Laundry Presser Assembly for Wrinkle Removal and Crease Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses face challenges in effectively deodorizing and removing wrinkles from laundry when it is placed in a drum while wrinkled, as this can hinder the deodorization process and require additional ironing to form creases, and they lack a device to form creases during washing or drying.
Innovation Solution
A laundry treating apparatus with a receiving space that allows laundry to be supported in a spread state, incorporating a supply device for heated air and steam, and a presser with a support and compression unit to fix creases using steam and heated water, ensuring laundry is straight and preventing wrinkles during treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laundry is placed in a drum while wrinkled, then the washing process can proceed, but the deodorization effectiveness deteriorates and additional ironing is required
Solution Approach 1:
The presser unit is activated during the washing cycle to preliminarily press and straighten the laundry before the drying phase. This preliminary pressing action prevents wrinkles from forming and ensures the laundry is in an optimal state for deodorization, eliminating the need for post-washing ironing and improving deodorization effectiveness.
Solution Approach 2:
A presser unit with compression and heating elements is introduced as an intermediary device between the washing drum and the drying phase. This presser unit applies mechanical compression and thermal energy to the laundry, straightening wrinkles and preparing the fabric surface for effective deodorization without requiring separate ironing operations.
2Manufacturing precision
If a presser unit with compression and heating elements is added, then creases can be formed and wrinkles removed, but the device complexity increases
Solution Approach 1:
The presser unit combines multiple functions into a single integrated assembly: mechanical compression through pressing elements, thermal processing through heating elements, and moisture application through steam or water spray. This merging of functions achieves precise crease formation and wrinkle removal without requiring separate devices for each operation, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The presser unit is designed as a multi-functional component that can perform compression, heating, and moisture application simultaneously or sequentially. This universal design allows a single device to handle multiple laundry treatment tasks (wrinkle removal, crease formation, deodorization preparation) without proportionally increasing system complexity.
3Device complexity
If laundry is not straightened during washing, then the washing process is simpler, but additional ironing is required after washing
Solution Approach 1:
The presser unit operates continuously during the washing and drying cycles, maintaining laundry straightness throughout the treatment process. This continuous pressing action ensures that wrinkles are prevented from forming in the first place, eliminating the need for discontinuous post-washing ironing operations and reducing total processing time.
Solution Approach 2:
The presser unit performs preliminary straightening and crease formation during the washing cycle itself, before the drying phase begins. This preliminary action prevents the need for subsequent ironing operations, as the laundry is already in the desired state when washing completes, thereby eliminating additional time loss.
