Solution Overview
Problem
Existing air purifiers face challenges in separating and managing the booster unit, which is difficult to detach and adjust, leading to stability issues and noise due to its fixed structure.
Innovation Solution
An air purifier design featuring a booster coupler that allows the booster to be easily separated and adjusted, with a stable coupling mechanism that includes a fixation body and movable protrusions for directional change, along with a terminal connection for power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the booster is fixed to the body with a rigid coupling structure, then the stability of the product is improved, but the ease of separation and management by the user deteriorates
Solution Approach 1:
The coupling structure is divided into a fixation body (fixed to the body) and a movable body (attached to the booster). This segmentation allows the booster to be easily separated by detaching the movable body, while the fixation body remains stable on the body, resolving the contradiction between stability and ease of separation.
Solution Approach 2:
The movable body is designed to be movable relative to the fixation body, allowing it to move between a first position (coupled state) and a second position (separated state). This dynamic design enables the user to easily separate the booster when needed, while maintaining stability when coupled.
2Stability of the object's composition
If the booster is fixed in a fixed structure, then the product stability is improved, but the ease of adjustment and management deteriorates
Solution Approach 1:
The movable body can move between a first position (where it engages with the booster for stable coupling) and a second position (where it releases the booster for adjustment). This dynamic mechanism provides both stability during operation and ease of adjustment when needed.
Solution Approach 2:
The movable body acts as an intermediary between the fixed fixation body and the booster. It provides the necessary coupling force for stability while allowing the user to easily adjust or separate the booster by moving the intermediary component.
3Ease of operation
If the booster is easily separated from the body, then the ease of management is improved, but the product stability deteriorates
Solution Approach 1:
The coupling structure is segmented into a fixation body (providing stable attachment to the body) and a movable body (providing easy separation). The fixation body ensures product stability remains intact, while the movable body enables easy management and separation by the user.
4Stability of the object's composition
If the coupling structure is complex to ensure stable positioning, then the product stability is improved, but the device complexity increases
Solution Approach 1:
The coupling structure is divided into two simple components: a fixation body with a vertical protrusion and a movable body with horizontal protrusions. This segmentation simplifies each individual component while achieving stable positioning through their interaction, reducing overall device complexity.
Solution Approach 2:
The movable body is designed to be movable by the user without requiring additional tools or complex mechanisms. The spring provides automatic resetting force, and the geometric constraints of the protrusions provide self-aligning and self-locking features, reducing the need for complex control systems.

AI summary
The present disclosure relates to an air purifier. The air purifier of the present disclosure includes: a body having an inlet formed on an 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 through the outlet. The body includes a booster coupler which couples the booster to the body or decouples the booster from the body. The booster coupler includes a fixation body including a vertical protrusion which protrudes to an upper side so as to be inserted into one side of the booster, and a movable body movably disposed in the fixation body. The movable body includes a plurality of horizontal protrusions which protrude in a movement direction and which are inserted into the booster.
