Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for winding and unwinding flat material webs onto and off winding shafts lack a simple, detachable, and reliable connection, which is crucial for awnings used outdoors and often in confined spaces, where weather exposure and difficult installations necessitate easy assembly and replacement.
Innovation Solution
A winding system featuring a winding shaft with a groove and a profile-shaped connecting device that includes clamping elements, a support element, and a tab-shaped handle, allowing for a detachable and reliable connection by elastic deformation for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable connection is used between the flat material web and the winding shaft, then the ease of installation and maintenance is improved, but the reliability of the connection may worsen
Solution Approach 1:
The connection system is divided into separate components: a profile-shaped connecting device with clamping elements that can be detached from the winding shaft groove. This segmentation enables easy installation and maintenance while maintaining reliable connection through the clamping mechanism that engages with the groove structure.
Solution Approach 2:
The profile-shaped connecting device acts as an intermediary element between the flat material web and the winding shaft. It features clamping elements that engage with the groove to provide reliable connection, while its modular design allows for easy attachment and detachment, resolving the contradiction between connection reliability and ease of installation.
2Manufacturing precision
If the flat material web is tightly connected to the winding shaft to prevent bulges, then the manufacturing precision is improved, but the ease of detachment worsens
Solution Approach 1:
The clamping elements are designed to be elastically deformable, allowing dynamic adjustment between a clamped state that prevents bulges and maintains surface flatness, and a released state that enables easy detachment. The elastic deformation capability allows the connection to be tight during operation but easily release when needed.
Solution Approach 2:
The clamping force parameter can be changed by deforming the profile-shaped connecting device. In the clamped state, high clamping force prevents bulges and ensures manufacturing precision. For detachment, the clamping force is reduced through elastic deformation, allowing easy release without compromising the tight connection during normal operation.
3Reliability
If the groove extends deep under the outer surface to provide secure clamping, then the connection reliability is improved, but the device complexity worsens
Solution Approach 1:
The groove structure is segmented into an outer surface portion and an underlying recess portion. This segmentation allows the groove to extend securely under the outer surface for reliable clamping while maintaining a relatively simple overall structure that is easy to manufacture and install.
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
Enables a simple, detachable, and reliable connection of the flat material web to the winding shaft, preventing bulges and color changes, facilitating easy installation and maintenance, and ensuring uniform force profiles during winding and unwinding.
Implementation Method 1
The profile-shaped connecting device (5) is elastically bendable, particularly in a direction transverse to the longitudinal direction of the profile-shaped connecting device (5). The tab-shaped handle (11) is connected to the support element (8) in such a way that by gripping and pulling the tab-shaped handle (11), the profile-shaped connecting device (5) can be bent in the clamped state in such a way that the distance A decreases

AI summary
The invention relates to a winding system (1) for winding and unwinding a flat material web (2) onto and from a winding shaft (3). The winding system (1) has a winding shaft (3) with a groove (4) in its outer surface and a profiled connecting device (5). The profiled connecting device (5) has a connecting tab (9) for connecting a flat material web edge (10) to the profiled connecting device (5) and a tab-shaped handle (11). The groove (4) has a recess (6) that extends axially and circumferentially along the winding shaft (3) and under the outer surface of the winding shaft (3). The profiled connecting device (5) can be inserted into the groove (4) and can be detachably clamped in the recess (6) by means of two clamping elements (7a, 7b).By manipulating the tab-shaped handle (11), the profile-shaped connecting device (5) can be elastically bent so that it can be inserted into the groove (4) and clamped in it or removed from the groove (4).
