Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coordinating and controlling the operation of multiple mobile machines in road working, construction, and mining operations, especially at night, is challenging due to the need for precise illumination adjustments to prevent glare and ensure safe and efficient interaction between machines.
Innovation Solution
An illumination control system that includes a positioning/location device and an electronic controller on one mobile machine to determine the proximity of other machines and adjust illumination lamps accordingly, ensuring optimal lighting levels based on the distance between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If illumination lamps are used to improve visibility during night operations, then visibility is improved, but glare may be generated that affects operator safety and comfort
Solution Approach 1:
The illumination control system dynamically adjusts the intensity of illumination lamps based on the real-time proximity of other mobile machines. When another machine approaches within a predetermined distance, the system automatically reduces the illumination intensity to prevent glare, and restores full intensity when the other machine is beyond the threshold distance, thereby adaptively resolving the contradiction between visibility and glare prevention.
Solution Approach 2:
The system employs a positioning device to continuously monitor the location of other mobile machines and provides feedback to the electronic controller. Based on this feedback regarding the distance between machines, the controller automatically adjusts illumination lamp intensity, creating a closed-loop control system that resolves the visibility-glare contradiction through real-time environmental awareness and adaptive response.
2Productivity
If multiple mobile machines operate in close proximity to cooperatively complete operations, then operational efficiency is improved, but coordination and control difficulty increases
Solution Approach 1:
The positioning device continuously provides feedback on the relative positions of multiple mobile machines to their respective electronic controllers. This enables automatic coordination where each machine's illumination and operational parameters are adjusted based on real-time spatial relationships, reducing the complexity of manual coordination and enabling efficient multi-machine operations.
Solution Approach 2:
Each mobile machine is equipped with an autonomous illumination control system that automatically adjusts its own illumination based on the proximity of other machines. This self-service capability eliminates the need for complex centralized control systems, allowing multiple machines to coordinate efficiently through individual autonomous decision-making based on shared spatial awareness.

AI summary
An illumination control system for a mobile machine that operates in coordination with other mobile machines is configured to adjust an illumination lamp disposed on the mobile machine and directed in a travel direction of the machine. The illumination control system includes a positioning/location device that can determine a proximity distance between the mobile machine and a second mobile machine approaching in the travel direction. The illumination control system also includes an electronic controller configured to adjust the illumination device based on the proximity distance as determined. The illumination control system may find particular usefulness in paving and/or milling operations.
