Solution Overview

Problem

Industrial processes requiring filtration of fluids at elevated temperatures face challenges with costly and time-consuming maintenance due to filter replacement and corrosion, necessitating a cost- and time-efficient basket strainer that adapts to varying particulate conditions.

Innovation Solution

A modular basket strainer designed with 3D-printed polymer modules, featuring adjustable pore sizes and threaded connections, allowing for easy assembly, maintenance, and customization to suit specific filtration needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional basket strainers are used, then filtration function is provided, but maintenance time and cost increase

Engineering Contradiction:

Improvefiltration functionVSAvoidmaintenance time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The basket strainer is divided into multiple detachable modules (first module, second module, third module) that can be separated and cleaned independently. Each module has connection features allowing them to be assembled and disassembled, enabling quick maintenance without replacing the entire strainer, thus reducing maintenance time while maintaining filtration reliability.

Inventive Principle:

Principle #1Segmentation

2Reliability

If traditional basket strainers are used, then filtration function is provided, but corrosion occurs

Engineering Contradiction:

Improvefiltration functionVSAvoidcorrosion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The material of the basket strainer modules is changed from traditional metals to polymer materials, fundamentally altering the chemical properties to resist corrosion. This material parameter change eliminates the harmful effect of corrosion while maintaining the structural integrity and filtration function of the strainer.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If fixed pore size basket strainers are used, then manufacturing is simplified, but adaptability to varying particulate conditions is reduced

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidadaptability to particulate conditions

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The strainer is segmented into multiple modules, each with standardized connection features. This allows different module configurations and pore size variations to be assembled based on specific particulate conditions, maintaining manufacturing simplicity through standardized components while achieving adaptability through modular arrangement.

Inventive Principle:

Principle #1Segmentation
