Hair Styling Device Rotary Winder and Temperature Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair styling devices often cause hair to slip during curling, leading to uncomfortable pulling and uneven heat distribution, with a risk of overheating and handling difficulties due to inadequate design and lack of protective measures.
Innovation Solution
A styling device with a rotary hair winder and temperature sensor for overheating protection, shifting the center of gravity to the handle for improved handling, and eliminating the need for hair clips by using arms to wrap hair evenly around the work surface, ensuring complete coverage and even heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hair clamp is used to fix hair to the working surface, then the hair can be held in place during curling, but the hair may slip between the working area and clamp causing pulling, and part of the hair wraps around the clamp preventing optimal heat distribution
Solution Approach 1:
The patent removes the hair clamp component entirely from the styling device. Instead of using a clamp to hold hair, the device uses a heated cylindrical working surface that automatically winds and holds hair through its geometry and heat adhesion, eliminating the problems of hair slipping and clamping interference with heat distribution
Solution Approach 2:
Rather than using a mechanical clamp to grip hair from the outside, the invention inverts the approach by using the heated working surface itself to capture and hold hair through thermal adhesion and cylindrical geometry, allowing hair to be wrapped around the curve rather than clamped linearly
2Ease of operation
If the center of gravity is positioned in the traditional location, then the device structure is balanced, but the tool does not rest comfortably in the palm and may pose fire risk when set down
Solution Approach 1:
The patent shifts the center of gravity toward the handle end of the device, creating a counterbalancing effect that allows the weighted handle to rest comfortably in the palm. This weight distribution also ensures that when the device is set down, the heavier handle end contacts the surface first, positioning the heated working surface away from flammable surfaces and reducing fire risk
3Productivity
If the work surface is heated to high temperatures for effective curling, then hair styling efficiency is improved, but damage to hair or scalp may occur and fire damage risk increases
Solution Approach 1:
The patent incorporates a temperature sensor that continuously monitors the heating element temperature and provides feedback control. When the sensor detects that the maximum temperature is reached, it automatically interrupts the heating process, preventing overheating damage to hair or scalp while maintaining effective styling temperatures during normal operation
Solution Approach 2:
The temperature sensor and automatic interruption system serve as a protective measure in advance, cushioning against the potential harmful effects of overheating before they can occur. The system is pre-configured to interrupt heating at the safe temperature threshold, preventing damage rather than reacting to it after it occurs
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
Facilitates easy and efficient hair styling with even heat distribution, preventing damage from overheating and improving handling safety by ensuring the entire strand is heated uniformly and reducing the risk of fires.
Implementation Method 1
the work surface is provided with overheat protection in the form of a temperature sensor which interrupts the heating process independently of the operating elements when a certain temperature is reached
Implementation Method 2
a winding device for the hair, wherein the winding device consists of a hair winder which consists of a rotatably driven rotating body with arms extending in the axial direction to the working surface
Implementation Method 3
a heated working surface around which strands of hair are wrapped, creating a curl structure through the application of heat

AI summary
The invention relates to a styling device 1 for hair, comprising at least a handle 2, a cylindrical work surface 3 for winding the hair, and a winding device 4 for the hair. To facilitate winding the hair onto the work surface 3 and to prevent unpleasant hair pulling, the winding device 4 consists of a hair winder 5, which comprises a rotatably driven rotating body 6 with axially extending arms 7. The arms 7 grasp the hair strands and wind them around the work surface 3, thus facilitating the winding process.
