Solution Overview

Problem

Industrial air filtering plants face efficiency drops and potential malfunctions due to the use of non-genuine cartridges, which can lead to premature wear and damage, affecting filtration efficiency and plant reliability.

Innovation Solution

A cartridge monitoring system using radio frequency identification (RFID) devices embedded within cartridges to authenticate their genuineness, integrated with a radio frequency communication system and processing means within the air filtering plant, ensuring only certified cartridges are used, thereby preventing malfunctions and maintaining high filtration efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If non-genuine cartridges are used to reduce costs, then initial acquisition cost is reduced, but reliability and filtration efficiency deteriorate due to premature wear and malfunctions

Engineering Contradiction:
Improvefiltering plant reliabilityVSAvoidcartridge authentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary verification of cartridge authenticity before the cartridge is installed and used. The RFID reader detects the RFID tag embedded in the cartridge during installation, and the processing unit verifies the authenticity code stored in the tag. This preliminary action prevents non-genuine cartridges from being used, thereby ensuring reliability without requiring continuous monitoring during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

An RFID tag embedded in the cartridge serves as an intermediary carrier of authenticity information. The tag contains an authenticity code that mediates between the cartridge and the verification system. The RFID reader reads this code, and the processing unit verifies it against stored genuine cartridge codes, enabling authentication without direct physical inspection or complex testing procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If continuous monitoring and verification of cartridge authenticity is implemented, then reliability is improved, but device complexity and initial cost increase

Engineering Contradiction:
Improvefiltration efficiencyVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The RFID reader and processing unit serve multiple functions: they verify cartridge authenticity, track cartridge installation and removal, and provide information for maintenance scheduling. This multi-functionality reduces the need for separate monitoring systems and minimizes overall system complexity while comprehensively addressing filtration efficiency requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically verifies cartridge authenticity and tracks usage without requiring manual intervention. The RFID reader automatically detects cartridges when installed, the processing unit automatically verifies authenticity codes, and the system automatically manages verification records. This self-service operation reduces operational complexity and ensures consistent filtration efficiency monitoring.

Inventive Principle:
Principle #25Self-service
