Tilt Bucket Surface Selection for Faster Design-Surface Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The control of a tilt bucket in construction machines can lead to reduced work efficiency when it takes time to align with target design surfaces, affecting the tracking precision and overall operation efficiency.
Innovation Solution
A control system that determines a control object surface based on the distances between the tilt bucket and adjacent design surfaces, controlling the tilt axis of the bucket to maintain alignment with the control object surface, and using distinct display modes to guide the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the tilt bucket is controlled to track the first design surface, then the alignment precision with the target surface is improved, but the time required to bring the tilt bucket close to the surface increases, reducing work efficiency
Solution Approach 1:
The control system determines the control object surface in advance based on the current position of the tilt bucket and multiple design surfaces. By pre-selecting which surface to track before the bucket arrives, the system prepares the optimal alignment target, reducing the time needed for precise alignment when the bucket reaches the vicinity of the construction area.
Solution Approach 2:
The control object surface is dynamically determined based on the real-time position of the tilt bucket. The system continuously evaluates distances to multiple design surfaces and switches the control target accordingly, allowing the bucket to efficiently approach different surfaces without manual intervention, thus maintaining both speed and precision.
2Ease of operation
If the driver manually operates the operating device to bring the tilt bucket close to the design surface, then the alignment can be achieved, but the operation time increases and work efficiency decreases
Solution Approach 1:
The control system automatically determines the control object surface and controls the tilt bucket's movement without requiring continuous manual operation. The system serves itself by autonomously selecting the target surface and adjusting the bucket position, freeing the driver from time-consuming manual adjustments while maintaining alignment capability.
Solution Approach 2:
The system continuously monitors the position of the tilt bucket relative to multiple design surfaces and uses this feedback to automatically adjust the control object surface selection. This closed-loop control enables the system to respond dynamically to changing positions, reducing the time needed for manual intervention while maintaining precise alignment.

AI summary
A control system of a construction machine comprises: a determination unit that determines a control object surface from a first design surface and a second design surface adjacent to the first design surface on the basis of a distance between a tilt bucket and the first design surface and a distance between the tilt bucket and the second design surface; a working equipment control unit that controls a tilt axis of the tilt bucket on the basis of the control object surface determined by the determination unit; and a display control unit that causes a display device to use different display modes to display the control object surface and a surface other than the control object surface.
