Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a variety of share geometries are used to control soil cultivation conditions, then soil cultivation quality can be adapted to different soil types and speeds, but device complexity increases and consistency is lost
Solution Approach 1:
The patent applies dynamics by making the share geometry adjustable during operation. The share can change its curvature radius and camber angle dynamically to adapt to different working speeds and soil conditions, replacing the need for multiple fixed geometry shares. This allows a single share design to perform multiple functions across varying operational parameters.
Solution Approach 2:
The patent changes geometric parameters of the share (curvature radius, camber angle, spread angle) based on operating conditions. By adjusting these parameters in response to working speed and soil type, the system maintains optimal soil cultivation quality without requiring multiple different share designs, thus reducing device complexity while preserving adaptability.
2Productivity
If working speed increases, then productivity improves, but soil cultivation quality becomes inconsistent and mixing effect changes
Solution Approach 1:
The share geometry is made dynamic to compensate for speed variations. At higher working speeds, the share automatically adjusts its curvature and camber to maintain the appropriate soil throwing and mixing characteristics, ensuring consistent cultivation quality across the full range of operational speeds.
Solution Approach 2:
The system uses feedback from speed sensors and soil condition monitoring to automatically adjust share geometry parameters. This closed-loop control ensures that regardless of the working speed, the share maintains optimal engagement with the soil to produce consistent cultivation results.
3Power
If share curvature radius is reduced for strong mixing effect, then soil dynamics improve, but traction requirement increases
Solution Approach 1:
The system dynamically adjusts the share curvature radius based on the desired mixing intensity and soil conditions. When strong mixing is required, the curvature radius is reduced to increase soil dynamics, but this is compensated by adjusting other parameters like camber angle and spread angle to optimize traction efficiency, preventing excessive force requirements.
