Front-Loading Washing Machine with Movable Tub for Ergonomic Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front-loading washing machines are inconvenient to use, especially for elderly people and others who have difficulty stooping or crouching, and they are inefficient in water conservation due to the need for full water soaking.
Innovation Solution
A front-loading washing machine design featuring a tub with a movable access port driven by a mechanism that allows the port to move up and down, enabling easy loading and unloading without stooping and reducing water usage by allowing for washing with a minimal amount of water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a front-loading washing machine is used, then water conservation is improved, but ease of operation deteriorates due to the need to stoop and crouch for loading/unloading clothes
Solution Approach 1:
The tub is designed to be tiltable about a tilt axis, allowing the access port to be dynamically adjusted between a loading/unloading position (upper end) and a washing position (lower end). This dynamic repositioning enables convenient clothes loading without stooping while maintaining the water-saving front-loading washing mechanism during the washing cycle
2Loss of substance
If the access port is positioned at the lower front for washing, then water conservation is improved, but ease of operation deteriorates requiring users to stoop and crouch
Solution Approach 1:
The tub can be tilted to position the access port at different heights: at the upper end for convenient loading/unloading and at the lower end for washing. This dynamic repositioning resolves the contradiction between water conservation and ease of operation
Solution Approach 2:
The tub is tilted about a tilt axis that is perpendicular to the drum rotation axis, introducing a new degree of freedom (tilting dimension) that allows the access port to be repositioned vertically without affecting the washing function
