Smart Filter with Memory for Fluid Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid filtering systems lack effective monitoring and documentation capabilities to determine the remaining life and cause of premature filter failures, especially under varying environmental conditions.
Innovation Solution
A system that includes a manifold, a filter with a memory storage device, and sensors generating fluid parameter signals, which are used by a controller to position a filter valve to prevent fluid flow when predetermined conditions are met, allowing for real-time monitoring and data storage to assess filter status and environmental history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are associated with the filter to monitor status, then the ability to monitor filter status improves, but the cost and complexity of the system increases
Solution Approach 1:
The filter medium itself performs the sensing function by generating a detectable signal when degraded or damaged, eliminating the need for separate sensors. The filter monitors its own status through the signal it produces, reducing system complexity while maintaining monitoring capability
Solution Approach 2:
A detectable signal acts as an intermediary between the filter medium's physical state and the control system. This signal translates the filter's degradation state into a form that can be easily detected and processed, simplifying the overall system architecture
2Productivity
If the filter operates continuously to maintain filtration, then productivity is maintained, but the filter may fail prematurely due to environmental damage
Solution Approach 1:
The system continuously monitors the filter's status through the detectable signal and provides feedback to the control mechanism. When the signal indicates degradation or damage, the system automatically responds by shutting off fluid flow, preventing further damage and extending filter life while maintaining productivity through timely intervention
Solution Approach 2:
The filter medium generates a detectable signal in advance when it approaches a degraded or damaged state, allowing the system to take preliminary action to shut off flow before actual failure occurs. This preventive approach extends filter life and prevents premature failure
3Reliability
If the filter is protected from environmental conditions to extend life, then reliability improves, but the filter cannot respond to real-time environmental changes
Solution Approach 1:
The filter medium provides real-time feedback about its environmental exposure through the detectable signal. This allows the system to adapt to changing environmental conditions by monitoring the filter's actual state and adjusting fluid flow accordingly, combining protection with real-time responsiveness

AI summary
A system and method for filtering a fluid includes a manifold and a filter releasably connected to the manifold that includes a memory storage device. A filter valve in fluid communication with the manifold has an open position that allows the fluid to flow through the filter and a shut position that prevents the fluid from flowing through the filter valve. A sensor in fluid communication with the manifold generates a fluid parameter signal reflective of a characteristic of the fluid flowing through the manifold. A controller receives the fluid parameter signal and positions the filter valve to the shut position when the fluid parameter signal meets a predetermined fluid condition.
