Clothing treatment device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry treating apparatuses are limited in deodorizing and removing wrinkles due to the use of a drum and driver, leading to inefficient crease removal, uneven pressure application, and displacement of laundry items, especially with partitioned areas like pants, resulting in unwanted creases and incomplete refresh processes.
Innovation Solution
A laundry treating apparatus with a separate steam and hot wire system integrated into a door assembly, allowing for independent operation of a second laundry treating chamber within the door, which includes a partitioned space for uniform pressure application and steam/hot air supply to each area, preventing displacement and ensuring intended crease formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single drum structure is used for laundry treatment, then the device complexity is reduced, but the productivity is reduced because only one laundry item can be treated at a time
Solution Approach 1:
The laundry treating apparatus is divided into two independent chambers: a first laundry treating chamber (drum type) and a second laundry treating chamber (door assembly type). Each chamber can independently treat laundry items, allowing parallel processing and improving productivity while maintaining reasonable device complexity through modular design.
2Device complexity
If a single press plate is used without partition members, then the device complexity is reduced, but the manufacturing precision is reduced because uniform pressure cannot be applied to partitioned areas
Solution Approach 1:
The press plate is divided into multiple pressing units by partition members, with each pressing unit independently pressing a specific partitioned area of the laundry item. This segmentation enables uniform pressure distribution across different regions (e.g., left and right pant legs) while maintaining a relatively simple overall press mechanism structure.
Solution Approach 2:
Each pressing unit is equipped with independent pressing capability, allowing different local areas of the laundry item to receive appropriate pressure. The partition members create localized pressing zones that can be independently controlled, ensuring precise pressure application to specific regions without affecting other areas.
3Device complexity
If the crease removal module is formed at one side of the door headed for the treating chamber, then the device complexity is reduced, but the adaptability is reduced because the module cannot be used while laundry is being treated in the treating chamber
Solution Approach 1:
The laundry treating apparatus is segmented into two independently operable chambers: the first laundry treating chamber accessible through the cabinet door, and the second laundry treating chamber (crease removal module) formed within the door assembly itself. This allows the crease removal module to operate independently while the main treating chamber is in use, enhancing adaptability without significantly increasing overall device complexity.
4Device complexity
If the press plate presses laundry from one side surface, then the device complexity is reduced, but the manufacturing precision is reduced because pressure is not applied uniformly to all areas
Solution Approach 1:
The press plate is divided into multiple pressing units separated by partition members, enabling simultaneous pressing of multiple partitioned areas from opposite sides. This segmentation allows uniform pressure application to different regions of the laundry item while maintaining a relatively simple pressing mechanism that rotates to press both surfaces.
