Hair Styling Device with Segmented Heating and Forced Air Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multifunctional hair curlers are limited to single functions, either hair straightening or curling, and the process of curling hair is slow due to the need for heating a cylindrical tube to a certain temperature for an extended period.
Innovation Solution
A multifunctional hair straightening and curling device with upper and lower heating bodies connected by a rotary shaft, featuring air outlets and a fan to blow wind, allowing for simultaneous heating and cooling of hair, enabling faster curl setting by combining heating and air flow to instantly set hair curls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hair is wound on a heated aluminum tube or iron tube for curling, then the hair can be curled, but the setting speed of curly hair is very slow
Solution Approach 1:
The heating system is segmented into multiple independent heating bodies (first heating body, second heating body, third heating body) that can heat different sections of hair simultaneously. This parallel heating approach increases the overall curling speed and reduces the time required to set curls compared to traditional single-tube methods.
Solution Approach 2:
The patent combines heating function and cooling function into a single integrated device. The heating bodies heat the hair while the air outlet passages and fans provide simultaneous cooling to set the curls quickly. This merging of heating and cooling operations in one device achieves fast setting without requiring separate tools or extended time.
2Productivity
If a fan is added to blow wind for instant cooling and setting, then hair can be set quickly, but the device complexity increases
Solution Approach 1:
The main body structure serves multiple functions: it houses the heating bodies, contains the air outlet passages, and integrates the fan system. This multi-functional design achieves fast cooling and setting without proportionally increasing device complexity, as the same structural elements perform multiple roles in the hair styling process.
Solution Approach 2:
The air outlet passages are nested within the main body structure, and the fan is integrated into the housing. This nested arrangement allows the cooling system to be compact and efficient without adding significant external complexity to the device, maintaining a streamlined structure while achieving instant hair setting.
3Productivity
If multiple heating bodies are used to heat and soften hair simultaneously, then curling efficiency improves, but the device complexity increases
Solution Approach 1:
The heating bodies are designed to be movable relative to each other, allowing them to adjust their positions and orientations to accommodate different hair types and styling needs. This dynamic configuration enables multiple heating zones to work simultaneously on different sections of hair, improving curling efficiency while maintaining operational flexibility.
Solution Approach 2:
The patent arranges heating bodies in three-dimensional space with different orientations (first, second, and third heating bodies at various positions). This spatial dimensionality allows simultaneous heating of multiple hair sections from different angles, significantly improving curling efficiency without requiring a proportionally complex linear arrangement of components.
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
The device can both straighten and curl hair quickly, saving time by using wind to cool and set hair instantly, achieving a continuous curling effect and allowing for multiple styling options based on its speed.
Implementation Method 1
the fan is capable of blowing generated wind out from the first air outlets through the first air outlet passage, and the fan is capable of blowing the generated wind out from the second air outlets through the second air outlet passage. The hair is heated and softened by the upper heating body and the lower heating body, and is then curled on a cylindrical body combined by the upper main body and the lower main body and having the air outlets. Under the radiating action of wind, the hair is cooled and set instantly
Implementation Method 2
The hair is heated and softened by the upper heating body and the lower heating body
