Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air filters for clean rooms and confined environments are inefficient in removing both particle and airborne molecular contaminants, requiring separate systems that are cumbersome, bulky, and less effective due to limited activated material usage.
Innovation Solution
A combination particle and airborne molecular contaminant filter that integrates significant quantities of activated material into the pleated filter media construction, allowing intimate contact between air and activated material for enhanced contaminant removal, replacing traditional corrugated separators with activated material separators to increase efficiency and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate particle filter and AMC filter systems are used, then particle removal efficiency is improved, but device complexity and bulkiness increase
Solution Approach 1:
The patent combines particle filtration and AMC removal into a single integrated filter assembly where pleated filter media for particle removal and activated material beds for AMC removal are positioned adjacent to each other within the same housing, allowing both functions to be performed simultaneously without requiring separate filter systems
Solution Approach 2:
The filter assembly is designed to perform multiple functions - particle filtration through pleated media and AMC removal through activated material - within a single device structure, making the system universal for handling both types of contaminants in clean room environments
2Reliability
If significant quantities of activated material are used, then AMC removal effectiveness is improved, but filter volume and weight increase
Solution Approach 1:
The activated material beds are positioned within the same housing structure as the pleated filter media, with each layer nested adjacent to the other, maximizing the use of available space and allowing significant quantities of activated material to be incorporated without proportionally increasing overall filter volume
Solution Approach 2:
The filter design transitions from traditional linear arrangements to a multi-layered three-dimensional structure where activated material beds and pleated media are stacked adjacent to each other, effectively utilizing vertical and horizontal space to accommodate more activated material within a compact footprint
3Reliability
If activated material is used for pleat separation, then AMC removal is enhanced, but airflow resistance increases
Solution Approach 1:
The filter assembly is designed with alternating layers of pleated filter media and activated material beds, where each local region performs its specific function - particle filtration or AMC removal - allowing airflow to progress through the assembly with minimal overall resistance while maintaining effective contaminant removal at each stage
