Detachable Reflector for Embedded Road Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current embedded-type reflective road markers lose reflectivity over time and require cumbersome replacement processes, and existing systems lack the ability to easily change the color of reflected light for different road features without removing and replacing the markers.
Innovation Solution
A detachable reflector connection system using a reflector retention cartridge with slidable members and release means, such as clips or pins, allows for easy removal and replacement of the reflector without disturbing the base, enabling color variation by adjusting the reflector's orientation and attachment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reflector is permanently fixed to the base using adhesive, then the marker is stable and secure, but the reflector cannot be easily removed or replaced when it loses reflectivity
Solution Approach 1:
The connector is divided into two separate members: a first member fixed to the base and a second member fixed to the reflector. These members can slide relative to each other to enable easy separation and reattachment of the reflector while maintaining secure fixation during normal use.
Solution Approach 2:
The connector transitions from a static permanent adhesive bond to a dynamic mechanical connection that allows controlled movement. The slidable members enable the connector to shift between locked and unlocked states, facilitating reflector replacement while maintaining operational stability.
2Reliability
If the reflector is embedded deep in the road surface, then it is less susceptible to dislodgement, but it requires more road material removal and more complex installation
Solution Approach 1:
The marker is segmented into a base structure that remains embedded in the road and a separate reflector assembly that can be independently installed and removed. This allows the base to provide anchoring stability while the reflector can be easily replaced without disturbing the embedded portion.
Solution Approach 2:
The reflector is extracted from the permanent fixed connection and made separable through the connector mechanism. This allows the reflector to be removed and replaced independently while the base remains embedded in the road surface, simplifying both installation and maintenance.
3Adaptability or versatility
If different colored reflectors are used to indicate different road features, then the road markings can convey different information, but changing the color requires removing and replacing the entire marker
Solution Approach 1:
The reflector is separated from the base through the detachable connector, allowing the reflector (which determines color) to be independently replaced. This enables color changes by swapping only the reflector component rather than the entire marker assembly.
Solution Approach 2:
The connector design provides universal compatibility, allowing different reflectors with various colors and reflective properties to be attached to the same base. This enables the road marker to serve multiple functions and convey different information by simply changing the reflector.
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
Facilitates efficient and non-invasive maintenance of road markers by allowing for quick replacement of reflectors without digging up the road, reducing time and effort, and enabling easy reconfiguration of reflective colors by changing the reflector assembly.
Implementation Method 1
a reflector for reflecting light cast onto the marker
Implementation Method 2
The clip may be resiliently biased, in use, toward the base, for example to provide an interference or snap fit therewith
