Solution Overview

Problem

Automated sample analyzers often experience idle time due to insufficient consumable items, as users may forget to replenish or incorrectly refill containers, leading to interruptions in scheduled analytical tests.

Innovation Solution

The method involves a consumable repository with multiple storage areas, where the analyzer reserves and switches between areas based on test orders, indicating when a storage area needs replenishment, allowing for timely replenishment and reducing user interaction and errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If consumable items are manually replenished by users, then the analyzer can operate with basic functionality, but idle time increases and operational reliability deteriorates due to user errors and forgetfulness

Engineering Contradiction:
Improveoperational reliabilityVSAvoidanalyzer idle time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by reserving consumable items in storage areas before they are actually needed for analysis. The controller monitors consumable usage and proactively manages replenishment timing, switching between multiple storage areas to ensure continuity of operation without idle time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The analyzer performs self-service by automatically monitoring its own consumable inventory levels and managing replenishment operations. The controller detects when consumable items are running low and initiates replenishment sequences without requiring constant user intervention, thereby improving reliability and reducing idle time.

Inventive Principle:
Principle #25Self-service

2Reliability

If multiple storage areas are used for consumable items, then consumable availability improves, but device complexity increases

Engineering Contradiction:
Improveconsumable availabilityVSAvoidrepository structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The consumable repository is segmented into multiple independent storage areas (first storage area, second storage area, etc.). Each storage area can be independently managed, monitored, and replenished. This segmentation allows the system to maintain high consumable availability by switching between areas while keeping the overall system manageable through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller acts as an intermediary that manages the complexity of multiple storage areas. It automatically tracks consumable levels in each area, determines when to switch between areas, and coordinates replenishment operations, thereby hiding the complexity from the user while ensuring reliable consumable availability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If automated reservation and switching between storage areas is implemented, then analyzer productivity improves, but device complexity and initial cost increase

Engineering Contradiction:
Improveanalyzer productivityVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The controller implements feedback mechanisms by continuously monitoring consumable item levels in storage areas and automatically adjusting reservation and switching operations. This feedback loop ensures optimal productivity by preventing idle time due to consumable shortages while managing system complexity through intelligent automation rather than purely mechanical systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary reservation of consumable items in appropriate storage areas before analysis runs begin. This preliminary action ensures that consumables are ready and available, maximizing analyzer productivity from the start of each analysis sequence without requiring complex real-time decision-making during operation.

Inventive Principle:
Principle #10Preliminary action

AI summary

One aspect of the present disclosure relates to a method for supplying consumable items to an automated sample analyzer, the automated analyzer including a consumable repository including two or more storage areas, each area being configured to store a plurality of consumable items, wherein the method includes receiving one or more orders for analytical tests to be carried out by the analyzer, reserving consumable items corresponding to one or more sets of consumable items required for the analytical tests in a first area, switching to a second area for reserving consumable items in response to determining that a predetermined consumable item in the first area has been reserved, supplying the reserved consumable items for use in the one or more analytical tests and indicating that the first area can be replenished in response to determining that a particular consumable item of the first storage area has been used.
