Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional control methods are used to attach hook devices to loads, then the attachment process can be completed, but the process becomes difficult and time-consuming due to vibrations and deflections from flexible guide units
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated optical detection and control system. The detection unit identifies the load position, and the control unit automatically adjusts the transport device's position and orientation, substituting human operators with an automated feedback control mechanism that compensates for vibrations and deflections in real-time.
Solution Approach 2:
The transport system performs self-positioning and self-alignment through the integrated detection and control units. The system automatically detects its own position relative to the load and makes corrective movements without external intervention, enabling autonomous attachment operations despite environmental disturbances.
2Ease of operation
If manual positioning by assistant personnel is used, then the hook device can be aligned with the load, but operator safety is compromised and productivity is reduced
Solution Approach 1:
The patent eliminates manual positioning operations by implementing an automated optical detection and control system. The detection unit captures load position data, and the control unit automatically adjusts the transport device's position and orientation, replacing human operators with an automated feedback control mechanism that maintains alignment accuracy while eliminating safety risks and improving productivity.
3Reliability
If the transport device is positioned above the load, then gripping is possible, but vibrations from the flexible rope or chain make gripping difficult
Solution Approach 1:
The patent implements a closed-loop feedback control system where the detection unit continuously monitors the position and orientation of the transport device relative to the load. The control unit processes this feedback information and automatically adjusts the transport device's position and orientation in real-time, compensating for vibrations and deflections caused by flexible guide units to maintain precise positioning for secure attachment.
4Extent of automation
If automatic positioning systems are implemented, then operator workload is reduced and automatic loading is enabled, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a unified automated system. The detection unit serves both for position detection and alignment verification, while the control unit coordinates transport device positioning, orientation adjustment, and attachment execution. This multi-functional integration achieves automatic loading capability while managing system complexity through functional consolidation.
