Solution Overview

Problem

Existing mascara devices fail to effectively thicken, volumize, elongate, curve, and provide deep dense color to eyelashes, often resulting in issues like dry texture and insufficient curving.

Innovation Solution

A kit with multiple conditioning tanks containing different mascara compositions and a heating applicator device that allows for sequential application of compositions to achieve these effects, using a cap with heating means and rods with applicator elements that can be heated to optimize mascara application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If multiple different mascara compositions are applied sequentially to achieve thickening, volumizing, elongating, curving, and coloring effects, then the esthetic effects on eyelashes are enhanced, but the device complexity increases

Engineering Contradiction:
Improveesthetic effectsVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The mascara composition is divided into multiple distinct compositions, each targeting a specific effect (thickening, volumizing, elongating, curving, coloring). Each composition is stored in a separate tank and applied by a dedicated rod, allowing sequential application of specialized formulations to achieve comprehensive esthetic effects without requiring a single complex multi-functional composition.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heating device integrates multiple functions into a single system: it stores multiple compositions, heats them to optimal application temperatures, and applies them sequentially through different rods. The heating means serves all tanks and rods universally, eliminating the need for separate heating devices for each composition while maintaining simplified device operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If heating means are provided in the application device to heat the applicator element, then the mascara composition application is optimized, but the device complexity increases

Engineering Contradiction:
Improvemascara composition applicationVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The heating means is integrated into the application device structure, combining the heating function with the composition storage and application mechanisms. The heating element is positioned to simultaneously or sequentially heat multiple applicator elements as they are inserted into the tanks, consolidating thermal processing into a single unified system rather than requiring separate heating devices for each composition.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating device automatically activates when an applicator element is inserted into a tank, heating the composition and the applicator element without requiring manual intervention. The system self-regulates the heating process, eliminating the need for separate temperature control mechanisms for each application step and simplifying user operation.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If the applicator element is heated to heat the mascara composition, then the esthetic effects are maximized, but the energy consumption increases

Engineering Contradiction:
Improveesthetic effectsVSAvoidenergy consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The heating means activates in advance to heat the mascara composition in the tanks before the applicator element makes contact with it. This preliminary heating ensures that the composition is at the optimal temperature for application when the applicator is inserted, maximizing esthetic effects while minimizing the total heating time and energy consumption by pre-conditioning the composition.

Inventive Principle:
Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The kit enables simultaneous thickening, volumizing, elongating, curving, and coloring of eyelashes by using different compositions applied at varying temperatures, enhancing esthetic effects while maintaining safety.

Implementation Method 1

The heating means allow to heat the applicator element. When the applicator element is heated, it will also heat the mascara composition when it comes into contact with the same.

Methodology Applied
Scientific EffectHeating: Heating

Implementation Method 2

When the applicator element is heated, it will also heat the mascara composition when it comes into contact with the same.

Methodology Applied
Scientific EffectHeat transfer: Conduction (thermal)
