Solution Overview
Problem
Conventional laundry treatment apparatuses face issues such as wrinkles in laundry after drying, damage from frequent washing, and high energy consumption due to motor operation for drum rotation. Additionally, the fixed position of the presser limits its functionality.
Innovation Solution
A laundry treatment apparatus with a removably mounted presser that can be moved to efficiently remove wrinkles and sharpen creases, while also reducing thickness to facilitate movement within the apparatus. The presser includes a support part, a hanger hook, and a press part hingedly connected to apply pressure to the laundry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the presser is fixedly mounted to the door, then the structure is simple and stable, but the position of the presser cannot be moved, reducing adaptability
Solution Approach 1:
The presser is designed with a movable mounting structure that allows it to be repositioned along the door assembly. The presser can be moved between different positions (e.g., first position for pressing laundry against the door, second position for retracting) while maintaining stable operation at each position, thus resolving the contradiction between adaptability and device complexity.
2Ease of manufacture
If a rotary drum is used for washing and drying, then washing and drying functions are achieved, but wrinkles occur in laundry and energy consumption is high
Solution Approach 1:
The invention extracts the pressing function from the traditional rotary drum system. Instead of using a rotating drum that causes wrinkles and high energy consumption, the patent introduces a separate presser assembly that can be positioned against the door to press laundry flat after drying, thereby eliminating the harmful effects while maintaining the washing and drying functionality.
3Length of moving object
If the presser thickness is reduced, then the presser can be efficiently moved within the inner space, but the pressing force may be compromised
Solution Approach 1:
The presser is designed with localized pressure application features. Instead of distributing force over a large thin surface, the presser concentrates pressing force at specific contact points or areas where laundry needs to be pressed. This allows the presser to maintain adequate thickness for structural integrity and pressing force while still being movable within the limited inner space of the appliance.
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 performs washing, drying, deodorization, sterilization, and wrinkle removal, allowing for flexible positioning of the presser to enhance crease formation and reduce energy consumption by minimizing motor operation.
Implementation Method 1
a press part hingedly connected to the support part to apply pressure to the opposite surface of laundry
