Solution Overview

Problem

Existing automatic analyzers face challenges in efficiently managing the dispensing order of samples, particularly when emergency samples need priority analysis, leading to increased analysis times and difficulties in responding to various operational environments.

Innovation Solution

An automatic analyzer and control method that allows flexible sample disk configuration without predefined installation positions, enabling dynamic priority setting and dispensing orders based on emergency, quality control, and general samples, with options to interrupt standard solutions or quality control samples to prioritize emergency samples.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed dispensing priority order is set (standard solution → emergency sample → quality control sample → general sample), then the system structure is simple and easy to operate, but the analysis time increases when emergency samples need to be prioritized

Engineering Contradiction:
Improveease of operationVSAvoidanalysis time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent implements dynamic priority assignment where the control unit can change the dispensing priority of samples based on real-time operational needs. When an emergency sample is detected, the system dynamically adjusts its priority to be higher than standard solutions and quality control samples, allowing flexible response to different operational scenarios while maintaining a structured control framework

Inventive Principle:
Principle #15Dynamics

2Loss of time

If emergency samples are always given highest priority, then emergency sample analysis is rapid, but standard solution measurement may be delayed causing invalid calibration curves

Engineering Contradiction:
Improveemergency sample analysis timeVSAvoidcalibration curve validity
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system performs preliminary detection of emergency samples and proactively manages the dispensing sequence. When an emergency sample is detected, the control unit preemptively adjusts the priority before dispensing begins, ensuring rapid response while the system simultaneously checks whether standard solutions have been recently measured to maintain calibration validity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control unit changes the priority parameter of samples dynamically based on sample type and operational context. The priority is not fixed but can be adjusted in real-time, allowing the system to optimize between emergency response speed and calibration maintenance by changing the dispensing priority parameter according to current needs

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If predefined installation positions are used on the sample disk, then the device structure is simple, but the system cannot adapt to various operational environments and sample types

Engineering Contradiction:
Improvedevice structureVSAvoidadaptability to operational environments
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system uses a barcode reader to dynamically identify sample types and automatically determines the optimal dispensing priority based on the detected sample information. This dynamic identification and priority assignment system allows the analyzer to adapt to various operational environments and sample types without requiring complex predefined position configurations or manual setup

Inventive Principle:
Principle #15Dynamics
