Solution Overview

Problem

Existing methods for producing marbled vegan meat substitutes are discontinuous, complex, costly, and limited in flexibility, with challenges in adjusting the distribution and volume ratios of secondary masses, and lack the ability to create realistic marbling structures efficiently.

Innovation Solution

A device with multiple nozzles and mixers that allow for continuous production of marbled food products by injecting additional mass flows into a base mass flow, enabling adjustable nozzle positions, depths, and flow rates to create lifelike marbling patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual work steps are used to incorporate secondary mass into base mass, then marbling structure can be created, but production is discontinuous and hourly output is very low

Engineering Contradiction:
Improvemarbling structure qualityVSAvoidhourly output
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical work with a mechanical injection system consisting of nozzles that inject additional mass flows into the base mass flow. This substitution enables continuous production while maintaining marbling structure quality, resolving the contradiction between manufacturing precision and productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If manual adjustment methods are used for distribution and volume ratios, then some control is achieved, but the process is complicated and time-consuming

Engineering Contradiction:
Improvedistribution controlVSAvoidprocess complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent uses adjustable nozzles with variable positions, depths, and flow rates to control the distribution and volume ratios of additional mass in the base mass. By changing physical parameters (nozzle position, depth, flow rate) rather than complex manual adjustments, the system achieves precise control with simpler operation.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If coextrusion dies are used for simultaneous extrusion of inner and outer mass, then production can be continuous, but marbling structure cannot be created

Engineering Contradiction:
Improvecontinuous productionVSAvoidmarbling structure
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent segments the additional mass into multiple separate flows injected through multiple nozzles at different positions and depths into the base mass flow. This segmentation allows continuous production while creating the complex marbling structure that single-channel coextrusion cannot achieve.

Inventive Principle:
Principle #1Segmentation

4Productivity

If existing manufacturing processes are used, then production can proceed, but the range of usable masses is very limited

Engineering Contradiction:
Improveproduction capabilityVSAvoidrange of usable masses
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal injection system that can handle various types of pasty masses (base mass and additional mass) with different properties. The adjustable nozzles and continuous flow system can accommodate different mass combinations, enabling the production of diverse marbled food products beyond what existing processes allow.

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