Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual pruning is used in large plantations, then workers can perform pruning tasks, but labor intensity is high and work efficiency is low
Solution Approach 1:
The patent replaces manual mechanical pruning operations with an automated robot system that uses RFID tags, GPS positioning, and automated pruning mechanisms. The robot autonomously navigates the plantation, identifies trees via RFID tags, and performs pruning operations without human intervention, thereby eliminating labor intensity while significantly improving pruning efficiency.
2Reliability
If manual pruning is performed in large areas, then pruning tasks can be completed, but missed pruning and repeated pruning occur due to worker fatigue
Solution Approach 1:
The patent implements a feedback mechanism where RFID tags on each tree provide unique identification, and the system records which trees have been pruned. The robot continuously receives positioning information from GPS and compares its current location with the pruning task list, ensuring that each tree is pruned exactly once. This feedback loop eliminates missed pruning and repeated pruning, maintaining high reliability and work consistency regardless of plantation size.
3Measurement precision
If RFID, GPS and WIFI positioning systems are integrated, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional integrated positioning system where RFID tags serve dual purposes: tree identification and positioning reference. The GPS receiver provides location data that is processed by the control unit to determine both the robot's position and the nearest unpruned tree. WIFI positioning supplements this data for enhanced accuracy in specific scenarios. By making each component serve multiple functions, the system achieves high positioning accuracy without proportionally increasing complexity.
