Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair styling devices are inefficient in creating volume at the roots of hair, often requiring close proximity to the scalp, which can lead to burning and inadequate heat transfer, and lack effective mechanisms for rapid heating and cooling.
Innovation Solution
A hair styling apparatus featuring a heating member with a comb-like structure, a cooling member, thermal insulation, and tensioning members that project from the heating member to grip and style hair, while a guard prevents scalp burns and an active cooling mechanism ensures efficient temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing hair styling devices are used to create volume at the roots, then hair volume can be achieved, but the devices require close proximity to the scalp which causes burning risk and inadequate heat transfer
Solution Approach 1:
The device segments the styling function into distinct heating and cooling zones with physical separation. The heating element and cooling element are positioned as separate components with insulation between them, allowing independent optimization of each zone's temperature and function while preventing harmful heat transfer to the scalp.
Solution Approach 2:
Thermal insulation material is introduced as an intermediary between the heating element and cooling element. This intermediary prevents harmful heat transfer from the heating zone to the cooling zone and to the scalp, while still allowing the heating element to effectively heat the hair.
2Productivity
If existing hair styling devices heat hair at the roots, then volume can be created, but the heating efficiency is poor and the process is time-consuming
Solution Approach 1:
The device merges heating and cooling functions into a single integrated apparatus that can simultaneously perform both operations on different sections of hair. The tensioning members ensure consistent hair contact with both heating and cooling zones, improving overall styling efficiency and reducing processing time.
Solution Approach 2:
The tensioning members pre-position and secure the hair in optimal contact with the heating element before heating begins. This preliminary positioning ensures maximum heat transfer efficiency from the start of the heating process, reducing the time required to achieve the desired styling effect.
3Object-affected harmful factors
If a guard is added to prevent scalp burns, then safety is improved, but the device complexity increases
Solution Approach 1:
The cooling element serves multiple functions: it cools the hair to set the style, prevents scalp burning by maintaining a cool temperature zone near the scalp, and provides structural support for the guard. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

AI summary
The application describes hair styling apparatus (1) for creating volume in a user's hair. The hair styling apparatus (1) comprises a heating member, a cooling member adjacent to the heating member, thermal insulation between the cooling member and the heating member and a tensioning member projecting from the heating member. The heating member comprises a heating contacting surface for heating hair in contact with the heating member. The cooling member has a cooling contacting surface for cooling hair in contact with the cooling member and the cooling member is cooled by an active cooling mechanism. The tensioning member tensions a user's hair against the heating contacting surface to improve heat transfer into a user's hair and applies stress to a user's hair as the hair contacts the cooling contacting surface adjacent the heating contacting surface whereby the hair is styled to create volume.
