Solution Overview
Problem
Existing barriers for accident sites and outdoor events lack stability and resistance to adverse weather conditions, while also being cumbersome and inefficient in space utilization.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional solid barriers are used for accident sites, then stability is improved, but wind resistance deteriorates and space utilization worsens
Solution Approach 1:
The barrier incorporates a porous wall structure with numerous holes distributed throughout. This porous design allows wind to pass through the barrier rather than creating excessive pressure buildup, significantly reducing wind resistance while maintaining structural stability through the rigid framework and base connection.
Solution Approach 2:
The barrier combines rigid structural elements (metal or plastic frame, base) with permeable wall sections. This composite construction maintains stability through the rigid components while the permeable sections reduce wind load, resolving the contradiction between stability and wind resistance.
2Stability of the object's composition
If traditional solid barriers are used for accident sites, then stability is improved, but space utilization deteriorates
Solution Approach 1:
The porous wall structure with holes allows the barrier to enclose a larger volume while occupying less ground area. The permeable design enables space-efficient configuration where the barrier can be positioned closer to traffic flow without creating excessive wind pockets, improving overall space utilization.
3Object-affected harmful factors
If air-filled walls with holes are used, then wind resistance is reduced, but structural rigidity deteriorates
Solution Approach 1:
The barrier uses a composite construction where rigid frame elements (metal or plastic) provide structural strength and rigidity, while the permeable wall sections reduce wind resistance. The rigid framework maintains structural integrity even with the porous wall design.
Solution Approach 2:
The air-filled chambers within the wall structure provide internal pressure to maintain rigidity and shape, compensating for the reduced structural support from the porous design. The pressurized air acts as a structural element, maintaining wall stiffness while allowing the permeable configuration.
4Stability of the object's composition
If hinged connection with angular inclination is used, then stability under weather conditions is improved, but device complexity increases
Solution Approach 1:
The hinged connection with angular inclination allows the barrier to dynamically adjust to weather conditions. The hinge enables controlled movement and rotation, allowing the barrier to adapt to wind loads and environmental forces while maintaining stability, rather than relying on fixed rigid connections.
