Solution Overview

Problem

Existing agitators face challenges such as inefficient agitation near the inner walls of the tank, complex structures leading to high maintenance and production costs, and the risk of blade deformation and motor burnout due to high load operations.

Innovation Solution

An agitator that circulates materials without using an agitation blade, utilizing pumps to suck and discharge the agitation target through suction and discharge pipes equipped with agitation activators. These activators employ vortices, magnetic fields, static electricity, and galvanic electricity to micronize and activate molecules, improving agitation efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a multi-stage agitator with multiple agitation blades is used to achieve uniform agitation throughout the tank, then agitation uniformity is improved, but device complexity increases, manufacturing cost increases, maintenance difficulty increases, and energy consumption increases

Engineering Contradiction:

Improveagitation uniformityVSAvoidagitator structure complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent removes the complex multi-stage agitation blade system entirely and extracts only the essential function of material circulation. Instead of using multiple blades to achieve uniform agitation, the invention uses a single pump to circulate material from the bottom to the top of the tank, where it disperses naturally to provide uniform agitation without complex structures.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical agitation blade system with a pump-based circulation system. Instead of using mechanical blades to stir the material, the invention uses a pump to create circulation flow, achieving agitation through fluid dynamics rather than direct mechanical contact with blades.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Power

If a high load is consistently applied to the agitation blade by forcing rotation through the agitation target, then agitation power is improved, but reliability decreases due to blade deformation and motor burnout risk

Engineering Contradiction:

Improveagitation powerVSAvoidblade and motor reliability

Core Design Contradiction:

PowerVSReliability

Solution Approach 1:

The patent replaces the high-load mechanical blade rotation system with a pump-based circulation system. The pump draws material from the bottom and discharges it at the top, creating circulation without the need for high-torque blade rotation. This substitution eliminates the risk of blade deformation and motor burnout while maintaining effective agitation through circulation-induced mixing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If an agitation blade is used to stir material in the tank, then agitation function is achieved, but ease of operation decreases due to cleaning difficulties and safety risks during maintenance

Engineering Contradiction:

Improvecleaning and maintenance easeVSAvoidagitation effectiveness

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent removes the agitation blade component entirely, extracting only the essential circulation function. Without blades to clean or maintain, the system eliminates cleaning difficulties and safety risks associated with blade maintenance while preserving agitation effectiveness through pump-driven material circulation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The circulation system creates self-agitation through continuous material movement. The pump draws material from the bottom and discharges it at the top, where natural dispersion and collision provide agitation without requiring additional cleaning or maintenance interventions.

Inventive Principle:

Principle #25Self-service

4Device complexity

If pumps are used to circulate material from bottom to top of the tank, then device complexity is reduced, but agitation uniformity near the inner wall may deteriorate

Engineering Contradiction:

Improveagitator structure simplicityVSAvoidagitation uniformity near inner wall

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by creating different flow patterns in different regions of the tank. The pump creates strong upward flow in the discharge region, while material naturally circulates and mixes in other areas. This localized flow differentiation ensures uniform agitation throughout, including near the inner walls, while maintaining simple overall structure.

Inventive Principle:

Principle #3Local quality
