Solution Overview

Problem

Automated laboratory systems face inefficiencies in managing urgent samples due to the presence of non-urgent samples occupying space and causing longer queues, which hinders the timely processing of urgent samples despite software and hardware features that attempt to provide priority.

Innovation Solution

A process that identifies urgent and non-urgent test tubes using recognition devices, physically removes non-urgent tubes from the system until urgent samples are processed, and temporarily stores them on waiting benches, allowing urgent samples to be prioritized by moving them directly to processing modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If FIFO rule is applied in automation installation, then processing order is simple and systematic, but urgent samples cannot be prioritized over non-urgent samples

Engineering Contradiction:
Improveprocessing order managementVSAvoidprocessing time of urgent samples
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system dynamically adjusts processing priorities based on sample urgency classification. The conveyor system can switch between FIFO mode and priority-based mode, where urgent samples are identified through recognition devices and routed to expedited processing lanes, while non-urgent samples continue through standard FIFO processing. This dynamic adaptation resolves the contradiction by maintaining simple FIFO operation for routine samples while enabling urgent sample prioritization when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The processing system is segmented into multiple independent lanes: urgent sample lanes and non-urgent sample lanes. Once samples are classified by urgency, they are routed to appropriate segments. This segmentation allows urgent samples to be processed in dedicated lanes without being blocked by non-urgent samples in other lanes, thus maintaining simple operation within each segment while achieving priority processing for urgent cases.

Inventive Principle:
Principle #1Segmentation

2Loss of time

If priority features are provided at software and hardware level, then urgent samples can be assigned priority, but non-urgent samples occupy physical spaces and generate longer queues

Engineering Contradiction:
Improveprocessing time of urgent samplesVSAvoidoverall system throughput
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

Non-urgent samples are extracted from the main processing flow and placed in temporary holding areas or separate queues. This extraction removes the blocking effect that non-urgent samples have on urgent sample processing. The system maintains separate physical or virtual storage spaces where non-urgent samples wait without occupying critical processing resources needed for urgent samples, thus reducing queue lengths for urgent cases while maintaining overall system productivity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Temporary holding areas or buffer zones act as intermediaries between sample intake and processing modules. Non-urgent samples are placed in these intermediary spaces, allowing the main processing flow to continue uninterrupted. This intermediary storage decouples the processing of urgent and non-urgent samples, enabling urgent samples to access processing modules immediately while non-urgent samples wait in the intermediary zone, thus resolving the conflict between priority processing and overall productivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If non-urgent samples are removed from the installation, then urgent samples can be processed faster, but physical spaces must be provided for temporary storage

Engineering Contradiction:
Improveprocessing time of urgent samplesVSAvoidspace for temporary storage
Core Design Contradiction:
Loss of timeVSArea of stationary object

Solution Approach 1:

The system utilizes vertical space or multi-level storage structures for temporary holding of non-urgent samples rather than expanding horizontal footprint. By moving storage to another dimension (vertical stacking, multi-tier racks), the system provides adequate temporary storage capacity without significantly increasing the overall floor area occupied by the automation installation, thus enabling urgent sample prioritization while minimizing space requirements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

Temporary storage areas are nested within existing structural elements of the automation installation. Holding zones for non-urgent samples are integrated into unused spaces within the conveyor system, processing module housings, or along the sides of existing equipment. This nesting approach provides necessary temporary storage capacity while utilizing already-available space, thus minimizing the additional area required for storing non-urgent samples during priority processing.

Inventive Principle:
Principle #7Nested doll (Nesting)
