Solution Overview

Problem

Conventional biological sample processing apparatuses face contamination risks due to residue attachment to inner walls of passages used for supplying reagents, and they often require extra reagent storage to account for feeding losses.

Innovation Solution

The apparatus employs a cartridge-type liquid supplier with a storage and an ejector that directly delivers reagents to an ejection destination, eliminating the need for passages and reducing contamination risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a passage (tube) is used to supply reagent from storage to container, then reagent can be transported, but reagent residue attaches to inner wall causing contamination

Engineering Contradiction:

Improvecontamination riskVSAvoidpassage structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the passage (tube) component from the system by using direct attachment of the reagent bottle to the container. This removes the source of contamination while maintaining reagent supply functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the storage function and the supply function into a single integrated structure where the reagent bottle is directly attached to the container, eliminating the need for separate passage components and reducing contamination risks.

Inventive Principle:

Principle #5Merging (Combining)

2Loss of substance

If passage is used for reagent supply, then reagent can be delivered, but reagent feeding loss occurs due to residue attachment

Engineering Contradiction:

Improvereagent wasteVSAvoidpassage structure

Core Design Contradiction:

Loss of substanceVSDevice complexity

Solution Approach 1:

The passage is removed from the system, eliminating the source of reagent residue attachment and feeding loss while maintaining the reagent supply function through direct bottle-to-container attachment.

Inventive Principle:

Principle #2Taking out (Extraction)

3Quantity of substance

If conventional reagent bottle or bag is attached to storage, then reagent storage is achieved, but contamination risk increases due to passage residue

Engineering Contradiction:

Improvereagent storage capacityVSAvoidcontamination risk

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The reagent bottle is directly attached to the container without intermediate passages, merging storage and supply functions. This integration eliminates passage residue contamination while maintaining full reagent storage capacity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A biological sample processing apparatus includes a holder. The holder detachably holds a liquid supplier. The liquid supplier includes a storage and an ejector. The storage stores a liquid used for processing a biological sample. The ejector pushes the liquid out from inside the storage to eject the liquid directly to an ejection destination.
