Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing facilities face challenges in effectively reducing atmospheric pollution due to the simultaneous emission of particulate and gaseous pollutants, which worsens indoor air quality and leads to equipment malfunctions. Existing air purifiers are inadequate for removing ultrafine particles and gaseous pollutants, and it is difficult to determine when they need replacement.
Innovation Solution
A system comprising a particulate pollutant processor, a gaseous pollutant preprocessor, high and low concentration processing filter units, and sensors to measure pollution concentrations. This system selectively routes exhaust gases through different processing units based on pollution levels, allowing for efficient removal of both particulate and gaseous pollutants, and includes a mechanism to alert when the air purifying module needs replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional air purifiers with filter nets are used in printing devices, then they can remove some particulate pollutants, but they are insufficient for removing ultrafine particles and gaseous pollutants
Solution Approach 1:
The air purification system is divided into three distinct modules: a particulate pollutant processor for removing particles, a gaseous pollutant preprocessor for treating gases, and a filter unit for final filtration. Each module targets specific pollutant types, allowing comprehensive purification without requiring a single complex device
Solution Approach 2:
The gaseous pollutant preprocessor acts as an intermediary component between the particulate pollutant processor and the filter unit. It preprocesses gaseous pollutants before they reach the filter, preventing filter clogging and extending filter life while maintaining effective gas removal
2Ease of operation
If fans are used to expel exhaust gases from printing devices, then they can improve indoor air circulation, but they spread pollutants widely inside the printing facility
Solution Approach 1:
The harmful function of the fan (spreading pollutants) is separated from its useful function (air circulation). Pollutants are extracted and removed through dedicated purification modules before air is circulated back into the facility, allowing the fan to operate without distributing contaminants
3Productivity
If air is expelled without being purified, then it can improve air flow, but the air around the printing facility is polluted
Solution Approach 1:
Air purification is performed as a preliminary action before exhaust gases are expelled from the facility. The particulate pollutant processor, gaseous pollutant preprocessor, and filter unit work together to clean air before discharge, ensuring high-speed air exchange does not result in external pollution
4Ease of manufacture
If conventional filter nets are used in air purifiers, then they can provide basic filtration, but it is difficult to determine when they have reached the end of their service life
Solution Approach 1:
A sensor provides feedback about air quality and filter status to the control unit. The control unit monitors this feedback and determines when the filter reaches the end of its service life, enabling timely replacement and maintaining optimal purification effectiveness
5Reliability
If multiple pollution processing units are installed to handle both particulate and gaseous pollutants, then pollutant removal effectiveness improves, but equipment installation costs and operation costs increase
Solution Approach 1:
The control unit provides universal control over multiple different pollution processing units, coordinating the particulate pollutant processor, gaseous pollutant preprocessor, and filter unit as an integrated system. This multi-functional control approach manages complexity while maintaining comprehensive pollutant removal capabilities
