Pivotable Comb Teeth for Hair Curler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair curlers with fixed comb teeth can cause discomfort and inconvenience due to hair getting stuck or snapped during use, leading to reduced user comfort and effectiveness.
Innovation Solution
A hair curler design featuring pivotable comb teeth that are movable relative to the curling iron assembly, allowing for sliding or pivotal movement within recesses and grooves, which mitigates hair snapping and enhances the hair curling process by providing flexibility and guiding the hair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed comb teeth are used on the curling iron, then the structure is simple and manufacturing is easy, but hair may get stuck or snapped during use, reducing user comfort
Solution Approach 1:
The comb teeth are designed to be pivotable rather than fixed, allowing them to move dynamically during hair curling. Each comb tooth can pivot independently within its recess to adapt to hair thickness and tension, preventing hair from getting stuck or snapped while maintaining structural simplicity.
2Reliability
If pivotable comb teeth are implemented, then hair snapping is reduced and user comfort is improved, but the device structure becomes more complex
Solution Approach 1:
The comb tooth assembly is segmented into multiple independent pivotable teeth, each capable of moving separately within its own recess. This segmentation allows each tooth to independently adapt to hair conditions without affecting other teeth, reducing hair damage while keeping the overall structure manageable through modular design.
Solution Approach 2:
The comb teeth change their positional parameter by pivoting within recesses of the curling iron body. This parameter change allows the teeth to adjust their angle and position dynamically, preventing hair from being pulled or snapped while maintaining a relatively simple structural implementation.
3Adaptability or versatility
If comb teeth are made movable within recesses, then hair guiding flexibility is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The recesses are designed with specific local geometric characteristics that guide the pivotable teeth's movement. By optimizing the local shape and dimensions of the recesses, the design achieves adequate guidance flexibility for various hair types while maintaining manufacturability and avoiding excessive precision requirements.

AI summary
A hair curler includes a curling iron assembly and comb tooth assembly arranged on the curling iron assembly. The curling iron assembly includes a heating body (12) and a metal sleeve (11) disposed around the heating body (12), the metal sleeve (11) having a linear groove (111) formed in an outer surface of the metal sleeve (11). The comb tooth assembly includes a comb tooth bar (21) disposed within the linear groove (111), a recess (211) formed between a bottom wall of the linear groove and an interior portion of the comb tooth bar (21), and a plurality of pivotal comb teeth (22) having an inserted portion (221) pivotally retained within the recess (211), wherein the pivotal comb teeth (22) are movable relative to the comb tooth bar (21).
