Movable Presser for Laundry Wrinkle Removal Without Drum Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses face issues such as wrinkles in laundry, damage from frequent washing, and high energy consumption due to motor operation, and a fixed presser position limits flexibility in wrinkle removal.
Innovation Solution
A laundry treatment apparatus with a removably mounted presser that can be moved, designed to apply pressure and remove wrinkles, featuring a hinge structure and locking mechanism for efficient positioning within the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a presser is fixedly mounted to a door, then the structure is simple and stable, but the position of the presser cannot be moved, reducing flexibility
Solution Approach 1:
The presser is transformed from a fixed mounting to a movable mounting system. The presser can be positioned at different locations within the drying chamber and moved freely, converting a static structure into a dynamic one that adapts to different laundry items and user needs.
Solution Approach 2:
The presser is separated from the door structure and mounted independently on the drying chamber wall. This segmentation allows the presser to be repositioned independently of the door, enabling flexible placement while maintaining structural simplicity through modular design.
2Productivity
If a rotary drum is used for washing and drying, then the apparatus can perform multiple functions, but energy consumption is high due to motor operation
Solution Approach 1:
The rotary drum is completely removed from the apparatus. The washing and drying functions are achieved without a rotating drum by using a stationary drying chamber with steam injection and a presser, eliminating the need for a motor and significantly reducing energy consumption.
Solution Approach 2:
The mechanical rotary drum system is replaced with a stationary chamber system that uses steam and mechanical pressing. The drying function is achieved through steam injection and thermal convection rather than mechanical rotation, and wrinkle removal is achieved through a presser instead of drum tumbling.
3Adaptability or versatility
If a presser with large thickness is used, then the presser structure is robust, but the position of the presser cannot be efficiently moved in the inner space
Solution Approach 1:
The presser is designed with a thin profile that enables easy movement and repositioning within the limited space of the drying chamber. The reduced thickness allows the presser to be efficiently moved to different locations without occupying excessive space.
4Ease of operation
If conventional washing methods are used, then laundry can be cleaned, but wrinkles remain and laundry cannot be worn immediately
Solution Approach 1:
The presser is positioned and activated during the final stage of the drying cycle to remove wrinkles before the laundry is removed from the apparatus. This preliminary wrinkle removal action ensures that laundry is ready for immediate wear without requiring additional ironing or folding.
