Roller Shutter Assembly Using Belt Straps as Damping Traction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing roller shutter curtains on winding shafts require heavy equipment and complex assembly processes, increasing labor and resource demands.
Innovation Solution
A method involving the use of at least two belt straps as assembly traction means to lift and wind the roller shutter curtain onto the winding shaft, with the straps remaining between the curtain and the shaft for easy operation and damping, eliminating the need for heavy lifting devices and complex assembly structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the roller shutter curtain is lifted as a compact unit onto the brackets using a winding shaft, then the curtain can be securely attached to the supporting structure, but heavy mobile equipment such as cranes or complex auxiliary structures are required
Solution Approach 1:
The patent introduces an assembly device as an intermediary tool between the workers and the roller shutter curtain. This assembly device includes a support structure with a support beam that can be temporarily attached to the supporting structure, providing a lightweight platform for workers to access the curtain without requiring heavy cranes or complex auxiliary structures.
Solution Approach 2:
The assembly device is designed to be self-supporting through its support structure that attaches to the existing supporting structure. The device includes its own working platform and access means, eliminating the need for external heavy equipment while providing all necessary functions for curtain assembly.
2Ease of operation
If assembly devices are attached to support brackets to pull the curtain into position, then the curtain can be positioned above the opening, but increased assembly work is required to attach the assembly parts and lowering device
Solution Approach 1:
The patent combines multiple functions into the assembly device: the support structure provides both the mounting platform and the pulling mechanism attachment point. The lowering device is integrated into the assembly device rather than being a separate component, reducing the number of attachment operations required.
Solution Approach 2:
The assembly device serves multiple purposes: it provides a support platform for workers, serves as the attachment point for the pulling mechanism, and includes the lowering device for final positioning. This multi-functionality reduces the overall assembly work compared to using separate dedicated components for each function.
3Ease of manufacture
If the winding shaft is installed without the roller shutter curtain, then the shaft can be positioned at the end position and rotatably fastened, but the curtain must then be pulled up using assembly traction means
Solution Approach 1:
The patent divides the installation process into separate stages: first installing the winding shaft independently at its final position, then separately pulling up the curtain using assembly traction means. This segmentation allows the shaft to be precisely positioned and secured without the complexity of handling the entire curtain-shaft assembly together.
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
This method simplifies the installation process, reduces assembly effort, and allows the assembly traction means to serve as a damping layer, enhancing the smooth operation of the roller shutter.
Implementation Method 1
at least two belt straps (42, 44) are fastened as assembly traction means... Pulling up an upper end area (12, 10) of the roller door curtain (10) onto the winding shaft (30) by means of the assembly traction means by winding the assembly traction means onto the winding shaft
Implementation Method 2
at least two belt straps (42, 44) are fastened as assembly traction means... Pulling up an upper end area (12, 10) of the roller door curtain (10) onto the winding shaft (30) by means of the assembly traction means
Implementation Method 3
the at least two belt straps (42, 44) wound around the winding shaft (30) can serve as a damping intermediate layer between the roller shutter curtain (10) and the winding shaft (30)... enhancing the smooth operation of the roller shutter
Implementation Method 4
the at least two belt straps (42, 44) wound around the winding shaft (30) can serve as a damping intermediate layer between the roller shutter curtain (10) and the winding shaft (30)... enhancing the smooth operation of the roller shutter

AI summary
The method involves assembling a winding shaft (30) without a rolling gate hanging (10) at the assembly position. An upper final range of the rolling gate hanging is lifted on the winding shaft by assembly drawing device and by rolling assembly drawing device on the winding shaft. The rolling gate hanging is rolled on the winding shaft. The assembly drawing device remains between the roling gate hanging and the winding shaft. An independent claim is also included for a rolling gate, which has rolling assembly drawing device.
