Solution Overview

Problem

Existing genetic analysis systems for digital PCR lack optimal compactness and efficiency in sample handling and processing, particularly in the movement of samples between different functional areas.

Innovation Solution

A device with a loading unit that includes an entry area, a loading area, and two movement mechanisms. The first movement mechanism moves a sample holder between the entry area and the loading area, while the second movement mechanism independently moves samples between the loading area, a thermal/pressure area, and a scanning area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single movement mechanism is used to handle both sample holder loading/unloading and sample analysis, then the device complexity is reduced, but the productivity and efficiency of the system deteriorates due to sequential operations

Engineering Contradiction:
Improvemovement mechanism complexityVSAvoidsystem processing efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent divides the sample handling system into two independent movement mechanisms: a first movement mechanism dedicated to loading/unloading sample holders, and a second movement mechanism dedicated to moving samples during analysis. This segmentation allows parallel operation of loading and analysis functions, resolving the contradiction between device simplicity and processing efficiency.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If sample loading and analysis operations are performed sequentially using a single mechanism, then the device structure remains simple, but the loss of time increases due to inability to perform operations simultaneously

Engineering Contradiction:
Improvemechanism structureVSAvoidoperational downtime
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent enables continuous useful action by allowing the first movement mechanism to load sample holders while the second movement mechanism simultaneously moves samples for analysis. This eliminates idle time between operations, as both loading and analysis proceed concurrently without interrupting each other.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If human intervention is required for sample handling operations, then the ease of operation is improved, but the extent of automation deteriorates

Engineering Contradiction:
Improvemanual control capabilityVSAvoidautomatic sample handling
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The patent implements self-service automation where the two movement mechanisms automatically coordinate their operations without requiring manual intervention. The first mechanism autonomously loads sample holders while the second mechanism simultaneously handles sample transfer, creating a self-managing automated system that eliminates the need for operator involvement in routine handling tasks.

Inventive Principle:
Principle #25Self-service
