Solution Overview

Problem

Existing cosmetic and medicinal dispensers are limited to applying products to the skin and do not provide thermal treatments, which are known to aid in healing and provide therapeutic sensations.

Innovation Solution

A cosmetic applicator with a thermal storage material applicator tip that can store and transfer thermal energy, allowing for both the application of products and thermal sensations such as cooling or warming to the skin, using materials like metal, ceramic, or stone, and a flexible design for ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing cosmetic and medicinal dispensers are used, then product application to skin is achieved, but thermal treatment capability is lost

Engineering Contradiction:

Improvethermal treatment capabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines product dispensing and thermal treatment functions into a single integrated applicator device. The applicator tip serves dual purposes: delivering cosmetic/medicinal products through its internal passage and providing thermal treatment through direct contact with the skin via its thermal storage material construction.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The applicator is designed as a multi-functional device that can simultaneously perform product application and thermal therapy. The thermal storage material enables the applicator to provide cooling or heating effects while dispensing products, making it suitable for various skincare applications including pain relief, inflammation reduction, and product delivery.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If thermal storage material is used in the applicator, then thermal treatment is provided, but manufacturing complexity increases

Engineering Contradiction:

Improvethermal treatment functionVSAvoidapplicator fabrication

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The applicator incorporates thermal storage material as a composite construction, combining it with the applicator body structure. This allows the applicator to maintain its shaping and structural integrity while providing thermal storage and transfer capabilities through the integrated material properties.

Inventive Principle:

Principle #40Composite materials

3Temperature

If the applicator is made from thermal storage material, then thermal energy transfer is enabled, but material selection options are limited

Engineering Contradiction:

Improvethermal energy transferVSAvoidmaterial selection

Core Design Contradiction:

TemperatureVSEase of manufacture

Solution Approach 1:

The patent specifies that the thermal storage material should have a melting point above the maximum operating temperature of the applicator, ensuring the material maintains its solid structure and shaping capability while providing the desired thermal storage and transfer properties during normal use.

Inventive Principle:

Principle #35Parameter changes
