Movable Road Signage Assembly for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current road signaling systems on vehicles, particularly during lane changes, pose a risk of collision due to the fixed position of signaling assemblies, which do not adequately account for the passage of passenger vehicles, leading to potential collisions and increased shock absorption by the vehicle itself.
Innovation Solution
A road signaling system with a movable upper luminous display assembly that can tilt and translate laterally, allowing it to project outside the vehicle's width, ensuring that passenger vehicles can pass underneath without collision and distributing shock to a lighter, openwork frame structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the signaling assembly is positioned within the gauge of the road vehicle, then the structural stability and ease of mounting are improved, but the risk of collision with passenger vehicles increases
Solution Approach 1:
The signaling assembly is divided into two independent parts: a first part that remains fixed within the vehicle gauge and a second part that can translate laterally outside the gauge. This segmentation allows each part to serve its specific function - the first part provides structural stability while the second part reduces collision risk with passenger vehicles.
Solution Approach 2:
The second part of the signaling assembly is made movable rather than fixed, allowing it to translate laterally between a retracted position (within gauge) and an extended position (outside gauge). This dynamic capability enables the assembly to adapt its position based on operational needs, reducing collisions while maintaining structural integrity.
2Adaptability or versatility
If the upper section is folded forward to reduce lateral profile, then the transportability is improved, but the signaling visibility is reduced
Solution Approach 1:
The signaling assembly is segmented into an upper section and a lower section, with the upper section capable of folding forward during transport while the lower section remains stationary and maintains visibility. This segmentation allows the system to optimize for transportability without completely compromising signaling capability.
Solution Approach 2:
The upper section is designed to be dynamically foldable between a vertical signaling position (for visibility) and a folded-forward transport position (for reduced lateral profile). This dynamic adjustment allows the system to adapt its configuration based on whether it is in operation or transport mode.

AI summary
Disclosed is a traffic signage system (1) on a roadwork vehicle (7) having a defined width, said system (1) comprising two main display assemblies (2, 3) (5, 6), i.e. a first assembly (2, 3) consisting of road signs and a second assembly (5, 6) consisting of a luminous display, the first assembly (2, 3) being confined within the width of the vehicle (7) and comprising a stationary vertical lower section (2) and an upper section (3) that can pivot along a horizontal transverse axis between a deployed position, in which the upper section (3) extends vertically from and parallel to the lower section (2), and a retracted position, in which the upper section (3) is folded in the direction of the front and tilted in relation to the plane of the lower section (2). According to the invention, the second assembly (5, 6) includes a first, stationary portion (6) that is secured to the lower section (2) as well as a second portion (5) that is secured to the upper section (2), the first, stationary portion (6) being disposed substantially towards the top of the lower section (2) and parallel to the upper edge thereof (2), the second portion (5) being horizontally laterally translatable parallel to the plane of the upper section (3) in order to be able to laterally protrude beyond the width of the vehicle (7), between a neutral position in which the second portion (5) is disposed so as to face the upper section (3) within the width of the vehicle (7), and a laterally protruding position in which the second portion (5) laterally protrudes beyond the width of the vehicle (7).
