Angled Guide Post Assembly with Segmented LED Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighted guide post systems for boat trailers have limitations in visibility, particularly in low-light conditions, and do not comply with regulatory requirements regarding lighting colors and placement, leading to difficulties in centering boats and ensuring rear visibility.
Innovation Solution
A lighted guide post assembly with angled support posts and translucent circular tubes, featuring LED light strips that provide continuous lighting along the length of the posts, using red and amber lights to differentiate rear and side views, and are integrated with the trailer's lighting system to prevent color bleeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If lights are positioned only at the top of guide posts, then the structure is simple, but visibility between guide post lights and trailer tail lights is limited and rear visibility is reduced
Solution Approach 1:
The lighting system is segmented into multiple sections: top lights, intermediate lights, and bottom lights positioned at regular intervals along the guide post. This segmentation provides comprehensive visibility along the entire length of the guide post while maintaining a modular, manageable structure that complies with regulatory requirements
Solution Approach 2:
The lighting arrangement transitions from a single-point illumination at the top to a distributed three-dimensional arrangement along the vertical length of the guide post. This dimensional expansion ensures visibility from multiple angles and distances, addressing both boater guidance and road safety requirements
2Loss of information
If multiple colors of lights are used to provide different information, then information communication is improved, but color bleeding between adjacent lights occurs
Solution Approach 1:
The color separation function is extracted and assigned to a dedicated physical component: a translucent barrier positioned between adjacent light sources. This barrier selectively transmits specific wavelengths while blocking others, preventing color bleeding and ensuring clear communication of different information signals
Solution Approach 2:
A translucent barrier acts as an intermediary element between multiple colored light sources. This intermediate component mediates the interaction between different color lights, allowing each color to communicate its information clearly without interference from adjacent colors
3Illumination intensity
If guide post lights are positioned at the top only, then the structure is simple, but rear visibility for drivers trailering boats is limited
Solution Approach 1:
The lighting system is divided into multiple vertical segments along the guide post, with lights positioned at the top, intermediate levels, and bottom. This segmentation ensures that rear-facing lights are distributed throughout the vertical space, providing comprehensive rear visibility for drivers while maintaining a structured, regulatory-compliant arrangement
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 visibility and compliance with regulations by providing comprehensive lighting throughout the guide posts without color bleeding, improving boat centering and rear visibility, especially in low-light conditions.
Implementation Method 1
LED light strips that provide continuous lighting along the length of the posts
Implementation Method 2
translucent circular tubes, featuring LED light strips that provide continuous lighting along the length of the posts

AI summary
A lighted guide post assembly for a boat trailer is provided. The assembly includes a square tubular angled support post that attaches to a boat trailer, a translucent circular outer tube that covers the square support post, and strips of lights that suspend within the interior of the outer tube between the outer tube and the square support post. This arrangement allows the guide post to glow on four sides without light bleeding together from adjacent sides of the guide post.
