Laundry Tub Drain Hose Layout for Drain Height and Space Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laundry treating devices face challenges in providing sufficient water drain height within limited inner spaces, especially when a predetermined structure is present in the lower portion, which can lead to inefficient water drainage and residual dirt.
Innovation Solution
The design incorporates a water drain hose connected to the side surface of a recessed lower water holding part in the tub, with a movable housing and casing configuration that allows for optimal positioning of the tub and water drain pump, ensuring a sufficient water drain height and preventing backward flow of water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined structure is provided in the lower portion of the laundry treating device, then the device functionality is enhanced, but the water drain height becomes insufficient
Solution Approach 1:
The water drain hose is configured to extend in a lateral direction (horizontal dimension) from the tub bottom rather than vertically downward. This dimensional change allows the hose to achieve sufficient drainage height while accommodating predetermined structures in the lower vertical space of the device.
2Productivity
If the water drain hose is positioned to ensure sufficient drain height, then water drainage efficiency is improved, but the inner space utilization becomes inefficient
Solution Approach 1:
The drainage system transitions from a vertical hose arrangement to a lateral extension configuration. This allows the water drain hose to maintain sufficient height for efficient drainage while utilizing the horizontal inner space that would otherwise be wasted, achieving both drainage efficiency and space optimization.
3Volume of moving object
If the tub position is lowered to optimize inner space, then space utilization is improved, but the water drain height becomes insufficient
Solution Approach 1:
Instead of relying on vertical height from a raised tub position, the water drain hose extends laterally from the tub bottom. This dimensional shift allows the tub to be positioned lower for optimal space utilization while the lateral hose extension maintains sufficient drainage height independent of tub elevation.
