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

VSEngineering 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

Engineering Contradiction:
Improveproduct stabilityVSAvoidease of separation
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveproduct stabilityVSAvoidadjustability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the booster is easily separated from the body, then the ease of management is improved, but the product stability deteriorates

Engineering Contradiction:
Improveease of managementVSAvoidproduct stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvepositioning stabilityVSAvoidcoupling structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #25Self-service

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.
