Circular Air Cleaner Filter Assembly with Nested Segmented Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mechanical air cleaning apparatuses face challenges in effectively removing viruses and germs, and replacing filters of different sizes is difficult, with existing air cleaning apparatuses also lacking in aesthetic appeal and user-friendly filter replacement mechanisms.
Innovation Solution
The air cleaner features a circular filter assembly with three stacked filters - a superfine filter, a HEPA filter, and a deodorization filter - with flush edges and distinct colors for easy identification, along with a design that includes a metal front panel for aesthetic appeal and a cleanliness display module using light colors to indicate air quality, and a three-point bottom support for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple filters of different sizes are used to effectively remove various pollutants, then filtration effectiveness is improved, but filter replacement difficulty increases
Solution Approach 1:
The filter assembly is segmented into three distinct filters (superfine filter, HEPA filter, and deodorization filter) that can be replaced as separate units. Each filter is designed with specific coupling protrusions and holes that allow individual removal and replacement, enabling users to replace only the specific filter that needs maintenance while keeping the other filters in place.
Solution Approach 2:
The filters are arranged in a nested configuration where the first filter is disposed inside the second filter, and the second filter is disposed inside the third filter. This nested structure allows each filter to be independently accessed and replaced while maintaining the compact overall assembly, solving the problem of replacing different-sized filters efficiently.
2Volume of moving object
If a compact filter assembly design is used to save space, then device size is reduced, but filter identification and replacement ease deteriorates
Solution Approach 1:
Each filter frame is assigned a distinct color (first frame: first color, second frame: second color, third frame: third color) to enable easy visual identification. This local quality differentiation allows users to quickly identify which filter needs replacement without having to disassemble the compact nested structure, maintaining both compactness and usability.
Solution Approach 2:
The filter frames utilize different colors to provide visual cues for filter identification and replacement status. The color coding system allows users to easily distinguish between the superfine filter, HEPA filter, and deodorization filter, making the compact filter assembly user-friendly despite its space-efficient design.
3Ease of manufacture
If basic functional design is used to reduce manufacturing complexity, then manufacturing cost is reduced, but aesthetic appeal deteriorates
Solution Approach 1:
The air cleaner employs a circular/cylindrical overall shape with curved surfaces, creating an aesthetically pleasing appearance. The circular filter frames and cylindrical case structure provide visual appeal while maintaining manufacturing simplicity through standardized curved component production.
Solution Approach 2:
The device combines metal materials for the front panel and case with plastic materials for the filter frames and internal components. This composite material approach enhances aesthetic appeal through the premium look of metal surfaces while keeping manufacturing complexity manageable through the use of molded plastic parts.

AI summary
An air cleaner is provided. The air cleaner may include a circular filter assembly, in which a plurality of filters may be stacked, a circular rear or first case including a mount sleeve, on which the filter assembly may be mounted, a circular middle or second case, on which a discharge grille may be disposed, the second case being coupled to a front or first surface of the first case, a circular front or third case coupled to a front or first surface of the second case, and a circular panel attached to a surface of the third case. The filter assembly may include a first filter, a second filter disposed at a side of the first filter to accommodate the first filter, and a third filter disposed at a side of the second filter to accommodate the second filter. Edges of surfaces of the first to third filters may be flush with each other.
