Modular Fluid Analyzer Interface for Replaceable Sensor Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analyzers face challenges in easily replacing sensors to analyze different properties of fluids, as the sensors are not designed for quick interchangeability.
Innovation Solution
The analyzer features a secure connection between the analyser body and the sensor part, utilizing a combination of mechanical and fluid connections to ensure safe and controlled fluid transfer for measurement, with the connections comprising perimeter structures that form tight mechanical connections.
Engineering Contradictions & Design Principles
Engineering 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
Solution Approach 1:
The analyser is divided into separate functional modules: a protected analyser body and replaceable sensor parts. The sensor part can be detached and replaced while the analyser body remains, allowing both protection during operation and easy replacement when needed.
Solution Approach 2:
The analyser body is designed with a universal connection interface that can accommodate different types of sensor parts. This allows the same analyser body to work with multiple sensor variants for different fluid properties, improving versatility without compromising protection.
2Reliability
If a secure mechanical connection is provided between analyser body and sensor part, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The connection system is segmented into distinct functional elements: perimeter structures for mechanical engagement, fluid connections for fluid transfer, and electrical connections for power and data. This modular segmentation allows each element to be optimized independently while maintaining overall simplicity.
Solution Approach 2:
Multiple connection functions (mechanical securing, fluid transfer, electrical connection) are merged into a single integrated connection interface. This allows all connections to be established simultaneously through one docking action, reducing operational complexity despite the multi-functional nature of the connection.
