Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purification systems often struggle to effectively remove a wide range of pollutants, including bacteria, viruses, and fine dust, while also failing to provide adequate sterilization and efficient airflow management.
Innovation Solution
The air purification apparatus comprises a dual-module system, including an air purification module with a dust collection filter and a blower fan, and an air sterilization module with an ultraviolet light source and a fan. These modules are connected via a passage that allows air to flow between them, with a lighting portion and a partition wall structure to enhance functionality and prevent dust entry into the lighting area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single air purification module is used, then the device structure is simple, but it cannot effectively remove a wide range of pollutants including bacteria, viruses, and fine dust
Solution Approach 1:
The air purification apparatus is divided into two independent modules: a first air purification module with a dust collection filter for removing fine dust, and a second air sterilization module with an ultraviolet light source for sterilizing bacteria and viruses. Each module handles specific types of pollutants, allowing the system to effectively remove a wide range of pollutants while maintaining a modular and manageable structure.
2Reliability
If air purification and sterilization are performed in separate modules, then a wide range of pollutants can be removed, but the device complexity increases
Solution Approach 1:
The first air purification module and the second air sterilization module are merged into a single integrated apparatus with a unified housing structure. The modules share common components such as the housing, control unit, and power supply, allowing the system to maintain complex functionality for removing multiple pollutant types while avoiding excessive structural complexity through shared infrastructure.
3Productivity
If air flows directly from the first outlet to the second inlet, then airflow efficiency is high, but dust may enter the lighting area and accumulate
Solution Approach 1:
A partition wall structure is introduced as an intermediary element between the first outlet and the second inlet. This partition wall includes a first passage for air flow and a lighting portion with a light source. The partition wall mediates the air flow from the first outlet to the second inlet while preventing dust from entering the lighting area, thus maintaining airflow efficiency while eliminating the harmful effect of dust accumulation in the lighting area.
4Object-affected harmful factors
If a partition wall structure is added to prevent dust entry, then lighting quality is improved, but the device complexity increases
Solution Approach 1:
The partition wall structure serves multiple functions simultaneously: it prevents dust from entering the lighting area, provides a passage for air flow from the first outlet to the second inlet, and includes a light source for illuminating the connection passage. By making the partition wall multi-functional, the system improves lighting quality and prevents dust accumulation without adding excessive structural complexity, as one component performs multiple roles.

AI summary
An air purification apparatus may include: an air purification module, an air sterilization module, and a connection module connecting the air purification module and the air sterilization module to each other to enable air to flow therebetween, wherein the connection module may include a connection housing connecting the first housing and the second housing to each other and forms an exterior thereof, a connection passage provided to allow at least a portion of air discharged through the first outlet to be introduced into the connection housing and flow into the second passage through the second inlet, a lighting portion including a light source and a reflective surface, wherein the light source is arranged to surround a periphery of the connection passage, and the reflective surface is configured to reflect light irradiated by the light source and irradiate the light to outside of the connection housing, and a partition wall structure provided to block introduction of air between the lighting portion and the connection passage.
