Vertical Axis Barrier for Fluid Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barriers for preventing liquid or granule ingress in underground car parks and similar applications often require significant headroom, limit passage height, or necessitate laborious installation, and struggle to overcome small obstacles.
Innovation Solution
A barrier design featuring a barrier body that rotates about a vertical axis, utilizing a swivel joint connected to a rotary barrier mount with adjustable alignment, and equipped with four-bar linkages for movement, allowing the barrier to be raised and lowered without reducing clear height or width, and incorporating seals and a spring-loaded mechanism for automatic closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the barrier body is pivoted upwards to enable opening and closing movement, then the barrier can be opened and closed, but a very large headroom is required which is not available in many applications
Solution Approach 1:
The barrier body is rotated about a vertical axis instead of a horizontal axis, changing the dimension of rotation from horizontal to vertical. This allows the barrier to open and close in a horizontal plane rather than requiring vertical headroom for pivoting movement.
Solution Approach 2:
The barrier system uses a dynamic linkage mechanism with four-bar linkages that allow the barrier body to move between horizontal and vertical positions. The linkage enables automatic positioning and sealing actions without requiring continuous manual operation or excessive headroom.
2Ease of operation
If the barrier can be pulled upwards to enable opening and closing, then the barrier can be operated, but the remaining passage height is limited
Solution Approach 1:
By changing the rotation axis from horizontal to vertical, the barrier operates in a different spatial dimension. The barrier body rotates about a vertical axis, allowing horizontal movement that does not interfere with vertical passage height.
3Reliability
If the barrier is lowered into the ground to enable sealing, then sealing is achieved, but considerable effort is required during installation and ceiling thickness limits usage
Solution Approach 1:
The barrier sealing mechanism operates in a horizontal plane rather than requiring vertical burial into the ground. The barrier body can be positioned horizontally against a vertical surface, eliminating the need for extensive vertical installation effort.
Solution Approach 2:
The barrier system includes automatic sealing mechanisms that engage when the barrier body is positioned correctly. The sealing elements automatically contact the sealing surfaces without requiring manual adjustment or extensive installation preparation.
4Reliability
If the barrier uses traditional sealing mechanisms, then sealing is achieved, but small obstacles on the roadway cannot be overcome
Solution Approach 1:
The barrier body is designed with dynamic positioning capability through four-bar linkages that allow it to move between horizontal and vertical positions. This dynamic adjustment enables the barrier to overcome small obstacles on the roadway during its operation.
Solution Approach 2:
By rotating about a vertical axis, the barrier can achieve horizontal movement that allows it to bridge small obstacles. The vertical rotation axis enables the barrier body to position itself over obstacles in the horizontal plane.

AI summary
The barrier has a barrier body (2) rotating in a barrier support (4) in a horizontal opening position and comprising an end (5). The end of the body is rotatably arranged at a swivel-joint (10) by four-bar coupling mechanism (11). A swivel movement of the barrier body between an upper position and a lower position contains a moving component in a direction of an axis of the swivel joint. The body is locked in the horizontal opening position by a holding device.
