Privacy Screen Base with Friction Coating for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accident shielding solutions are not adequately stable or quick to assemble, and their designs obstruct traffic flow or are not suitable for busy roads due to voluminous structures and lack of frictional stability.
Innovation Solution
A screen design featuring an elongated plate with friction-increasing coating on its underside and four upwardly projecting sleeves for vertical support posts, allowing for quick assembly and stability, with the option to be safely rolled over by vehicles and anchored to prevent shifting, enabling flexible use on roads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If voluminous box-shaped feet are used to provide stability, then the screen is stable, but the feet obstruct traffic flow and are not suitable for busy roads
Solution Approach 1:
The patent replaces voluminous box-shaped feet with thin, plate-like feet that have high bending strength. These thin feet do not obstruct traffic flow while maintaining stability through their structural design and friction-increasing coating on the road surface.
2Productivity
If multiple handling steps are required for assembly, then the screen can be completely dismantled and stored space-saving, but the assembly takes a lot of time
Solution Approach 1:
The patent combines multiple components into integrated units. The frame-shaped support elements are pre-assembled with vertical support posts and horizontal connecting bars, and the feet are designed to be directly attached to the support posts, reducing the number of separate handling steps required during assembly.
3Stability of the object's composition
If the base has high friction with the ground to prevent shifting, then the screen is stable, but the base cannot be safely rolled over by vehicles
Solution Approach 1:
The patent applies friction-increasing coating only to specific contact areas of the feet that interact with the road surface, while the overall foot structure remains thin and vehicle-safe. This localized friction enhancement provides anti-shifting stability without creating obstacles that could damage vehicles.
4Ease of manufacture
If vertical support posts are inserted into holding feet with slot-shaped recesses, then the fabric web can be hung, but large gaps exist between individual stands
Solution Approach 1:
The patent uses frame-shaped support elements with multiple vertical support posts connected by horizontal connecting bars, creating segmented structures that can be closely spaced. This segmentation allows the screen to be assembled from modular units while minimizing gaps between stands for better continuity.
