Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the mobile object is guided to face the target object using a near-infrared camera, then the mobile object can automatically move towards the target, but misalignment between the target object and the mobile object occurs leading to improper conveyance
Solution Approach 1:
The patent replaces the near-infrared camera-based guidance system with a laser-based detection system. The laser detector measures the position of the target object relative to the mobile object with higher precision, enabling accurate alignment. This substitution of detection mechanism resolves the contradiction by maintaining automation while significantly improving measurement precision for alignment.
2Device complexity
If the mobile object uses simple position detection, then the system remains simple, but the target object cannot be accurately aligned with the mobile object
Solution Approach 1:
The patent introduces a laser detector to replace simple position detection methods. The laser detector provides precise measurement of the target object's position relative to the mobile object, enabling accurate conveyance. This addition of a laser-based detection system resolves the contradiction by accepting increased device complexity to achieve the required manufacturing precision for proper conveyance.

AI summary
A control method for a mobile object is a control method for a mobile object that automatically moves. The control method includes detecting a position of a target object to be conveyed with respect to the mobile object, and acquiring, based on a detection result of the position of the target object, positional information on the target object indicating the position of the target object with respect to the mobile object in a state in which a fork disposed on the mobile object is inserted into a hole formed on the target object.
