Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual garlic sowing is used, then the bulbils can be planted upwards with correct orientation, but the labor intensity is high and production efficiency is low
Solution Approach 1:
The patent replaces manual mechanical sowing with an automated mechanical system that uses electromagnetic actuators to control bulbil orientation. The system employs sensors to detect bulbil orientation and automatically adjusts it using electromagnetic forces, eliminating the need for manual intervention while maintaining correct planting orientation.
Solution Approach 2:
The system enables self-service by automatically detecting bulbil orientation through sensors and adjusting the orientation using electromagnetic actuators without human intervention. The mechanism autonomously completes the sowing process with correct orientation, improving both ease of operation and productivity.
2Productivity
If automated garlic sowing is implemented, then production efficiency is improved, but the bulbil orientation control is insufficient
Solution Approach 1:
The patent implements a feedback control system where sensors detect the orientation of each bulbil before planting. Based on this feedback, the system automatically adjusts the bulbil orientation using electromagnetic actuators to ensure correct upward planting, thereby maintaining high productivity while ensuring proper orientation control.
Solution Approach 2:
The system replaces manual orientation control with an automated electromagnetic control mechanism that uses sensors and actuators to precisely control bulbil orientation, achieving both high productivity and accurate orientation control simultaneously.
3Productivity
If mechanical garlic sowing is used without directional control, then labor intensity is reduced, but the sowing quality and accuracy are poor
Solution Approach 1:
The patent employs sensors to detect bulbil orientation and provides feedback to the control system. Based on this feedback, electromagnetic actuators automatically adjust the orientation to ensure accurate upward planting, achieving both high labor efficiency and high sowing accuracy.
Solution Approach 2:
The system replaces simple mechanical sowing with an automated electromechanical system that uses sensors and electromagnetic actuators to precisely control bulbil orientation, simultaneously improving labor efficiency and sowing accuracy.
4Manufacturing precision
If a complex directional control mechanism is added, then sowing accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical orientation control mechanisms with a simpler electromechanical system using sensors and electromagnetic actuators. This substitution reduces mechanical complexity while achieving precise bulbil orientation control through electronic control and electromagnetic forces.
Solution Approach 2:
The system changes the control parameter from mechanical force to electromagnetic force, allowing for precise orientation control through electrical signals rather than complex mechanical linkages. This parameter change simplifies the overall device structure while maintaining high orientation precision.
