Solution Overview
Problem
In process measurement technology, existing sensors for liquid and gas analysis often require frequent replacement, leading to the loss of data and program code specific to the measuring point, as well as inefficiencies in replacing electronics with shorter lifespans than the measuring transducers.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sensor and evaluation circuit are integrated as a single unit, then the structure is simpler and more compact, but the sensor must be replaced entirely when the evaluation circuit needs maintenance or updating, leading to loss of stored data and program code
Solution Approach 1:
The measuring arrangement is divided into separate functional modules: the sensor unit and the evaluation circuit are physically separated and connected via a plug connection. This segmentation allows independent replacement of the evaluation circuit while preserving the sensor and its associated data, directly resolving the contradiction between structural simplicity and information preservation.
2Adaptability or versatility
If the sensor is replaced frequently, then the measuring transducer can be updated, but data and program code specific to the measuring point are lost
Solution Approach 1:
By separating the sensor from the evaluation circuit through a plug connection, the system allows frequent sensor replacement without affecting the evaluation circuit that holds the measuring point data. The plug connection ensures data persistence in the evaluation circuit while enabling adaptable sensor changes.
Solution Approach 2:
The plug connection acts as an intermediary interface between the sensor and evaluation circuit, enabling easy disconnection and reconnection while maintaining the integrity of stored data in the evaluation circuit. This mediator allows sensor replacement without data loss.
3Duration of action of moving object
If the electronics are integrated into the sensor, then the sensor lifespan is limited by the electronics, but separating them increases device complexity
Solution Approach 1:
The sensor and evaluation circuit are segmented into separate replaceable units connected by a plug interface. This allows the sensor to be replaced when its lifespan expires while the evaluation circuit with longer lifespan can be retained, extending the overall system lifespan without excessive complexity.
Solution Approach 2:
The sensor is designed as a disposable or frequently replaceable component with a shorter lifespan, while the more expensive evaluation circuit is retained. This approach is economically efficient as only the cheaper sensor needs replacement, not the entire integrated unit.
4Loss of information
If the evaluation circuit is separated from the sensor, then the sensor can be replaced without losing data, but the connection and data transmission become more complex
Solution Approach 1:
The plug connection is designed as a universal interface that handles multiple functions: electrical connection for power and signal transmission, and mechanical coupling for secure attachment. This multi-functional interface simplifies the overall complexity despite the separation of components.
