Solution Overview

Problem

Current microbubble generators for laundry treatment devices have complex structures, require additional water pumps and multiple valves, leading to high costs and restrictions on water feeding methods, resulting in inefficient detergent use and residual detergent issues.

Innovation Solution

A laundry treating device with a microbubble generator integrated into the detergent box, eliminating the need for multiple valves and optimizing water and detergent usage by directly introducing microbubble water into the washing process, reducing detergent consumption and energy while enhancing cleaning efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a microbubble generator is used in a laundry treating device, then microbubble generating effects are improved, but device complexity increases due to requiring additional water pumps and multiple valves

Engineering Contradiction:
Improvemicrobubble generating effectsVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The microbubble generator is integrated with the detergent box, merging two separate components into one unified structure. This eliminates the need for separate water pumps and multiple valves, reducing device complexity while maintaining microbubble generation functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The detergent box is designed to serve multiple functions: it not only stores and dispenses detergent but also houses the microbubble generator and acts as a water storage chamber. This multi-functionality reduces the overall number of components needed in the laundry treating device.

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

2Ease of operation

If multiple valves are used to control water flow, then water feeding control is improved, but device complexity and cost increase

Engineering Contradiction:
Improvewater feeding controlVSAvoidvalve quantity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system uses natural water pressure differential and gravity to control water flow between the water storage chamber, microbubble generator, and detergent box. The structure itself serves the flow control function that would otherwise require multiple valves, eliminating complex mechanical control components.

Inventive Principle:
Principle #25Self-service

3Productivity

If microbubble water is introduced into the detergent box, then detergent usage efficiency is improved, but water feeding restrictions increase

Engineering Contradiction:
Improvedetergent usage efficiencyVSAvoidwater feeding flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The microbubble generator and water storage chamber are integrated into the detergent box structure, allowing microbubble water to be directly introduced into the detergent mixing chamber. This merging eliminates the need for separate water feeding systems and maintains flexibility while improving detergent efficiency.

Inventive Principle:
Principle #5Merging (Combining)
