Steam Laundry Treatment With Water Softener Maintenance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry drying machines fail to completely remove wrinkles from laundry, necessitating an additional ironing process, and there is a need for an apparatus that can conveniently remove wrinkles during storage and use.
Innovation Solution
A laundry treating apparatus incorporating a steam generator, water softening member, and control unit that displays the replacement or regeneration time of the water softening member, allowing for effective wrinkle removal and maintenance of the steam generator's efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional drying machine is used to dry laundry, then laundry can be dried, but wrinkles on laundry are not completely removed
Solution Approach 1:
The patent applies parameter changes by controlling temperature and humidity conditions during the drying process to optimize wrinkle removal. The drying machine adjusts thermal parameters to create conditions that prevent wrinkle formation while maintaining drying effectiveness.
Solution Approach 2:
The patent implements periodic action through cyclic tumbling motion of the drum combined with periodic steam injection. This periodic mechanical action and steam treatment work together to gradually remove wrinkles throughout the drying cycle, achieving both drying and wrinkle removal objectives.
2Reliability
If additional ironing process is applied to remove wrinkles, then wrinkle removal is achieved, but processing time and complexity increase
Solution Approach 1:
The patent merges the drying function and wrinkle removal function into a single integrated process. By combining steam injection, controlled heating, and periodic tumbling within the same drying cycle, the machine eliminates the need for separate ironing operations, saving time and simplifying the overall process.
Solution Approach 2:
The patent applies preliminary action by removing wrinkles during the drying process itself, before the laundry is removed from the machine. The steam and tumbling actions prepare the laundry in a wrinkle-free state during drying, eliminating the need for subsequent ironing steps.
3Reliability
If water softening member is not maintained, then steam generator efficiency decreases, but maintenance complexity increases
Solution Approach 1:
The patent implements feedback by providing a display that shows the usage time or cycle count of the water softening member. This visual feedback enables users to monitor the maintenance status and replace the softening member at appropriate intervals, ensuring steam generator efficiency without requiring complex diagnostic procedures.
Solution Approach 2:
The patent applies self-service by designing the water softening member as a user-replaceable component with clear maintenance indicators. Users can independently monitor and maintain the softening member based on displayed information, eliminating the need for professional service intervention and simplifying the maintenance process.
