Double-Layer Drying Rack Cover With Spring Roll Wind Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry drying rack cover devices are prone to damage from wind, can leave laundry uncovered, and fail to protect external sides from rain and pollution, with high production costs and limited coverage.
Innovation Solution
A double-layered roll cover system with rigid sticks to maintain cloth tension and positioning, featuring a spring roll mechanism that unwraps to cover both upper and external sides of the drying rack, using magnetic sticks for secure attachment and adjustable tension to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cloth is fixed more firmly to the side bars of the drying rack, then the cloth stability is improved, but the cloth is more susceptible to wind damage and tearing
Solution Approach 1:
The drying rack is divided into multiple horizontal bars, and the cloth is secured to each bar individually using separate fastening elements. This segmentation allows the cloth to be distributed across multiple attachment points, reducing the stress concentration on any single point while maintaining overall stability.
Solution Approach 2:
The fastening system uses adjustable and removable fasteners that allow the cloth to be dynamically secured at different tension levels. This enables the user to adjust the cloth tension to balance stability with wind resistance, and to quickly remove the cloth during high wind conditions.
2Object-affected harmful factors
If the cloth is fixed loosely to the side bars of the drying rack, then the wind damage is reduced, but the cloth can wrap around itself or move, leaving the laundry uncovered
Solution Approach 1:
The cloth is pre-tensioned during installation to achieve optimal coverage before wind loads are applied. The fastening system is designed to maintain this pre-tension, ensuring the cloth remains taut and properly positioned during normal use while still allowing for wind flexibility.
Solution Approach 2:
The fastening system allows for adjustment of the cloth tension parameter. Users can optimize the tension level based on weather conditions - tighter for stability during calm periods, looser for wind protection during stormy weather - thus dynamically changing the parameter to balance both requirements.
3Device complexity
If a single layer of cloth is used to cover the drying rack, then the device complexity is reduced, but the protection against rain and pollution is insufficient
Solution Approach 1:
The invention transitions from a single-layer horizontal cover to a two-layer configuration where the first cloth layer covers the top surface and the second cloth layer covers the side/external surfaces. This dimensional expansion provides comprehensive multi-directional protection against rain and pollution while maintaining relatively simple implementation.
4Ease of manufacture
If a single layer of cloth is used to cover the drying rack, then the production cost is reduced, but the comprehensive protection coverage is limited
Solution Approach 1:
The protection system is segmented into two functional layers: a first cloth for top coverage and a second cloth for side coverage. Each layer can be manufactured and installed independently, allowing for cost-effective production while achieving comprehensive coverage of all exposed surfaces.
Solution Approach 2:
Both cloth layers use the same material and fastening mechanism, making the system universal and easy to manufacture. The dual-layer design provides multi-functional protection (top + side coverage) without requiring different materials or complex assembly procedures, thus maintaining cost-effectiveness.
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
Provides comprehensive protection against wind, rain, and pollution, ensuring the laundry is fully covered without risking damage or exposure, while being cost-effective and aesthetically pleasing, with the option to expand coverage or use as an awning.
Implementation Method 1
a spring roll is provided, on which a first upper cloth 3 and a second lower cloth 4 are wrapped together
Implementation Method 2
The function of said sticks 6, 7 is not only that of maintaining both cloths 3, 4 stretched out, but also, as will be seen in the following, that of ensuring the correct positioning of the cloths themselves
