Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional towing vehicles are used without computer control, then the device complexity is low, but the positioning precision of attachments deteriorates on uneven terrain
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated computer control system that uses satellite antennas for location detection and hydraulic systems for attachment adjustment. This substitution of mechanical control with electronic automation resolves the contradiction by achieving high positioning precision through GPS coordinates while managing device complexity through integrated control algorithms.
Solution Approach 2:
The computer control system automatically adjusts attachment positions based on satellite positioning data without requiring continuous manual intervention. The system self-regulates the hydraulic actuators to maintain precise positioning on uneven terrain, enabling the equipment to serve itself in maintaining accuracy while reducing the operational burden.
2Productivity
If attachments are not precisely positioned, then the ease of operation is high, but the productivity and environmental safety deteriorate due to waste and pollution
Solution Approach 1:
The system continuously receives feedback from satellite antennas regarding the actual position of the towing vehicle and attachment. The computer control processes this feedback data and automatically adjusts hydraulic actuators to maintain precise positioning along target lines. This closed-loop feedback mechanism ensures high productivity through accurate fertilizer and weed killer application while managing operational complexity through automated control.
Solution Approach 2:
The system pre-calculates and stores target position lines for the attachment based on the field layout and crop requirements. Before actual operation begins, the computer control has the ideal trajectory prepared, allowing the attachment to follow predetermined precise paths during implementation, thereby maximizing productivity and minimizing waste.
3Loss of substance
If manual positioning is used, then the device complexity is low, but the loss of substance increases due to imprecise application of fertilizers and weed killers
Solution Approach 1:
The patent replaces manual positioning with satellite-based GPS navigation and computer-controlled hydraulic positioning. This substitution enables precise application of fertilizers and weed killers along predetermined target lines, significantly reducing substance loss through accurate delivery to intended locations while managing the added device complexity through integrated control systems.
Solution Approach 2:
The computer control system pre-defines target position lines and application zones before operation. By having the ideal trajectory and dispensing points predetermined, the system ensures that fertilizers and weed killers are applied only where needed, preventing waste and environmental pollution while maintaining manageable operational complexity through automated execution.
