Dual-Unit Washing Machine with Segmented Detergent Supply System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines have a single washing unit, requiring multiple cycles for separate washing of clothes, which is inefficient and time-consuming, especially for small loads, and lack easy detergent supply and separation of detergents from fabric softeners or bleaching agents.
Innovation Solution
A washing machine with multiple washing units, including a top-loading and front-loading configuration, featuring separate detergent containers and a detergent supply system that prevents mixing of detergents and allows easy access and supply of detergents to the tubs, along with a pivotally supported container cover for convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single washing unit is used, then the device complexity is reduced, but the productivity decreases due to multiple washing cycles required for separate clothes
Solution Approach 1:
The washing machine is divided into multiple independent washing units (first washing unit with first tub, second washing unit with second tub) that can operate simultaneously or independently. Each washing unit has its own drum, motor, and control system, allowing separate washing of different clothes types or loads at the same time, thereby improving productivity without requiring a single complex centralized system
2Ease of operation
If detergent containers are placed in the lower portion for easy access, then the ease of operation improves, but the device complexity increases due to additional supply mechanisms
Solution Approach 1:
A detergent supply mechanism acts as an intermediary between the detergent container and the washing tub. The mechanism includes a supply hose with a valve that automatically or manually transfers detergent from the container to the tub during the washing cycle, eliminating the need for users to manually handle detergent while maintaining a manageable supply system
3Device complexity
If detergent and fabric softener are stored in the same container, then the device complexity is reduced, but the reliability decreases due to risk of mixing different detergents
Solution Approach 1:
The detergent storage system is segmented into separate containers for different types of detergents (detergent container for washing detergent, fabric softener container for softener). Each container is dedicated to a specific substance and has its own supply mechanism, preventing mixing while maintaining a relatively simple overall structure through modular design
4Stability of the object's composition
If the container cover is fixed to the housing for stable structure, then the stability is improved, but the ease of operation decreases due to difficulty in detachment and attachment
Solution Approach 1:
The container cover is designed with a dynamic attachment system that allows it to be easily detached and reattached by users. The cover may include engagement features such as clips, latches, or magnetic attachments that provide stable connection during operation but can be easily released when needed, balancing stability with operational ease

AI summary
A washing machine includes a first housing, a second housing arranged above the first housing and having a laundry inlet arranged on the top, a first tub covered by the first housing and having a first opening on the front, a second tub covered by the second housing and having a second opening on the top, and a detergent container arranged in the second housing for storing a detergent to be supplied to the first tub.
