Heatable Headform for Scalp Temperature Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair mannequins lack the necessary heat to accurately simulate hair color processing and chemical processes, leading to over-processing and damage such as 'hot roots' and brittle hair when used by stylists and technicians.
Innovation Solution
A thermographically appropriate system comprising a heatable headform and a replaceable human hair covering made of heat-conductive material, heated to approximately 98-99 degrees Fahrenheit to simulate the human scalp temperature, allowing for accurate hair color and chemical processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional hair mannequin at room temperature is used, then the structure is simple and easy to manufacture, but the temperature is insufficient to accurately simulate hair color processing and chemical processes
Solution Approach 1:
The mannequin is divided into separate functional components: a heatable headform (separate heating element) and a hair covering. This segmentation allows the headform to be heated independently to simulate scalp temperature while keeping the hair covering simple and replaceable.
Solution Approach 2:
The headform serves multiple functions: it provides structural support for the hair, acts as a heat source to simulate human scalp temperature, and enables accurate chemical processing simulation. This multi-functionality resolves the contradiction by adding heating capability without proportionally increasing overall complexity.
2Reliability
If a heatable headform with replaceable hair covering is used, then accurate temperature simulation is achieved, but the device complexity increases
Solution Approach 1:
Heating is applied locally to the headform rather than uniformly throughout the entire mannequin. The heating elements are concentrated in the headform structure, providing targeted temperature control where it is needed for simulating scalp conditions during chemical processing.
Solution Approach 2:
The system changes the temperature parameter of the headform to match human scalp temperature (approximately 98.6°F or 37°C). This parameter change enables reliable simulation of chemical processing conditions while the modular design keeps the increase in complexity manageable.
3Object-affected harmful factors
If room temperature mannequin is used, then the device is simple to operate, but hair damage occurs due to over-processing
Solution Approach 1:
The headform is pre-heated to simulate human scalp temperature before chemical processing begins. This preliminary heating action ensures that the chemical processes occur at the correct temperature from the start, preventing over-processing and hair damage without requiring complex real-time temperature adjustments during the procedure.
