Hair Styling Device With Wind Supply Assembly For Even Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional hair styling devices, such as curling irons, often cause skin burns and uneven heating, leading to suboptimal curling results and hair damage due to heat conduction from metal components.
Innovation Solution
A hair styling device with a housing containing a curling assembly featuring a heat-conducting cylindrical shell inside a top casing, a rotatable cylindrical shell, and a wind supply assembly that provides hot and cool air for even heating, along with a control assembly for safe and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heated metal bar with heat-conducting aluminum tube and springs is used for curling hair, then the device can achieve curly hair, but the skin of users could easily get burned during use
Solution Approach 1:
The patent introduces a wind supply assembly that blows hot air as an intermediary heating medium between the heating element and the hair. This replaces direct contact with heated metal components, eliminating skin burn risks while maintaining curling effectiveness through airborne heat transfer.
Solution Approach 2:
The patent replaces the mechanical heat conduction system (heated metal bar, aluminum tube, and springs) with a pneumatic system (wind supply assembly blowing hot air). This substitution eliminates direct skin contact with hot metal while achieving the same curling effect through hot air circulation.
2Temperature
If a heating element operating through heat conduction from the inside out is used, then the device can heat hair, but the innermost hair may easily be damaged due to high temperatures and the outer hair cannot easily be shaped
Solution Approach 1:
The patent inverts the traditional heating approach by using hot air blowing from the outside in instead of heat conduction from the inside out. The wind supply assembly directs hot air onto the outer surfaces of wound hair first, then progressively heats inner layers, preventing overheating of innermost hair while ensuring uniform curling of outer hair.
Solution Approach 2:
The patent employs a wind supply assembly with a fan and air channel to generate and direct hot air flow onto the hair. This pneumatic system provides uniform heat distribution across all hair surfaces regardless of their position, eliminating the temperature gradient problem of conventional heat conduction methods.
