Hair Styler Heating and Pressing Paths to Reduce Hair Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair styling devices, such as straighteners and crimpers, cause long-lasting damage to hair due to the combination of high heat, pressure, and stretching, which are necessary for achieving a long-lasting style.
Innovation Solution
A hair styling device with corrugated heating panels that heat the hair without pressing it, followed by planar pressing panels that apply pressure separately, reducing the duration and intensity of heat and pressure application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high heat and pressure are applied simultaneously to hair between heating panels, then long-lasting styling is achieved, but hair damage increases due to the combined effects of heat, pressure, and stretching
Solution Approach 1:
The device divides the styling function into two separate components: corrugated heating panels for heat application and planar pressing panels for pressure application. This segmentation allows heat and pressure to be applied at different stages and with different intensities, reducing the cumulative damage while maintaining styling effectiveness.
Solution Approach 2:
The corrugated heating panels first heat the hair before it passes between the planar pressing panels. This preliminary heating action prepares the hair for styling without requiring simultaneous high-intensity pressure, thereby reducing damage while achieving the desired long-lasting effect.
2Reliability
If the heating panels are made wider to provide sufficient heating area, then effective styling is achieved, but the device width increases making it less aesthetically pleasing
Solution Approach 1:
The corrugated heating panels utilize the third dimension (depth/height) by creating a corrugated profile that increases the effective heating path length without increasing the panel width. This allows sufficient heating area and contact time while maintaining a compact device width for aesthetic appeal.

Function Achieved in This Case
Reduces hair damage by minimizing the time and intensity of heat and pressure application, while maintaining effective styling performance.
Implementation Method 1
the first and second heating panels being corrugated and adapted to heat a length of hair as the length of hair moves therebetween
Implementation Method 2
heat a length of hair as the length of hair moves therebetween
Implementation Method 3
the first and second pressing panels being substantially planar and being closer together than the heating panels in the operative condition

AI summary
A hair styling device is described, having first and second members that are movable relative to one another between a closed operative condition and an open inoperative condition. The first member has a first heating panel and the second member has a second heating panel, the heating panels being adapted to heat a length of hair as the length of hair moves along a heating path therebetween in use, and being spaced apart in the operative condition to avoid pressing or clamping the hair therebetween. The first member also has a first pressing panel and the second member has a second pressing panel. The pressing panels are substantially planar. The length of hair moves along a pressing path between the first and second pressing panels in use. The length of the heating path is greater than the length of the pressing path.
