Solution Overview

Problem

Existing biological sample analysis instruments require manual handling of reagent containers, which is time-consuming and risks contamination.

Innovation Solution

A binding-member-attached reagent container with a detachable strip-shaped binding member that integrates multiple reagent containers, allowing them to be handled as a unit and preventing contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple reagent containers are manually handled one by one, then each container can be individually operated, but the operation time increases and contamination risk increases

Engineering Contradiction:
Improvehandling efficiencyVSAvoidoperation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

Multiple reagent containers are merged into a single integrated unit by attaching a binding member that surrounds and secures all containers together. This allows the entire set of containers to be handled as one unit, eliminating the need to manually pick up and operate each container individually, thereby reducing operation time and contamination risk while maintaining individual container accessibility.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If multiple reagent containers are manually handled one by one, then each container can be individually operated, but the contamination risk increases

Engineering Contradiction:
Improvehandling efficiencyVSAvoidcontamination risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The binding member serves as an intermediary element between the user's hands and the reagent containers. Instead of directly touching the containers, the user handles the binding member, which in turn secures the containers together. This intermediary structure prevents direct contact with the containers, reducing contamination risk while still allowing individual containers to be accessed and operated when needed.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If a binding member is used to secure multiple reagent containers, then handling efficiency improves, but the device complexity increases

Engineering Contradiction:
Improvehandling efficiencyVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The binding member is designed as a flexible strip or band that can be easily wrapped around and secured to multiple reagent containers. This flexible film-like structure provides effective binding without requiring complex mechanical assemblies, motors, or actuators. The simplicity of the flexible binding member maintains low device complexity while achieving high handling efficiency through the integrated container arrangement.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

A binding-member-attached reagent container includes a plurality of reagent containers provided in series and in contact with each other, and a detachable strip-shaped binding member integrally surrounding the plurality of reagent containers. An inspection device is an inspection device allowing the binding-member-attached reagent container to be loaded therein, and includes a storage rack having, at an upper portion thereof, a loading port through which the binding-member-attached reagent container is loaded, and configured to allow the binding-member-attached reagent container to be loaded such that the plurality of reagent containers are stacked in a vertical direction. The storage rack is provided with an opening portion such that the binding member of the loaded binding-member-attached reagent container is detachable from an outside.
