Image-Guided Attachment Trajectory Reset for Changing Excavation Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment operation systems in working machines, such as hydraulic excavators, are inefficient due to changes in the excavation target shape or contour during operations, leading to failure in reaching the excavation point and reduced work efficiency.
Innovation Solution
An attachment target locus setting system that includes a target locus setting part, an image capturing device, a finish point shifting part, and a target locus resetting part to dynamically adjust the target locus based on real-time peripheral information, allowing the attachment to efficiently operate by shifting and resetting the target finish point and locus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the attachment operates based on preliminarily taught target posture, then the operation follows a predetermined path, but the excavation point cannot be reached when the ground surface shape changes
Solution Approach 1:
The system captures images of the actual ground surface around the excavation point and uses this visual feedback to detect changes in the ground shape. The detected ground surface information is fed back to dynamically adjust the target locus, ensuring the attachment can reach the actual excavation point even when the ground surface changes during operation.
Solution Approach 2:
The target locus is transformed from a static, preliminarily taught path to a dynamic path that is continuously adjusted based on real-time ground surface conditions. The system dynamically recalculates the target locus by shifting the excavation point coordinates according to the detected ground shape changes, enabling the attachment to adapt its operation path in real-time.
2Productivity
If the target locus is fixed based on preliminary teaching, then the operation path is predetermined, but work efficiency decreases when the excavation point changes
Solution Approach 1:
The system continuously monitors the ground surface around the excavation point using image capture and detects changes in real-time. This feedback mechanism allows the system to identify when the excavation point has shifted due to ground surface changes and immediately adjust the target locus accordingly, preventing time loss from following an outdated path.
Solution Approach 2:
The system automatically detects ground surface changes and autonomously adjusts the target locus without requiring external intervention or manual reprogramming. The automatic recalculation and updating of the excavation point coordinates based on captured images enables the system to self-correct its operation path, maintaining high productivity despite changing conditions.

AI summary
An attachment target locus setting system for efficiently operating an attachment is provided. The system includes a target locus setting part that sets a target locus for a specific portion of the attachment from a target start point being a target point where the attachment starts an operation to a target finish point being a target point where the attachment finishes the operation, an image capturing device that captures a periphery around the target finish point as peripheral information, a finish point shifting part that shifts, on the basis of the peripheral information, the target finish point, and a target locus resetting part that resets the target locus to a target locus in a range from the target start point to a target finish point having been shifted.
