Machine Control Scheme Confirmation Before Operator Start-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of machines like excavators may not be aware of the current control scheme, leading to unexpected machine operations and potential dangers or inefficiencies, as existing display systems do not effectively convey control schemes before operation begins.
Innovation Solution
A control scheme confirmation screen is displayed on the machine's interface, visually depicting the current control scheme and allowing operators to confirm and optionally adjust it, ensuring awareness before active operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the machine allows operators to change control schemes, then the adaptability of the machine is improved, but the operator's awareness of the current control scheme deteriorates
Solution Approach 1:
The system displays the current control scheme to the operator before the operator begins operating the machine. This preliminary display ensures the operator is informed of the active control scheme prior to usage, preventing confusion while maintaining the ability to switch schemes.
Solution Approach 2:
The system provides continuous feedback to the operator about which control scheme is currently active. This feedback mechanism ensures the operator remains aware of the control scheme being used, even when changes are possible, by displaying the current configuration state.
2Ease of operation
If the operator learns the control scheme through trial and error, then the operator gains understanding of the control scheme, but the time required to become productive increases
Solution Approach 1:
The control scheme is displayed to the operator before operation begins, providing advance knowledge of how the controls will function. This eliminates the need for trial-and-error learning during actual operation, reducing the time required to become productive.
Solution Approach 2:
The display system acts as an intermediary between the control scheme configuration and the operator. It translates the abstract control scheme settings into visible, understandable information that the operator can review before using the controls, facilitating quicker comprehension.
3Productivity
If the operator begins operating the machine without knowing the control scheme, then the operator can start work immediately, but the safety and efficiency of operations deteriorates
Solution Approach 1:
The system requires the operator to view and acknowledge the current control scheme before operation is permitted. This preliminary step ensures safety and efficiency are maintained while still allowing the operator to begin work promptly after a simple confirmation action.
Solution Approach 2:
The system prevents operation until the operator has been informed of the control scheme, acting as a protective measure against unsafe operation. This preliminary anti-action blocks potentially harmful operation until the operator is properly informed, then allows operation to proceed.

AI summary
A customizable control scheme determines operations of a machine or attached implements that result from usage of machine controls by an operator. A display of the machine presents a control scheme confirmation screen in response to the machine turning on, a new implement being attached to the machine, or another trigger condition. An operator can learn the control scheme that the machine is currently configured to use via the control scheme confirmation screen, and provide user input confirming that the operator is aware of the control scheme that the machine is currently configured to use prior to beginning active operations of the machine following the trigger condition.
