Rotatable Wing Safety Line Support for Roof Ridge Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety line supporting devices are difficult to mount on roof ridges due to their flat plate design, which does not adapt well to varying roof slopes, and their dimensions pose challenges in transportation and storage.
Innovation Solution
A supporting device with a plate-shaped main body and rotatable wings, featuring through slits and tabs for mechanical coupling, allowing for precise longitudinal adjustment and adaptation to different roof angles, and a method for installing it on roof ridges using mounting bars or clamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat plate design is used for the supporting device, then the structure is simple and easy to manufacture, but it cannot adapt to varying roof slopes and is difficult to mount on roof ridges
Solution Approach 1:
The supporting device is divided into a main body and two wings that can be independently positioned and adjusted. The wings are separated from the main body and connected through slits, allowing each component to be optimized for its specific function while maintaining overall simplicity in manufacturing.
Solution Approach 2:
The wings are made rotatable relative to the main body through the slit connection, transforming the static flat plate into a dynamic structure that can adapt to different roof slopes and orientations. This rotational capability allows the device to accommodate varying roof angles without requiring multiple custom-designed components.
2Strength
If the plate dimensions are increased to provide stable support, then the supporting strength is improved, but the transportation and storage space requirements increase
Solution Approach 1:
By dividing the structure into a main body and two wings, the device can be collapsed into a compact form for transportation and storage, reducing the volume occupied. When deployed, the wings extend to provide the necessary supporting strength and stability.
Solution Approach 2:
The wings can be folded against or alongside the main body when not in use, creating a nested configuration that minimizes the overall dimensions. This allows the device to be stored in a compact state while maintaining full functionality when deployed.
3Manufacturing precision
If through slits and tabs are used for mechanical coupling, then the wings can be precisely adjusted longitudinally, but the device complexity increases
Solution Approach 1:
The connection system is segmented into discrete tabs and corresponding slits, allowing for precise positioning through the selection of specific tab-slit pairs. This segmented approach provides adjustable precision without requiring complex continuous adjustment mechanisms.
Solution Approach 2:
The tabs act as intermediaries between the wings and the main body, providing a simple mechanical coupling system. The tabs insert into the slits to create a straightforward connection that enables precise adjustment while maintaining low device complexity.
