Front-loading washing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front-loading washing machines are inconvenient for users, particularly elderly individuals, due to the need to stoop and crouch for loading and unloading clothes, and they are inefficient in water conservation as they require full soaking of clothes in water.
Innovation Solution
A front-loading washing machine with a tub that can move up and down, allowing the access port to adjust between non-washing and washing positions, driven by a mechanism that includes a longitudinal pushrod, transverse shaft, and support frame, enabling easy access and reducing water usage through controlled water levels and a midway clothes-adding feature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the access port is fixed at the front panel, then the structure is simple, but users must stoop and crouch to load/unload clothes causing inconvenience
Solution Approach 1:
The access port is made movable rather than fixed, allowing it to switch between different positions (upper for loading, lower for washing) to adapt to different operational requirements, thereby improving user convenience without requiring permanent structural changes
Solution Approach 2:
The access port is moved from a fixed two-dimensional position on the front panel to a three-dimensional movable position that can change height, allowing users to access clothes at different vertical levels without stooping or crouching
2Reliability
If clothes are fully soaked in water for washing, then washing effectiveness is improved, but water consumption increases significantly
Solution Approach 1:
Instead of fully submerging clothes in water, the invention uses partial immersion where only the necessary portion of clothes contacts water, achieving adequate washing effectiveness while significantly reducing water consumption
Solution Approach 2:
The washing method changes from full soaking to controlled partial immersion, altering the water-clothes contact parameter to reduce water usage while maintaining washing effectiveness through the tumbling action and strategic water application
3Loss of substance
If the access port is positioned at the lower edge during washing, then water conservation is improved, but user access becomes difficult
Solution Approach 1:
The access port dynamically changes position based on the operational phase: located at the lower edge during washing to conserve water, and movable to the upper edge during loading/unloading to improve user access, thus resolving the contradiction between water conservation and accessibility
