Agricultural Vehicle Control Element Display for Functionality Change Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of agricultural vehicles may forget that the functionality of vehicle control elements has been altered, leading to a lack of verification using the terminal display.
Innovation Solution
Incorporating a vehicle control display element on each control element that indicates whether its functionality has been altered, with a unique color change when functionality is reassigned, allowing operators to easily identify changes by checking the display associated with the control element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the terminal display is used to indicate functionality changes, then the operator can see altered functionality, but the operator may still forget to check the terminal display
Solution Approach 1:
The indication system is segmented into two parts: a primary indication on the control element itself (display element 12, 14, 16, 18) and a secondary detailed indication on the terminal display 20. This segmentation ensures that critical functionality change information is always visible at the point of operation, eliminating the need for operators to separately check the terminal display.
Solution Approach 2:
The display elements 12, 14, 16, 18 act as intermediaries between the control elements and the terminal display 20. They provide immediate visual feedback about functionality changes directly at the control element location, serving as a local indicator that prevents information loss without requiring operators to interact with the terminal display.
2Loss of information
If the operator must check the terminal display to verify functionality changes, then complete information is available, but this increases the time and complexity of operation
Solution Approach 1:
The display elements 12, 14, 16, 18 provide preliminary indication of functionality changes directly on the control elements before the operator needs to verify anything. This preliminary visual feedback is continuously available, so operators can immediately see if a functionality change has occurred without needing to spend time checking the terminal display 20.
3Ease of manufacture
If color-coded hydraulic connections are used, then initial functionality is clearly indicated, but altered functionality is not easily distinguishable
Solution Approach 1:
The system uses color changes in the display elements 12, 14, 16, 18 to indicate altered functionality. When a control element's functionality is changed via the terminal display 20, the associated display element changes color or illumination state to alert the operator that a functionality alteration has occurred, building upon the existing color-coded hydraulic connection system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures operators can quickly determine if functionality changes have occurred, reducing the need for constant terminal display checks and enhancing operational safety by providing visual feedback on control element changes.
