Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerous sensors are mounted to detect conveyance abnormalities, then detection capability is improved, but device complexity increases and identification time is extended
Solution Approach 1:
The patent introduces a reference conveying container as an intermediary object to mediate the detection of conveyance abnormalities. Instead of using multiple sensors to directly detect various abnormalities, the system uses the reference container (which has known characteristics) as a mediator to compare against the actual conveying container, thereby inferring abnormalities through comparison rather than direct detection. This reduces sensor quantity while maintaining detection capability.
Solution Approach 2:
The patent creates a copy (reference conveying container) that replicates the essential characteristics of the actual conveying container. By comparing the behavior of this reference copy against the actual container during conveyance, the system can detect abnormalities without needing numerous sensors. The reference container serves as a simplified model that enables indirect measurement of conveyance conditions.
2Measurement precision
If numerous sensors are mounted to detect conveyance abnormalities, then detection capability is improved, but identification time is extended
Solution Approach 1:
The reference conveying container acts as a mediator that enables rapid comparison-based diagnosis. When an abnormality occurs, the system immediately compares the actual container's conveyance behavior against the reference container's known behavior, allowing for quick identification of the specific abnormality type without time-consuming sensor data analysis from multiple sources.
Solution Approach 2:
The system implements feedback by continuously monitoring the position and conveyance state of both the actual and reference containers, comparing their behaviors in real-time, and providing immediate feedback when deviations are detected. This closed-loop feedback mechanism enables rapid abnormality identification and response.
3Productivity
If conveyance speed is increased to improve efficiency, then productivity is improved, but stability decreases due to undetected abnormalities
Solution Approach 1:
The system performs preliminary action by pre-establishing the reference conveying container with known characteristics before actual conveyance operations begin. This reference is prepared in advance to serve as a baseline for comparison, enabling the system to detect abnormalities even during high-speed conveyance without compromising stability, as the comparison mechanism is already in place and requires minimal processing time.

AI summary
There are provided a sample conveying device and a sample conveyance method capable of determining a cause of an abnormality in a conveyance speed more quickly than in the related art. In a conveying device 501, a general conveyance speed of a conveying container 102 is obtained from a position of the conveying container 102 detected by a position detection unit 110 to determine whether the general conveyance speed is abnormal, and when it is determined that the general conveyance speed is abnormal, an inspection conveying container 105 is conveyed, and the cause of the abnormality in the general conveyance speed is determined based on the conveyance speed of the inspection conveying container 105.
