Movable Tub Front-Loading Washer for Easier Loading and Low Water Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front-loading washing machines require users to bend and squat for loading and unloading, making them inconvenient, especially for special populations, and have poor water-saving effects due to the need for complete immersion of laundry.
Innovation Solution
A front-loading washing machine with a driving mechanism that allows the access port to move up and down, enabling convenient loading and unloading without bending and reducing water usage by allowing only a small amount of water for washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the access port is fixed at a lower position for effective washing, then washing performance is improved, but user convenience deteriorates due to bending and squatting requirements
Solution Approach 1:
The access port is made dynamically adjustable in position through a driving mechanism that allows it to move between a lower washing position and an upper loading position. This resolves the contradiction by enabling the access port to adapt its position based on operational requirements rather than being fixed at a single location.
Solution Approach 2:
The access port's position is changed along the vertical dimension, moving between upper and lower positions. This vertical movement allows the system to optimize for either washing performance (lower position) or user convenience (upper position) as needed, adding a spatial dimension to resolve the contradiction.
2Ease of operation
If the access port is positioned for easy loading and unloading, then user convenience is improved, but washing performance deteriorates due to insufficient water immersion
Solution Approach 1:
The access port position is dynamically adjusted to a lower position during the washing cycle to ensure proper water immersion and washing performance, while being positioned higher during loading/unloading operations for user convenience. This temporal separation of positions resolves the contradiction.
3Device complexity
If a fixed access port design is used, then device complexity is reduced, but adaptability deteriorates due to inability to accommodate different user needs and washing requirements
Solution Approach 1:
The access port system incorporates a driving mechanism that enables dynamic position adjustment between upper and lower positions. This adds adaptability for different operational modes (loading vs. washing) while maintaining relatively simple structural implementation through the use of a straightforward mechanical actuation system.
