Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tilting and rotating operations are used, then the bucket can be adjusted to some extent, but it requires high skilled skills and is difficult for beginners
Solution Approach 1:
The system performs automatic alignment of the bucket's rotating axis with the work area normal vector without requiring manual intervention for tilting adjustments. The electronic control unit automatically calculates and executes the necessary tilting angle based on the relationship between the bucket's rotating axis and the work area, making the system self-adjusting and eliminating the need for skilled manual operations.
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with an automated electronic control system. The electronic control unit receives signals from operation levers and automatically controls the tilting and rotating actuators, substituting the complex mechanical skill-based manual adjustment with an automated electromechanical system that simplifies operator input while maintaining precise control.
2Manufacturing precision
If the rotating axis of the bucket is not aligned in the work area, then a part of the rear side of the bucket may invade the work area, but arbitrary adjustment requires higher experienced skills
Solution Approach 1:
The system continuously monitors the angular relationship between the bucket's rotating axis and the work area normal vector, and the electronic control unit automatically adjusts the tilting angle based on this feedback. The control system calculates the deviation from proper alignment and executes corrective tilting movements, creating a closed-loop feedback system that ensures precise alignment without requiring operator skill for judgment.
Solution Approach 2:
The automatic alignment system performs self-adjustment by continuously monitoring the bucket's orientation and autonomously executing tilting corrections to maintain proper alignment with the work area. This self-service capability eliminates the need for operators to manually judge and adjust alignment, thereby achieving high precision while simplifying operation.
3Adaptability or versatility
If tilting and rotating actuators are added, then the bucket can tilt and rotate for excavation in narrow spaces, but the device complexity increases
Solution Approach 1:
The patent combines the tilting and rotating functions into a single integrated tilt rotator assembly. The tilting actuator and rotating actuator are merged into one structural unit that operates cooperatively under unified electronic control, allowing the bucket to achieve both tilting and rotating movements while managing system complexity through integration rather than separate independent systems.
Solution Approach 2:
The tilt rotator system provides multiple functions including tilting, rotating, and automatic alignment capabilities within a single integrated mechanism. This multi-functional design enables the bucket to adapt to various excavation scenarios including narrow spaces, while the electronic control unit coordinates all movements through a unified control interface, maximizing versatility without proportionally increasing operational complexity.
