Garment Pressing Assembly for Uniform Vertical Laundry Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses fail to uniformly press and stabilize clothing items, leading to deformation, displacement, and excessive creasing due to their drum-based design, which limits their ability to effectively deodorize and remove wrinkles.
Innovation Solution
A laundry treating apparatus with a cabinet and a pressing portion that rotates in a height direction to prevent deformation, featuring a holding portion with a fixing unit and a support unit to immobilize the clothing item, allowing for controlled pressing over an extended area without displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressing portion rotates in a width direction to press the clothing item, then the pressing operation can be performed, but the clothing item is pressed non-uniformly and deformation or displacement occurs
Solution Approach 1:
The pressing portion is inverted from rotating in the width direction to rotating in the height direction. This inversion changes the pressing trajectory from side-to-side to top-to-bottom, allowing the pressing portion to follow the length direction of the clothing item and achieve uniform pressing across the entire garment surface.
Solution Approach 2:
The rotation direction of the pressing portion is changed from the width dimension to the height dimension. By rotating along the height direction, the pressing portion can traverse the entire length of the clothing item vertically, ensuring uniform pressure distribution and preventing lateral displacement that occurs with width-direction rotation.
2Ease of operation
If the pressing portion presses the clothing item sequentially from one side surface to the other, then the pressing operation can be performed, but relatively high pressure is applied to parts close to the rotation axis while relatively low pressure is applied to parts far from the axis
Solution Approach 1:
The pressing motion is inverted from sequential side-to-side pressing to simultaneous top-to-bottom pressing. By rotating in the height direction, the pressing portion can apply pressure uniformly across different vertical levels of the clothing item, eliminating the pressure gradient caused by distance from the rotation axis.
3Device complexity
If the clothing item is held on the holding portion without additional fixing, then the holding structure is simple, but the clothing item may move out of place during pressing
Solution Approach 1:
The support unit preliminarily supports the clothing item at its lower end before pressing begins. This preliminary positioning prevents the clothing item from moving or deforming during the pressing operation, ensuring it remains stable and properly positioned throughout the process.
4Device complexity
If the pressing portion is configured to rotate in a width direction, then the pressing mechanism is simple, but the pressing portion can only press a specific area of the clothing item
Solution Approach 1:
The pressing mechanism rotates in the height direction instead of the width direction, enabling it to cover the entire vertical length of the clothing item. This dimensional change allows a single pressing portion to press all areas of the garment from top to bottom, significantly increasing area coverage without adding complexity.
