Storm Spring Torque Mechanism for Roof Tile Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storm clips for connecting roof tiles to battens require different wire lengths for varying tile heights and create a rigid connection, which can lead to damage during strong winds and are difficult to handle and install.
Innovation Solution
A storm spring with a holding device, clamping device, and leg spring that introduces torque to resiliently press the roof tile against the batten, allowing for elastic movement and universal use across different tile heights, featuring a design with multiple turns and a configuration that distributes spring force effectively to maintain constant pressure over a wide angular range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If wire elements are used to connect roof tiles to battens, then the roof tile can be fixed to the batten, but the connection becomes rigid and strong winds can directly damage the roof structure
Solution Approach 1:
The patent replaces rigid wire elements with a flexible spring mechanism that can elastically deform under wind loads. The spring allows the roof tile to move relative to the batten, absorbing wind energy and preventing rigid connection failures during storms.
2Reliability
If wire elements of different lengths are used for roof tiles of different heights, then secure fixing is achieved, but the device complexity and handling difficulty increase
Solution Approach 1:
The patent designs a universal spring mechanism that can accommodate roof tiles of various heights through elastic deformation. The spring's flexibility allows it to maintain secure fixation across different tile configurations without requiring multiple specialized components, simplifying both the device and installation process.
3Force
If wire elements are used for clamping, then the roof tile can be secured, but the wire elements create a rigid connection that transmits wind forces directly to the structure
Solution Approach 1:
The patent transitions from a static rigid wire connection to a dynamic spring-based connection that can adapt its stiffness and deformation characteristics. The spring maintains sufficient clamping force for secure fixation while allowing controlled movement to absorb wind energy, preventing force transmission that could damage the roof structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The storm spring provides a flexible connection that absorbs wind energy, prevents roof tile destruction, allows for non-destructive lifting for maintenance, and maintains secure attachment across varying tile heights and wind conditions, while being easy to handle and install.
Implementation Method 1
a torque can be introduced into the holding device by means of the leg spring, so that the roof tile can be resiliently pressed against the roof batten via the holding device
Implementation Method 2
the connection between the roof tile and the batten can be made elastic. By means of a corresponding design of the leg spring, in particular a design with more than one turn, the storm spring can be operated in an elastic range
Implementation Method 3
The corresponding energy of the storm gust is at least partially initially absorbed by the torsion springs and then used to pull the roof tile back into its position
