Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users purchase and manage multiple makeup brushes for different cosmetic applications, then different cosmetics can be applied on user's face, but it is inconvenient and costly

Engineering Contradiction:

Improveability to apply different cosmeticsVSAvoidconvenience of managing multiple brushes

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The makeup brush system is divided into a reusable handle and interchangeable brush heads. Each brush head is designed as a separate, detachable component that can be easily removed and replaced. This segmentation allows users to have multiple brush functions without managing multiple complete brushes, reducing complexity while maintaining versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A single handle is designed to be compatible with multiple types of brush heads through a universal attachment mechanism. The magnetic coupling system and actuator provide a common interface that works with various brush head types, enabling one handle to perform multiple makeup application functions that previously required separate brushes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If users purchase and manage multiple makeup brushes for different cosmetic applications, then different cosmetics can be applied on user's face, but it is costly

Engineering Contradiction:

Improveability to apply different cosmeticsVSAvoidnumber of brushes to purchase

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

By separating the expensive handle component from the brush head components, the system allows users to invest in a single high-quality handle and replace only the brush heads as needed. This segmentation reduces the total number of complete brushes users need to purchase while maintaining access to multiple brush types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The universal handle design with standardized magnetic coupling and actuator mechanism enables compatibility with multiple brush head types. Users can purchase one handle and acquire various brush heads for different cosmetic applications, reducing the total quantity of brushes needed compared to traditional separate brush purchases.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If a magnetic switchable device is used to enable selective attachment of brush heads, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveease of attachment and detachmentVSAvoidcomplexity of magnetic switchable device

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system replaces traditional mechanical attachment mechanisms (such as screws, clips, or snap-fits) with a magnetic coupling system. The magnetic attraction provides automatic alignment and secure attachment without requiring manual manipulation of mechanical fasteners, significantly improving ease of operation. The actuator mechanism uses magnetic field modulation rather than complex mechanical actuation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic switchable device changes the magnetic field parameters (strength, polarity, or distribution) to control attachment and detachment. By modulating the magnetic field rather than using mechanical movements, the system achieves easy operation with a simplified actuation mechanism. The magnetic properties are adjusted to provide strong attachment when engaged and easy release when the actuator is activated.

Inventive Principle:

Principle #35Parameter changes
