Solution Overview

Problem

Existing hazardous gas purification devices require separate manufacturing facilities and incur increased production costs due to differences in filter size and configuration between stand-type and mobile-type devices, and lack effective life-span prediction and intelligent laboratory management features.

Innovation Solution

A modularized hazardous gas purification device with a three-dimensional filter and life-span prediction module, integrated with an intelligent laboratory management system, allowing interchangeable installation between stand-type and mobile-type configurations, and featuring a four-way filtration structure and automatic fan operation based on reagent type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate filter designs are used for stand-type and mobile-type purification devices, then each device can be optimized for its specific vertical length, but manufacturing facilities must be separate and production costs increase

Engineering Contradiction:
Improvepurification performanceVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by designing a standardized filter module that can be installed in both stand-type and mobile-type purification devices. The filter module has uniform dimensions and connection interfaces that accommodate different device types, allowing a single manufacturing facility to produce filters for both applications without requiring separate production lines or tooling.

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

Solution Approach 2:

The purification system is segmented into a standardized filter module that can be independently manufactured and then installed in different device configurations. This modular approach separates the filter design from the overall device structure, enabling the filter to be produced once and reused across multiple device types.

Inventive Principle:
Principle #1Segmentation

2Duration of action of moving object

If a traditional linear filter structure is used, then the device structure is simple, but the filter life-span is limited and hazardous gases cannot be effectively dispersed

Engineering Contradiction:
Improvefilter life-spanVSAvoidfilter structure
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent transitions from a traditional linear one-dimensional filter structure to a three-dimensional multi-directional filter configuration. The filter module incorporates filtration elements arranged in multiple directions (upward, downward, lateral) creating a three-dimensional gas flow path that increases the effective filtration surface area and extends filter life-span by distributing the filtration load across multiple dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The filter module employs a nested structure where multiple filtration layers and flow paths are arranged concentrically or in stacked configurations within a compact housing. This nested arrangement maximizes the use of internal space, creates multiple gas flow paths through the filter media, and extends the effective life-span by providing redundant filtration capacity.

Inventive Principle:
Principle #7Nested doll (Nesting)
