Solution Overview

Problem

Automatic analyzers face challenges in maintaining a compact size while replacing reagent containers due to interference between the reagent transport mechanism and the reagent probe, which can lead to equipment size issues and operational interruptions.

Innovation Solution

The reagent transport mechanism is designed to move at the same height as the reagent probe, with sensors detecting the position to prevent interference and minimize non-resettable regions, allowing for continuous operation without stopping the analysis process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the reagent transport mechanism is configured to move at the same height as the reagent probe, then the equipment size is kept small, but the mechanism and the probe may interfere with one another

Engineering Contradiction:
Improveequipment sizeVSAvoidinterference between mechanism and probe
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The reagent transport mechanism is designed with movable components that can dynamically adjust their position. The mechanism includes a transport arm that can move between a horizontal transporting position and a vertical retracted position, allowing it to adapt its configuration based on operational needs and avoid interference with the reagent probe while maintaining compact equipment size.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent resolves the interference issue by introducing vertical movement dimension to the reagent transport mechanism. Instead of moving only horizontally at the same height as the probe, the mechanism can lift vertically to pass above or below the probe's operational zone, effectively using three-dimensional space to eliminate collisions while maintaining a compact horizontal footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the reagent transport mechanism and reagent probe are configured not to interfere with one another, then operational reliability is improved, but the equipment size becomes inordinately large

Engineering Contradiction:
Improveoperational reliabilityVSAvoidequipment size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The reagent transport mechanism incorporates dynamic positioning capabilities with movable arms and adjustable components that can change their spatial configuration during operation. This allows the system to maintain a compact form factor while dynamically avoiding interference zones with the reagent probe through coordinated movement in multiple dimensions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs a nested configuration where the reagent transport mechanism components are arranged to fit within or alongside the reagent probe structure. The transport arm can be positioned to nest near the probe when not in use, and the mechanism utilizes the vertical space efficiently by allowing the probe to extend upward while the transport mechanism operates in the surrounding space without requiring additional horizontal footprint.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If reagent containers are replaced more frequently due to higher consumption rates, then the analyzer can handle more specimens and measurements, but the workload on operators increases

Engineering Contradiction:
Improvespecimen processing capacityVSAvoidoperator workload
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements an automated reagent replacement system where the reagent transport mechanism automatically transports empty reagent containers from the reagent storage unit to the analysis unit and delivers full reagent containers back to the storage unit. This self-service capability eliminates manual intervention for reagent replacement, allowing the system to handle higher specimen volumes without increasing operator workload.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The automated reagent replacement system enables continuous operation of the analyzer by ensuring reagents are continuously replenished without interrupting specimen processing. The transport mechanism operates in coordination with the analysis unit to maintain uninterrupted reagent supply, allowing the system to sustain high productivity levels continuously rather than requiring periodic manual reagent changes that would create operational interruptions.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

An automatic analyzer is provided which applies a position detection mechanism to at least either a reagent probe or a reagent container transfer mechanism, thereby performing control on or inhibiting a reset operation (initialization) of either the reagent probe or the reagent container transfer mechanism to prevent the transfer thereof. This allows a reagent transport mechanism attached to the automatic analyzer automatically replacing reagent containers to be configured to move at the same height as those of various units including the reagent probe. The automatic analyzer is thus made small in size and allowed to operate without problems.
