Tool Bar Down Lighting for Low-Light Tool-to-Soil Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural implements, such as tillage and seeding tools, face difficulties in low light conditions, leading to reduced visibility for operators and impaired accuracy of optical sensors, as existing illumination systems do not provide adequate under-bar illumination and are not controllable from the operator's compartment.
Innovation Solution
A system with low-voltage illumination devices powered by both the towing vehicle and a power supply on the implement, providing even illumination of the tool-to-soil interface, which can be controlled individually or in groups from the operator compartment, and includes a display to manage the illumination devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If illumination devices are added to the implement, then operator visibility in low light conditions is improved, but power system load increases
Solution Approach 1:
The illumination system is segmented into multiple individual illumination devices distributed along the implement, allowing selective activation of only the lighting zones needed for current operational requirements, thereby reducing overall power consumption while maintaining visibility where required
Solution Approach 2:
The illumination system incorporates dynamic control capabilities, allowing the operator to adjust which illumination devices are active based on real-time operational needs, enabling the system to adapt power consumption to actual visibility requirements rather than operating at fixed maximum load
2Illumination intensity
If multiple illumination devices are installed on the implement, then under-bar illumination is improved, but device complexity increases
Solution Approach 1:
The illumination devices are designed with universal mounting configurations and standardized electrical connections that allow them to be installed and controlled through existing implement infrastructure, reducing the additional complexity introduced by multiple lighting units
Solution Approach 2:
Multiple illumination devices are electrically connected in groups or circuits that can be controlled collectively through a single interface, and mechanically mounted using shared support structures, thereby reducing control and installation complexity despite having multiple individual lighting elements
3Ease of operation
If illumination devices are made controllable from operator compartment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A control interface is provided in the operator compartment that serves as an intermediary between the operator and the illumination devices, allowing centralized control of multiple lighting units through a single panel or display without requiring direct connection to each device
Solution Approach 2:
The control interface in the operator compartment is designed to control multiple illumination devices through a unified system, allowing a single control mechanism to manage multiple lighting zones, thereby reducing the number of separate controls needed
