Solution Overview

Problem

Current sample test automation systems face inefficiencies in processing individual samples using a sample holder that requires manual operation, leading to increased workload, risk of sample mix-up, and infection risk due to manual handling, as well as reduced working efficiency due to distant carrying-out and re-carry-in locations for error samples.

Innovation Solution

A sample test automation system utilizing a sample tray with an attached identifier, where an identifier reading apparatus and operation control unit manage sample information and processing based on the identifier, allowing for customizable conveyance destinations and error handling, reducing the need for manual screen reference and optimizing operator routes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a sample holder is used to process individual samples, then each sample can be handled individually, but manual operation is required which increases workload and risk of sample mix-up

Engineering Contradiction:
ImproveIndividual sample processing capabilityVSAvoidManual operation requirement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system enables self-service operation through automatic identifier reading and information management. The identifier reading apparatus automatically reads sample information, and the operation control unit automatically manages processing based on the identifier, eliminating the need for manual screen reference and reducing operator workload while maintaining individual sample processing capability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations with an automated information management system. The identifier reading apparatus and operation control unit substitute for manual handling and screen reference, automating the decision-making process for sample processing while preserving the flexibility to handle individual samples differently

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If error samples are carried out to distant locations, then error handling can be separated from normal processing, but operator routes become inefficient and working efficiency is reduced

Engineering Contradiction:
ImproveError handling separationVSAvoidOperator working efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically determines conveyance destinations based on the type of error that occurred. The operation control unit selects from multiple possible destinations, allowing flexible routing that optimizes operator routes while maintaining proper error handling separation. This dynamic approach enables efficient recovery operations by placing them at optimized locations rather than fixed distant locations

Inventive Principle:
Principle #15Dynamics

3Loss of information

If manual screen reference is required for error handling, then operators can access detailed information, but operator workload increases and working efficiency decreases

Engineering Contradiction:
ImproveInformation accessibilityVSAvoidOperator working efficiency
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The system provides self-service information delivery by automatically presenting relevant error information to the operator without requiring manual screen reference. The operation control unit retrieves and displays necessary information based on the identifier reading, enabling operators to handle errors efficiently while maintaining access to all required information

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The operation control unit acts as an intermediary between the identifier reading apparatus and the operator. It automatically processes the identifier information, determines the appropriate error handling procedure, and presents relevant information to the operator, eliminating the need for manual screen reference while ensuring complete information accessibility

Inventive Principle:
Principle #24Intermediary (Mediator)
