Semi-Autonomous Controller for Industrial Machine Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial machines, such as mining shovels, require precise control for operations like digging and hoisting, but existing autonomous systems often necessitate user intervention for stalling conditions or object contact, leading to inefficient restarts.
Innovation Solution
A controller system that receives signals from operator controls to control movable components, enabling autonomous operations and adjusting these operations based on further input, allowing for seamless transition between manual and semi-autonomous modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous operations are implemented to maximize efficiency, then productivity is improved, but user intervention is still required for stalling conditions and object contact
Solution Approach 1:
The system continuously monitors operational parameters and automatically adjusts autonomous operations in response to detected conditions such as stalling or object contact, eliminating the need for user intervention while maintaining safe and efficient operation
Solution Approach 2:
The autonomous operation system performs self-adjustment and self-correction when encountering operational issues like stalling conditions or object contact, enabling the system to handle its own anomalies without requiring external user input
2Reliability
If user intervention is required for stalling conditions and object contact, then operational safety is improved, but complete restart of operations is necessary
Solution Approach 1:
The system pre-configures adjusted autonomous operations that account for potential stalling conditions and object contact, allowing immediate continuation of modified operations rather than requiring complete restart
Solution Approach 2:
The autonomous operation system dynamically adjusts its parameters and behavior in real-time based on operational conditions, enabling seamless transition and continuation of operations without full restart while maintaining safety
3Manufacturing precision
If precise control is required for digging and hoisting operations, then manufacturing precision is improved, but operational complexity increases
Solution Approach 1:
The system replaces complex manual mechanical control with an autonomous electronic control system that uses sensors, processors, and automated algorithms to achieve precise control of digging and hoisting operations with simpler user interaction

AI summary
A method of operating an industrial machine. The method including controlling, via a controller, a movable component of the industrial machine based on a first signal received from an operator control and controlling, via the controller, the movable component of the industrial machine according to an autonomous operation in response to a second signal. The method further including adjusting the autonomous operation to generate an adjusted autonomous operation in response to receiving a third signal from the operator control and controlling, via the controller, the movable component of the industrial machine according to the adjusted autonomous operation in response to receiving a fourth signal.
