Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large air filtration units required to mitigate air pollution in properties are space-consuming and difficult to maintain, especially in urban areas where space is limited, and existing solutions do not effectively address the need for localized filtration and easy maintenance.
Innovation Solution
An air vent assembly with a filter assembly that includes a chemisorption material, such as active carbon or impregnated activated alumina, is integrated into each room's ventilation system, allowing for localized filtration and easy access for maintenance, with the filter assembly being accessible from within the room and visible for saturation indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large filtration unit is installed to handle the entire air supply volume for the property, then the filtration effectiveness for PM2.5, PM10, and NOx pollutants is improved, but the space occupied and device complexity increase significantly
Solution Approach 1:
The patent divides the single large filtration unit into multiple smaller filtration units distributed throughout the property. Each filtration unit handles a portion of the air supply volume, specifically serving local areas or rooms. This segmentation reduces the size of each individual unit, eliminating the need for large dedicated spaces while maintaining overall filtration effectiveness across the entire property.
Solution Approach 2:
The patent implements local filtration at distributed points within the property rather than centralized filtration. Each filtration unit is sized appropriately for its local air supply requirements, allowing for optimized filtration performance in each zone without requiring oversized units that would consume excessive space.
2Reliability
If a large filtration unit is installed to handle the entire air supply volume, then the filtration effectiveness is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent segments the centralized filtration system into multiple decentralized filtration units. Each unit is independently sized for its specific air supply requirements, simplifying the overall system architecture. This segmentation reduces device complexity by eliminating the need for a single large, complex filtration unit while maintaining comprehensive filtration coverage through multiple simpler units.
3Reliability
If the filter unit is installed in a location with sufficient space, then the filtration performance is maintained, but the loss of usable property space increases
Solution Approach 1:
The patent divides the large filtration unit into multiple smaller units that can be installed in distributed locations throughout the property, such as utility areas, closets, or existing mechanical rooms. This segmentation allows filtration functionality to be integrated into existing spaces without requiring dedicated large areas, thereby maintaining filtration performance while preserving usable property space.

AI summary
An air vent assembly for a ventilation system comprises a main body and a filter assembly. The main body has an airflow conduit with an airflow inlet for connection to an air supply duct and an airflow outlet defining an air supply inlet for a room. Mounting means are provided for securing the main body to a surface such as ceiling so that the conduit is located within a vent aperture of said room. A filter assembly is connected to the main body such that airflow is channelled through the filtration unit prior to flowing through the outlet of the conduit. The filter assembly includes a chemisorption material filter such as an active carbon or an impregnated activated alumina.
