marker displacement
Solution Approach 2:
The system pre-stores the correct positions of wireless transmitters in a database before vehicle operation. This preliminary action enables the system to quickly compare and detect any deviations from the expected positions, preventing erroneous operation before it occurs
2Measurement precision
If the vehicle autonomously approaches the marker for detection, then detection accuracy is improved, but detection time increases due to behavioral modification
Solution Approach 1:
The system applies partial vehicle behavior modification only when necessary for detection. Instead of continuously modifying behavior, the system makes targeted adjustments (such as slight position corrections or repositioning maneuvers) only when the marker is not initially detected, thereby minimizing time loss while achieving detection accuracy

AI summary
A vehicle control device 200 comprises: a marker detection unit 206 that uses a radio wave receiver 116 provided in a vehicle and receives a radio wave from a marker placed at a predetermined point to detect the marker; a vehicle behavior modification unit 210 that modifies a vehicle behavior such that the marker detection unit 206 detects the marker; a storage unit 204 that stores in advance a position of the marker; and a positional deviation determination unit 208 that determines whether there is a positional deviation of the marker, on the basis of a position of the marker detected by the marker detection unit 206 and the position of the marker stored in the storage unit 204.
