Moving Hanger Bar Structure for Compact Laundry Steam Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses are inefficient in minimizing space and effectively removing wrinkles and unpleasant smells from laundry without damaging fabrics or increasing power consumption.
Innovation Solution
A laundry treating apparatus with a treating chamber, a supply device for heated air or steam, and a hanger bar with a hanger groove of varying widths to accommodate different hanger types, driven by a rotational force to improve laundry treatment efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the hanger bar is made stationary to simplify the structure, then the device complexity is reduced, but the laundry treatment efficiency decreases due to poor air circulation and steam distribution
Solution Approach 1:
The hanger bar is designed to move horizontally back and forth within the treating chamber instead of being stationary. This dynamic movement enables better circulation of heated air and steam throughout the chamber, improving laundry treatment efficiency without requiring complex additional components
Solution Approach 2:
The hanger bar's horizontal movement allows it to automatically access different regions of the treating chamber, enabling uniform exposure of laundry to steam and heated air without requiring separate mechanisms for each treatment zone
2Adaptability or versatility
If the apparatus width is increased to accommodate more components, then the functionality is improved, but the installation space requirement increases
Solution Approach 1:
The hanger bar moves horizontally along the width direction of the treating chamber, utilizing the existing spatial dimension rather than requiring additional width. This allows the apparatus to maintain a compact footprint while achieving comprehensive laundry treatment through the movement mechanism
3Adaptability or versatility
If a single-width hanger groove is used to simplify manufacturing, then the manufacturing precision requirement is reduced, but the adaptability to different hanger types decreases
Solution Approach 1:
The hanger groove features a stepped cross-section with different width portions along its length, allowing each segment to accommodate different hanger types. This localized variation in groove geometry enables universal compatibility without requiring high precision throughout the entire groove structure
Solution Approach 2:
The multi-step hanger groove design allows a single groove structure to serve multiple functions by accommodating various hanger types (different widths and configurations) within the same treating chamber, enhancing the apparatus's versatility
4Volume of moving object
If the hanger bar is positioned centrally to optimize space, then the space utilization is improved, but the accessibility for various hanger types is reduced
Solution Approach 1:
The hanger bar's horizontal movement capability allows it to dynamically access different positions within the treating chamber, maintaining optimal space utilization when stationary while providing full accessibility to various hanger types during operation
