Split Applicator With Nested Dual-Hardness Heads for Uniform Makeup

Solution Overview

Problem

Existing cosmetic brushes with integrally manufactured brush heads made of soft materials result in non-uniform makeup application due to their soft nature, affecting the makeup effect.

Innovation Solution

A split applicator design featuring a first application head with a lower hardness and a second application head with higher hardness, where the second head supports the first head during makeup application, enhancing the makeup effect and preventing detachment with a strong bonding mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the brush head is made of soft material for makeup application, then the brush can be comfortable to use, but the application uniformity deteriorates

Engineering Contradiction:

ImprovecomfortabilityVSAvoidapplication uniformity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The brush head is divided into two separate parts: a soft first application head for comfort and a hard second application head for precision. This segmentation allows each part to have optimized properties for its specific function, resolving the contradiction between comfort and application uniformity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second application head is nested inside the first application head, with the harder second head providing structural support to the softer first head. This nesting arrangement allows the soft outer head to maintain comfort while the hard inner head ensures application uniformity by preventing deformation.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Manufacturing precision

If the brush head is made of hard material for precise application, then the application uniformity improves, but the comfortability deteriorates

Engineering Contradiction:

Improveapplication uniformityVSAvoidcomfortability

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The brush head is divided into two separate parts: a soft first application head for comfort and a hard second application head for precision. This segmentation allows each part to have optimized properties for its specific function, resolving the contradiction between comfort and application uniformity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second application head is nested inside the first application head, with the harder second head providing structural support to the softer first head. This nesting arrangement allows the soft outer head to maintain comfort while the hard inner head ensures application uniformity by preventing deformation.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Manufacturing precision

If the second application head is added inside the first application head, then the application uniformity improves, but the device complexity increases

Engineering Contradiction:

Improveapplication uniformityVSAvoidstructure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The second application head is nested inside the first application head, utilizing the existing structure of the first head to house the second head. This approach minimizes additional structural complexity while achieving the goal of improved application uniformity through the dual-head design.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The two application heads are combined into a single integrated brush head assembly, where the first and second heads work together as one unit. This merging reduces the need for separate components and simplifies the overall device structure while maintaining the benefits of having both soft and hard application surfaces.

Inventive Principle:

Principle #5Merging (Combining)
