Pleated Mosquito Net Cable Tensioning for Smooth Side Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mosquito nets face issues with improper wire tensioning leading to poor fit and instability, and mechanisms like chains and straps are prone to breakage or rust, causing rigidity and noise during operation.
Innovation Solution
A screwdriver-adjustable connection piece at the lower end of the fixed post for vertical alignment, a cable tension adjustment element with an Allen key/screwdriver, and a rounded caterpillar-type chain for smooth sliding, replacing traditional chains/straps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional chains or straps are used for lateral movement, then the mosquito net can be opened and closed, but the chains may come out of profiles and break or the strap may break and rust due to rigidity and continued use
Solution Approach 1:
The patent removes the problematic chain and strap components from the system. Instead of using traditional chains that can come out of profiles or straps that can break and rust, the invention extracts these elements entirely and replaces them with a cable-based pulling mechanism that eliminates the reliability issues while maintaining operational functionality.
Solution Approach 2:
The patent introduces a cable as an intermediary element between the control mechanism and the mosquito net fabric. This cable, combined with a reel mechanism, serves as a more reliable mediator than chains or straps, providing smooth operation without the risk of coming out of profiles or breaking due to rust.
2Reliability
If wires are tensioned to hold and stabilize the pleated fabric, then the mosquito net functions correctly, but improper tensioning leads to poor fit and instability requiring installer knowledge and time
Solution Approach 1:
The patent implements a self-adjusting tensioning mechanism where the cable and reel system automatically maintains proper tension on the pleated fabric. The reel mechanism allows the system to self-regulate wire tension without requiring installer knowledge or manual adjustment, eliminating the complexity while ensuring stable fabric positioning.
Solution Approach 2:
The patent changes the tensioning parameter from fixed wire tension requiring manual adjustment to a dynamic cable tension system controlled by a reel mechanism. This allows the tension parameter to be easily adjusted and maintained at optimal levels without complex installation procedures or specialized installer knowledge.
3Ease of operation
If ant-type chains are used for lateral sliding, then the mosquito net can be moved sideways, but the product operates more rigidly and noisily
Solution Approach 1:
The patent removes the ant-type chain component that causes noise and rigidity during lateral sliding. By extracting this problematic element and replacing it with a cable-reel mechanism, the system maintains lateral sliding capability while eliminating the harmful noise and excessive rigidity associated with traditional chain designs.

AI summary
The purpose of the present invention, which relates to a mosquito net, is to improve and streamline the installation and subsequent use of side-opening pleated mosquito nets, thereby increasing the performance and durability of the product. The mosquito net comprises: a fabric that moves between a closed position and an open position, and vice versa; and a pull element for moving the fabric, comprising a cable part that runs through a frame by means of pulleys, wherein the frame comprises a fixed profile and a movable profile, the movable profile pivoting relative to the fixed profile.
