Solution Overview

Problem

Existing hairdressing devices, such as blowing hairbrushes, are complex, difficult to use, and lack ergonomic design, making it hard for users without styling expertise to achieve satisfactory drying and styling results, often requiring additional devices for comprehensive hair management.

Innovation Solution

A portable hairdressing device with a blower module, manual handle, and accessory featuring distinct air outlets and a rotating mechanism for variable angular orientation, allowing for efficient air distribution and mechanical hair engagement, enabling users to perform multiple styling operations without external devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If blow-dry hairbrushes combine brushing and drying functions, then device versatility is improved, but device complexity increases

Engineering Contradiction:

Improvedevice versatilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the blowing function and brushing function into a single integrated device. The blower module generates airflow that is directed through the brush head, allowing simultaneous drying and styling. The housing integrates both the motor housing for the blower and the brush bristles, creating a unified tool that performs multiple functions without requiring separate devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device is designed to perform multiple hair styling functions including drying, brushing, and shaping. The adjustable airflow direction and the mechanical brush engagement allow the single device to replace multiple specialized tools, providing universal applicability for various hair styling needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If blow-dry hairbrushes have complex design, then device functionality is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvedevice functionalityVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The device automatically adjusts airflow distribution based on the mechanical engagement with hair. The brush bristles mechanically engage the hair and guide it through the airflow path, eliminating the need for users to manually control airflow direction or adjust settings. The device self-regulates to provide optimal drying and styling based on the hair's position and movement.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If blow-dry hairbrushes lack compactness, then device functionality is improved, but ergonomics deteriorates

Engineering Contradiction:

Improvedevice functionalityVSAvoidergonomics

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The blower module is nested within the brush head housing. The motor housing contains the blower mechanism, and the brush bristles are integrated into the same housing structure. This nested arrangement allows the functional components to be compactly arranged, reducing the overall device size while maintaining both blowing and brushing capabilities.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Adaptability or versatility

If blow-dry hairbrushes require additional devices, then comprehensive hair management is achieved, but device complexity increases

Engineering Contradiction:

Improvecomprehensive hair managementVSAvoidsystem complexity

Core Design Contradiction:
