Solution Overview

Problem

The existing methods for manufacturing surimi sticks fail to replicate the texture and appearance of real crab claw meat, limiting the variety and diversity of products offered in the market.

Innovation Solution

A method involving the creation of ultra-fiber rods by winding at least three strips of edible dough around each other, with the outer strip forming an envelope, and subsequent cutting to create sticks that mimic the appearance and texture of crab claw meat, using a process that includes scarification, winding, and partial flattening to achieve the desired fiber structure and appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional spreading and rolling methods are used to manufacture surimi sticks, then the manufacturing process is simple, but the texture and appearance cannot replicate real crab claw meat

Engineering Contradiction:
Improvetexture and appearance replicationVSAvoidwinding process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The edible dough is divided into multiple strips (at least three) with different treatments (scarified vs. unscarified). These segmented strips are then wound around each other to create the ultra-fiber structure, allowing each strip to contribute differently to the final texture and appearance

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The scarified strips are wound around each other in a nested configuration, with each strip forming a layer around the previous ones. The unscarified strip forms an outer envelope around the nested scarified strips, creating a multi-layered structure that replicates crab meat fibers

Inventive Principle:
Principle #7Nested doll (Nesting)

2Manufacturing precision

If scarification is applied to all strips, then fiber texture is enhanced, but structural integrity and binding are compromised

Engineering Contradiction:
Improvefiber textureVSAvoidstructural integrity
Core Design Contradiction:
Manufacturing precisionVSStrength

Solution Approach 1:

Different quality treatments are applied to different strips: at least two strips are scarified to create ultra-fiber texture, while at least one strip remains unscarified to provide structural integrity and binding. This local differentiation of properties allows both texture and strength requirements to be met simultaneously

Inventive Principle:
Principle #3Local quality

3Strength

If the envelope strip is made thick, then structural strength is improved, but the natural appearance and ultra-fiber texture are compromised

Engineering Contradiction:
Improveenvelope strengthVSAvoidnatural appearance
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The unscarified envelope strip is applied at a thickness that is sufficient to provide structural strength and binding, but not excessive. The strip thickness is carefully controlled to maintain the natural appearance and ultra-fiber texture visibility, achieving the right balance between strength and aesthetics

Inventive Principle:
Principle #16Partial or excessive action
