Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate recirculation filter and chemical filter are used, then both particulate and chemical contaminants can be adsorbed, but device complexity increases
Solution Approach 1:
The patent combines the functions of separate recirculation filter (for particulate contaminants) and chemical filter (for chemical contaminants) into a single integrated filter element. This filter element comprises activated carbon fibers that simultaneously provide both particulate filtration and chemical adsorption capabilities, thereby reducing device complexity while maintaining comprehensive contaminant removal
Solution Approach 2:
The filter element is designed with multi-functionality to handle both particulate and chemical contaminants within a single component. The activated carbon fiber structure provides universal contaminant removal by combining mechanical filtration properties with chemical adsorption properties, eliminating the need for multiple specialized filters
2Object-affected harmful factors
If traditional polyamide filter is used, then particulate contaminants can be filtered, but chemical contaminant adsorption is insufficient
Solution Approach 1:
The patent changes the material parameters of the filter by using activated carbon fibers instead of traditional polyamide materials. This material substitution fundamentally alters the chemical properties of the filter, enabling high-level chemical contaminant adsorption through the activated carbon's porous structure and surface chemistry, while maintaining particulate filtration capabilities

AI summary
A data storage system includes a housing, one or more data storage media disposed within the housing, and an filter comprising activated carbon fibers disposed within the housing. The activated carbon fiber filter includes activated carbon fibers configured to adsorb both chemical contaminants and particulate contaminants within the housing. The activated carbon fiber filter may include a wide variety of active molecular functional groups, pores with sizes from macroscopic to nanoscopic scales, and a very high surface area per unit mass, in various embodiments. The activated carbon fiber filter may be mounted in a region of the data storage system having enhanced fluid pressure when the data storage system is in normal operation.
