Magnetic Support for Roller Mosquito Net Guide Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Roller mosquito nets tend to form bends when the guide elements are stretched, especially in large windows, allowing insects to enter and compromising their insect-proof function.
Innovation Solution
The integration of magnetic supports between the guide elements and the sectional elements prevents bending by using magnetic and metal portions that attract and adhere to each other, maintaining the guide elements' tension and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If guide elements are stretched to cover large windows, then the coverage area is improved, but bends form in the middle causing insects to enter
Solution Approach 1:
The guide element is divided into multiple articulated segments that can flex independently. This segmentation allows the guide element to span large areas while maintaining tension through the articulated structure, preventing bends that would compromise insect-proof functionality.
Solution Approach 2:
Magnetic support elements are strategically positioned at specific locations along the guide element to provide localized support where bends are most likely to occur. This local reinforcement maintains the overall tension and flatness of the guide element across large window areas.
2Reliability
If magnetic support elements are added to prevent bends, then the guide element tension is maintained, but the device complexity increases
Solution Approach 1:
Traditional mechanical support structures (such as rods, clips, or tensioning mechanisms) are replaced with magnetic support elements. These magnetic elements provide the necessary holding force through magnetic attraction alone, eliminating complex mechanical assemblies while maintaining guide element tension and preventing bends.
3Device complexity
If traditional mechanical supports are used, then the structure is simple, but the operation speed is slow and manual effort is required
Solution Approach 1:
Manual mechanical support and adjustment mechanisms are replaced with magnetic support elements that automatically engage and maintain tension. This substitution eliminates the need for manual adjustment during operation, significantly increasing operation speed while keeping the overall structure relatively simple.
Solution Approach 2:
The magnetic support elements automatically engage with the guide element through magnetic attraction, providing self-adjusting support without requiring manual intervention. This self-service capability accelerates operation speed while maintaining structural simplicity.

AI summary
A roller mosquito net (1), comprising a fixed sectional element (10), a mobile sectional element (11), which is arranged parallel to said fixed sectional element (10), and a screen (13), which, at one end, is wound on a roller (12) that has a first and second end and is arranged within said mobile sectional element (11), and, at its opposite end, is fixed to said fixed sectional element (10). The roller mosquito net (1) comprises, furthermore, guide elements (14,24) of the mobile sectional element (11), which consist of a plurality of bodies (30,30a), which are hinged to each other and slide inside a guide sectional element (9), which is supported by the frame of the mosquito net (1). The mosquito net (1) comprising, furthermore, support means (41,42), adapted to support the upper guide element (14), in order to avoid the formation of bends when the mosquito net (1) is stretched. The support means comprise a metal portion and a magnetic portion, one associated to the upper guide and one associated to the sectional element for mutually interacting.
