Buried Air Purifier Segmented Design for Small-Opening Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers with ventilation and purification functions are bulky due to large fans and motors, making them difficult to install and maintain through small openings, and they compromise aesthetic design.
Innovation Solution
A buried type air purifier with a main body that includes a fan accommodating part and a filter, designed to fit through a small opening, featuring a slim 'L'-shaped cross section, allowing for easy installation and maintenance, and includes ventilation and discharge passages with adjustable air flow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a large-sized fan and motor are used to generate sufficient intake power with low noise, then the air purification and ventilation performance is improved, but the device volume increases making it difficult to install through small openings
Solution Approach 1:
The device is divided into two distinct parts: a first main body part containing the fan and motor, and a second main body part with a smaller cross-sectional area. This segmentation allows the bulky components to be separated from the installation interface, enabling the device to pass through small openings while maintaining adequate power output.
Solution Approach 2:
The first main body part has a larger cross-sectional area parallel to the boundary surface, while the second main body part has a smaller cross-sectional area in the same direction. This dimensional variation along the length of the device allows it to fit through small openings despite containing large components.
2Power
If a large-sized fan and motor are used to generate sufficient intake power with low noise, then the air purification and ventilation performance is improved, but the aesthetic design is compromised due to bulky appearance
Solution Approach 1:
By segmenting the device into a bulky first main body part (containing fan and motor) and a slim second main body part (extending toward the use space), the aesthetic impact is reduced. The slim portion that is visible in the use space maintains good appearance while the bulky portion containing power components is positioned away from the aesthetic focal point.
3Shape
If the buried opening is made small to achieve a slim design, then the aesthetic appearance is improved, but after-sales service becomes difficult when parts such as the fan break down
Solution Approach 1:
The segmentation allows the fan and motor to be housed in the first main body part which can be accessed separately. The opening at the boundary between the first and second main body parts provides access to the fan and motor for maintenance and repair, while the second main body part maintains the slim profile for aesthetic purposes.
Solution Approach 2:
The opening between the first and second main body parts acts as an intermediary access point, allowing service personnel to reach the fan and motor components for maintenance without requiring a large buried opening, thus enabling repair through the slim design configuration.
4Ease of operation
If the cross-sectional area of the main body is reduced to fit through small openings, then the ease of installation is improved, but the space for accommodating the fan and motor is reduced
Solution Approach 1:
The device is segmented such that the first main body part has a larger cross-sectional area providing adequate space for the fan and motor, while the second main body part has a smaller cross-sectional area for easy installation through small openings. This segmentation resolves the contradiction by distributing different functional requirements to different parts of the device.

AI summary
A buried type air purifier including a main body to be buried in a buried space through a buried opening provided on a boundary surface between a use space and the buried space, the main body having an intake passage and a discharge passage which take in and discharge air, respectively; a fan to guide air of the use space along the intake passage and the discharge passage; and a filter to filter the air. The main body includes: a first main body part having a fan accommodating part to accommodate the fan; and a second main body part having a cross sectional area, which is parallel with the boundary surface, being smaller than the first main body part, where the second main body part is formed to pass the intake and discharge passages through which the air guided via the fan accommodated in the fan accommodating part passes.
