Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If rotating mixing blades are used to mix liquids, then the liquid in the vicinity of the blades can be stirred, but particles in the liquid cannot be evenly distributed and cleaning becomes difficult

Engineering Contradiction:

Improvemixing effectivenessVSAvoidcleaning difficulty

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent removes the traditional rotating mixing blades from the system and replaces them with an injection-based mixing mechanism. The injection module penetrates the container wall and injects liquid directly into the container, eliminating the need for internal mixing blades that are difficult to clean. This extraction of the problematic component (blades) while maintaining the mixing function resolves the contradiction between mixing effectiveness and cleaning ease.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical stirring action of rotating blades with a fluid injection system. Instead of using mechanical contact between blades and liquid, the system uses injected liquid streams to achieve mixing through fluid dynamics. This substitution eliminates the mechanical components that create cleaning difficulties while maintaining effective mixing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If mixing blades are used to distribute particles evenly, then some mixing action is achieved, but particles may clog up the blades making cleaning difficult

Engineering Contradiction:

Improveparticle distribution uniformityVSAvoidcleaning ease

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent extracts the mixing function from the container interior by placing the injection module outside the container. The injection module penetrates the container wall and introduces mixing action from the exterior, eliminating internal surfaces where particles can accumulate and clog. This external injection approach maintains particle distribution capability while eliminating clogging issues.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of placing mixing elements inside the container (traditional approach), the patent inverts the arrangement by placing the injection module outside the container and penetrating through the wall. This inversion allows the mixing action to be applied from the exterior, preventing particle accumulation on mixing surfaces and facilitating easier cleaning.

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If the annular protrusion is close to the inner wall to reduce gap, then mixing intensity increases, but the risk of clogging increases

Engineering Contradiction:

Improvemixing intensityVSAvoidclogging risk

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent makes the gap between the annular protrusion and the inner wall adjustable rather than fixed. The adjusting module allows dynamic modification of the gap size based on operational requirements. This dynamics enables the system to optimize between mixing intensity (smaller gap) and clogging prevention (larger gap) by adjusting the gap according to the specific mixing task and fluid characteristics.

Inventive Principle:

Principle #15Dynamics

AI summary

An injection mixer is provided, which includes an injection module, a valve seat module, and an adjusting module. The injection module may be disposed to penetrate one end of a bucket container. The valve seat module may be disposed at the end of the injection module, and the valve seat module may be disposed with at least one fluid supply channel and at least one outlet channel. The adjusting module may be disposed at the valve seat module to penetrate therethrough. The adjusting module may be movably connected to the injection module. When the adjusting module is driven to move the injection module towards or away from the valve seat module, an annular protrusion may approach or move away from the inner wall of the bucket container, and a size of the predetermined gap may be reduced or increased.
