Excavation Point Selection Using Height Data and Track Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing excavation technologies face inefficiencies when the shape of the excavation target changes during the excavation process, as they rely on predetermined scenarios and measurements, which can lead to suboptimal selection of excavation points and increased computational complexity.
Innovation Solution
An excavation point identification apparatus that acquires height information, extracts potential excavation point candidates, infers the excavation amount based on the excavation track, and selects the most suitable point for efficient excavation, using a combination of sensors and data processing to adapt to changing target shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a target track is set based on initial landform information and target excavation volume, then the excavation process can be automated and controlled, but the system cannot adapt when the excavation target shape changes during excavation
Solution Approach 1:
The system dynamically updates the excavation target shape information during the excavation process by continuously acquiring new landform data. The control apparatus recalculates the target track based on the updated excavation target shape, allowing the system to adapt to changes in real-time while maintaining automated control.
Solution Approach 2:
The system incorporates feedback by acquiring updated landform information during excavation and using this information to recalculate the target track. This feedback loop enables the system to adjust to changes in the excavation target shape, ensuring the excavation remains on track even when the target shape changes.
2Productivity
If the excavation area is divided into multiple sites with predetermined candidate positions, then the excavation process can be planned systematically, but the system cannot efficiently handle changes in earth and sand shape during excavation
Solution Approach 1:
The system maintains the systematic approach of dividing the excavation area into multiple sites but dynamically updates the candidate positions within each site based on current landform data. This allows the systematic excavation plan to adapt to changes in earth and sand shape, maintaining both productivity and adaptability.
Solution Approach 2:
The system performs preliminary division of the excavation area into multiple sites and identifies candidate positions in advance. However, it also prepares for changes by having the ability to recalculate candidate positions based on updated landform information, combining preliminary planning with adaptive capability.
3Ease of operation
If a fixed excavation scenario is used, then the excavation process can be simplified and executed efficiently, but the system cannot adapt when the excavation target shape changes
Solution Approach 1:
The system uses a simplified excavation scenario framework but makes it dynamic by automatically updating the target track based on current landform data. This maintains ease of operation while enabling adaptation to shape changes through automated recalculation.
Solution Approach 2:
The control apparatus performs self-service by automatically acquiring updated landform information and recalculating the target track without requiring manual intervention. This maintains the simplicity of operation while enabling the system to adapt to changing excavation target shapes autonomously.

AI summary
Provided is an excavation point identification apparatus which can efficiently carry out excavation even if a shape of an excavation target has changed. An extraction section (12) extracts, with reference to pieces of height information at a plurality of points of an excavation target to be excavated by an excavation apparatus, a plurality of excavation point candidates each of which is a candidate for an excavation point at which the excavation apparatus starts excavation. An inference section (13) infers, based on an excavation track of the excavation apparatus, an excavation amount, in which the excavation apparatus carries out excavation, for each of the plurality of excavation point candidates which have been extracted by the extraction section (12). A selection section (14) selects an excavation point from among the plurality of excavation point candidates based on the excavation amount which has been inferred by the inference section (13).
