Segmented Carrier Brush Bristles for Easier Tangle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair brushes struggle with effectively removing tangles due to neighboring bristles gathering at the tangle, making it difficult for the tangle to pass, and often cause discomfort due to bristle flexing and friction.
Innovation Solution
A brush design featuring a carrier that secures each bristle, allowing independent pivoting, with a frame and body configuration that isolates neighboring bristles from deformation, and uses hyperbolic paraboloidic bristle alignment for improved comfort and tangle handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cushion flexes to allow bristles to conform to the shape of the user's head, then comfort is improved, but neighbouring bristles gather at the tangle making it difficult to remove tangles
Solution Approach 1:
The cushion is divided into multiple independent flexible elements (individual carriers with bristles) rather than a continuous flexible mass. This segmentation allows each bristle to move independently when encountering a tangle, preventing the gathering effect that occurs with conventional continuous cushions, while still providing the conforming comfort benefit.
2Adaptability or versatility
If the carrier protrudes beyond each hole in the frame to achieve a larger range of motion, then bristle independence is improved, but friction and static generation increase
Solution Approach 1:
The protrusion distance of the carrier beyond each hole is optimized to a specific range (0.5-2mm). This parameter change allows sufficient carrier deformation for bristle independence while limiting excessive protrusion that would cause harmful friction and static generation in the hair.
3Ease of operation
If the carrier is held between the body and the frame at each bristle, then neighbouring bristles are isolated from deformation, but device complexity increases
Solution Approach 1:
The frame and body are merged into a single integrated component that incorporates the carrier holding function. The frame extends into the body and the carrier is held between the frame and body at each bristle location, combining structural support and bristle isolation functions into one element, thereby reducing overall device complexity.
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 design enables easier passage of tangles without neighboring bristles gathering, reduces discomfort, and enhances bristle penetration and alignment, improving the overall brushing experience.
Implementation Method 1
the carrier deforms in response to pivoting of each bristle
Implementation Method 2
Friction between the carrier and the hair may generate static within the hair

AI summary
A brush is described that includes a body, a carrier, a plurality of bristles and a frame. Each bristle is secured to the carrier and extends through a respective hole in the frame. The carrier deforms in response to pivoting of each bristle, and is held between the body and the frame at each bristle.
