Rising Traffic Bollard Sliding Profiles and Adjustable Skids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rising traffic bollards face issues such as component wear, misalignment, and aesthetic damage due to friction and external stresses, leading to costly maintenance and reduced operational reliability.
Innovation Solution
The bollard features sliding profiles and skids with adjustable support bodies to minimize friction and wear, allowing for easy replacement of worn components and maintaining alignment, using materials with enhanced sliding properties like PVC and acetal resin, and a solid steel or aluminum side wall for resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bollard element slides in the supporting structure using conventional actuators, then the bollard can move between extracted and retracted positions, but friction causes wear and damage to moving components over time
Solution Approach 1:
The patent introduces sliding profiles with low-friction surfaces as intermediary elements between the bollard element and supporting structure. These profiles act as mediators that reduce direct metal-to-metal contact, thereby minimizing friction and wear while enabling smooth movement of the bollard element between extracted and retracted positions.
2Strength
If the bollard element is knocked by a motor vehicle, then the bollard element may be put out of axis, but this increases friction and wear between mobile components
Solution Approach 1:
The patent employs adjustable support bodies that can dynamically adapt their position and orientation in response to external forces such as knocks. This dynamic adjustment capability allows the system to maintain proper alignment of the bollard element even after impact, preventing increased friction and wear that would result from misalignment.
3Ease of operation
If the bollard element slides inside the supporting structure, then the bollard can function, but scratches and marks appear on the side surface of the bollard element
Solution Approach 1:
The sliding profiles serve as protective intermediary surfaces between the bollard element and supporting structure. These profiles are designed with specialized low-friction coatings that enable smooth sliding while protecting the side surface of the bollard element from scratches and marks, thereby maintaining its aesthetic appearance.
4Adaptability or versatility
If motor vehicles are parked at a bollard in retracted position, then the bollard allows passage, but the actuator is subjected to stress and misalignments occur
Solution Approach 1:
The adjustable support bodies can dynamically reposition themselves to accommodate external objects such as parked vehicles. When a vehicle is detected in the retracted position, the support bodies adjust to bear the load and prevent stress transmission to the actuator, thereby maintaining reliability while allowing passage.
