Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicles face challenges with visibility due to environmental conditions and limited mounting space for lighting systems, leading to reduced light output and mounting apparatus strain.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If more lighting modules are added to increase light output, then visibility is improved, but the weight and strain on the mounting apparatus increases
Solution Approach 1:
The patent implements dynamic control of lighting modules through a controller that receives sensor inputs and adjusts the operation of LED modules accordingly. The system can dynamically switch between different lighting modes (e.g., high beam, low beam, fog light modes) and adjust intensity levels, allowing the full lighting capability to be available when needed while operating at reduced weight-equivalent capacity during normal conditions. This dynamic adjustment effectively resolves the contradiction by making the lighting system's functional weight variable rather than fixed.
2Illumination intensity
If more lighting modules are mounted to increase light output, then visibility is improved, but the mounting space required increases
Solution Approach 1:
The patent designs lighting modules that can perform multiple functions through electronic control. A single physical mounting location can support modules that provide different lighting functions (high beam, low beam, fog lights, turn signals) by activating different LED groups within the same module. This multi-functionality allows the system to achieve diverse light output capabilities without proportionally increasing the number of physical mounting locations required, effectively resolving the space constraint contradiction.
3Adaptability or versatility
If lighting system size is increased to provide more signaling options, then vehicle operation signaling capability is improved, but the strain on the mounting apparatus increases
Solution Approach 1:
The patent implements dynamic control of lighting modules through a controller that receives sensor inputs and adjusts the operation of LED modules accordingly. The system can dynamically switch between different lighting modes (e.g., high beam, low beam, fog light modes) and adjust intensity levels, allowing the full lighting capability to be available when needed while operating at reduced weight-equivalent capacity during normal conditions. This dynamic adjustment effectively resolves the contradiction by making the lighting system's functional weight variable rather than fixed.

AI summary
A lighting device is provided for controlling the photometric distribution of light emitted by two or more LEDs. The lighting device may be integrated with a control system of the vehicle and may be controlled by a remote controller. The lighting device may be capable of being operated in one or more modes of operation based on operating conditions, user input, or both. Operating conditions may include vehicle conditions, environmental conditions, and user conditions. The controller may operate a software application to enable the user to modify, control, or otherwise regulate any mode of operation or other feature of the lighting system.
