Switchable Air Roll for Left-Right Hair Styling

Solution Overview

Problem

Existing hair care appliances require separate left and right air discharge attachments for styling hair on both sides, necessitating frequent detachment and reattachment, which complicates the styling process.

Innovation Solution

An air roll for a hair care appliance featuring a direction switching mechanism that allows air discharge direction to be switched between left and right using a rotation handle, incorporating pairs of left and right air discharge holes and a direction adjusting part to manage both sides with a single device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate left and right air discharge attachments are used, then hair styling on both sides is achieved, but frequent detachment and reattachment is required

Engineering Contradiction:

Improvehair styling capabilityVSAvoidattachment changing frequency

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The air roll attachment is designed with a universal structure that can perform both left and right hair styling functions. The main body includes multiple air discharge holes positioned at different locations, allowing a single attachment to serve multiple styling purposes without requiring separate left and right attachments.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The attachment incorporates a rotatable direction switching part that allows dynamic adjustment of air discharge direction. By rotating this part, the user can switch between discharging air to the left and right sides, enabling the same attachment to adapt to different styling needs throughout the hair care process.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a single air roll is used for both sides, then attachment changing is reduced, but air discharge direction control is limited

Engineering Contradiction:

Improveattachment changing frequencyVSAvoidair discharge direction control

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The attachment incorporates a rotatable direction switching part that allows dynamic adjustment of air discharge direction. By rotating this part, the user can switch between discharging air to the left and right sides, enabling the same attachment to adapt to different styling needs throughout the hair care process.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The air roll is divided into multiple functional segments with separate air discharge holes positioned at different locations around the main body. This segmentation allows independent control of air discharge to different sides through the direction switching mechanism, providing precise directional control while maintaining a single unified attachment structure.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If air is discharged in a fixed direction, then device structure is simple, but hair care on both sides requires multiple attachments

Engineering Contradiction:

Improveattachment structureVSAvoidhair care coverage

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The air roll attachment is designed with a universal structure that can perform both left and right hair styling functions. The main body includes multiple air discharge holes positioned at different locations, allowing a single attachment to serve multiple styling purposes without requiring separate left and right attachments.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The attachment incorporates a rotatable direction switching part that allows dynamic adjustment of air discharge direction. By rotating this part, the user can switch between discharging air to the left and right sides, enabling the same attachment to adapt to different styling needs throughout the hair care process.

AI summary

The present disclosure relates to an air roll for a hair care appliance capable of switching a discharge direction of air to a left direction or a right direction using a single device and managing the hair at the left and right sides with one air roll.According to an air roll for a hair care appliance of the present disclosure, a direction adjusting part opens and closes left air discharge holes or right air discharge holes with a rotation of a direction switching part to switch a discharge direction of air to a left direction or a right direction. This makes it possible to manage the left hair and the right hair with a single air roll mounted to the hair care appliance without having to alternately mount a left-side device and a right-side device to the hair care appliance as in the related art, thus improving the usability at a low cost.
