Solution Overview

Problem

Existing automatic analyzers face difficulties in smoothly inserting tubular-shaped reaction vessels into incubators due to increased resistance, which can degrade processing performance.

Innovation Solution

Incorporation of a lubricating member with self-lubricating properties at the inlet port of the incubator's holes to facilitate smooth insertion of reaction vessels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a reaction vessel in a tubular shape is used, then the liquid amount of the sample is reduced, but the resistance at the time of insertion into the hole of the incubator increases

Engineering Contradiction:
Improveliquid amount of sampleVSAvoidinsertion smoothness
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

A lubricating member is introduced as an intermediary component between the reaction vessel and the incubator hole. This lubricating member has a lubricating surface that reduces friction and resistance during insertion, allowing the tubular reaction vessel to be inserted smoothly while maintaining its space-efficient design

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The surface properties of the incubator hole are changed by providing a lubricating surface on the lubricating member. This changes the friction parameter at the interface between the reaction vessel and the hole, reducing resistance from high to low and enabling smooth insertion of the tubular vessel

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If a reaction vessel in a tubular shape is used, then the liquid amount of the sample is reduced, but the processing performance of the automatic analyzer is reduced

Engineering Contradiction:
Improveliquid amount of sampleVSAvoidprocessing performance
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The lubricating member acts as a mediator that eliminates insertion resistance, ensuring that the transfer unit can smoothly insert tubular reaction vessels into the incubator. This maintains the automated processing flow and prevents delays that would reduce processing performance

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The lubricating member has self-lubricating properties, meaning it inherently provides low friction without requiring external lubrication systems or additional components. This self-service characteristic ensures consistent smooth insertion and maintains reliable processing performance

Inventive Principle:
Principle #25Self-service
