Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid regulators face issues with filter clogging, which reduces the effectiveness of pressure regulation due to particulate accumulation, leading to decreased flow and increased wear on system components, with current solutions requiring noticeable degradation before filter maintenance is performed.
Innovation Solution
Incorporation of a detector system with measurement points upstream and downstream of the filter to measure pressure differences, providing visual or electronic alerts to operators about filter clogging, enabling timely maintenance and optimizing filter life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a filter is disposed before the orifice to reduce particulate, then the wear and erosion on process control system components is reduced, but the filter becomes clogged or saturated with dirt, oil and debris, decreasing fluid flow through the regulator
Solution Approach 1:
The patent applies preliminary action by implementing a detector that monitors filter condition before significant clogging occurs. The detector measures parameters such as pressure differential across the filter or particulate concentration in the fluid, providing early warning signals that enable proactive filter maintenance before flow restriction becomes problematic.
2Ease of repair
If operators change filters after noticeable impact has occurred, then maintenance is performed, but pressure regulation effectiveness is already degraded and system operation is disrupted
Solution Approach 1:
The patent implements feedback by using a detector that continuously monitors filter condition and provides real-time information to operators. This feedback mechanism enables operators to change filters based on actual condition data rather than waiting for noticeable degradation, thereby maintaining pressure regulation effectiveness and avoiding system disruptions.
3Object-affected harmful factors
If the filter becomes congested with particulate, then particulate removal is improved, but the flow of process fluid through the filter decreases
Solution Approach 1:
The detector enables preliminary action by identifying when the filter reaches an optimal replacement point before excessive particulate accumulation restricts flow. This allows operators to replace filters proactively, maintaining both effective particulate removal and adequate fluid flow through the regulator.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The detector system effectively alerts operators to filter clogging, allowing for proactive maintenance, reducing operational disruptions and extending filter life, thus maintaining consistent fluid pressure and system efficiency.
Implementation Method 1

AI summary
Example pressure regulators with filter condition detectors are described herein. In one example described here, a regulator includes a body having an inlet and an outlet and a flow control member interposed between the inlet and the outlet to regulate a fluid pressure at the outlet. The example regulator also includes a filter disposed between the inlet and the flow control member and a detector having a first measurement point upstream from the filter and a second measurement point downstream from the filter and upstream from the flow control member.
