Autonomous Compactor Override for Surface Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous compactor machines may over- or under-compact surface materials due to uniform compaction settings, affecting the strength, stability, and usability of the surface for construction operations, especially when encountering varying surface conditions.
Innovation Solution
An autonomous machine control system that allows for the initiation of an autonomous mode with automatic control of propulsion, steering, and work operations, enabling human operators to disable automatic work control while maintaining automatic propulsion and steering, allowing for manual override and adjustment of work operations based on surface conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous mode provides automatic control of work operation, then productivity is improved, but manufacturing precision deteriorates due to inability to adapt to varying surface conditions
Solution Approach 1:
The control system is segmented into multiple independent control modes (autonomous mode and manual mode) that can be selectively activated. The controller can switch between automatic control and manual control of work operations, allowing the system to maintain high productivity through autonomous operation while enabling precise manual intervention when surface conditions require adaptation beyond predefined parameters.
2Extent of automation
If autonomous mode provides automatic control of work operation, then human resources are reduced, but adaptability deteriorates due to fixed compaction settings
Solution Approach 1:
The control system transitions from a static, fixed-state autonomous mode to a dynamic system that can adapt its control characteristics in real-time. The controller dynamically switches between autonomous and manual control modes based on operational needs, enabling the system to maintain high automation levels for routine operations while providing adaptability when encountering varying surface conditions that require human judgment.
3Ease of operation
If uniform compaction settings are used, then ease of operation is improved, but manufacturing precision deteriorates due to over- or under-compaction
Solution Approach 1:
The autonomous control system provides self-service through automatic control of work operations based on predefined parameters, eliminating the need for continuous human monitoring and adjustment during normal operations. This maintains ease of operation while incorporating feedback mechanisms and manual override capabilities that enable precise intervention when surface conditions deviate from expectations, thus maintaining compaction quality.

AI summary
An autonomous machine control system is disclosed. The autonomous machine control system may include a controller configured to: cause an initiation of an autonomous mode of a machine, the autonomous mode providing automatic control of a propulsion operation, a steering operation, and a work operation of the machine; determine that automatic control of the work operation is to be disabled in the autonomous mode of the machine; and cause automatic control of the work operation to be disabled in the autonomous mode of the machine, while automatic control of the propulsion operation and the steering operation is enabled in the autonomous mode of the machine.
