Work Vehicle Meter Panel With Lighted Arc Indicators for Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meter panels in agricultural and construction machines struggle with visibility issues as the amount of information displayed increases, making it difficult for operators to obtain necessary information during various outdoor operations.
Innovation Solution
The implementation of a meter panel unit with arc-shaped indicators and facing plates that include light emitting regions, controlled by a controller to display information and change colors or luminance, enhancing visibility and information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If more kinds of information are displayed on the meter panel, then the information completeness is improved, but the visibility decreases
Solution Approach 1:
The meter panel is divided into multiple independent indicator regions, each dedicated to displaying specific information. This segmentation allows multiple types of information to be presented simultaneously in distinct areas, maintaining visibility while improving information completeness.
Solution Approach 2:
The patent introduces a vertical dimension to the display by arranging indicator regions both horizontally and vertically on the meter panel. This multi-dimensional layout increases the display capacity without compromising the visibility of individual indicators, resolving the contradiction between information completeness and visibility.
2Illumination intensity
If arc-shaped indicators with light emitting regions are added, then the visibility is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into integrated components: the arc-shaped indicators serve both as decorative elements and as functional display elements with embedded light emitting regions. The facing plates are integrated with the meter panel structure, reducing overall complexity while achieving improved visibility.
Solution Approach 2:
The light emitting regions in the arc-shaped indicators can change color to indicate different states or information types. This color-changing capability provides enhanced visibility and information differentiation without requiring separate physical indicators for each state, thereby managing device complexity.
