Solution Overview

Problem

Traditional hair dryer attachments lack versatility and quality in diffusing surfaces and features, making it difficult for users to achieve desired hair results, and are often bulky and hard to attach/detach.

Innovation Solution

A diffuser attachment with a smooth, curved diffusing surface and a hair engagement cover with prongs that extend outward, allowing for multiple configurations to suit different hair styling operations, including a grid configuration of discharge openings and bridge threads for airflow expulsion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional hair diffusers use a single surface or feature to diffuse hair, then the structure is simple, but the versatility to offer various diffusing surfaces and features is limited

Engineering Contradiction:

Improveversatility of diffusing surfaces and featuresVSAvoidcomplexity of attachment structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment is divided into a base diffuser component and a removable cover component. The cover can be detached and replaced with different covers featuring various surfaces and features (smooth, textured, with prongs, without prongs), allowing users to switch between different diffusing configurations without changing the entire attachment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base diffuser attachment serves as a universal platform that can accommodate multiple different covers. Each cover provides different diffusing functions (smooth surface for sleek styling, textured surface for volume, prongs for root lifting), making the single base attachment multi-functional through its compatibility with various covers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If conventional attachments are made bulky to provide multiple features, then the versatility is improved, but the ease of storage and attachment/detachment is worsened

Engineering Contradiction:

Improveversatility of diffusing optionsVSAvoidease of attachment and detachment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

By separating the attachment into a compact base and removable covers, each component can be small and lightweight. The covers snap onto the base quickly and can be easily removed and replaced, making the system both versatile and easy to operate despite having multiple configuration options.

Inventive Principle:

Principle #1Segmentation

3Manufacturing precision

If current attachments use a non-smooth concave surface, then the structure is simpler to manufacture, but the quality of diffusing results is reduced

Engineering Contradiction:

Improvesmoothness of diffusing surfaceVSAvoidcomplexity of surface fabrication

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

Different covers provide different surface qualities tailored to specific styling needs. The smooth surface cover is manufactured with high precision for sleek results, while other covers may have textured surfaces or prongs for different effects. This allows high manufacturing precision to be applied only where needed rather than across the entire attachment.

Inventive Principle:

Principle #3Local quality

4Reliability

If current attachments use engagement teeth that do not extend throughout the entire engagement surface, then the manufacturing is easier, but the reliability of attachment connection is reduced

Engineering Contradiction:

Improvereliability of cover-to-base attachmentVSAvoidcomplexity of engagement feature fabrication

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The engagement features are segmented into discrete elements (teeth or ridges) distributed around the entire circumference of the base attachment. This segmentation provides reliable engagement at multiple points simultaneously, ensuring the cover stays securely attached while keeping each individual engagement feature simple to manufacture.

Inventive Principle:

Principle #1Segmentation

AI summary

An attachment assembly for an air-moving appliance includes a diffuser attachment and a hair engagement cover. The diffuser attachment includes an inlet end configured to removably attach to the air-moving appliance. The inlet end includes an inlet for airflow to enter the diffuser attachment and the outlet end includes a diffuser surface defining discharge openings for airflow in part to expel from the diffuser attachment. The diffuser surface is curved relative to an exterior of the diffuser attachment. The hair engagement cover includes prongs arranged to extend outward from the diffuser surface when the hair engagement cover is attached to the outlet end. The attachment assembly has a first configuration in which the hair engagement cover is not attached to the diffuser surface of the diffuser attachment, and a second configuration in which the hair engagement cover is attached to the outlet end of the diffuser attachment.
