Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling air diffusers in indoor settings lack integrated high-efficiency filtration and air purification capabilities, disrupting airflow systems when filtration is added and being bulky in smaller spaces, while portable units are conspicuous and inefficient.
Innovation Solution
A diffuser air purification unit that integrates high-efficiency particulate air (HEPA) filtration with ultraviolet light and bipolar ionization, allowing for standalone operation without HVAC ductwork, customizable to fit standard ceiling grids, and easily maintainable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filtration is added to existing ceiling diffusers, then air purification capability is improved, but airflow system operation is disrupted
Solution Approach 1:
The air treatment system is segmented into separate functional modules: a ceiling diffuser for air distribution and a portable air purifier for filtration and purification. This segmentation allows each component to perform its specialized function without interfering with the other, resolving the contradiction between adding purification capability and maintaining airflow system operation.
Solution Approach 2:
The portable air purifier acts as an intermediary device that handles all filtration and purification functions externally. It receives air from the ceiling diffuser, processes it through HEPA filters and UV-C lights, and returns purified air to the environment, thereby adding purification capability without disrupting the existing airflow system.
2Reliability
If portable air filtration units are used, then high-efficiency filtration is achieved, but space consumption and conspicuousness increase
Solution Approach 1:
The portable air purifier is designed to perform multiple functions within a single compact unit: HEPA filtration, UV-C sterilization, and bipolar ionization. This multi-functionality achieves high-efficiency air treatment without requiring multiple separate devices, thereby reducing space consumption while maintaining filtration efficiency.
Solution Approach 2:
The air purifier uses bipolar ionization technology that generates positive and negative ions to neutralize airborne pathogens and particles. This parameter change in air treatment methodology achieves high-efficiency purification in a compact form factor, reducing the need for extensive infrastructure.
3Reliability
If extensive infrastructure is installed for high-efficiency filtration, then filtration effectiveness is improved, but system complexity and cost increase
Solution Approach 1:
The complex filtration and purification functions are extracted from the ceiling diffuser and consolidated into a single portable air purifier unit. This extraction eliminates the need for extensive infrastructure modifications to the existing HVAC system while maintaining high filtration effectiveness through integrated HEPA filters and purification mechanisms.

AI summary
Disclosed herein is a diffuser air purification unit. The diffuser air purification unit can comprise a diffuser, a filtration chamber, a purification chamber, a blower, a housing, and a control module. The filtration chamber can be configured to receive air through the diffuser from an external setting in which the diffuser air purification unit is installed and to cause a filtration of the air when the air flows through the filtration chamber. The purification chamber can be configured to receive the air from the filtration chamber and to cause a purification of the air when the air flows through the purification chamber. The blower can be configured to intake the air from the external setting through the diffuser, the filtration chamber, and the purification chamber and to expel the air into the external setting. The housing can at least partially enclose the filtration chamber and the purification chamber. The control module can be secured to the housing and be configured to control an operation of the diffuser air purification unit.
