Solution Overview

Problem

Existing hair straighteners require the use of a separate hair dryer for blow-drying and straightening, limiting their functionality.

Innovation Solution

A heating and blowing hair straightener with integrated heating plates and a fan module that allows for simultaneous heating and blow-drying, featuring a design with combing structures and a puff port for efficient air flow management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional straightener with only heating plates is used, then the structure is simple, but the functionality is limited and requires a separate hair dryer

Engineering Contradiction:
ImprovefunctionalityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines a hair dryer and a straightener into a single integrated device. The hair dryer component includes a fan module, air inlet, and air outlet that are merged with the straightener's heating plates and clamping structure, allowing both blow-drying and straightening functions in one device

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated device performs multiple functions: it can blow-dry hair using the fan module and air flow path, and it can straighten hair using the heating plates and clamping mechanism. This multi-functional design eliminates the need for separate hair dryer and straightener devices

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If a separate hair dryer and straightener are used, then each device can be optimized for its specific function, but the overall process requires multiple steps and more time

Engineering Contradiction:
ImproveefficiencyVSAvoidtime
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

By merging the hair dryer and straightener into one device, the patent enables simultaneous or sequential operation of both functions without the need to switch between separate devices, thereby reducing the total time required for hair styling

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated design allows the user to perform blow-drying and straightening in a single continuous process rather than as separate sequential steps, eliminating the time loss associated with transitioning between devices

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the fan module is added to create an air-draught gap for blow-drying, then the functionality is improved, but the device complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fan module is integrated within the existing straightener structure, sharing the same housing and operational mechanism. The air inlet and air outlet are incorporated into the existing clamping structure, merging the blow-drying function with the straightening mechanism rather than adding a completely separate device

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables hair to be heated and straightened without the need for a separate hair dryer, improving efficiency and reducing noise through capacitive air guiding and shockproof design.

AI summary

The present application relates to a heating and blowing hair straightener, belonging to a field of hair styling appliances, including a first splint and a second splint, a tail end of the first splint and a tail end of the second splint are rotatably connected with each other. A front end of the first splint has a first straightening part, the second splint has a second straightening part corresponding to the first straightening part. The first straightening part is provided with a first heating plate on an upper part at an inner side thereof, the second straightening part is provided with a second heating plate in cooperation with the first heating plate on an upper part at an inner side thereof. When the first heating plate abuts against the second heating plate, an air-draught gap is formed between the first straightening part and the second straightening part, the first splint has an installation space and a fan module is installed inside the installation space, the tail end of the first splint has an air inlet in communication with the installation space, and the inner side of the first straightening part is provided with an puff port in communication with the installation space. The present application improves a situation where a straightener has single function and needs to be used in conjunction with a hair dryer.
