Air Filtration Blower Layout for Sensor Sampling and Low Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air treatment systems face challenges in maximizing efficiency while minimizing noise and size, and there is a need for improved air filtration systems that effectively address airborne pollutants and odors.
Innovation Solution
The air treatment system incorporates a sensor air passage that utilizes a low pressure region created by the blower to draw air through a filter, a filter frame with integral connectors for easy attachment, a blower with an angled screen for optimized airflow, and a remote control holder for convenient operation, along with a gasket for sealing between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the blower forces air out of the outlet to create a low pressure region, then ambient air is drawn through the sensor flow passage for contamination sensing, but this may increase system complexity and noise
Solution Approach 1:
The blower's exhaust air flow automatically creates the low pressure region needed to draw ambient air through the sensor passage, eliminating the need for a separate sampling pump or fan. The system uses its own operational byproduct (exhaust flow) to serve the sensing function.
Solution Approach 2:
The blower serves dual functions: primarily moving air through the filtration system, and secondarily creating the pressure differential needed for sensor air sampling. This multi-functionality reduces overall system component count and complexity.
2Volume of moving object
If multiple components (blower, filter, sensor, housing) are integrated into a compact system, then system size is minimized, but assembly and sealing complexity increases
Solution Approach 1:
The gasket integrates multiple sealing functions into a single component that seals between the blower and housing, simplifying assembly by reducing the number of separate sealing elements needed in the compact configuration.
Solution Approach 2:
The system is divided into modular components (blower assembly, filter assembly, housing sections) that can be manufactured separately and then assembled using the gasket and connector interfaces, making compact integration manageable.
3Productivity
If the screen is positioned at an angle relative to the blower intake, then airflow optimization is achieved, but manufacturing and alignment precision requirements increase
Solution Approach 1:
The screen is deliberately positioned at an asymmetric angle relative to the blower intake rather than being symmetrically aligned, optimizing airflow patterns to improve blower efficiency while the angle itself becomes a fixed design parameter.
Solution Approach 2:
The screen angle and position are pre-determined in the design phase and built into the housing structure, so that during assembly the screen simply needs to be installed in its predetermined position rather than requiring precision alignment during assembly.

Implementation Method 1
The air forced out of the blower outlet creates a low pressure region proximate to the sensor outlet to draw ambient air through the sensor flow passage
Implementation Method 2
A conventional particulate filter includes a substance, such as fiberglass or electret-type media, that traps particulate matter as air is passed therethrough
Implementation Method 3
A conventional odor filter includes activated carbon, or activated charcoal, which removes pollutants from the air primarily by adsorption
