Solution Overview

Problem

Inefficient allocation of reagents and tests in clinical analyzers leads to incompatibilities, resulting in reduced throughput and increased turnaround times due to chemical and resource allocation conflicts, causing wasted operational cycles and inaccurate test results.

Innovation Solution

The system optimizes reagent and test allocation by distributing tests across multiple analyzers, using processors to identify incompatible tests and segregate them, and automatically or manually distributing reagents to minimize conflicts, allowing simultaneous operation of tests on different analyzers with compatible resource allocation and chemical profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If tests are scheduled to begin each operation cycle without resource competition, then analyzer throughput is maximized, but test incompatibility and resource conflicts increase

Engineering Contradiction:
Improveanalyzer throughputVSAvoidtest compatibility
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system segments tests into compatibility groups based on reagent and resource requirements. Tests are divided into groups that can be run together without conflicts, allowing the analyzer to process multiple compatible tests simultaneously while maintaining reliability within each group.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The scheduling system dynamically adjusts test allocation based on real-time analyzer state, resource availability, and test compatibility requirements. The system flexibly modifies the operation schedule to optimize throughput while preventing incompatible tests from being scheduled together, adapting to changing conditions rather than using fixed schedules.

Inventive Principle:
Principle #15Dynamics

2Reliability

If tests are delayed to avoid resource competition, then resource allocation conflicts are reduced, but turnaround time increases

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidsample turnaround time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of test compatibility and resource requirements before scheduling. By pre-identifying incompatible test combinations and allocating resources in advance, the system avoids last-minute delays and conflicts, enabling continuous operation without sacrificing reliability.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If additional wash cycles are performed to prevent reagent contamination, then test accuracy is maintained, but operational cycles are wasted and throughput decreases

Engineering Contradiction:
Improvetest accuracyVSAvoidanalyzer throughput
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The system extracts and separates incompatible tests into different scheduling groups, preventing reagent contamination issues before they occur. By removing incompatible test combinations from the schedule entirely, the system eliminates the need for additional wash cycles while maintaining test accuracy through proactive compatibility management.

Inventive Principle:
Principle #2Taking out (Extraction)

4Manufacturing precision

If skipped machine cycles are used to ensure proper test sequencing, then test calibration accuracy is maintained, but overall throughput is reduced

Engineering Contradiction:
Improvetest calibration accuracyVSAvoidanalyzer throughput
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system maintains continuous useful action by scheduling compatible tests back-to-back without idle cycles. By ensuring that every machine cycle performs a valid, calibration-compliant test, the system eliminates skipped cycles while preserving accuracy through careful compatibility-based scheduling.

Inventive Principle:
Principle #20Continuity of useful action
