Control unit for air purifier and air purifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air purifiers using filter technology face difficulties in maintenance and filter exchange due to fixed components, limited air intake area, and the use of plastic parts that emit pollutants like formaldehyde.
Innovation Solution
The air purifier design features a modular control unit with a slanting upper cover and attachment structure that allows for separate handling, combined with a filter unit that has a large air intake area and uses natural, recyclable materials, enabling easy maintenance and efficient air filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If components are fixedly attached to each other, then structural stability is improved, but ease of repair and maintenance deteriorates
Solution Approach 1:
The air purifier is divided into distinct modular components: a body, a filter unit, and a control unit. The control unit is further segmented into an upper cover, electronic equipment enclosure, and attachment structure. This segmentation allows individual components to be separated, accessed, and maintained independently while maintaining structural integrity when assembled.
2Device complexity
If filters are difficult to reach, then device compactness is improved, but ease of operation deteriorates
Solution Approach 1:
The filter unit is designed as a separate, accessible module with a removable bottom cover. The filter element is positioned within the body but can be easily accessed by removing the bottom cover, allowing users to exchange filters without disassembling the entire device or reaching into difficult locations.
3Volume of moving object
If total filter area is small, then device size is reduced, but productivity deteriorates
Solution Approach 1:
The filter element is designed with a multi-dimensional configuration including lateral surfaces and end surfaces that contribute to filtration. The air intake area is expanded by utilizing the lateral surface of the filter element, effectively increasing the total filtration area without proportionally increasing the device's overall volume.
4Device complexity
If air intake area is limited, then device compactness is improved, but productivity deteriorates
Solution Approach 1:
The air intake area is expanded by utilizing the lateral surface of the filter element as an additional intake surface. This three-dimensional approach to air intake allows the device to maintain a compact form factor while providing sufficient air intake area for effective purification.
5Ease of manufacture
If plastic parts are used, then ease of manufacture is improved, but object-generated harmful factors worsen
Solution Approach 1:
The material composition of key components is changed from plastic to natural materials. The upper cover is made of wood and the flat pane is made of glass, eliminating the source of formaldehyde emissions while maintaining aesthetic appeal and structural integrity. This material substitution addresses the harmful emissions issue while preserving manufacturability.
