Solution Overview

Problem

Filter systems in industries like the paper industry face downtime and efficiency drops due to rogue materials plugging the system, making it difficult and time-consuming to find and remove these materials for normal operation.

Innovation Solution

A separator assembly with a chamber, screen, pulse jet assembly, and bleed-in assembly is used, where the pulse jet assembly selectively cleans the screen by directing a disrupting fluid, and the bleed-in assembly directs a bleed-in fluid to help clear blockages, allowing for efficient removal of solid materials and maintaining system efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a filter system operates continuously to maintain productivity, then system efficiency is improved, but rogue material accumulates on the screen causing blockages and requiring downtime for cleaning

Engineering Contradiction:

Improvesystem efficiencyVSAvoidoperational continuity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The pulse jet assembly performs preliminary cleaning action by directing disruptive fluid onto the screen to dislodge rogue material before it accumulates to blocking levels. This preventive maintenance approach allows the system to operate continuously while preventing blockages from developing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The filter system cleans itself through the automated pulse jet mechanism that periodically directs fluid onto the screen to remove accumulated material. This self-cleaning capability eliminates the need for manual intervention and maintains continuous operational reliability.

Inventive Principle:

Principle #25Self-service

2Reliability

If the filter system stops to remove rogue material from the screen, then blockages are cleared and system reliability is restored, but productivity decreases due to downtime

Engineering Contradiction:

Improvesystem operational statusVSAvoidsystem efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The pulse jet assembly enables continuous operation by maintaining screen clarity through periodic self-cleaning cycles. The useful action of filtering continues uninterrupted as the system automatically removes rogue material without requiring production stoppages.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The manual mechanical process of stopping production to physically remove material is replaced with an automated fluid-based pulse jet cleaning system. This substitution eliminates downtime while maintaining reliable operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If manual cleaning methods are used to remove rogue material, then the screen can be cleaned, but the process is time-consuming and labor-intensive

Engineering Contradiction:

Improvescreen cleanlinessVSAvoidcleaning duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Manual mechanical cleaning is replaced with an automated pulse jet system that uses disruptive fluid to remove material. This substitution dramatically reduces cleaning time and eliminates labor requirements while maintaining effective screen cleanliness.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cleaning process uses pneumatic or hydraulic principles by directing pressurized fluid through the pulse jet assembly onto the screen. This fluid-based mechanism provides rapid, efficient material removal compared to manual methods.

Inventive Principle:

Principle #29Pneumatics and hydraulics
