Air Purifier with Replaceable Filter and Volatile Substance Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purification devices only purify air without diffusing volatile substances, and they can lose filtering capability over time if the filter is not replaced promptly.
Innovation Solution
An air purification device with a replaceable part that houses a filter and material with volatile substances, allowing for simultaneous air purification and diffusion of fragrances or insecticides, with a design that ensures timely filter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional air purification device with a fixed filter is used, then air purification is achieved, but the filtering capability is lost over time if the filter is not replaced promptly
Solution Approach 1:
The device is divided into a permanent casing and a replaceable part. The filter is integrated into the replaceable part, which can be easily detached and replaced. This segmentation allows users to replace only the filter component without replacing the entire device, maintaining filtering capability while minimizing time and effort for maintenance.
Solution Approach 2:
The filter in the replaceable part is designed as a consumable component with a limited service life. When the filter becomes saturated or damaged, the entire replaceable part is discarded and replaced with a new one. This approach ensures continuous air purification capability while making filter replacement simple and cost-effective.
2Adaptability or versatility
If a conventional air purification device is used, then air purification is achieved, but volatile substances such as fragrances or insecticides cannot be diffused
Solution Approach 1:
The replaceable part combines multiple functions: air filtration through the filter and volatile substance diffusion through the material with volatile substances. By merging these functions into a single replaceable component, the device achieves versatility (air purification plus fragrance/insecticide diffusion) without significantly increasing overall device complexity, as both functions share the same structural platform.
Solution Approach 2:
The replaceable part is designed to perform multiple functions simultaneously: filtering particles from air and diffusing volatile substances. This multi-functionality allows the device to adapt to different needs (purification alone, or purification plus fragrance/insecticide) by simply replacing the part with different material compositions, without requiring separate devices or complex configuration changes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively purifies air while diffusing volatile substances, ensuring continuous operation by integrating a replaceable part that includes a new filter and volatile substance material, thus maintaining air quality and fragrance/insecticidal effects.
Implementation Method 1
a filter placed in front of said fan, such that air passes through said filter
Implementation Method 2
said replaceable part comprising material with volatile substances... allows the filtered air to mix with volatile substances
