Sliding-Groove Tub Assembly for Replaceable Washing Machine Tubs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional household washing machines have fixedly connected inner and outer tubs, making them difficult to disassemble and clean, unable to accommodate different fabric types, and inefficient in water and energy usage due to a single fixed tub capacity.
Innovation Solution
An integrated washing and spinning tub design where the water holding tub and spinning tub are connected in a sliding groove mode, allowing for easy assembly and disassembly without professional tools, and a spring telescopic support for adaptable tub sizes, enabling multiple tub configurations for varied washing needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the inner and outer tubs are fixedly connected, then the structural stability is improved, but the ease of operation for cleaning and maintenance deteriorates
Solution Approach 1:
The washing machine tub system is segmented into an inner tub and an outer tub that can be separated from each other. The inner tub can be independently removed from the outer tub for cleaning purposes, while maintaining structural stability during operation through proper connection mechanisms.
Solution Approach 2:
The connection between the inner tub and outer tub transitions from a static fixed connection to a dynamic connection that allows separation. The inner tub can be easily inserted and removed from the outer tub, providing both stability during use and accessibility for cleaning.
2Device complexity
If a single fixed tub is used, then the device complexity is reduced, but the adaptability for different fabric types deteriorates
Solution Approach 1:
The tub system is divided into separable inner and outer tubs, allowing users to select appropriate combinations for different washing needs. This segmentation enables adaptability for different fabric types while maintaining relatively simple device structure.
Solution Approach 2:
The separable tub design provides multi-functionality, allowing the same washing machine to handle different fabric types and washing requirements through different tub configurations, achieving universality without significant complexity increase.
3Device complexity
If the tub capacity is fixed, then the device complexity is reduced, but the loss of energy and water efficiency deteriorates
Solution Approach 1:
The tub system is segmented into removable inner tub and outer tub combinations, allowing users to adjust the effective washing capacity by removing the inner tub when washing small loads. This reduces water and energy consumption for small loads while maintaining simple device structure.
Solution Approach 2:
The tub capacity transitions from a fixed static value to a dynamic adjustable value. Users can change the effective capacity by removing or keeping the inner tub based on load size, optimizing energy and water efficiency without complicating the device.
