Autonomous Anti-Mosquito Net With Wire Rope Pulley Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-mosquito net systems face issues with rope damage, incorrect dimension measurements leading to unusable systems, and limited width coverage due to restrictive guide components, requiring complex and costly adjustments or replacements.
Innovation Solution
An autonomous two-sided opening system using a straight permanent guide with ropes starting from one vertical case, running parallel to the net, and guided through pulleys to an upper and lower fixed horizontal guide, allowing for adjustable tension and easy installation in various heights, enabling wider openings without the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ropes are used to run through the net and across the bottom guide, then the net can be folded and unfolded, but the ropes are often cut due to usage and passing of users, requiring arduous replacement
Solution Approach 1:
The invention extracts the problematic rope component from the system and replaces it with an alternative mechanism. The bottom guide is redesigned to allow the net to be folded and unfolded without requiring ropes that run across it, thereby eliminating the rope cutting issue while maintaining the net's operational functionality.
Solution Approach 2:
The invention introduces an intermediary mechanism (the redesigned bottom guide structure) that mediates between the need for net folding/unfolding and the requirement to eliminate rope usage. This intermediary allows the net to change shape without relying on the problematic rope system.
2Ease of manufacture
If the system is made as a single technical element with fixed dimensions, then it can be fastened at the particular opening, but if dimensions are measured incorrectly, the entire system becomes useless and cannot be fixed
Solution Approach 1:
The invention segments the anti-mosquito system into separate, interchangeable components (vertical guides, horizontal guides, retention cases, sliding cases) that can be independently adjusted and replaced. This allows correction of dimension errors by replacing individual components rather than the entire system.
Solution Approach 2:
The invention introduces adjustable and replaceable components that allow the system dimensions to be dynamically modified after installation. The vertical side guides and horizontal guides can be replaced with different dimensions to correct measurement errors.
3Strength
If rope end components are used to fasten ropes to the system, then the ropes can be secured, but the movement of the ropes is terminated at the guide components, preventing complete opening of leaves when frame width exceeds height
Solution Approach 1:
The invention extracts the rope end components that limit rope movement and replaces them with a different fastening mechanism. The new design allows ropes to remain secured while extending their range of motion to accommodate frame widths greater than height.
Solution Approach 2:
The invention changes the dimensional constraints of the rope system by removing the limiting components. This allows the ropes to operate in an extended dimensional space, enabling the net to open completely even when the frame width exceeds its height.
4Stability of the object's composition
If the two horizontal guides are permanently attached to the retention and sliding cases, then the system structure is stable, but the guides cannot be detached without dismantling the whole system
Solution Approach 1:
The invention segments the connection between the horizontal guides and the cases, introducing detachable coupling mechanisms. This allows the guides to be securely attached during operation for stability, but easily detached for replacement or repair without dismantling the entire system.
Solution Approach 2:
The invention introduces dynamic attachment characteristics to the guide-system connection. The guides can be firmly fixed during normal operation to maintain stability, but can be quickly detached when maintenance or replacement is needed.

AI summary
The system has a pleated net run by ropes that begin from the same side of the retention case, cross the net and continue upwards to all upper fixed horizontal guide, and are fastened at the upper part of the system. This invention uses wire rope which has one edge fastened at the upper truck, passes horizontally above the net, then parses through the pulley at the upper part of the sliding case, follows a vertical course towards the second pulley at the lower part of the sliding guide, crosses the lower fixed horizontal guide and is fastened on the lower part of the vertical fixed side guide. In case of a system with two or more leaves, this invention uses a ropes' central end component, tension adjusters and a ropes' run component.
