Fuel Filter Purging Assembly with Integrated Impurity Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuel filter housings require manual, often inaccessible visual checks to determine when impurities have built up, leading to potential inefficiencies and overlooked purging needs.
Innovation Solution
An integrated sensor within a purging assembly, positioned between sealing elements, detects impurity accumulation and provides electrical connectivity for automatic alerts, allowing for timely purging and monitoring of fuel state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual visual checks are used to determine when impurities have built up, then the filter housing can be monitored, but the process becomes difficult and unreliable when the housing is not easily accessible
Solution Approach 1:
The patent replaces the manual mechanical visual inspection system with an automated sensor-based detection system. The sensor integrated into the purging assembly detects impurity levels automatically, eliminating the need for manual access to the filter housing while maintaining reliable detection capability.
Solution Approach 2:
The purging assembly with integrated sensor performs self-monitoring of impurity levels in the filter housing. The system automatically detects when purging is needed and can trigger alerts without requiring manual intervention, enabling the system to serve itself in monitoring its own state.
2Loss of information
If manual visual checks are performed, then impurity accumulation can be detected, but the checks are easily overlooked and require human intervention
Solution Approach 1:
The sensor integrated into the purging assembly provides continuous feedback about impurity levels in the filter housing. When impurities reach a threshold level, the sensor triggers alerts or notifications, ensuring that information about impurity accumulation is not lost and automated monitoring is maintained.
Solution Approach 2:
The manual inspection process is replaced with an automated sensor system that continuously monitors impurity levels and provides electronic feedback, eliminating human intervention from the monitoring process and preventing overlooked checks.
3Measurement precision
If the sensor is positioned between the upper and lower sealing elements, then water detection accuracy is improved, but the sensor position becomes more constrained
Solution Approach 1:
The patent applies local quality by positioning the sensor at a specific location between the upper and lower sealing elements where water accumulation is most likely to occur. This localized positioning optimizes detection precision for the critical area without requiring complex positioning mechanisms throughout the entire assembly.
