Multi-Row Claw Clip Teeth for Fine Hair Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair clips with a single row of teeth tend to slide out of place when holding fine or thin hair, especially during vigorous movements.
Innovation Solution
A hair clip design featuring multiple rows of teeth, including a first and second row that interleave and are secured by a spring mechanism, with optional third rows for enhanced grip, allowing secure engagement and retention of hair through various movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single row of teeth is used in conventional clips, then the clip structure is simple and easy to manufacture, but the clip tends to slide out of place when holding fine or thin hair during vigorous movement
Solution Approach 1:
The tooth structure is segmented into multiple rows (first row and second row) with different configurations. The first row extends laterally inward at an intermediate location, while the second row extends at or near the bottom. This segmentation allows each row to engage different portions of hair, improving overall grip stability without requiring a completely redesigned clip structure.
Solution Approach 2:
The patent transitions from a single-row (two-dimensional) tooth arrangement to a multi-row (three-dimensional) configuration. By adding teeth at different vertical positions (intermediate location and bottom), the clip creates engagement points across multiple dimensions, enhancing its ability to hold fine hair securely during movement.
2Ease of manufacture
If all teeth have the same length in conventional clips, then manufacturing is simplified, but the clip cannot effectively engage both central and bottom portions of gathered hair
Solution Approach 1:
Different rows of teeth are designed with different characteristics suited to their specific functions. The first row teeth extend to an intermediate location to engage central hair portions, while the second row teeth extend to the bottom to engage lower hair portions. This local differentiation optimizes hair engagement at each location while maintaining overall manufacturability.
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 multi-row design effectively secures fine or thin hair by interleaving teeth, providing stability and preventing slippage even during physical activity.
Implementation Method 1
The spring may force the first side and second side together, or into their closed arrangement
Implementation Method 2
tops of the first side and second side may be joined by way of hinge that enables portions of the first side and second side to be pivotally moved between a closed arrangement

AI summary
A hair clip includes a first side and a second side that are connected to each other with a hinge. Each side of the clip includes two or more rows of teeth, imparting the clip with at least two rows of teeth, including an outer row at or near a bottom of the clip and an intermediate row closer to a top of the clip. As the sides of the clip close together, corresponding rows of teeth on the two sides of the clip may face, or oppose, each other. Teeth of the opposed rows may mesh, or interleave with each other. Methods for using clips with multiple rows of teeth are also disclosed.
