Solution Overview

Problem

Automated analytical instruments face inefficiencies in transporting sample racks of different formats between work cells, requiring complex and time-consuming reformatting operations.

Innovation Solution

A junction and transport device with multiple main transport lines, a turntable, and bypass lines that allow for efficient transportation of sample racks of varying sizes by rotating rotatable transport lines and using controllable switches to guide racks between lines, enabling flexible and efficient movement of both single and multi-vessel racks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex reformatting operations are performed to accommodate different rack formats, then different work cells can use different rack formats, but the process becomes time-consuming and expensive

Engineering Contradiction:
Improverack format compatibilityVSAvoidreformatting time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The transport system is segmented into multiple dedicated transport lines, each optimized for specific rack formats. This allows different rack types to be transported simultaneously on different lines without requiring reformatting operations, thereby maintaining adaptability while eliminating time loss.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The junction device is designed with multi-functional capabilities to handle multiple rack formats through a single unified structure. It provides universal access to different work cells regardless of rack type, eliminating the need for complex reformatting while maintaining versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If dedicated transporting devices are used for different rack formats, then transport efficiency improves, but device complexity increases

Engineering Contradiction:
Improvetransport efficiencyVSAvoidtransport system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple dedicated transport lines are merged into a single junction device that provides unified control and coordination. This combining approach maintains the productivity benefits of dedicated lines while reducing overall system complexity through centralized management.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The junction acts as an intermediary device that coordinates between different dedicated transport lines and work cells. It simplifies the overall system architecture by providing a single point of control rather than requiring complex direct connections between each transport line and work cell.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If bypass lines are added to enable selective rack transport, then flexibility in routing different rack types improves, but the number of transport components increases

Engineering Contradiction:
Improverouting flexibilityVSAvoidtransport line complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transport system incorporates dynamic switching capabilities at the junction that allow flexible routing of different rack types through bypass lines or main lines based on real-time requirements. This dynamic adaptability provides routing flexibility without requiring permanent, complex infrastructure for every possible configuration.

Inventive Principle:
Principle #15Dynamics
