Solution Overview

Problem

Conventional hair combs lack the ability to align and groom hair in a detailed and organized manner, often resulting in hair binding and tangling, and are ineffective in removing unwanted debris such as dirt and lice.

Innovation Solution

The development of multi-axis alignment tines with unique geometry and spacing, featuring convex and concave surfaces arranged in an offset configuration, allowing for primary and secondary hair alignment and effective debris removal when used in an array on a hair comb.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional singular line tines are used, then the comb structure is simple, but the hair alignment capability is insufficient and causes tangling

Engineering Contradiction:
Improvehair alignment capabilityVSAvoidtine structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The comb tines are segmented into multiple functional surfaces including convex surfaces, concave surfaces, and offset surfaces. Each surface performs a specific alignment function, dividing the complex alignment task into manageable segments that work together to reduce tangling and improve grooming capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from conventional two-dimensional tine arrangements to a three-dimensional multi-axis configuration. The tines incorporate convex surfaces protruding in one direction, concave surfaces in another direction, and offset surfaces creating multiple alignment axes, enabling hair to be aligned from multiple directions simultaneously

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If conventional tines are used, then the comb design is simple, but debris removal effectiveness is poor

Engineering Contradiction:
Improvedebris removal effectivenessVSAvoidtine geometry complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Different portions of the comb tines are given different geometric properties to perform specialized functions. Convex surfaces are optimized for one type of debris interaction, concave surfaces for another, and offset surfaces for specific alignment tasks, allowing each local region to excel at its particular function for comprehensive debris removal

Inventive Principle:
Principle #3Local quality
