Hair Brush with Hollow Bulb Guide for Heat-Shaped Curls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for hair brushes optimized for shaping hair into specific styles, as existing hair brushes do not effectively create diverse wave or curl shapes using hot air styling tools.
Innovation Solution
A hair brush design featuring a handle and a brush head with a hair-shaping guide and bristles, where the hair-shaping guide is a hollow shell with interconnected bulbs and necks that engage hair, allowing for the creation of desired wave or curl shapes when heated with a blow dryer, maintaining the style after unwrapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional hair brushes are used, then basic hair brushing function is achieved, but the ability to shape hair into specific styles with diverse wave or curl shapes is insufficient
Solution Approach 1:
The brush head is divided into multiple independent heating zones corresponding to different bulb regions, each capable of being heated separately to create different curl patterns in different sections of hair simultaneously
Solution Approach 2:
Different regions of the brush head (bulbs and necks) have different heating characteristics and shapes, allowing each region to create specific local styling effects - bulbs create curls while necks create waves, enabling diverse styling capabilities from a single brush head
2Adaptability or versatility
If a simple brush head design is used, then manufacturing is easier, but the ability to create diverse wave or curl shapes is limited
Solution Approach 1:
The hollow shell structure contains multiple nested bulb and neck regions within a single guide component, allowing complex styling capabilities to be achieved through a unified manufacturing process rather than assembling multiple separate components
Solution Approach 2:
The manufacturing process allows for variation of geometric parameters (bulb size, neck length, curvature) to create different curl patterns, enabling diverse styling capabilities without changing the fundamental manufacturing approach
3Reliability
If hot air styling is applied to hair wrapped around the brush, then hair shaping is achieved, but the style may not be maintained after removing the hair from the brush head
Solution Approach 1:
The brush head pre-shapes the hair around its contours before heat application, so that when heat sets the style, the hair already has the desired form, making the style more likely to hold after removal
Solution Approach 2:
The heating process utilizes thermal energy to transition hair from a pliable state to a set state, where the hydrogen bonds in keratin are temporarily broken and then reformed in the new shape, locking in the style
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 hair brush effectively shapes hair into various wave or curl forms by utilizing the unique shape of the hair-shaping guide and bristles, ensuring the style is maintained even after removing the hair from the brush head, offering versatility in curl tightness and shape.
Implementation Method 1
a brush head to brush and shape the hair of the person
Implementation Method 2
applying heat by directing hot air from a blow dryer on the plurality of hairs and the brush head
