Solution Overview

Problem

Conventional histamine measurement methods require invasive sampling by mincing edible parts, limiting the number of specimens that can be examined and making full inspection impossible, which is labor-intensive and time-consuming.

Innovation Solution

A non-invasive sampling method for histamine measurement that allows for determining the presence or absence of histamine in a specimen without destroying it, using techniques such as swabbing from specific sites like the mouth, gill slit, or surface of fish or chicken meat, followed by histamine measurement using histamine dehydrogenase or immunochromatography.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional histamine measurement methods are used requiring mincing of edible parts, then histamine measurement can be performed, but the specimen is destroyed and cannot be sold as a commercial product

Engineering Contradiction:
Improvehistamine measurement capabilityVSAvoidspecimen destruction
Core Design Contradiction:
Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The invention segments the sampling process by taking only a small portion of the specimen (e.g., from gill slit, mouth, or surface) rather than requiring mincing of the entire edible part. This allows histamine measurement while preserving the majority of the specimen for commercial use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts only the necessary sample material from specific locations (gill slit, mouth, surface) of the specimen rather than destroying the entire specimen through mincing. This extraction approach enables measurement while maintaining the specimen's commercial value.

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If conventional histamine measurement methods requiring mincing are used, then histamine can be measured, but labor intensity increases and examination time increases

Engineering Contradiction:
Improvehistamine measurement capabilityVSAvoidexamination efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The invention performs preliminary sampling at specific locations (gill slit, mouth, surface) before the measurement process. This preliminary action simplifies subsequent measurement steps and reduces overall labor intensity and examination time compared to conventional mincing methods.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By extracting sample material from easily accessible locations such as gill slits, mouth, or surface, the invention eliminates the labor-intensive mincing process. This extraction approach significantly improves productivity while maintaining measurement accuracy.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If conventional histamine measurement methods are used, then histamine content can be determined, but full inspection of all specimens becomes impossible

Engineering Contradiction:
Improvehistamine measurement capabilityVSAvoidinspection coverage
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The invention segments the inspection process into rapid, non-invasive sampling at key locations (gill slit, mouth, surface) that can be performed on multiple specimens efficiently. This segmentation enables full inspection of all specimens without the time-consuming mincing required by conventional methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By extracting samples from easily accessible locations rather than requiring destructive mincing, the invention makes it feasible to inspect all specimens thoroughly. This approach increases adaptability and versatility by allowing comprehensive screening while maintaining specimen integrity for commercial purposes.

Inventive Principle:
Principle #2Taking out (Extraction)
