Integrated Lighting Device for Construction Machine Control Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional external control stations for construction machines, such as road finishers, require auxiliary lights that are cumbersome and prone to dirt accumulation when used via external sockets, hindering operation in low-light conditions.
Innovation Solution
An integrated lighting device within the outside control station, utilizing LEDs and a translucent cover for protection, allows for self-contained illumination without external power sources, with adjustable orientation and brightness, and optional automatic activation via light sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If auxiliary lights are used via external sockets or terminals, then illumination of the operating area is provided, but the sockets get dirty and additional lights must be carried or held
Solution Approach 1:
The lighting device is integrated directly into the housing of the outside control station, merging the illumination function with the control station structure. This eliminates the need for separate auxiliary lights and external sockets, resolving the issue of dirt accumulation on sockets while providing reliable illumination.
2Illumination intensity
If auxiliary lights are used via external sockets, then illumination is provided, but additional equipment must be carried or held which impairs handling
Solution Approach 1:
The lighting device is integrated directly into the housing of the outside control station, merging the illumination function with the control station structure. This eliminates the need for separate auxiliary lights that would need to be carried or held, thereby maintaining ease of operation.
3Reliability
If a transparent cover is provided for the lighting device, then protection from dust and water is achieved, but the cover material must be translucent to maintain lighting effect
Solution Approach 1:
The cover is designed with specific local properties: it is transparent or translucent in the regions where light transmission is needed, while maintaining protective qualities. This allows the cover to simultaneously protect the lighting device from environmental influences while ensuring adequate light transmission for effective illumination.
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
Enhances operational safety and maintainability by providing stable, directed illumination without additional equipment or distractions, ensuring effective use in dark environments without impairing handling.
Implementation Method 1
An individual LED or an array of LEDs, for example, are suitable as illuminants for the lighting device
Implementation Method 2
The cover is translucent, so that the effect of the lighting device is ensured
