Solution Overview
Problem
Conventional washing machines typically have only one washing device, requiring multiple cycles for laundry separation and washing, leading to inefficient use of time and resources, especially for small loads.
Innovation Solution
A washing machine with multiple washing apparatuses, including a vertically oriented drum with a filter unit that filters foreign substances and a driving shaft flange with a reduced radial length for stable operation, allowing for efficient laundry separation and washing without the need for multiple cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a washing machine has only one washing device, then the device complexity is low, but the productivity decreases because multiple cycles are needed for laundry separation
Solution Approach 1:
The washing machine is divided into multiple independent washing apparatuses (first washing apparatus with first drum, second washing apparatus with second drum) that can operate simultaneously or independently. This segmentation allows different types of laundry to be washed in parallel, improving productivity without requiring sequential operations.
Solution Approach 2:
Each washing apparatus is designed to handle different washing needs (e.g., normal washing, delicate items, different water temperatures), making the system multi-functional. The first and second washing apparatuses can process different laundry types simultaneously, achieving both specialization and versatility.
2Volume of moving object
If the drum radius is reduced to accommodate multiple washing apparatuses, then the device complexity decreases and space is saved, but the stability of the drum operation may be affected
Solution Approach 1:
Instead of reducing the drum radius, the invention adds a new dimension by stacking washing apparatuses vertically (first drum and second drum at different heights). This dimensional change allows compact space utilization while maintaining adequate drum sizes for stable operation.
Solution Approach 2:
The washing apparatuses are nested within a common housing structure, with the first and second drums arranged one above the other. This nesting approach maximizes space utilization while preserving the structural integrity and operational stability of each drum.
3Manufacturing precision
If a filter unit is added to collect foreign substances, then the purity of washing water improves, but the device complexity increases
Solution Approach 1:
The filter unit is merged with the drum structure, forming an integrated assembly rather than a separate component. The filter is positioned within the drum, and the entire filter-drum assembly rotates together, simplifying the overall structure while maintaining effective foreign substance collection.
Solution Approach 2:
The filter unit is designed to be automatically cleaned or maintained through the washing process itself. Foreign substances are collected during normal operation, and the filter structure allows for easy access and cleaning without requiring separate maintenance systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient washing and separation of laundry in a single cycle by utilizing multiple washing apparatuses and a filter unit to collect foreign substances, while maintaining stability and efficiency with a compact driving shaft flange design.
Implementation Method 1
a filter unit disposed at an inner wall of the drum, filtering washing water flowing in a circumferential direction of the drum and discharging the washing water in an inward radial direction inside the drum
Implementation Method 2
a first valve member configured to allow the washing water flowing through the first opening to flow into the discharge portion... a second valve member configured to allow the washing water flowing through the second opening to flow into the discharge portion

AI summary
A washing machine includes a housing; a drum disposed inside the housing and including a rotation shaft that extends in a vertical direction; and a filter unit disposed at an inner wall of the drum, configured to filter washing water flowing in a circumferential direction of the drum and to discharge the washing water in a radial direction inside of the drum. Accordingly, when a water current is formed inside the drum in the circumferential direction of the drum, the filter unit is disposed inside the drum so that foreign substances in the washing water rotated in the circumferential direction of the drum can be easily filtered.
