Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wheeled platforms are used to transport trays in a warehouse system, then transportation capability is improved, but dropping accuracy deteriorates
Solution Approach 1:
The patent replaces the mechanical positioning system of wheeled platforms with an autonomous mobile robot equipped with sensors and control systems. The robot uses laser sensors to detect three-dimensional information and a control unit to calculate precise positioning, substituting mechanical transport with intelligent autonomous navigation to achieve both transportation capability and high dropping accuracy
Solution Approach 2:
The patent implements a feedback mechanism where the sensor continuously detects the three-dimensional shape and position of structures, the control unit compares detected data with master data, and adjusts the robot's position accordingly. This closed-loop feedback system enables precise dropping by constantly monitoring and correcting the robot's location relative to the target dropping position
2Manufacturing precision
If three-dimensional shape detection is implemented, then dropping accuracy is improved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional integrated system where a single control unit performs multiple functions: storing master data, processing sensor data, calculating positions, and controlling robot movement. The sensor system serves both navigation and positioning purposes. This consolidation of functions into unified components achieves high dropping accuracy while managing system complexity through functional integration
