Musical Comb With Variable Depth Base For Even Combing And Note Playback

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing personal grooming devices, such as combs, that attempt to combine grooming functions with music relay often suffer from uneven tooth spacing and height variations, leading to inefficient hair combing due to displacement or extreme height differences between teeth, which disrupt even passage through hair.

Innovation Solution

A personal grooming device with a body featuring groups of collinear teeth extending from a variable depth base, where each group corresponds to a specific musical note, with gaps between groups allowing for distinct note separation and varying lengths of teeth determining frequencies, enabling effective combing and music playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If teeth are separately attached to the handle to allow displacement while combing or playing music, then the device enables music playback functionality, but the teeth displacement causes uneven combing and disrupted passage through hair

Engineering Contradiction:

Improvemusic playback functionalityVSAvoidcombing function

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The comb is divided into functional segments: a stable base portion and a tooth portion with specific spacing arrangements. The teeth are organized in groups with different spacing patterns (equal spacing in some groups, unequal spacing in others) to simultaneously enable music playback and maintain combing functionality without displacement issues

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the comb have different tooth spacing characteristics. Some tooth groups have equal spacing for combing, while others have unequal spacing for music playback. This local differentiation allows each region to optimize for its specific function while the whole device maintains both functionalities

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If teeth are calibrated to certain depth within the comb, then the device enables music note differentiation, but extreme height differences between neighboring teeth prevent even passage through hair

Engineering Contradiction:

Improvemusical note differentiationVSAvoideven passage through hair

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The teeth are segmented into different groups with different depth calibrations. Each group corresponds to different musical notes, while maintaining overall collinearity of tooth ends to ensure even combing passage

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base has an asymmetric contour with variable depth, allowing teeth at different positions to extend to different depths from the base surface. This asymmetric base design enables musical note differentiation while the tooth ends remain collinear for smooth combing

Inventive Principle:

Principle #4Asymmetry

3Volume of moving object

If the base is sharply inclined, then the device enables compact structure, but the teeth become substantially smaller in size at one end than another, resulting in uneven combing

Engineering Contradiction:

Improvecompact structureVSAvoideven combing

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The base features a curved, contoured surface rather than a sharp inclination. This curved base allows teeth to be positioned at varying depths while maintaining uniform tooth height and collinearity, ensuring even combing across the entire comb structure

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A personal grooming device a body defining a grasping surface defining an outer portion and an inner portion, as well as groups of members extending directly from the inner portion at varying depth so that the members are capable of playing a musical note or notes.
