Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional road barrier systems, especially temporary barriers, are prone to safety risks due to detachment during vehicle impacts and high maintenance costs, leading to insufficient safety and frequent repairs.
Innovation Solution
A shock absorber system featuring an inner pipe bumper with a ground shaft support base and a connecting member that absorbs impact through elastic rail tension, allowing for easy installation and replacement of guardrails in high-risk areas, reducing construction costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional temporary barriers are installed to substitute guard rails, then construction cost is reduced and installation is simplified, but safety reliability deteriorates due to detachment during vehicle impact
Solution Approach 1:
The barrier system is divided into modular components: barrier walls, support pillars, and shock absorbers that can be independently installed and replaced. This segmentation allows for simplified installation while maintaining overall system reliability through proper energy absorption mechanisms.
Solution Approach 2:
Shock absorbers are pre-installed at strategic locations where vehicle impacts are most likely to occur. This beforehand cushioning ensures that when impacts happen, the energy is absorbed in advance-designed locations, preventing detachment and maintaining safety reliability.
2Reliability
If guard rails and support pillars are frequently repaired due to aging and damage, then safety is maintained, but construction cost increases and maintenance time is extended
Solution Approach 1:
The shock absorber system is designed with replaceable components that can be easily discarded after absorbing impact energy and recovered/replaced without disturbing the entire barrier structure. This significantly reduces maintenance time and improves productivity while maintaining safety.
Solution Approach 2:
The shock absorption function is extracted as a separate, independent component from the main guard rail structure. This allows the shock absorbers to be individually replaced without repairing the entire barrier system, improving maintenance efficiency.
3Reliability
If shock absorbers are installed in all danger zones, then safety is improved, but construction cost increases
Solution Approach 1:
Shock absorbers are strategically installed only at specific high-risk locations where vehicle impacts are most likely to occur, such as steep slopes, concrete barriers, and electric poles. This localized approach maintains safety in critical areas while reducing overall construction cost.
Solution Approach 2:
Instead of installing shock absorbers uniformly throughout the entire barrier system, the invention applies partial action by installing them only where most needed, optimizing the balance between safety improvement and construction cost.

Function Achieved in This Case
The system effectively buffers collision impacts, enhancing safety and reducing maintenance costs by enabling selective installation in danger zones and easy replacement of aged guardrails, applicable to various barrier locations.
Implementation Method 1
the impact of the barrier wall is absorbed by the tension of the elastic rail when the buffer pad is up-shifted due to the external force of the collision

AI summary
Disclosed is a shock absorber for buffering the barrier wall of a road. According to the present invention, a horizontal inner pipe bumper is inserted into a pedestal attached to a boundary of a barrier wall and joined to the support pillar. The buffer rail transversely connected to the protruding portion of the buffer pad on the front surface of the pedestal constitutes the buffer portion of the collision portion barrier wall, and when the buffer pad adhered to the inner pipe bumper is displaced upright, tension of the elastic rail connecting the buffer pad and the elastic rail block is generated, and the guard rail of the pillar is coupled to the barrier bridging body by a connecting member.
