Reconfigurable Reflective Road Marker for Adaptive Traffic Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reflective road and driveway markers lack the ability to be reconfigured to optimize reflector orientation based on traffic direction, limiting their visibility and adaptability in various road layouts.
Innovation Solution
A reconfigurable reflective marker system featuring a pair of interlocking reflectors that can be positioned in orthogonal or parallel orientations on a support post, allowing for adjustable reflector configurations to enhance visibility in different traffic scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reflectors are fixed in a single orientation on the support post, then the structure is simple and stable, but the adaptability to different traffic directions is limited
Solution Approach 1:
The reflector mounting system transitions from a fixed static configuration to a dynamic reconfigurable system. The reflectors can be rotated and repositioned along the support post to different orientations (orthogonal for intersections, parallel for straight roads) based on traffic patterns, making the marker adaptable to various road layouts while maintaining a relatively simple interlocking mounting mechanism.
Solution Approach 2:
The reflector assembly is divided into separable components that can be independently positioned. Each reflector can be individually rotated and locked at different heights and orientations on the support post, allowing flexible configuration without requiring complete disassembly of the entire marker system.
2Adaptability or versatility
If reflectors are positioned in orthogonal directions for intersection visibility, then visibility in multiple directions is improved, but the compactness and aesthetic appearance is reduced
Solution Approach 1:
The reflector positioning system allows dynamic adjustment between orthogonal configuration (for intersection visibility where each reflector faces a different road) and parallel configuration (for straight roads where both reflectors face the same direction). This dynamic reconfigurability enables the marker to achieve multi-directional visibility when needed while maintaining a compact, aesthetically pleasing appearance during normal operation.
3Adaptability or versatility
If reflectors are made reconfigurable to optimize for different traffic scenarios, then visibility and adaptability are improved, but the ease of operation and installation is reduced
Solution Approach 1:
The mounting mechanism provides dynamic reconfigurability through rotatable joints and adjustable positioning features that allow reflectors to be reoriented between orthogonal and parallel configurations. While more complex than fixed mounting, the system maintains ease of operation through intuitive mechanical interfaces that can be adjusted by hand during installation and maintenance without requiring specialized tools or complex procedures.

AI summary
A reflective marker including first and second reflectors, each having a first and second reflective outer surfaces spaced apart by a peripheral rim. The first reflector further including a central region including a first open portion extending through the first reflector peripheral rim and a raised rib defining a blind hole extending from the first open portion for receiving a support post. The second reflector further including a central region including a second open portion extending through the second reflector peripheral rim and a raised rib defining a through bore extending from the second open portion for receiving the support post. The first open portion of the first reflector central region is sized to receive the raised rib of the second reflector central region and the second open portion of the second reflector central region is sized to receive the raised rib of the first reflector central region.
