Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional verification methods using pseudo-defective products are employed, then defect detection function verification is achieved, but manufacturing line operation must be stopped leading to reduced productivity
Solution Approach 1:
The invention creates a virtual pseudo-defective product through coordinate information instead of using physical pseudo-defective products. The verification system generates fake defect positions in virtual space that correspond to actual product positions, allowing the inspection device to detect these virtual defects without stopping the manufacturing line. This copying approach maintains productivity while achieving verification purposes.
Solution Approach 2:
The invention introduces a verification system as an intermediary between the inspection device and the manufacturing line. This system receives coordinate information from the inspection device, generates virtual pseudo-defective product positions, and feeds them back to verify detection accuracy. The intermediary enables continuous verification without disrupting the manufacturing flow.
2Reliability
If frequent verification is performed to ensure quality management reliability, then detection accuracy is maintained, but verification work burden increases significantly
Solution Approach 1:
The verification system performs automatic verification using coordinate information from the inspection device itself. The system generates virtual pseudo-defective products based on actual product positions and automatically checks detection accuracy without requiring manual intervention. This self-service approach reduces verification work burden while maintaining frequent verification for quality reliability.
Solution Approach 2:
The invention enables continuous verification to be performed alongside normal inspection operations. By using virtual pseudo-defective products generated from coordinate information, the system can continuously verify detection accuracy without interrupting the manufacturing line or requiring separate verification time slots, thus maintaining quality reliability without increasing time loss.
3Reliability
If physical pseudo-defective products are used for verification, then detection function is verified, but the inspection target articles are affected and operating rate decreases
Solution Approach 1:
The invention creates virtual copies of pseudo-defective products in coordinate space rather than using physical objects. The verification system generates fake defect positions that match actual product positions, allowing the inspection device to verify detection functionality without physical interference. This copying method eliminates the need to remove or alter actual products, maintaining full manufacturing throughput.
Solution Approach 2:
The invention replaces the mechanical approach of using physical pseudo-defective products with an information-based virtual system. Instead of physically inserting test objects into the manufacturing line, the system uses coordinate data and virtual positioning to achieve verification. This substitution eliminates mechanical interference with the production process while maintaining verification effectiveness.

AI summary
There is provided an article inspection verification system provided in an article inspection line including a plurality of article inspection devices that determine whether an inspection target article is a non-defective product or a defective product. The article inspection verification system includes physical effect generators that generate a physical effect that causes the inspection target article to be determined to be the defective product while the inspection target article passes through inspection sections corresponding each of article inspection devices, and a physical effect control unit that stores generation conditions of the physical effect by the physical effect generators and drives the physical effect generators in accordance with the generation conditions during an operation of the article inspection line.
