Air-Stretched Laundry Support for Wrinkle-Free Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses are unable to effectively remove wrinkles from laundry due to the rotation of laundry within a drum without proper straightening, resulting in wrinkled laundry.
Innovation Solution
A laundry treatment apparatus featuring a support body, an air supply unit for providing air to hung laundry, and a tensile force provision unit that separates and spaces out the inner circumferential surfaces of the laundry, using air to generate tensile force and prevent wrinkle formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If laundry is rotated in a drum during washing and drying, then the laundry treatment process is simplified and automated, but the laundry becomes wrinkled and cannot be straightened
Solution Approach 1:
The patent applies preliminary action by providing a tensile force to the laundry before and during the drying process to prevent wrinkle formation. The tensile force provision unit applies stretching force in advance to keep the laundry straightened, so that when drying occurs, the laundry maintains a smooth shape without becoming wrinkled from drum rotation.
2Productivity
If a drum structure is used for washing and drying laundry, then the apparatus can handle laundry efficiently, but it cannot provide tensile force to straighten and remove wrinkles from laundry
Solution Approach 1:
The patent merges the drum structure for efficient laundry handling with a separate tensile force provision unit. The combination type laundry treatment apparatus integrates both the drum rotation function for processing efficiency and the tensile force application function for wrinkle removal, allowing both functions to work together in the same apparatus.
Solution Approach 2:
The tensile force provision unit acts as an intermediary between the drum structure and the laundry. It provides the necessary tensile force to straighten the laundry without interfering with the drum's rotation function, mediating between the mechanical drum action and the laundry to achieve both efficient processing and wrinkle-free results.
3Device complexity
If laundry is hung to dry without support, then the drying process is simple, but the laundry remains wrinkled and requires ironing
Solution Approach 1:
The patent applies self-service by having the tensile force provision unit automatically apply stretching force to the laundry during the drying process. The system serves itself by integrating the wrinkle removal function into the drying process, so the laundry is automatically straightened and dried without requiring separate ironing or manual intervention.
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 apparatus effectively removes wrinkles from laundry without the need for ironing, both for wet and dry garments, by using air to unfold and straighten the fabric, ensuring that laundry is dried and smoothed without creases.
Implementation Method 1
an air supply unit for supplying air into laundry hung on the support body
Implementation Method 2
a tensile force provision unit for providing a tensile force to the laundry hung on the support body
