Implement-Positioned Grade Indicator for Focal Distance Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of heavy equipment, such as excavators or dozers, face challenges in maintaining focus on the implement while using GPS-enabled systems for grading, leading to potential safety issues and operator fatigue due to repetitive focus shifts between the implement and the display.
Innovation Solution
A grade-level indicator is positioned in proximity to the implement, allowing the operator to view the indicator at a similar focal distance as the implement, thereby reducing the need to shift focus away from the implement and minimizing fatigue and safety risks.

Engineering Contradiction Analysis
1Loss of information
If the indicator is positioned in the cab display, then the operator can view grading information, but the operator must shift focus between the implement and the display causing fatigue and safety issues
Solution Approach 1:
The indicator is moved from the two-dimensional cab display plane to a three-dimensional position on the implement itself, changing the spatial dimension of information delivery. This allows the indicator to be viewed in the same focal plane as the implement, eliminating the need for focus shifting while maintaining continuous visual contact with the work area.
2Ease of operation
If the indicator is positioned on the implement, then the operator can view information at the same focal distance, but the indicator may be less visible or accessible
Solution Approach 1:
The indicator utilizes color changes (different colored lights) to convey grading status information. This visual differentiation enhances visibility and information communication at the implement location, compensating for the reduced visibility that might result from positioning the indicator away from the protected cab environment.
