Autonomous Dump Path Control for Uniform Material Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for material dumping in dump areas often result in uneven filling, as they rely on predetermined dump locations rather than adaptive density management, leading to inefficiencies and suboptimal filling patterns.
Innovation Solution
A management unit that uses sensor arrangements on autonomous dump machines to determine environmental parameters, allowing for dynamic adjustment of dump paths and positions to achieve a predetermined dumping density range, ensuring more efficient and dense filling of the dump area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If predetermined dump locations are used, then the dumping operation is simple to plan, but the dump area is not filled in a desired manner (uneven filling)
Solution Approach 1:
The sensor arrangement continuously measures the actual dumping density in the dump area and feeds this information back to the management unit. The management unit compares the measured density with the target density and dynamically adjusts the dump paths and dumping positions to achieve uniform filling, resolving the contradiction between simple planning and filling precision.
Solution Approach 2:
The system transitions from static predetermined dump locations to dynamic dump paths that are continuously adjusted based on real-time sensor measurements of dumping density. The dump paths are adapted during operation to ensure uniform material distribution, achieving precise filling without excessive system complexity.
2Manufacturing precision
If sensor-based adaptive positioning is implemented, then dumping density control is improved, but the device complexity increases
Solution Approach 1:
Sensor arrangements on autonomous dump machines measure environmental parameters and dumping density in real-time, providing feedback to the management unit. This enables precise control of dumping density while keeping the system architecture relatively simple through centralized management and standardized sensor integration.
Solution Approach 2:
The autonomous dump machines independently use their own sensor arrangements to determine when they have reached appropriate dumping positions based on real-time density measurements, reducing the need for complex external control infrastructure while maintaining precise dumping density control.
3Manufacturing precision
If real-time sensor monitoring is used, then dumping position accuracy is improved, but the use of energy increases
Solution Approach 1:
The sensor arrangements monitor only the critical parameters needed for dumping position determination (such as dumping density and environmental features along the dump path) rather than continuously monitoring all possible parameters. This partial monitoring approach maintains dumping position accuracy while reducing energy consumption compared to comprehensive real-time monitoring.

AI summary
A management unit for managing material dumping in a dump area using a plurality of autonomous dump machines. Each autonomous dump machine comprises a sensor arrangement adapted to determine at least one sensor arrangement parameter indicative of the environment adjacent to at least a portion of the autonomous dump machine. The management unit is adapted to establish a set of dump paths, comprising at least one dump path, wherein each dump path extends in the dump area, and issue an instruction to an autonomous dump machine of the plurality of autonomous dump machines to follow a dump path of the set of dump paths until the sensor arrangement parameter, determined by the sensor arrangement of the autonomous dump machine, indicates that the autonomous dump machine has reached a dumping position indicative of a dumping density of the dump area being within a predetermined dumping density range.
