Solution Overview

Problem

Existing straight hair combs with fixed heat-insulating comb covers face issues with hygiene maintenance due to dirt and broken hair accumulation, difficulty in cleaning, and safety risks from direct contact with high-temperature components.

Innovation Solution

A detachable heat-insulating comb cover design with magnetic, clamping, and positioning mechanisms allows easy removal and replacement, featuring metal and plastic comb teeth with adjustable gaps and insulation properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed heat-insulating comb cover is used, then the structure is simple and stable, but the comb cover cannot be removed for cleaning and dirt accumulates in the gap

Engineering Contradiction:

ImprovecleanabilityVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The comb cover is designed as a detachable component that can be separated from the heating comb head, allowing the cover to be removed for cleaning. This segmentation resolves the contradiction by enabling cleanability while maintaining a relatively simple overall structure through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The comb cover transitions from a fixed static structure to a dynamic detachable structure, allowing it to be removed when cleaning is needed and reattached during use. This dynamic design enables the comb cover to adapt between cleaning and usage states.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the gap between the heat-insulating comb cover and heating comb head is small, then the appearance is compact, but dirt and broken hair cannot be cleaned

Engineering Contradiction:

ImprovecleanabilityVSAvoidgap size

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

By segmenting the comb cover into a detachable component, the cleaning problem is resolved without needing to increase the gap size. The cover can be completely removed for thorough cleaning, maintaining a compact appearance when assembled while enabling complete cleanability.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If a detachable comb cover is used, then the comb can be cleaned easily, but the connection structure becomes more complex

Engineering Contradiction:

ImprovecleanabilityVSAvoidconnection structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The magnetic connection replaces complex mechanical fastening systems with a simpler magnetic field-based connection. This allows the comb cover to be detachable for cleaning while using an elegant and relatively simple magnetic connection structure rather than screws, clips, or other mechanical fasteners.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Temperature

If metal comb teeth directly contact the heating comb head, then heat conduction is efficient, but burn risks increase

Engineering Contradiction:

Improveheat conduction efficiencyVSAvoidburn risk

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The heat-insulating comb cover serves as an intermediary layer between the heating comb head and the user's hair/scalp. It allows efficient heat conduction to straighten hair while preventing direct contact between high-temperature components and the user, thereby reducing burn risks.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The comb cover provides localized thermal insulation where needed - between the heating element and the user - while allowing heat conduction at the metal comb teeth contact points with hair. This local differentiation of thermal properties resolves the contradiction between heat conduction efficiency and burn prevention.

Inventive Principle:

Principle #3Local quality

AI summary

A straight hair comb with a detachable and heat-insulating comb cover is provided; which includes a main body, the main body is provided with a heating comb head and an installation chamber located at an area of the heating comb head. The installation chamber is detachably connected to the heat-insulating comb cover. The heating comb head is provided with metal comb teeth, and the heat-insulating comb cover is provided with through holes corresponding to the metal comb teeth. The metal comb teeth pass through the through holes and are extended into the heat-insulating comb cover. By designing the heat-insulating comb cover as a detachable structure, a user can easily remove it for cleaning. Thus, the user can quickly remove dirt and broken hair from the straight hair comb, thereby maintaining the hygiene of the comb and increasing the favorability and satisfaction with this product.
