Mesh-Jig Drying Tube for Garment Shrinkage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying systems for clothes, such as air bags made of plastic sheets, shrink due to repeated use of hot air, rendering them unusable, especially during the drying process after washing and spinning-dry, and require frequent replacement or delivery from laundries, imposing economic and convenience burdens.
Innovation Solution
A drying system comprising an expandable drying tube made of synthetic resin, a jig with a mesh fabric to restrain expansion, and a fixing part with Velcro and elastic components to prevent clothes from shrinking during drying, along with a method involving air injection and fabric softener use to maintain garment shape and prevent stretching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hot air is injected into a plastic sheet air bag to smooth clothes, then the clothes can be smoothed out, but the air bag shrinks due to repeated use and hot air exposure, rendering it unusable
Solution Approach 1:
The patent changes the material parameter from plastic sheet to knitted fabric, and changes the thermal parameter from hot air to cold air, which prevents the shrinking issue while maintaining the smoothing function
Solution Approach 2:
The invention uses a composite structure combining knitted fabric with an expandable ball, creating a new material system that maintains shape stability while providing expansion capability for clothes smoothing
2Productivity
If a plastic sheet air bag is used for drying clothes, then clothes can be dried, but the air bag cannot be used during the drying process immediately after washing and spinning-dry due to shrinkage
Solution Approach 1:
The patent changes the temperature parameter from hot air to cold air, which eliminates the thermal shrinkage problem and allows the drying bag to be used immediately after washing without replacement
Solution Approach 2:
The invention creates a new version of the drying bag using knitted fabric that copies the functional form of the plastic sheet bag but with improved material properties that prevent shrinkage
3Reliability
If an expandable drying tube is used to maintain clothes shape during drying, then clothes shrinkage is prevented, but the system requires additional components (jig, fixing part) to maintain the expanded shape
Solution Approach 1:
The patent merges the drying tube and jig into a single integrated knitted fabric structure with embedded expandable balls, eliminating the need for separate fixing parts while maintaining shape control functionality
Solution Approach 2:
The knitted fabric drying tube serves multiple functions simultaneously: it provides the drying environment, maintains clothes shape through embedded expandable balls, and eliminates the need for separate fixing mechanisms
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
The system effectively prevents clothes from shrinking during the drying process by maintaining the expanded shape of the drying tube within the mesh fabric jig, ensuring consistent garment size and reducing the need for frequent replacements or laundry services.
Implementation Method 1
a drying tube (20) of which the volume is expandable by air injected through an air injection part (10)
Implementation Method 2
a jig (30) for stopping the expansion after the drying tube (20) is expanded to prescribed shape and size
Implementation Method 3
a fixing part (50) for fixing clothes worn on the drying tube (20) not to be shrunk while being dried

AI summary
Disclosed herein are drying system and method for restoring clothes shrunk after washing and drying of the clothes. The clothes drying system includes: an air injection part for injecting air into the drying system; a drying tube of which the volume is expandable by the air injected through the air injection part; a jig put on the outer surface of the drying tube; and a fixing part attached to the clothes and fixing the clothes and jig so that the clothes put on the outer surface of the jig is not shrunk while being dried.
