Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair heat treatment devices, such as hot combs and brushes, face limitations in safety and operational efficiency due to the lack of effective spacing between heating elements and the scalp, which can lead to scalp injuries and uneven heating.
Innovation Solution
A hairbrush design featuring self-adjustable and heat-insulating spacers that maintain a specified distance between heating elements and the scalp, ensuring safety and efficient heat distribution through axial displacement and a patterned arrangement of heating elements for three-dimensional hair treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heating elements are placed close to the scalp for effective heat treatment, then heat treatment efficiency is improved, but scalp safety deteriorates due to risk of contact and injury
Solution Approach 1:
The patent introduces spacers as intermediary elements positioned between the heating elements and the scalp. These spacers maintain a safe distance while allowing heat to be effectively transmitted to the hair, thus mediating between the conflicting requirements of close proximity for efficiency and distance for safety
Solution Approach 2:
The patent moves the spacing function from a two-dimensional plane to a three-dimensional space by introducing spacers that extend perpendicular to the brush surface. This creates a vertical dimension of safety clearance while maintaining horizontal coverage for effective heat treatment
2Manufacturing precision
If spacers are made rigid to maintain consistent distance, then spacing precision is improved, but adaptability to different scalp contours deteriorates
Solution Approach 1:
The patent changes the physical state parameter of the spacers from rigid to flexible, allowing them to maintain their dimensional precision while adapting their shape to conform to different scalp contours through elastic deformation
Solution Approach 2:
The patent employs flexible spacer materials that can bend and conform to the scalp's surface geometry while maintaining their thickness and spacing function, effectively using flexible elements to solve both precision and adaptability requirements
3Stability of the object's composition
If heating elements are dispersed at high density for uniform heat distribution, then heat uniformity is improved, but device complexity increases
Solution Approach 1:
The patent divides the heating system into multiple discrete heating elements distributed across the brush surface, with corresponding spacers for each element. This segmentation allows for systematic arrangement that achieves uniform heat distribution while maintaining manageable structural complexity through modular design
