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 usage, as they require full soaking of clothes.
Innovation Solution
A front-loading washing machine design featuring a tub with an access port that can be moved up and down within the cabinet, driven by a mechanism that allows the access port to adjust between washing and non-washing positions, reducing the need for users to stoop and minimizing water usage by allowing clothes to be washed with a smaller amount of water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the access port is fixed at a lower position for washing clothes, then washing function is improved, but user convenience deteriorates due to need to stoop and crouch
Solution Approach 1:
The access port is made movable rather than fixed, allowing it to dynamically adjust between a lower washing position and an upper loading position. The tub can rotate around a transverse shaft, enabling the access port to move between positions automatically or manually, resolving the contradiction between fixed washing functionality and user convenience.
2Ease of operation
If the tub is made movable to adjust access port position, then user convenience is improved, but device complexity increases due to additional driving mechanism
Solution Approach 1:
The tub rotation is implemented as a periodic action that can be activated at specific stages of the washing cycle. The driving mechanism (motor or hydraulic cylinder) operates periodically to rotate the tub to the loading position, then returns it to the washing position, providing convenience only when needed rather than continuously, thus reducing overall system complexity.
Solution Approach 2:
The system can automatically rotate the tub to the loading position when the washing cycle is completed or paused, without requiring manual intervention. The driving mechanism is controlled by the washing machine's control system to autonomously adjust the access port position, making the system self-serving and reducing the need for complex manual control mechanisms.
3Productivity
If full soaking is used for washing clothes, then washing effectiveness is improved, but water consumption increases
Solution Approach 1:
Instead of requiring complete submersion of clothes in water for the entire washing cycle, the system uses partial soaking combined with periodic tumbling action. The tub rotation allows clothes to be partially submerged and then lifted, creating a washing action that is effective but uses less water than complete soaking, achieving productivity with reduced substance loss.
