Solution Overview

Problem

Existing air purifiers face challenges in separating the booster unit for stability and ease of user management, as it is often fixedly coupled to the body, making it difficult to handle and maintain.

Innovation Solution

The air purifier design allows the booster unit to be separably disposed at the upper portion of the body, with a booster coupler that enables easy detachment and reattachment, facilitating user-friendly management and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the booster is fixedly coupled to the body, then the stability of the product is improved, but the ease of operation for user management deteriorates

Engineering Contradiction:
Improveproduct stabilityVSAvoiduser management ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The air purifier is divided into separable modules: the body and the booster. The booster can be detached from the body through a coupling mechanism, allowing users to separately manage and maintain the booster while maintaining stability when coupled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling mechanism between the booster and body transitions from a fixed state to a separable state. The booster can be dynamically attached or detached based on user needs, enabling both stable operation and easy maintenance.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the booster is separably disposed, then the ease of operation for user management is improved, but the stability of the product deteriorates

Engineering Contradiction:
Improveuser management easeVSAvoidproduct stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

A coupling mechanism acts as an intermediary between the booster and body. This coupling structure enables easy attachment and detachment while providing stable connection when coupled, resolving the contradiction between separability and stability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the booster is fixedly coupled, then the product stability is improved, but the ease of repair deteriorates

Engineering Contradiction:
Improveproduct stabilityVSAvoidmaintenance accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The booster is designed as a separate module that can be detached from the body. This segmentation allows users to easily remove and maintain the booster without disassembling the entire air purifier, improving accessibility while maintaining stability when coupled.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling mechanism allows the booster to transition between fixed and separable states. When coupled, the structure is stable; when detached, the booster is easily accessible for maintenance, resolving the contradiction between stability and ease of repair.

Inventive Principle:
Principle #15Dynamics

AI summary

An air purifier may include a body having an inlet formed on a circumferential surface thereof and an outlet formed on an upper surface thereof, and a booster that is disposed at an upper side of the body and switches a flow direction of air flowing through the outlet. The body may include a booster coupler that couples the booster to the body or decouples the booster from the body. The booster coupler may include a fixation body including a vertical protrusion that 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 may include a plurality of horizontal protrusions that protrudes in a movement direction and which is inserted into the booster.
