Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If rigid transmission is adopted in seedling separating device, then structural simplicity is improved, but movement stability deteriorates due to large vibration
Solution Approach 1:
The patent replaces rigid transmission components with a flexible synchronous belt transmission system. The synchronous belt, being a flexible element, can damp impact and absorb vibration during operation, thereby reducing large vibrations while maintaining transmission functionality. This directly addresses the contradiction by using flexible materials to improve movement stability without significantly increasing structural complexity.
Solution Approach 2:
The patent changes the physical parameters of the transmission system by introducing elastic deformation capabilities through the flexible synchronous belt. The belt's ability to stretch and return to its original shape allows it to absorb vibration energy, transforming the rigid transmission system into one with controlled flexibility that maintains stability.
2Ease of manufacture
If rigid transmission is used, then manufacturing simplicity is improved, but seedling separating accuracy deteriorates due to vibration
Solution Approach 1:
The flexible synchronous belt serves as a vibration-damping element that reduces large vibrations during seedling separation. This improvement in vibration control directly enhances the accuracy of seedling separating while the belt itself remains a relatively simple component to manufacture and install.
3Ease of operation
If manual continuous work is used for seedling transplanting, then operational simplicity is improved, but productivity deteriorates due to fatigue and seedling missing
Solution Approach 1:
The patent implements an automated seedling separating device that performs the transplanting operation autonomously. The flexible synchronous belt transmission system enables continuous, fatigue-free operation at higher speeds, eliminating the limitations of manual work while maintaining ease of operation through automated control.
Solution Approach 2:
The seedling separating device operates through periodic cyclic motions driven by the synchronous belt transmission. The motor drives the transmission system in regular intervals, enabling continuous high-speed automated transplanting that overcomes the productivity limitations of manual continuous work.
