Frustoconical Curling Mandrel for Faster, Lower-Loss Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair curling devices are energy-inefficient and slow in achieving optimal curling temperatures, while also suffering from significant heat loss due to exposure to ambient air.
Innovation Solution
A hair styling accessory featuring a frustoconical mandrel with an internal deflector and an annular slot, which directs internal air flow radially through outlet orifices and generates an external protective air knife, enhancing temperature distribution and reducing heat loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional hair curling accessories are used, then curling function is provided, but energy consumption is high and heat loss is significant
Solution Approach 1:
An annular slot is introduced as an intermediary structure that generates a protective air knife between the mandrel and ambient air. This air knife acts as a thermal barrier, reducing heat loss from the mandrel while maintaining the operating temperature necessary for curling hair effectively.
2Temperature
If traditional accessories are used, then curling is achieved, but temperature is reached slowly
Solution Approach 1:
The conical deflector with obstacles is positioned in advance within the mandrel to preemptively deflect internal air flow radially toward the orifices. This preliminary arrangement ensures that when air flow is generated, it is immediately directed toward the heating zones, accelerating the temperature rise speed without requiring additional time for heat distribution.
3Use of energy by moving object
If air flow is distributed uniformly, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The conical deflector is segmented with multiple obstacles (shoulders, protuberances, spiral stairs) arranged along its surface. Each obstacle acts as an independent flow deflection element, collectively achieving uniform air flow distribution through the orifices. This segmentation allows complex flow control to be achieved through simple, modular structural elements without significantly increasing manufacturing complexity.
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 accessory achieves rapid temperature rise and uniform airflow distribution, resulting in energy savings and improved curl formation with enhanced volume at the base of the locks.
Implementation Method 1
an external air flow acts as a protective air knife around the hair styling mandrel, and makes it possible to limit the heat loss from the accessory
Implementation Method 2
the deflector has an overall frustoconical shape and includes structural obstacles on the surface thereof making it possible to deflect an internal air flow radially toward the orifices of the mandrel
Implementation Method 3
a blowing and heating device comprising: a cylindrical connector; a frustoconical mandrel comprising a distal side and a proximal side

AI summary
A hair styling accessory for attachment to a blowing and heating device may include a cylindrical connector and a frustoconical-shaped mandrel, having a distal end and a proximal end, the distal end having a greater diameter than the proximal end, the proximal end being connected to the cylindrical connector. The mandrel has a plurality of air outlet ports. A frustoconical-shaped baffle is located within the mandrel. The cylindrical connector has an annular slot enabling the creation, when in use, of a protective layer of hot air around the mandrel.
