Solution Overview

Problem

Heated applicators for cosmetic products like mascara cause the formula to dry out and the applicator head to become clogged with dried residue, leading to reduced product usability and customer frustration, as existing solutions do not adequately address the issue of heat exposure in the reservoir and on the applicator head.

Innovation Solution

A kit comprising multiple disposable reservoirs with a reusable heating applicator subassembly that allows the heat generating portion to be detached from the applicator head, reducing heat exposure and enabling the reservoir to be sealed, thus minimizing product degradation and clogging, with each reservoir containing a limited amount of product for multiple applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a heated applicator is used repeatedly to apply mascara, then the applicator can be used multiple times, but the formula in the reservoir dries out and the applicator head becomes clogged

Engineering Contradiction:
Improveapplicator usage durationVSAvoidproduct usability
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The invention divides the mascara system into separable components: a reusable heated applicator and replaceable reservoirs. This segmentation allows the reservoir to be replaced when product remains, preventing the applicator head from being exposed to heat without sufficient product, thereby eliminating the clogging problem while maintaining reusable applicator functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention implements a system where the reservoir is discarded and replaced rather than emptied completely. The reusable heated applicator is recovered and continues to be used with new reservoirs. This approach prevents the applicator head from being subjected to prolonged heat exposure with minimal product, which causes drying and clogging, while still providing extended usage through multiple reservoir replacements.

Inventive Principle:
Principle #34Discarding and recovering

2Power

If the applicator head is continuously attached to the heat generating portion, then heating function is maintained, but residual product dries out and builds up on the applicator head

Engineering Contradiction:
Improveheating functionVSAvoiddried residue buildup
Core Design Contradiction:
PowerVSObject-generated harmful factors

Solution Approach 1:

The invention makes the connection between the applicator head and heat generating portion dynamic rather than static. The applicator head can be detached from the heat generating portion when not in use or when the reservoir is being replaced. This dynamic separation prevents residual product on the applicator head from being continuously exposed to heat, thereby reducing dried residue buildup while maintaining heating functionality when needed.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If a full size mascara reservoir is used, then a saleable amount of product is provided, but the product is exposed to heat for tens of uses causing dry-out

Engineering Contradiction:
Improveproduct quantityVSAvoidheat exposure
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The invention segments the full-size product quantity into multiple smaller reservoirs that can be sequentially used with a single reusable applicator. Each reservoir contains enough product for a limited number of uses, after which it is replaced. This segmentation limits the duration of heat exposure for each reservoir's product, preventing dry-out while collectively providing a saleable quantity of product across multiple reservoirs.

Inventive Principle:
Principle #1Segmentation
