Ridge Fixing Connecting Element for Weather Protection Netting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weather protection systems for plant cultures face challenges in achieving stable net fixation with easy assembly, as they are prone to punctiform stresses and require complex arrangements that can be load-intensive at binding points.
Innovation Solution
The design incorporates a lower part with a support structure protruding like wings from the wire guide for planar support of the fabric, a C-shaped wire guide that can be elastically opened for secure mounting, and a form-fitting assembly with screw channels for reliable clamping, along with a molded rib structure for stability and a hanging strap for easy gathering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fabric is secured to the ridge wire by a ridge seam with net connectors, then the net can be fixed to the ridge wire, but the net is subject to high loads at binding points and the width of netting panels is reduced
Solution Approach 1:
The patent introduces a lower part with a wire guide and support structure as an intermediary component between the ridge wire and the fabric. This mediator distributes loads through the wire guide that encases the ridge wire, while the support structure with acute roof inclination angle provides a broad bearing surface for the fabric, eliminating concentration of stresses at binding points and preventing run-off of weft threads.
2Reliability
If a sleeve-shaped inner part encases the ridge wire and interacts with an outer part for clamping, then the net can be secured, but the construction becomes complex and assembly difficult
Solution Approach 1:
The connecting element is divided into two functional segments: a lower part containing the wire guide and support structure for securing the ridge wire, and an upper part with clamping surfaces for securing the fabric. This segmentation allows each part to be optimized for its specific function while simplifying the overall assembly process compared to a single complex component.
Solution Approach 2:
The wire guide is designed with elastic properties allowing it to be spread open for lateral insertion of the ridge wire, then automatically closes to encase and secure the wire without requiring additional fastening operations. This self-service mechanism simplifies assembly while ensuring reliable fixation.
3Reliability
If the wire guide is designed to encase the ridge wire securely, then reliable fixing is achieved, but assembly becomes more difficult
Solution Approach 1:
The wire guide is designed with elastic flexibility that allows it to dynamically change its configuration during assembly. It can be spread open to accommodate lateral insertion of the ridge wire, then automatically returns to its closed encasing position to secure the wire. This dynamic behavior enables simple assembly while maintaining reliable fixation.

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 solution minimizes stress at the ridge connection point, ensures secure and easy assembly, and maintains the shape of the netting or foil web, providing stable fixation and easy operation for weather protection.
Implementation Method 1
the wire guide, which is C-shaped in cross section, can be spread open elastically for the lateral insertion of the ridge wire

AI summary
The connecting element (24) has a lower part having a wire guide axially penetrated by a ridge wire (18). The lower part is attached on a segment of a ridge wire. The lower part has a supporting structure for a flat support of the flat structure, where the supporting structure protrudes on both sides of the wire guide in a wing-like manner. An independent claim is also included for a weather protective roofing for plant cultures with a supporting structure.
