Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional mixing techniques (stirring homogenizer, bead shot homogenizer, high-speed homogenizer) are used to achieve efficient mixing, pulverization, emulsification, and solubilization, then the mixing effect is improved, but the device size increases and becomes complicated

Engineering Contradiction:

Improvemixing efficiencyVSAvoiddevice size

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical mixing systems (impellers, bead shot mechanisms, high-pressure pumps) with a simple flow path structure containing protrusions. The mixing action is achieved through fluid dynamic effects (turbulence, cavitation, shear forces) generated by the protrusions, eliminating the need for complex mechanical components while maintaining high mixing efficiency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts and isolates the essential mixing function from complex mechanical systems. By using only a flow path with protrusions, it removes unnecessary mechanical components (motors, impellers, control systems) while retaining the core mixing capability through fluid-structure interaction

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If conventional mixing techniques are used to achieve comprehensive mixing capabilities, then the mixing effect is improved, but the device becomes complicated and introduction cost becomes expensive

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The mixing section with protrusions can be designed as a simple, replaceable component that is easy to manufacture and install. The design allows for cost-effective production and potential replacement without requiring complex mechanical systems, reducing both initial investment and maintenance costs

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Productivity

If conventional mixing techniques are used to achieve versatile mixing capabilities, then the mixing effect is improved, but versatility as a mixing device is lowered due to material selection requirements

Engineering Contradiction:

Improvemixing capabilityVSAvoidversatility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The flow path with protrusions serves as a universal mixing structure that can handle various materials (liquids, gases, solids, powders) without requiring specific material selection or device modification. The protrusions generate universal fluid dynamic effects (turbulence, cavitation, shear) that work effectively across different material types, enhancing versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A mixing device includes a mixing section that mixes a first liquid-phase fluid with one kind or two or more kinds among a solid, a gas, and a second liquid-phase fluid different from the first liquid-phase fluid, in which the mixing section includes a supply hole for a fluid, a discharge hole for the fluid, a flow path that makes the supply hole and the discharge hole communicate with each other, and pins that protrude from the mixing section such that a fluid that includes materials to be mixed is supplied from the supply hole to the flow path, mixed by passing through the flow path with contact with the pins, and discharged from the discharge hole.
