Solution Overview

Problem

Conventional surimi sticks lack variety in taste and texture, and no surimi-based product imitating a scallop nut has been marketed, limiting consumer options.

Innovation Solution

A process for manufacturing surimi-based food products in the form of pectinid nuts, such as scallop nuts, by extruding a strip of surimi with a width greater than 160 mm, scarifying, rolling, and cutting to create nuts with a diameter and texture similar to natural scallops, and optionally freezing or crusting for extended storage and flavor retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional surimi sticks are manufactured using narrow strips (1-2 mm thick), then the manufacturing process is simple and production efficiency is high, but the product lacks variety in taste and texture

Engineering Contradiction:
Improveproduct varietyVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The manufacturing process is segmented into distinct stages: extrusion of wide strip, scarification treatment, rolling formation, and cutting. This segmentation allows each step to be optimized independently, enabling complex product forms from simple base materials while maintaining manufacturing efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from conventional narrow strips to wide strips (greater than 160 mm width), adding dimensional variation to the base material. This dimensional change enables the creation of scallop nut shapes and textures that cannot be achieved with traditional narrow strip configurations

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If scarification depth is increased to achieve fibrous texture similar to natural scallops, then product authenticity is improved, but risk of strip disintegration increases

Engineering Contradiction:
Improvetexture accuracyVSAvoidstrip integrity
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The scarification process parameters are precisely controlled, with depth set between 0.2-0.5 mm and spacing between 1-3 mm. These parameter optimizations create the desired fibrous texture while maintaining sufficient structural integrity of the surimi strip throughout processing

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The surimi strip undergoes preliminary cooling and stabilization before scarification, ensuring the material is in optimal condition to withstand the mechanical treatment. This preliminary preparation prevents disintegration during the scarification process while still achieving the desired fibrous texture

Inventive Principle:
Principle #10Preliminary action

3Duration of action of stationary object

If surimi nuts are subjected to freezing or crusting treatment, then storage duration is extended and flavor is retained, but additional processing steps and time are required

Engineering Contradiction:
Improvestorage durationVSAvoidproduction speed
Core Design Contradiction:
Duration of action of stationary objectVSProductivity

Solution Approach 1:

Freezing or crusting treatment is applied as a preliminary step before packaging and pasteurization. This sequencing allows the product to be prepared in advance with extended shelf life, enabling more efficient production scheduling and reduced rush processing later

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The freezing process utilizes phase transition of water in the surimi matrix to preserve the product. This phase change locks in flavor and texture characteristics while extending storage life, with the frozen state serving as a stable intermediate before final pasteurization

Inventive Principle:
Principle #36Phase transitions
