Ball-Tip Detangling Comb for Tightly Curled Hair Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detangling and grooming tools are ineffective for tightly curled, deeply coiled hair, leading to discomfort and excessive hair breakage.
Innovation Solution
A comb with rigid teeth and enlarged ball-shaped beads that separate hair parallel to the scalp, providing better grip and reducing hair breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional combs with thin stiff bristles or teeth are used, then the tool structure is simple, but the detangling efficacy for tightly curled hair is poor and causes excessive hair breakage
Solution Approach 1:
The patent applies spheroidality by replacing conventional sharp or flat tooth tips with rounded ball-shaped tips having a diameter of 0.25 to 0.5 inches. This curvature allows the beads to gently separate and detangle tightly curled hair without causing breakage, as the rounded surface distributes force evenly and prevents snagging on delicate hair strands.
Solution Approach 2:
The patent changes the physical parameters of the comb teeth by enlarging the tip diameter to 0.25-0.5 inches (significantly larger than conventional teeth) and specifying a particular size range that is optimal for detangling. This parameter change transforms the interaction between the comb and hair, enabling effective separation of tightly curled locks without the harmful effects of conventional small, sharp teeth.
2Ease of operation
If conventional combs with thin stiff bristles are used, then the device complexity is low, but the grip on tightly curled hair is insufficient and fails to separate locks effectively
Solution Approach 1:
The rounded ball-shaped tips provide superior grip on tightly curled hair through their spherical geometry. The curved surface naturally conforms to the shape of curled hair locks, allowing the beads to penetrate and separate tangled sections effectively. This curvature-based design enhances operational ease without adding mechanical complexity.
Solution Approach 2:
The patent introduces a dimensional change by transitioning from thin, linear tooth structures to three-dimensional ball-shaped tips with significant diameter (0.25 to 0.5 inches). This dimensional expansion allows the comb to interact with hair in a new way, providing volumetric grip and separation capability that linear teeth cannot achieve, thereby improving ease of operation.

AI summary
A detangling tool. In the illustrative embodiment, the detangling tool comprises a rigid elongate spine having a longitudinal axis; plural rigid teeth extending from the spine along axes transverse to the longitudinal axis of the spine; and plural ball shape tips on the ends of the teeth, each tip being 3 to 4 times larger in diameter than the tooth upon which it is mounted. In various embodiments, the tool is implemented as a rake, a pick, and a comb. The inventive tool is designed to achieve a separation of hair, configured in locks or otherwise, in directions that are substantially parallel to the scalp. The enlarged ball shape tips effectuate a separation of the locks along axes parallel to the surface of the scalp of the individual being treated. In addition, the large ball shape tips of the tools of the present invention, are designed to maintain a better grip on the hair locked or unlocked as the comb is pulled therethrough in a downward direction through the hair compared to the teeth of conventional combs. That is, instead of merely pushing the hair down or sliding through the hair without much grip, the large, balled tips get under the hair, separate the locks of hair before being pulled downwardly and after the downstroke is initiated, the balls get under the locks and stay in place during the downward motion in a manner not typically observed or associated with conventional tools.
