Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a wheeled platform is used to transport trays in a warehouse system, then the transportation capability is improved, but the dropping accuracy of trays at designated positions deteriorates
Solution Approach 1:
The patent replaces the mechanical positioning system of wheeled platforms with an optical sensing and control system. A sensor detects the actual position of the platform, and a controller processes this information to calculate position deviations. The system then commands the platform to adjust its position, substituting passive mechanical transport with active optical-mechanical control to achieve precise dropping accuracy while maintaining transportation capability
Solution Approach 2:
The patent implements a feedback control mechanism where a sensor continuously detects the actual position of the transporting platform, and this detection information is fed back to a controller. The controller compares the actual position with the target position, calculates deviations, and generates correction commands. This closed-loop feedback system enables the platform to automatically adjust its position, resolving the contradiction between transportation speed and dropping accuracy
2Manufacturing precision
If the dropping position accuracy is improved through better control systems, then the item placement precision is improved, but the device complexity increases
Solution Approach 1:
The patent enables the transporting platform to perform self-positioning and self-correction. The sensor on the platform detects its own position, the controller on the platform processes the position information and calculates deviations, and the platform executes self-adjustment based on controller commands. This self-service capability achieves high placement precision without requiring complex external control infrastructure
Solution Approach 2:
The patent integrates multiple functions into a single controlling device: position detection, data processing, deviation calculation, and control command generation are all performed by the controller. This multi-functional integration simplifies the overall system architecture while achieving high precision item placement, avoiding the need for separate complex subsystems
