Solution Overview

Problem

Existing analyzers face challenges in easily replacing sensors to analyze different fluid properties due to the lack of a secure and efficient connection between the analyser body and the sensor part.

Innovation Solution

The analyser comprises a fluid and mechanical connection between the analyser body and the sensor part, featuring perimeter structures that form secure mechanical connections, ensuring no leaks and allowing for easy sensor replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sensors are provided within the analyser body for protection, then sensor protection from external interferences is improved, but sensor replaceability deteriorates

Engineering Contradiction:

Improvesensor protectionVSAvoidsensor replaceability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The analyser is divided into separate functional modules: a protected analyser body and replaceable sensor parts. This segmentation allows sensors to be shielded during operation while enabling easy replacement by detaching and reattaching sensor parts through the connection interface, thus resolving the contradiction between protection and replaceability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sensor part is designed to be inserted into and nested within the analyser body through a connection interface. This nesting arrangement provides physical protection when connected while allowing complete removal and replacement of the sensor part, maintaining both protection and adaptability.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If a secure connection is provided between analyser body and sensor part, then fluid transfer reliability is improved, but connection complexity increases

Engineering Contradiction:

Improvefluid transfer reliabilityVSAvoidconnection structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The connection interface is segmented into distinct functional elements: perimeter structures for mechanical engagement, sealing elements for fluid tightness, and alignment features. This segmentation allows each element to perform its specific function efficiently without requiring a overly complex integrated design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection interface is designed as a universal multi-functional component that simultaneously provides mechanical attachment, fluid sealing, and alignment functions. This multi-functionality reduces the need for multiple separate connection mechanisms, thereby reducing overall complexity while maintaining reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An analyser includes an analyser body, a sensor part and a connection between the sensor part and the analyser body. The connection includes a fluid connection and a mechanical connection including a first connecting surface having a first perimeter structure and a second perimeter structure within the first perimeter structure; and a second connecting surface having a third perimeter structure and a fourth perimeter structure within the third perimeter structure. The first perimeter structure forms a first mechanical connection with the third perimeter structure and the second perimeter structure forms a second mechanical connection with the fourth perimeter structure. The fluid connection is provided within the second mechanical connection.
