Agricultural Lighting Switching Between Road and Field Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural working machines face challenges in providing adequate lighting for both road travel and work environments while meeting legal requirements, with existing solutions either being ineffective for public roads or not permitted due to dazzling issues.
Innovation Solution
An agricultural working machine equipped with dual lighting devices that can switch between road travel and work lighting modes, using reflectors and adjustable light sources to ensure compliance with legal standards and improve visibility without dazzling other road users, with automatic mode switching based on the machine's position using a navigation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If powerful lamps are mounted on the machine to improve illumination of the working area, then visibility is improved, but the lamps are not approved for use on public roads due to glare
Solution Approach 1:
The patent applies dynamics by making the lighting system adjustable and switchable between different operating modes. The lighting device can be switched between a first operating mode for road travel with restricted light distribution and a second operating mode for field work with enhanced illumination, allowing the system to adapt to different operational contexts and eliminate glare on public roads while providing powerful illumination during field work
Solution Approach 2:
The patent changes the parameters of the lighting system by adjusting the light distribution pattern and intensity based on the operating context. The lighting device can modify its beam pattern, range, and intensity to comply with road traffic regulations during public road use while providing maximum illumination during field operations, thus resolving the contradiction between illumination needs and glare prevention
2Adaptability or versatility
If separate lighting systems are provided for road travel and field work, then lighting needs are met, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a single lighting device that can perform multiple functions - serving both as a road travel lighting system compliant with traffic regulations and as a field work illumination system. The device includes switchable operating modes that allow it to adapt to different operational requirements, eliminating the need for separate lighting systems for road and field operations
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 safety and reduces operator workload by providing improved illumination in various conditions, meeting changing lighting needs while adhering to legal regulations, and increasing traffic safety.
Implementation Method 1
The lighting devices have light sources (34) for generating the light and emit the light at least partially directed towards the surroundings of the machine
Implementation Method 2
A translucent element protects the light source and reflector from external elements such as moisture, dirt, or foreign objects, sealing the lighting unit. This type of lighting system directs the light generated by the light source towards the area in front of the machinery
