Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a defective component is detected and evacuated from the component line, then assembly correctness is improved, but production time is increased due to component evacuation and vehicle evacuation procedures
Solution Approach 1:
The system performs preliminary identification of defective components before they reach the assembly point. When a defect is detected, the component is evacuated from the component line and the corresponding vehicle is evacuated from the manufacturing line in advance, preventing incorrect assembly before it occurs. This preliminary action ensures assembly correctness while minimizing disruption to the overall production flow.
Solution Approach 2:
The system implements a feedback mechanism where defect detection information from the component line is immediately communicated to the manufacturing line control system. This feedback enables real-time coordination between component evacuation and vehicle evacuation, allowing the system to respond quickly to defects and maintain production efficiency while ensuring assembly correctness.
2Productivity
If the manufacturing line continues operating at high speed, then productivity is improved, but assembly correctness deteriorates when defective components are present
Solution Approach 1:
The system maintains high manufacturing speed through continuous feedback monitoring of component quality. When a defective component is detected, the feedback mechanism triggers immediate evacuation of both the component and the corresponding vehicle, allowing the high-speed production to continue uninterrupted for good components while preventing incorrect assembly when defects are present.
Solution Approach 2:
The system performs self-service quality control by automatically detecting defective components and coordinating their evacuation with the corresponding vehicle evacuation. This self-service mechanism operates continuously at high speed without requiring manual intervention, maintaining both productivity and assembly correctness through automated defect response.
3Manufacturing precision
If manual inspection and intervention are used to handle defective components, then assembly correctness is improved, but device complexity and manual work requirements increase
Solution Approach 1:
The system replaces manual inspection and intervention with automated self-service functionality. The defect detection system automatically identifies defective components, and the control system automatically coordinates evacuation of both the component and the corresponding vehicle. This eliminates the need for manual quality control while maintaining assembly correctness, reducing device complexity compared to manual systems.
Solution Approach 2:
The system substitutes mechanical manual inspection and handling with automated detection and control mechanisms. Optical or sensor-based detection systems replace human visual inspection, and automated control systems replace manual decision-making and coordination. This substitution maintains assembly correctness while reducing the complexity associated with manual intervention systems.

AI summary
The device includes: a identifying unit that specifies a corresponding moving body to which a defective component evacuated from a component line through which a plurality of components flow is assembled among one or more moving bodies moving the manufacturing line by unmanned operation, wherein the component line merges with the manufacturing line in an assembly area for performing assembly of the component to the moving body; an evacuation instruction for evacuating the corresponding moving body from the manufacturing line by unmanned operation; and an instruction unit that issues at least one of a skip instruction for skipping assembly of the corresponding moving body.
