Solution Overview

Problem

Existing sample extraction methods for micro sampling chips face challenges in efficiently cutting and handling the extraction portion without impairing sample quantitativeness, as the capacity is minute and handling is difficult, leading to potential sample leakage and contamination.

Innovation Solution

A sample extraction tool that cuts the extraction portion of a micro sampling chip using a through hole mechanism, allowing the cut portion to be directly accommodated in a container without touching the analyst's fingers, utilizing centrifugal force for sample transfer and processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the extraction portion is cut from the micro sampling chip manually, then the cutting operation is simple, but the sample may adhere to fingers and quantitativeness is impaired

Engineering Contradiction:
Improvecutting operationVSAvoidsample quantitativeness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A through hole is introduced as an intermediary structure to facilitate the cutting operation. The through hole allows the extraction portion to be inserted and cut without direct finger contact with the sample, serving as a mediator between the cutting tool and the sample-containing extraction portion.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The extraction portion is extracted or separated from the main body of the micro sampling chip through the through hole mechanism, allowing it to be removed and transferred to a container without manual handling of the delicate sample-containing portion.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the extraction portion is handled with fingers, then the handling is flexible, but sample leakage and contamination occur

Engineering Contradiction:
Improvehandling flexibilityVSAvoidsample leakage and contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The through hole acts as an intermediary that enables the cutting and transfer operation without requiring direct finger contact with the extraction portion. This eliminates the harmful effect of sample adhesion to fingers while maintaining operational simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The manual mechanical handling by fingers is replaced with a through hole-based cutting mechanism, substituting the direct mechanical contact system with an indirect cutting system that avoids sample contamination.

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

3Device complexity

If manual handling of the extraction portion is performed, then the operation is simple, but sample adhesion to fingers impairs quantitativeness

Engineering Contradiction:
Improvehandling deviceVSAvoidsample quantitativeness
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The through hole serves as a simple intermediary structure that prevents sample adhesion to fingers during the cutting and transfer operation, maintaining quantitativeness without requiring complex handling devices.

Inventive Principle:
Principle #24Intermediary (Mediator)
