Washing machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines lack a dedicated space for hand-washing, requiring additional water and separate processes outside the machine, making it difficult to effectively remove ingrained dirt or partial stains from clothes.
Innovation Solution
A washing machine design incorporating a sub-washing unit that can be separated from the main washing space, allowing for hand-washing within the machine, with a movable sub-washing unit and a water supply system to manage wash water efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a washing machine has a fixed tub and rotary drum structure, then the washing machine can perform automated washing, but it cannot provide a space for hand-washing or separate washing
Solution Approach 1:
The washing machine is divided into two independent washing spaces: a main washing space with a fixed tub and rotary drum for automated washing, and a sub-washing space with a separable sub-washing unit for hand-washing. This segmentation allows the machine to perform both automated and manual washing functions simultaneously, resolving the contradiction between washing versatility and structural complexity.
Solution Approach 2:
The sub-washing unit is designed to be movable and separable from the main washing space. It can be detached and reattached as needed, allowing the washing machine to dynamically adapt between different washing modes (automated only, hand-washing only, or both simultaneously), thereby increasing versatility without permanently complicating the structure.
2Loss of substance
If hand-washing is performed outside the washing machine, then dedicated hand-washing space is not required, but additional wash water is required and water cannot be reused
Solution Approach 1:
The sub-washing unit is integrated into the washing machine structure, merging the hand-washing function with the main washing system. Both the main washing space and sub-washing space share the same water supply and drainage systems, allowing wash water to be reused across both spaces and eliminating the need for separate water sources, thus reducing water consumption while providing integrated hand-washing capability.
3Adaptability or versatility
If a sub-washing unit is added to the washing machine, then hand-washing capability is provided, but the device complexity increases
Solution Approach 1:
The sub-washing unit is designed as a multi-functional component that can serve multiple purposes: it provides hand-washing capability, can be detached for external use, and integrates with the main washing system for shared water management. This universal design allows a single added component to provide multiple benefits, reducing the relative impact of increased complexity.
Solution Approach 2:
The sub-washing unit is nested within the overall washing machine structure, fitting into the available space without requiring a completely separate external unit. This nesting approach minimizes the increase in overall device complexity while still providing the desired hand-washing functionality.

AI summary
Disclosed herein is a washing machine including a main body having a washing space and an opening through which clothes are inserted and withdrawn into and from the washing space, a door to open and close the opening, and a sub-washing unit to form a sub-washing space separate from the washing space and separably provided from the door. By such configuration, sub-washing may be efficiently performed, and space utilization may be improved.
