Solution Overview

Problem

Frozen minced fish meat tends to agglutinate during storage, leading to insufficient individualization when opened for cooking, which affects consumer convenience.

Innovation Solution

Packaging frozen minced fish meat with a gas containing at least 22% oxygen by volume, which inhibits hydrogen bond participation in agglutination, along with inert gases if necessary, and using specific fish types and packaging materials to maintain minimal agglutination levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If frozen minced fish meat is stored in package containers, then it maintains convenience and ease of use, but the particles are likely to be agglutinated to each other

Engineering Contradiction:
Improveconvenience for consumersVSAvoidagglutination of frozen minced fish meat
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent changes the chemical composition parameters of the packaging atmosphere by controlling the oxygen concentration to 21-30% by volume. This parameter change prevents agglutination by inhibiting hydrogen bond formation between frozen minced fish meat particles, while maintaining the convenience of packaged storage for consumers.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If the oxygen content in packaging gas is increased to prevent agglutination, then individualization is improved, but oxidation of fish meat may occur

Engineering Contradiction:
Improveindividualization of frozen minced fish meatVSAvoidoxidation of fish meat
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the oxygen concentration parameter to a specific range of 21-30% by volume. This controlled parameter change provides sufficient oxygen to prevent agglutination through hydrogen bond inhibition, while limiting oxidation damage by preventing excessive oxygen accumulation. The balanced parameter setting achieves both individualization and quality preservation.
