Portable LED Lighting Strip for Trailer Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency lighting systems for tractor trailers do not ensure maximum visibility to oncoming traffic when a truck is stalled, as they may not provide sufficient illumination from a distance, potentially leading to inadequate reaction time for other vehicles.
Innovation Solution
A portable LED lighting strip with a battery-powered source and attachment means, such as eyelets and a magnetic attachment, is placed across the rear panel of a trailer to provide enhanced visibility by illuminating the stalled truck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If hazard lights are used on the truck, then the truck becomes visible to oncoming vehicles, but the visibility distance is insufficient and reaction time is inadequate
Solution Approach 1:
The lighting system is divided into multiple separate LED lights arranged in a specific pattern (three rows of three lights each) across the rear panel. This segmentation allows the light to be distributed over a larger area, increasing the overall visibility distance and providing earlier warning to oncoming traffic.
Solution Approach 2:
The patent utilizes different colored LED lights (red, yellow, green) arranged in specific patterns to enhance visibility. The color variation creates a more noticeable and distinctive visual signal that can be detected from greater distances compared to single-color hazard lights.
2Illumination intensity
If a portable LED lighting strip is placed across the rear panel, then visibility to oncoming traffic is significantly increased, but the device complexity and attachment requirements increase
Solution Approach 1:
The lighting strip incorporates self-contained attachment mechanisms (magnetic attachments or adhesive backing) that allow the device to secure itself to the rear panel without requiring external fastening hardware or complex installation procedures. The battery pack also serves dual purposes as both power source and mounting component.
Solution Approach 2:
The patent combines multiple functions into a single integrated unit: the LED lights, battery pack, attachment mechanisms, and protective housing are merged into one portable lighting strip. This consolidation simplifies the overall device while maintaining enhanced visibility capabilities.
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
The solution significantly increases the visibility of a stalled tractor trailer to oncoming traffic, enhancing safety by providing a bright warning at a greater distance, thus improving reaction time and preventing potential accidents.
Implementation Method 1
A series of LED lights extending across the strip

AI summary
An emergency lighting system that includes: a portable strip adapted for placement across a rear panel of a trailer; a series of LED lights extending across the strip; a means to attach the portable strip to the rear panel; and a power source for the portable strip. The means to attach preferably includes a series of eyelets. The power source is preferably a battery and includes an on and off switch.
