Air Purifier Angular Filter Layout to Reduce Housing Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers often require larger housings to accommodate multiple components like UV lights, fragrance diffusers, and odor absorbers, leading to unaesthetic design, increased manufacturing costs, and environmental impact.
Innovation Solution
An air purifier design with a front and rear housing, incorporating a first and second air filter, a UV light, an odor absorber, and a fragrance diffuser, where the second filter is mounted at an offset angle, reducing the overall size and material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components (UV light, fragrance diffuser, odor absorber) are integrated into air purifiers, then air purification effectiveness is improved, but housing size and material usage increase
Solution Approach 1:
The patent places the UV light, fragrance diffuser, and odor absorber inside the air purifying compartment in a nested arrangement around the filters. The UV light is positioned at the bottom between filters, the fragrance diffuser is mounted on cross bars extending from the top, and the odor absorber is positioned in front of the second filter, creating a compact nested configuration that maximizes space utilization.
Solution Approach 2:
The second air filter is mounted at an offset angle (5-15 degrees) relative to the first filter, creating a three-dimensional angular arrangement. This dimensional change allows components to be positioned in multiple spatial dimensions rather than linearly, reducing the overall housing volume required while maintaining effective air purification through all components.
2Reliability
If multiple components are integrated into air purifiers, then air purification effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The air purifying compartment serves multiple functions simultaneously: it houses both first and second air filters for particle filtration, a UV light for germicidal disinfection, a fragrance diffuser for air freshening, and an odor absorber for odor neutralization. This multi-functionality consolidates what would traditionally require separate devices into one unit, improving overall air purification effectiveness while avoiding the need for multiple separate housings and reducing total manufacturing cost.
Solution Approach 2:
By nesting the UV light, fragrance diffuser, and odor absorber within the same air purifying compartment as the filters, the patent eliminates the need for separate housings for each component. This nested configuration reduces the total material required for manufacturing multiple separate units and lowers assembly complexity, thereby reducing manufacturing costs while maintaining comprehensive air purification functionality.
3Reliability
If multiple components are integrated into air purifiers, then air purification effectiveness is improved, but aesthetic appeal decreases
Solution Approach 1:
The compact nested arrangement of components within the rear housing creates a sleek, space-efficient design. By positioning the UV light at the bottom, the fragrance diffuser on top cross bars, and the odor absorber in front of the second filter, the patent achieves a clean internal configuration that translates to a more compact external housing, improving aesthetic appeal while maintaining all purification functions.
Solution Approach 2:
The angular mounting of the second filter at 5-15 degrees relative to the first filter creates a three-dimensional configuration that optimizes space utilization. This dimensional arrangement allows for a more compact and ergonomically designed housing shape, improving aesthetic appeal and transportability while ensuring all components are effectively positioned for comprehensive air purification.
4Adaptability or versatility
If larger housing is used to accommodate multiple components, then component integration is improved, but transportability decreases
Solution Approach 1:
The nested configuration of the UV light, fragrance diffuser, and odor absorber within the air purifying compartment creates a compact overall housing size. The UV light is positioned at the bottom between filters, the fragrance diffuser is mounted on cross bars extending from the top, and the odor absorber is positioned in front of the second filter, achieving efficient space utilization that enhances transportability while maintaining full component integration.
Solution Approach 2:
By mounting the second air filter at an offset angle (5-15 degrees) relative to the first filter, the patent creates a three-dimensional angular arrangement that optimizes internal space. This dimensional configuration reduces the external dimensions of the housing required to accommodate all components, thereby improving transportability and storage efficiency while maintaining effective integration of all air purification components.
