Foldable Traffic Sign Panel With Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid traffic signs are cumbersome, pose safety risks due to their size and weight, obstruct workers' views, consume space, and are prone to damage during construction and maintenance activities.
Innovation Solution
A foldable traffic sign system featuring a rigid sign panel with folding lines and cuts, a telescoping sign stand, and a tote for convenient storage and transport, allowing the sign to be compactly folded and easily carried.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If rigid traffic signs are used to provide clear warning to motorists, then visibility and warning effectiveness are improved, but worker safety deteriorates due to obstruction of view and kite effect in windy conditions
Solution Approach 1:
The sign panel is divided into multiple sections that can be folded along predetermined folding lines, transforming a single large rigid structure into a collapsible configuration that reduces wind resistance and improves worker safety while maintaining visibility when deployed
2Illumination intensity
If large rigid signs are used to ensure adequate warning distance, then motorist notification is improved, but device portability deteriorates due to weight and size
Solution Approach 1:
The sign panel is segmented into foldable sections that can be collapsed into a compact configuration for easy transport and storage, while still providing adequate warning distance when deployed
Solution Approach 2:
The sign structure transitions from a static rigid form to a dynamic foldable design, allowing it to be compact for transport and expanded for deployment, improving portability without sacrificing notification effectiveness
3Strength
If rigid signs are used to maintain structural integrity, then sign durability is improved, but storage efficiency deteriorates due to space consumption
Solution Approach 1:
The sign panel is divided into sections connected by folding lines, allowing the structurally sound design to be collapsed into a compact storage configuration that reduces space requirements while maintaining integrity when deployed
4Object-affected harmful factors
If large rigid signs are used to provide adequate warning, then motorist safety is improved, but susceptibility to damage increases due to bent corners and scratched surfaces
Solution Approach 1:
The sign panel is segmented into foldable sections that can be collapsed to protect the reflective surface from damage during storage and transport, while still providing adequate warning when deployed
Solution Approach 2:
The sign transitions from a vulnerable static rigid structure to a dynamic foldable design that can be protected during storage by collapsing the panels, reducing susceptibility to damage while maintaining motorist safety when in use

AI summary
A foldable traffic sign system comprises a relatively rigid sign panel and a plurality of folding lines disposed in the sign panel, for permitting ready folding of the sign panel into a substantially smaller configuration. In a preferred embodiment, at least one cut is disposed partially along a dimension of the sign panel, to further facilitate ready folding of the sign panel. One of the folding lines is disposed substantially horizontally across a center region of the sign panel, and at least one of the folding lines is disposed substantially vertically on the sign panel, and intersects with the horizontal folding line. The plurality of folding lines creates a plurality of sign sections, preferably six, defined by a combination of the folding lines and cuts in the sign panel. The sign system further comprises a folding sign stand, and a tote for containing both the sign panel and sign stand.
