Heated Hair Brush With Segmented Protrusions For Scalp Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heated hair brushes do not effectively enhance the absorption of topicals into the scalp, as they lack a mechanism to optimize temperature settings for improved skin permeability, which is crucial for hair and scalp health.
Innovation Solution
A heated hair brush design featuring heated and non-heated protrusions with a control unit and mechanism to adjust temperature and position, allowing for two modes: a high temperature mode for hair straightening and a lower temperature mode to enhance skin absorption by allowing direct contact between the non-heated protrusions and the scalp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heated brush uses high temperature (170-200°C) to straighten hair, then hair straightening effectiveness is improved, but skin safety is compromised due to risk of burns and excessive heat exposure
Solution Approach 1:
The brush head is segmented into two distinct carrier systems: a first carrier with heated protrusions for hair straightening and a second carrier with non-heated protrusions for scalp contact. This segmentation allows independent temperature control for each component, enabling high temperature for hair while keeping scalp-contacting elements at safe temperatures.
Solution Approach 2:
The non-heated protrusions on the second carrier act as intermediaries between the scalp and the heated elements. These protrusions can be positioned to contact the scalp directly without transferring excessive heat, while still allowing thermal energy from the heated protrusions to indirectly benefit the scalp through proximity and thermal field interaction.
2Adaptability or versatility
If the heated brush uses low temperature (40-50°C) to improve skin permeability for topical absorption, then topical absorption effectiveness is improved, but hair straightening capability is reduced
Solution Approach 1:
The brush system dynamically adjusts its configuration by moving the second carrier (with non-heated protrusions) relative to the first carrier. This dynamic positioning allows the user to select between different operational modes: close spacing for hair straightening and wider spacing for scalp treatment, enabling temperature-appropriate configuration for each function.
Solution Approach 2:
The brush is designed as a multi-functional device that can perform both hair straightening and scalp topical absorption enhancement. The universal brush structure incorporates both heated and non-heated protrusions that can be independently positioned, allowing a single device to serve multiple purposes with appropriate temperature control for each function.
3Object-affected harmful factors
If the non-heated protrusions extend beyond the heated protrusions to protect the scalp, then skin safety is improved, but the device complexity increases due to additional positioning mechanisms
Solution Approach 1:
The non-heated protrusions are pre-positioned on the second carrier at predetermined distances from the heated protrusions. This preliminary positioning allows the brush to automatically provide appropriate protection without requiring complex real-time adjustment mechanisms, simplifying the overall device while maintaining scalp safety.
4Adaptability or versatility
If the brush applies heat directly to the scalp to increase skin permeability, then topical absorption is improved, but the risk of skin damage increases due to prolonged high temperature exposure
Solution Approach 1:
The system changes the temperature parameter by using low temperature (40-50°C) for scalp treatment instead of high temperature. This parameter change enables prolonged exposure without causing skin damage, as the low temperature range promotes permeability enhancement while remaining within safe thermal limits for extended application periods.
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 dual-mode design improves topical absorption by increasing skin permeability, providing a safer and more effective spa-like experience with prolonged temperature application, enhancing scalp and hair health.
Implementation Method 1
heated protrusions... temperature of the heated protrusions exceeds 100°C
Implementation Method 2
the hot elements can directly touch the scalp so as to warm the skin to improve the permeability of the skin for the topical

AI summary
A heated hair brush (B) comprises heated protrusions (HP): non-heated protrusions (NHP); a control unit (C) arranged for controlling a temperature of the heated protrusions (HP); and a mechanism (FC. SC) arranged for controlling a position of the non- heated protrusions (NHP) relative to a position of the heated protrusions (HP). In a first mode (I). the non-heated protrusions (NHP) extend beyond the heated protrusions (HP), and the temperature of the heated protrusions (HP) exceeds 100° C. In a second mode (II). the non-heated protrusions (NHP) do not extend beyond the heated protrusions (HP), and the temperature of the heated protrusions (HP) does not exceed 50° C. The heated protrusions (HP) may be connected to a first carrier (FC), and the non-heated protrusions (NHP) may be connected to a second carrier (SC). In one embodiment, a distance (d) between the first and second carriers is modifiable. wherein in the first mode (I), the distance (d) is smaller than in the second mode (II). In another embodiment. the second carrier (SC) is laterally moveable with regard to the first carrier (FC), whereby in the first mode (I), the non-heated protrusions (NHP) are parallel to the heated protrusions (HP) whereby the non-heated protrusions (NHP) extend beyond the heated protrusions (HP), while in the second mode (II). the non-heated protrusions (NHP) are at an angle to the heated protrusions (HP) whereby the non-heated protrusions (NHP) do not extend beyond the heated protrusions (HP).
