Solution Overview

Problem

Existing automatic analyzers require skilled operators to manually set up calibration and control samples, leading to potential errors and inefficiencies, especially when inexperienced personnel or those on night duty need to operate the equipment, and they lack the ability to automatically determine and display the arrangement position of samples when not pre-assigned on the turntable.

Innovation Solution

An automatic analyzer with a sample-container array unit, display unit, input unit, and control unit that automatically determines and displays the arrangement position of samples necessary for measurement based on availability information and specified rules, allowing operators to select items for measurement without pre-setting positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual setting of calibration and control sample positions is required, then measurement accuracy can be maintained through operator control, but operator error and complexity increase for inexperienced personnel

Engineering Contradiction:
Improvemeasurement accuracyVSAvoidoperator complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The automatic analyzer performs self-service by automatically determining and displaying the arrangement positions of calibration and control samples without requiring manual operator input. The control unit automatically identifies available positions on the turntable and presents them to the operator, eliminating the need for operators to manually configure sample positions while maintaining measurement accuracy through systematic automated management.

Inventive Principle:
Principle #25Self-service

2Reliability

If pre-assignment of sample positions is required, then measurement reliability is improved, but setup time and operational efficiency decrease

Engineering Contradiction:
Improvemeasurement reliabilityVSAvoidsetup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically identifying and displaying available positions for calibration and control samples before the measurement process begins. The control unit proactively determines which positions on the turntable are available and presents this information to the operator, so that sample arrangement can be quickly completed without time-consuming manual configuration during operation.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If multiple arrangement positions must be preset for different samples, then measurement precision is maintained, but device complexity and setup burden increase

Engineering Contradiction:
Improveanalysis precisionVSAvoidsetting complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The automatic analyzer performs self-service by automatically determining the arrangement positions of calibration and control samples based on available space on the turntable. The control unit systematically identifies suitable positions and presents them to the operator, eliminating the need for operators to manually configure multiple sample positions while maintaining measurement precision through automated position management.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If automated position determination is implemented, then ease of operation improves for inexperienced personnel, but risk of incorrect settings may increase

Engineering Contradiction:
Improveoperator easeVSAvoidsetting accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system implements feedback by displaying the determined arrangement positions to the operator on the display unit. This allows the operator to verify the automatically determined positions before proceeding with sample arrangement, providing a check mechanism that prevents incorrect settings while maintaining ease of operation for inexperienced personnel.

Inventive Principle:
Principle #23Feedback
