Air Circulator Attachment Design for Easy Detachment and Firm Sealing

Solution Overview

Problem

Conventional air circulators used in air circulation-type mats and air conditioned outer wears are difficult to attach and detach from sheet members, affecting their air conditioning effectiveness and usability.

Innovation Solution

An air circulator design featuring a fan main body with a hollow cylinder unit, flange, motor fixing unit, and wing, along with a flexible ring member with engaging units, allowing easy attachment and detachment by utilizing the ring's flexibility to secure the fan to the sheet member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the air circulator is firmly attached to the sheet member to prevent air leakage and ensure air conditioning effectiveness, then the air conditioning performance is improved, but the ease of detachment for washing and maintenance deteriorates

Engineering Contradiction:

Improveair conditioning effectivenessVSAvoidease of detachment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The attachment structure is divided into separate components: the ring member with engaging units on the air circulator, and corresponding engaging units on the sheet member. This segmentation allows the air circulator to be firmly attached during use while enabling easy detachment when needed for washing or maintenance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment mechanism transitions from a static permanent bond to a dynamic reversible connection. The engaging units can be engaged to provide firm attachment for air conditioning effectiveness, and disengaged to allow easy detachment for washing and maintenance through simple manual operation.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the air circulator is easily detachable from the sheet member for washing and maintenance, then the ease of operation is improved, but the firmness of attachment to prevent air leakage deteriorates

Engineering Contradiction:

Improveease of attachment and detachmentVSAvoidattachment firmness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The attachment structure is divided into separate components: the ring member with engaging units on the air circulator, and corresponding engaging units on the sheet member. This segmentation allows the air circulator to be firmly attached during use while enabling easy detachment when needed for washing or maintenance.

Inventive Principle:

Solution Approach 2:

The attachment mechanism transitions from a static permanent bond to a dynamic reversible connection. The engaging units can be engaged to provide firm attachment for air conditioning effectiveness, and disengaged to allow easy detachment for washing and maintenance through simple manual operation.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If a simple attachment structure is used for the air circulator, then the device complexity is reduced, but the reliability of firm attachment to prevent air leakage deteriorates

Engineering Contradiction:

Improveattachment structure complexityVSAvoidattachment firmness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The attachment structure is divided into separate components: the ring member with engaging units on the air circulator, and corresponding engaging units on the sheet member. This segmentation allows the air circulator to be firmly attached during use while enabling easy detachment when needed for washing or maintenance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The ring member acts as an intermediary component that provides the engaging units for attachment. This simple intermediary structure enables both firm attachment for reliability and easy detachment for maintenance, resolving the contradiction between simple structure and reliable attachment.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An air circulator which is attached to a sheet member and which is for generating an air flow from one side of the sheet member to another side of the sheet member includes a fan main body and a ring member for attaching the fan main body to the sheet member. The fan main body includes a hollow cylinder unit, a flange formed on the cylinder unit, a motor fixing unit, a motor fixated to the motor fixing unit, a wing attached to a rotating shaft of the motor and first engaging units formed on outer surfaces of first parts of the cylinder unit, the first parts forming a pair and facing each other. The ring member includes second engaging units which are formed on inner surfaces of second parts that form a pair, the second parts facing each other, and which engage with the first engaging units.
