Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are integrated directly into the engine lubrication system, then monitoring reliability is improved, but device complexity and manufacturing cost increase substantially
Solution Approach 1:
The patent introduces an adapter assembly as an intermediary component that interfaces between the existing engine lubrication system and the sensor. The adapter includes a body with a first end that engages the engine and a second end that engages the sensor, allowing monitoring functionality to be added without modifying the engine itself. This mediator approach resolves the contradiction by enabling reliable monitoring while avoiding the complexity of direct sensor integration into the engine.
2Adaptability or versatility
If the engine is redesigned to accommodate sensors, then monitoring capability is improved, but manufacturing cost increases substantially
Solution Approach 1:
The patent segments the monitoring function from the engine by using a separate, removable adapter assembly. The adapter body, fastener, and sensor are distinct components that can be added to existing engines without redesigning the engine itself. This segmentation allows monitoring capability to be added while maintaining the original engine manufacturing processes, thus avoiding increased manufacturing costs.
Solution Approach 2:
The adapter assembly is designed as a universal interface that can be applied to multiple engine types without requiring engine-specific modifications. The adapter body engages with standard engine features, and the fastener system provides secure mounting. This universal design enables monitoring capability across different engine models while avoiding the need for costly redesigns for each specific engine type.
3Measurement precision
If sensors are placed in the oil stream, then measurement precision is improved, but ease of operation deteriorates due to difficult installation
Solution Approach 1:
The adapter assembly serves as a mediator that provides easy access to the oil stream for sensor placement. The adapter body engages with the engine lubrication system and includes features that guide and secure the sensor in the optimal position within the oil flow. This intermediary structure makes sensor installation straightforward while ensuring the sensor remains in close proximity to the oil stream for precise measurements.
4Adaptability or versatility
If existing engines are modified to add monitoring, then adaptability is improved, but device complexity increases
Solution Approach 1:
The monitoring system is segmented into modular components: an adapter body, a fastener assembly, and the sensor itself. The adapter body is a standalone component that interfaces with the engine, and the fastener provides a simple mechanical connection for the sensor. This segmentation allows the monitoring functionality to be added to existing engines without increasing overall system complexity, as each component performs a single, well-defined function.

AI summary
A working fluid monitoring system for monitoring a working fluid of working fluid system of a piece of equipment is provided. The working fluid monitoring system can include a filter member having an inlet, an outlet, and a filter media disposed between the inlet and the outlet. The filter member can be configured to permit fluid communication of the working fluid of the working fluid system from the inlet, through the filter media, and out the outlet of the filter member. A sensor is in operable communication with the working fluid within the filter member and is configured to monitor in situ a parameter of the working fluid and/or the working fluid system.
