Solution Overview

Problem

Conventional washing machines struggle to simultaneously perform a circulation function and a bubble function effectively, which limits the transfer of detergent water to laundry and compromises washing performance without damaging laundry surfaces or fibers.

Innovation Solution

The washing machine incorporates a circulation bubble unit with a unique fluid path design, including a first fluid path for circulation and a second fluid path for bubble generation, utilizing a venturi effect to introduce air and create bubbles, while an electromagnetic control valve allows for selective operation of both functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single circulating pump is used to selectively perform circulation function and bubble function, then device complexity is reduced, but the ability to simultaneously perform both functions is limited

Engineering Contradiction:
Improvepump system complexityVSAvoidsimultaneous function capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The single circulating pump is divided into two separate pumps: a circulation pump for water circulation and a bubble pump for bubble generation. This segmentation allows each pump to be optimized for its specific function while enabling simultaneous operation of both functions without increasing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The circulating pump chamber is designed with multi-functionality to serve both circulation and bubble generation purposes. The chamber structure includes a circulation pump chamber and a bubble pump chamber that can operate independently or together, allowing the system to adapt to different washing modes while using a unified pump housing.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If circulation function is performed to transfer detergent water to laundry, then washing efficiency is improved, but uniform infiltration of wash water throughout laundry is compromised

Engineering Contradiction:
Improvedetergent water transfer efficiencyVSAvoidwash water distribution uniformity
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

Bubbles are introduced as an intermediary substance to facilitate uniform distribution of detergent water. The bubble generating unit creates bubbles that rise through the laundry, carrying detergent water and enabling it to infiltrate uniformly throughout the laundry load, thereby complementing the circulation pump's water transfer function.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system utilizes pneumatic principles by introducing air bubbles into the water-detergent mixture. The bubble pump draws air from the water tub and mixes it with detergent water to create bubbles, which then rise through the laundry to achieve uniform infiltration, combining hydraulic circulation with pneumatic distribution.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Reliability

If bubble function is used to enhance washing power, then washing performance is improved, but device complexity increases due to additional bubble generating unit

Engineering Contradiction:
Improvewashing performanceVSAvoidbubble generating structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bubble generating unit is merged with the circulation pump chamber, sharing the same housing and operational control system. The bubble pump and circulation pump operate within a unified chamber structure, reducing overall device complexity while maintaining enhanced washing performance through the addition of bubble generation capability.

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If strong water circulation is applied to transfer detergent, then washing efficiency increases, but laundry surfaces and fibers may be damaged

Engineering Contradiction:
Improvedetergent transfer efficiencyVSAvoidlaundry surface damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

Bubbles serve as a gentle intermediary that facilitates detergent water infiltration without the harsh mechanical action of strong water circulation. The bubbles rise through the laundry, allowing detergent water to penetrate surfaces and fibers softly, thereby maintaining washing efficiency while preventing damage to laundry surfaces and fibers.

Inventive Principle:
Principle #24Intermediary (Mediator)
