Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large booster is used to discharge filtered air to upper areas, then air discharge performance is improved, but device size and bulkiness increase
Solution Approach 1:
The booster is divided into modular components: a booster case with front body, rear body, and circumferential body; a fan housing; and a rotatable booster fan. This segmentation allows each component to be optimized independently and assembled into a compact overall structure that maintains high air discharge performance while reducing total volume.
Solution Approach 2:
The booster fan is designed to rotate about an axis, enabling dynamic adjustment of air discharge direction in multiple dimensions. The bent discharge passage within the booster case further utilizes three-dimensional space to redirect airflow efficiently. This multi-dimensional approach allows a smaller booster to achieve the same air distribution effect as a larger fixed-direction booster.
2Device complexity
If air is discharged only to the top, then structure is simple, but air distribution coverage is limited
Solution Approach 1:
The booster fan is designed to rotate about a horizontal axis, dynamically changing the discharge direction of filtered air from the body. This rotation capability allows the system to switch between discharging air upward, sideways, or in combination, significantly expanding air distribution coverage without adding multiple separate discharge structures, thus maintaining relative simplicity.
Solution Approach 2:
The single booster assembly performs multiple functions: it receives air from the body outlet, redirects it through the bent discharge passage, and distributes it in variable directions via fan rotation. This multi-functional design eliminates the need for separate discharge mechanisms for different directions, achieving wide coverage while keeping the overall structure compact and unified.

AI summary
The present disclosure relates to an air purifier.The air purifier includes: a body having an inlet formed on a circumferential surface thereof and an outlet formed on an upper surface thereof; and a booster disposed at an upper side of the body and switching a flow direction of air which flows to the upper side through the outlet. The booster includes a booster case having a booster inlet at one side facing the outlet and a booster outlet in an opposite direction to the booster inlet, and a booster fan rotatably disposed inside the booster case, and sucking air in a direction which is in line with a rotary axis and sending the air in a vertical direction to the rotary axis. An inner guide which guides the air flowing by the booster fan to the booster outlet is disposed at an inner side of the booster case.
