Work Vehicle Switch Lighting for Functional Button Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In push button switch systems for working vehicles, multiple light sources are collectively controlled, making it difficult for operators to distinguish between functional and unfunctional switches, leading to reduced convenience.
Innovation Solution
A switch device with light emitting parts that can be switched between turned-on and turned-off states, allowing operators to visually differentiate functional and unfunctional switches through distinct lighting states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If all push buttons are equipped with light sources and collectively controlled, then the illumination intensity is sufficient, but the operator cannot distinguish between functional and unfunctional switches
Solution Approach 1:
The patent divides the collective light control into individual light sources for each push button. Each light source can be independently controlled to illuminate only the necessary functional switches, rather than illuminating all switches collectively. This segmentation allows the operator to clearly distinguish which switches are functional and which are not, resolving the information loss problem while maintaining sufficient illumination intensity for each individual switch.
2Loss of information
If multiple light sources are individually controlled, then switch status is clearly indicated, but the device complexity increases
Solution Approach 1:
The control system automatically determines which push buttons are functional and controls the corresponding light sources without requiring manual intervention. The system self-identifies functional switches based on their connection status and automatically illuminates only those switches that are currently functional, reducing the operational complexity while maintaining clear status indication.

AI summary
A switch device for a work vehicle comprises a plurality of switches and light-emitting sections. The plurality of switches are used in the operation of a work vehicle. Each light-emitting section corresponds to at least some switches from among the plurality of switches. Each light-emitting section corresponding to some of the switches is configured to be capable of switching between a lighted state and a non-lighted state.
