Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of sensor carriers are used to accommodate different pressure sensors, then the adaptability to different measuring tasks is improved, but the device complexity and inventory requirements increase
Solution Approach 1:
The sensor carrier is designed with a universal seat structure that can accommodate multiple types of pressure sensors (e.g., piezoelectric, piezoresistive, capacitive sensors) through a single standardized interface. The seat includes a recess with a sealing surface and mounting features that work with different sensor geometries, eliminating the need for multiple specialized carrier types while maintaining adaptability to various measuring tasks
2Adaptability or versatility
If multiple types of sensor carriers are used to accommodate different pressure sensors, then the adaptability to different measuring tasks is improved, but the loss of time for assembly and adaptation increases
Solution Approach 1:
The sensor carrier is pre-configured with a standardized seat structure during manufacturing that is ready to receive different pressure sensor types without requiring additional adaptation steps. The seat includes pre-formed sealing surfaces, mounting features, and alignment elements that enable direct installation of various sensors, eliminating time-consuming assembly modifications
Solution Approach 2:
The universal seat design allows any pressure sensor type to be installed using the same mounting procedure and tools, standardizing the assembly process across different sensor variants and reducing the time required for adaptation to different measuring tasks

AI summary
A pressure measuring instrument having a sensor carrier, a casing, a plug connector, evaluation electronics, and a pressure sensor. The sensor carrier supports the pressure sensor adapted to output a pressure-proportional, electrically detectable pressure signal. The sensor carrier has a base body, a pressure terminal formed together with the base body to be connected to the source of the pressure to be detected, and a seat having several different circle geometries, each having an annular surface adapted for mounting a pressure sensor. The pressure terminal has a connecting channel opening inside the seat, and the annular surfaces of the individual circle geometries are axially staggered with respect to the port of the connecting channel, wherein the annular surface having the smallest diameter is closest to the connecting channel port.
