Agricultural Machine Frame Integrated LED Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural working machines with soil tillage tools face challenges in illuminating only the working area effectively at night, leading to energy inefficiency and driver distraction due to strong light reflections from machine frames.
Innovation Solution
Arranging LED light sources within the frame's hollow profile tube elements, positioned below and inside the working area, to illuminate only the soil tillage tools and their working areas, while shielding non-illuminated areas with frame elements, creating a focused and energy-efficient lighting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If powerful headlights are used to illuminate the entire working machine, then the working area becomes visible in the dark, but energy consumption increases and driver vision is obscured by light reflections from frame parts
Solution Approach 1:
The patent applies local quality by positioning light sources specifically at the frame elements adjacent to the working area of the tillage tools. This localized illumination approach ensures that only the relevant working area is lit, avoiding the energy waste of illuminating the entire machine while maintaining adequate visibility for the driver to monitor tool performance.
2Illumination intensity
If powerful headlights are used to illuminate the entire working machine, then the working area becomes visible in the dark, but the driver is distracted by additional illuminated areas of the working machine
Solution Approach 1:
The patent applies local quality by positioning light sources specifically at the frame elements adjacent to the working area of the tillage tools. This localized illumination approach ensures that only the relevant working area is lit, avoiding the energy waste of illuminating the entire machine while maintaining adequate visibility for the driver to monitor tool performance.
3Use of energy by moving object
If light sources are arranged to illuminate only the tillage tools and working area, then energy consumption is reduced and driver focus is improved, but the light sources need integrated attachment to frame elements
Solution Approach 1:
The patent applies merging by integrating the light sources directly into the frame elements of the working machine. The light sources are attached to or incorporated within the existing frame structure, eliminating the need for separate mounting brackets or additional structural components. This integration simplifies the overall device design while achieving the goal of localized illumination.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances visibility of the working area for the tractor driver, reducing energy consumption and minimizing distractions by focusing illumination on the tillage tools' work area, ensuring clear and efficient operation in dark conditions.
Implementation Method 1
A simple configuration of the light source can be achieved in that the light source has light sources designed as LEDs

AI summary
The invention relates to an agricultural working machine comprising soil working tools and a frame. Said soil working tools are arranged on the frame by means of supports, and at least one light source is associated with the machine for at least partially illuminating the work area of said machine. The aim of the invention is to improve, using simple means, the illumination of the work area of soil working tools which can be embodied as seed coulters, tined cultivators etc. in order to make the area visibly clearer and easier to recognise for the driver of the tractor pulling the working machine. According to the invention, at least one light source is arranged in the area of the frame such that only the area of the soil working tools and the work area is illuminated.
