Laundry Presser Segmentation for Uniform Pressure Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses face issues with uneven pressure distribution, unintentional wrinkle formation, and difficulty in mounting laundry due to the presser's sequential pressure application from one side, leading to changes in the laundry's shape and position, and requiring different pivoting directions based on user handedness.
Innovation Solution
The apparatus features a sliding motion on the pants manager door with a first and second pressurizing plate, allowing uniform pressure application across the entire laundry region, facilitated by a sub-plate with fixing clips and a hinge structure for vertical pivoting, eliminating the need for user-specific pivoting direction adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a presser pressurizes laundry sequentially from one side, then the presser structure is simple, but the pressure distribution on laundry is uneven
Solution Approach 1:
The presser is divided into multiple pressurizing portions (first pressurizing portion and second pressurizing portion) that can independently pressurize different regions of the laundry simultaneously, transforming a single sequential pressurization point into multiple parallel pressurization zones to achieve uniform pressure distribution
Solution Approach 2:
The pressurizing portions are arranged in both horizontal and vertical dimensions on the door inner surface, creating a two-dimensional pressurization network that covers the entire laundry area, transitioning from one-dimensional sequential pressing to two-dimensional simultaneous pressing
2Device complexity
If a presser pressurizes laundry from one side, then the presser mechanism is simple, but unintentional wrinkles occur
Solution Approach 1:
Multiple pressurizing portions are distributed across the door inner surface to pressurize different regions of the laundry simultaneously, preventing the formation of unintentional wrinkles by ensuring uniform pressure across the entire laundry area
Solution Approach 2:
Each pressurizing portion is positioned to correspond with specific regions of the laundry, providing localized pressure exactly where needed to maintain the intended wrinkle pattern and prevent unwanted wrinkles in other areas
3Ease of operation
If laundry is pressurized sequentially from one side, then the presser operation is simple, but laundry position changes
Solution Approach 1:
Laundry is mounted on the door inner surface before the door is closed, and multiple pressurizing portions are pre-positioned to correspond with the laundry regions, so that when the door closes, uniform pressure is automatically applied across all laundry areas simultaneously, preventing position changes
Solution Approach 2:
The door serves multiple functions: it acts as both the closure for the treating chamber and as the mounting surface for the pressurizing portions, integrating the pressing function into the existing door structure without requiring separate complex positioning mechanisms
4Device complexity
If a single pressurizing point is used, then the device structure is simple, but the pressurized region is limited
Solution Approach 1:
The pressurizing function is segmented into multiple independent pressurizing portions distributed across the door inner surface, with each portion responsible for pressurizing a specific region of the laundry, collectively covering the entire laundry area
Solution Approach 2:
Pressurizing portions are arranged in both horizontal and vertical dimensions on the door, expanding the pressurized region from a single point to a comprehensive two-dimensional coverage area that encompasses the entire laundry
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 solution effectively reduces unintentional wrinkles, uniformly presses laundry, and ensures even pressure distribution without requiring user-specific pivoting direction settings, enhancing the laundry treatment process.
Implementation Method 1
