Roller-Type Pants Press in Laundry Door for Uniform Wrinkle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses face issues such as non-uniform pressing, excessive steam and hot air usage, deformation of laundry due to uneven pressure, and inefficiencies in steam distribution, leading to crease formation and energy waste.
Innovation Solution
A roller-type pants management machine that moves vertically, applies uniform pressure, sprays steam only where needed, and operates independently of the main chamber, using wireless power supply to minimize energy consumption and prevent steam and power exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a presser presses pants by rotation on one side surface, then the pants can be pressed to remove wrinkles, but the pressure is not uniform causing deformation and position change
Solution Approach 1:
Instead of rotating the presser on one side, the invention inverts the approach by having the presser rotate around the pants (360-degree rotation), making the pants the central axis rather than the presser. This ensures uniform pressure distribution from all directions and prevents positional deformation.
Solution Approach 2:
The pressing action is segmented into multiple rotational phases around the pants, with the presser applying pressure from different angular positions. This segmentation of the pressing path ensures that no single area receives excessive pressure while all areas receive adequate pressure for wrinkle removal.
2Manufacturing precision
If steam and hot air are supplied throughout the entire treatment chamber, then wrinkles can be removed from laundry, but excessive energy is consumed
Solution Approach 1:
Steam and hot air supply is localized to specific areas where wrinkles need removal rather than supplying the entire chamber. The system provides concentrated thermal treatment to targeted regions, improving energy efficiency while maintaining effective wrinkle removal.
Solution Approach 2:
Instead of supplying steam and hot air uniformly throughout the chamber, the system applies partial action by targeting only the necessary areas. This selective supply reduces overall energy consumption while achieving the required wrinkle removal effect.
3Manufacturing precision
If a scanner applies steam and heat to laundry while moving vertically, then wrinkles can be removed, but the contact area is constant causing interference with stitch lines
Solution Approach 1:
The presser's contact area with the pants is made dynamic rather than constant. During rotation, the presser adjusts its contact characteristics to avoid fixed pressure points on stitch lines, allowing the pants to be pressed uniformly without damaging structural elements.
Solution Approach 2:
The system performs preliminary assessment of the pants structure to identify stitch line locations before pressing begins. This allows the pressing path and pressure application to be pre-planned to avoid interference with stitch lines while still achieving effective wrinkle removal.
