Solution Overview
Problem
Conventional washing machines are unable to effectively utilize minute bubble water, which contains microbubbles and nanobubbles, to enhance cleaning efficiency.
Innovation Solution
A washing machine design that includes a minute bubble generator to produce microbubbles and nanobubbles, integrating these into the wash water path, allowing for controlled mixing with detergent to improve cleaning capacity through surfactant interaction and dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If minute bubble generator is integrated into the water path, then cleaning capacity is enhanced, but device complexity increases
Solution Approach 1:
The patent combines the minute bubble generator with the existing water feeding case and water paths, integrating multiple functions (water storage, detergent mixing, and bubble generation) into a unified structure. This merging approach enhances cleaning capacity while minimizing the increase in device complexity by utilizing existing components.
Solution Approach 2:
The water feeding case is designed to serve multiple purposes: storing water, mixing with detergent, and serving as a conduit for the minute bubble generator. This multi-functionality allows the system to achieve enhanced cleaning capacity without proportionally increasing device complexity, as existing components perform multiple roles.
2Productivity
If minute bubble water path is added, then washing effectiveness is improved, but device complexity increases
Solution Approach 1:
The water supply system is segmented into distinct paths: a tap water path and a minute bubble water path. This segmentation allows the minute bubble water to be delivered separately and directly to the wash tub, improving washing effectiveness while keeping each path relatively simple in structure.
Solution Approach 2:
The minute bubble generator acts as an intermediary device that transforms regular water into minute bubble water within the existing water path structure. This intermediary approach allows the system to achieve improved washing effectiveness without requiring a complete redesign of the water supply system.
3Productivity
If controlled mixing with detergent is implemented, then cleaning efficiency is enhanced, but device complexity increases
Solution Approach 1:
The system prepares minute bubble water in advance within the water feeding case before it is delivered to the wash tub. This preliminary action of generating bubbles and mixing with detergent beforehand allows for controlled mixing that enhances cleaning efficiency while using the existing water feeding case structure, thereby limiting the increase in device complexity.
