Solution Overview

Problem

Conventional systems for managing turbine intake filters do not effectively account for the heterogeneous conditions of filters, leading to inadequate or excessive cleaning, which can degrade performance and reduce operational life.

Innovation Solution

A system that includes a monitoring device to generate indications based on air flow through each filter, allowing for customized management tasks such as pulsing or replacement, tailored to the specific condition of each filter, using a control device and pulse valve to adjust cleaning parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single cleaning approach is used for all filters, then the cleaning process is simple to implement, but it is too weak for heavily soiled filters and too strong for lightly soiled filters, potentially damaging them

Engineering Contradiction:
Improvesimplicity of cleaning processVSAvoidfilter performance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The filter bank is divided into multiple segments or zones, each with its own cleaning control. The system segments the filtering system into individually controllable units, allowing customized cleaning for each segment based on its specific condition, thereby avoiding both insufficient and excessive cleaning while maintaining reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning system dynamically adjusts cleaning parameters based on real-time monitoring of filter conditions. Flow sensors continuously monitor air flow through each filter, and the control system dynamically modifies cleaning intensity and timing to match actual filter needs, optimizing both effectiveness and filter protection.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If conventional cleaning systems are used, then the system structure is simple, but they cannot account for heterogeneous filter conditions, leading to inadequate or excessive cleaning

Engineering Contradiction:
Improvecleaning system structureVSAvoidability to handle different filter conditions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system incorporates flow sensors that continuously monitor air flow through each filter and provide feedback to the control system. This feedback mechanism enables the system to detect filter loading conditions and automatically adjust cleaning operations, providing adaptability to heterogeneous filter conditions while maintaining reasonable system complexity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables filters to essentially self-regulate their own cleaning needs through continuous flow monitoring. Each filter's cleaning is triggered and controlled based on its own performance indicators (air flow reduction), allowing the system to adapt to different filter conditions without complex centralized control for each filter.

Inventive Principle:
Principle #25Self-service

3Productivity

If filters are cleaned too strongly, then cleaning effectiveness is high, but filter damage occurs reducing operational life

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidfilter operational life
Core Design Contradiction:
ProductivityVSDuration of action of stationary object

Solution Approach 1:

The system applies cleaning action only when and where needed, rather than uniformly to all filters. By monitoring individual filter conditions, the system applies partial cleaning to filters that need it and avoids excessive cleaning of filters that don't require it, thereby maintaining cleaning effectiveness while protecting filter lifespan.

Inventive Principle:
Principle #16Partial or excessive action

4Reliability

If filters are cleaned too weakly, then filter damage is avoided, but cleaning effectiveness is insufficient and filter performance degrades

Engineering Contradiction:
Improvefilter integrityVSAvoidcleaning effectiveness
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system changes cleaning parameters (timing, duration, intensity) based on monitored filter conditions. By adjusting these parameters dynamically, the system ensures cleaning is strong enough to be effective when needed while remaining gentle enough to protect filter integrity, resolving the contradiction between cleaning effectiveness and filter protection.

Inventive Principle:
Principle #35Parameter changes
