Dual-Axis Pressurizing Plate Design for Uniform Laundry Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses face issues with uneven pressing of laundry, unintentional wrinkles, and difficulty in forming intended creases due to the sequential and one-sided pressing mechanism, which also leads to changes in the shape and position of the laundry during the pressing process.
Innovation Solution
The apparatus incorporates a sliding and pivoting door mechanism with a first and second pressurizing plate, allowing for simultaneous and uniform pressing of the entire laundry region, with the second pressurizing plate pivoting vertically and the first plate pivoting horizontally, and includes fixing clips to secure the laundry in place, ensuring even pressure distribution and preventing shape changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single pressurizing plate presses laundry sequentially from one side, then the pressing mechanism is simple, but the pressure distribution is uneven and unintentional wrinkles occur
Solution Approach 1:
The single pressurizing plate is divided into two separate pressurizing plates (first and second) that can independently press different regions of the laundry. This segmentation allows simultaneous pressing from multiple sides, achieving uniform pressure distribution while eliminating the sequential pressing limitation of a single plate.
Solution Approach 2:
The pressing mechanism transitions from one-dimensional sequential pressing to two-dimensional simultaneous pressing. The first pressurizing plate presses from the front side while the second pressurizing plate presses from the rear side, creating a multi-directional pressing action that ensures uniform pressure across the entire laundry surface.
2Device complexity
If laundry is pressed sequentially from one side, then the mechanism is simple, but the shape and position of laundry change during pressing
Solution Approach 1:
The fixing clips are installed on the pressurizing plates before pressing begins. These clips pre-establish constraints on the laundry, preventing it from shifting or changing shape during the pressing process. This preliminary anti-action counteracts the potential instability caused by the pressing force.
Solution Approach 2:
Fixing clips are strategically positioned at specific locations on the pressurizing plates to locally constrain the laundry at critical points. This localized fixation ensures that the laundry maintains its position and shape during pressing without requiring complete immobilization, balancing stability with pressing effectiveness.
3Productivity
If a pressurizing plate covers most of the door inner surface, then pressing capacity is high, but mounting space for laundry is limited
Solution Approach 1:
The door inner surface is segmented into distinct functional zones: a mounting area for loading laundry and separate pressurizing areas for applying pressure. The pressurizing plates are designed to cover only the necessary pressing regions rather than the entire door surface, freeing up space for laundry mounting while maintaining adequate pressing capacity.
Solution Approach 2:
The pressurizing plates are designed to be movable rather than fixed, allowing them to be repositioned or removed when not in use. This dynamic design enables the mounting area to be fully accessible for loading laundry, while the pressurizing plates can be deployed to cover the required pressing areas when needed, optimizing both mounting space and pressing capacity.
