Delineator Mounting System With Square Cavity Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic delineators face challenges in being inexpensive, easy to install, and durable enough to withstand vehicle impacts, while also requiring quick replacement and resistance to damage from pedestrian and vehicular traffic.
Innovation Solution
A delineator mounting system featuring a coupler with a cylindrical tubular lower end that mates with a curb-like mount having a square cross-section, allowing for secure and flexible installation using fasteners or adhesive, and incorporating a transition portion with abutment projections for impact resistance, along with recessed pads for reflective markers and a ribbed design for reduced surface contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional delineator mounting system is used, then the installation process is simple and quick, but the delineator cannot withstand multiple vehicle impacts without damage or removal from the ground
Solution Approach 1:
The mounting system is divided into separate components: a ground-mounted base structure and a delineator post that can be independently installed and replaced. This segmentation allows the post to be replaced without damaging the permanent base, enabling quick replacement while maintaining overall system strength.
Solution Approach 2:
The delineator post is inserted into and nested within the ground-mounted base structure. This nesting arrangement provides a secure fit that withstands vehicle impacts while keeping the overall mounting system relatively simple and compact.
2Reliability
If the delineator is designed for durability and impact resistance, then it can withstand vehicle impacts, but the installation and replacement process becomes more time-consuming and complex
Solution Approach 1:
By segmenting the system into a permanent base and a removable post, the design achieves durability through the robust base while enabling quick replacement of the post without requiring complex demolition or reconstruction processes.
Solution Approach 2:
The ground-mounted base is pre-installed and secured in the ground before the delineator post is attached. This preliminary action creates a ready-made mounting structure that allows for rapid post installation or replacement without requiring time-consuming ground preparation each time.
3Strength
If the delineator uses a secure mounting system to withstand impacts, then it remains firmly connected to the ground, but it becomes more difficult to quickly replace when damaged
Solution Approach 1:
The segmentation of the mounting system into a permanent base and a removable post enables strong connection during normal operation while allowing easy separation for replacement. The base remains firmly anchored to the ground, but the post can be quickly detached and replaced without affecting the base's secure connection.
