Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual emasculation and pollination are used, then operation flexibility is maintained, but productivity is low and labor costs are high
Solution Approach 1:
The breeding robot is divided into functional modules: walking device for movement, telescopic arm for positioning, saw blade for emasculation, blower for pollination, and CCD detector for detection. Each module performs a specific task, enabling automated breeding operations while managing system complexity through modular design
Solution Approach 2:
The robot autonomously navigates to target maize plants using satellite positioning and CCD detection, automatically performs emasculation with the saw blade, and completes pollination using the blower. The system serves itself by integrating detection, decision-making, and execution functions into a single automated unit
2Productivity
If manual breeding operations are performed, then equipment cost is low, but economic cost is high due to labor intensity
Solution Approach 1:
The breeding robot integrates multiple functions into a single platform: the walking device enables autonomous movement to different maize plants, the telescopic arm provides adjustable positioning, the saw blade performs emasculation, and the blower executes pollination. This multi-functional design improves breeding operation speed while consolidating equipment requirements
Solution Approach 2:
The patent replaces manual mechanical operations with an automated robotic system. The satellite positioning system and CCD detector substitute for human visual inspection and positioning, while the first motor, second motor, and blower replace manual emasculation and pollination actions, significantly increasing breeding operation speed
3Productivity
If automated breeding robot is deployed, then productivity increases, but device complexity and initial investment increase
Solution Approach 1:
The robot system is segmented into distinct functional units: walking device with satellite positioning, telescopic arm with adjustable length, rotating bracket with saw blade, blower with air duct, and CCD detector. This segmentation allows each component to be optimized independently while contributing to overall breeding efficiency
Solution Approach 2:
The robot employs dynamic components including the telescopic arm that can extend and retract to reach different maize heights, the rotating bracket that positions the saw blade and blower, and the walking device that moves between plants. These dynamic elements enable the system to adapt to varying field conditions while maintaining automated operation
