Solution Overview

Problem

The shipping and handling of liquid reagents in laboratory settings often result in degradation and spillage due to the labor-intensive preparation of reagent solutions, necessitating an improved reagent container and instrument interface to reduce preparation times and prevent fluid leakage.

Innovation Solution

A fluidic interconnect system featuring a first interface with a liquid port, a gas port, and a cradle, and a second interface with a liquid port, a gas port, and a swing bar that engages the cradle, allowing the container to swing into place and form a leak-tight seal, enabling efficient connection and fluid transfer between the container and instrument.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If pre-made reagent solutions are shipped and handled in liquid form, then preparation time is reduced, but degradation and spillage occur during shipping and handling

Engineering Contradiction:
Improvepreparation timeVSAvoidreagent stability
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The reagent is changed from liquid to frozen state, fundamentally altering its physical parameter to prevent degradation and spillage during shipping while maintaining the benefit of pre-preparation

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The reagent is prepared in advance and frozen in the container before shipping, eliminating the need for laboratory preparation while ensuring stability during transport

Inventive Principle:
Principle #10Preliminary action

2Productivity

If a removable container interface is used to reduce preparation time, then connection speed is improved, but the risk of spillage and degradation increases

Engineering Contradiction:
Improveconnection speedVSAvoidfluid containment
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

A cradle structure acts as an intermediary mechanism between the container and instrument, guiding the swing bar into proper alignment and ensuring secure engagement that prevents spillage while maintaining quick connection

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The swing bar mechanism provides dynamic, self-aligning connection that swings into place under gravity or spring force, enabling rapid connection while the cradle ensures proper positioning to prevent leakage

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the cradle is positioned further from the panel than the liquid port, then the swing bar engagement is facilitated, but the structural complexity increases

Engineering Contradiction:
Improveswing bar engagementVSAvoidinterface structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cradle is positioned to create a natural pivot point that allows the swing bar to engage smoothly using gravity or minimal force, equalizing the engagement process and reducing the need for complex alignment mechanisms

Inventive Principle:
Principle #12Equipotentiality
