Nested Hollow Paddles for Highway Glare Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glare screen systems for highways are cumbersome to install and perform poorly under impact due to their stiff materials, leading to safety concerns from driver disorientation and temporary blindness caused by oncoming vehicle headlights.
Innovation Solution
A glare screen system comprising nested, tapered, and hollow paddles integrated with a horizontal rail, featuring a receiver and attachment portion for easy assembly and impact absorption, made from a flexible plastic material to enhance safety and installation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If stiff materials are used to make glare screen panels, then the panels can effectively block glare, but the panels perform poorly when impacted and may be ripped off or cause dangerous high-impact force
Solution Approach 1:
The patent replaces traditional stiff panels with flexible hollow paddles that can bend and deform under impact. The paddles are made of flexible material that allows them to absorb impact energy through deformation rather than rigid resistance, preventing both panel failure and dangerous force transmission while maintaining glare blocking functionality through their tapered geometry and arrangement
Solution Approach 2:
The patent changes the physical parameters of the glare screen elements by using hollow tapered paddles instead of solid rigid panels. The hollow construction reduces weight and increases flexibility, while the tapered shape optimizes both glare blocking and impact absorption characteristics, allowing the structure to adapt to impact forces
2Strength
If traditional bolted brackets are used to attach panels to horizontal rails, then the panels can be securely mounted, but the system becomes cumbersome to assemble and install
Solution Approach 1:
The patent combines multiple components into integrated units where the hollow paddles are formed as single pieces with built-in attachment features. The receiver portions and attachment portions are integrated into the paddle structure itself, eliminating the need for separate brackets and bolts, thereby simplifying installation while maintaining secure mounting through the interlocking unit design
Solution Approach 2:
The patent employs a nested modular design where glare screen units with hollow paddles can be stacked and interconnected through receiver and attachment portions. This nesting approach allows for easy assembly and disassembly of multiple units while maintaining structural integrity, as each unit can be independently handled and connected to form the complete glare screen system
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 system effectively blocks glare while being easy to install and absorb impact, reducing the risk of accidents and providing a safer, more durable solution for highway glare management.
Implementation Method 1
The panels will either be ripped off their connections with the horizontal rail, or the panels will provide no give, resulting in a dangerous high-impact force

AI summary
A glare screen system comprises a number of glare screen units arranged in an end-to-end manner. Each glare screen unit comprises a number of upright paddles integrally formed with a horizontal rail. The paddles are tapered and hollow, allowing the glare screen unit to be nested on top of another one of the glare screen units. In addition, each glare screen unit comprises a receiver portion and an attachment portion at opposite ends. The receiver portion of one unit is configured to engage with the attachment portion of another unit to form the glare screen system.
