Laundry treating apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses face challenges in reducing volume, leading to inefficient space usage when multiple units are required, and experience vibration issues when operated in stacked configurations.
Innovation Solution
A laundry treating apparatus comprising multiple units for washing and drying, where the second treating apparatus is only operational if the third drying unit is mounted, with a power controller that adjusts current supply based on a predetermined reference amount to minimize vibration and optimize energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple laundry treating apparatuses are arranged in parallel to provide different functions (washing and drying), then the laundry treating functions are improved, but the space efficiency is worsened
Solution Approach 1:
The patent transitions from horizontal parallel arrangement to vertical stacking configuration. The drying apparatus is positioned above the washing apparatus, utilizing the vertical dimension to provide multiple laundry treating functions while reducing the floor space occupied by the system.
Solution Approach 2:
The patent implements a nested configuration where the drying apparatus is stacked on top of the washing apparatus. This nesting arrangement allows the drying drum to be positioned within the vertical space above the washing drum, maximizing space utilization.
2Volume of stationary object
If multiple laundry treating apparatuses are stacked vertically to reduce space, then the volume efficiency is improved, but vibration occurs when operated simultaneously
Solution Approach 1:
The patent implements preliminary anti-action by using the upper drying apparatus to counterbalance the vibration generated by the lower washing apparatus. The drying drum's rotation creates opposing vibrational forces that cancel out the washing drum's vibration, preventing harmful vibrations from being transmitted to the building structure.
Solution Approach 2:
The patent applies the anti-weight principle by positioning the drying apparatus as a counterbalancing mass above the washing apparatus. The drying drum serves as a counterweight that generates opposing centrifugal forces to neutralize the vibration produced by the washing drum during operation.
3Adaptability or versatility
If the lower washing apparatus is operated without the upper drying apparatus mounted, then the adaptability is improved, but vibration is increased
Solution Approach 1:
The patent implements dynamics by making the operational status of the washing apparatus dependent on the presence of the drying apparatus. The system dynamically adjusts its behavior based on whether the upper drying apparatus is mounted, allowing flexible operation modes while maintaining vibration control when both units are present.
Solution Approach 2:
The patent uses feedback mechanisms to detect whether the drying apparatus is properly mounted on the washing apparatus. Based on this feedback information, the control system determines whether to permit operation of the washing apparatus, ensuring that vibration-causing operations only occur when the counterbalancing drying apparatus is in place.
