Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the amount of active agent in the skin care composition is increased, then the penetration amount into skin is improved, but the formulation stability and sensory feel deteriorate

Engineering Contradiction:
Improveamount of active agentVSAvoidformulation stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent replaces chemical penetration enhancers with a magnetic field-based delivery system. The magnetic array generates a magnetic field that interacts with diamagnetic skin care actives, enabling controlled penetration enhancement without increasing active agent concentration or using chemical enhancers that compromise formulation stability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state or properties of the delivery system by introducing a magnetic field with specific parameters (field strength, gradient, frequency). This allows control over active agent penetration depth and amount without altering the chemical composition or concentration of the active agents themselves.

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If chemical penetration enhancers are used to facilitate changes in skin permeability, then the penetration of skin care active is improved, but the risk of adverse side effects increases

Engineering Contradiction:
Improvepenetration of skin care activeVSAvoidadverse side effects
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes chemical penetration enhancers with a physical magnetic field-based system. The magnetic array generates a magnetic field that interacts with diamagnetic properties of skin care actives to enhance penetration, eliminating the need for chemical enhancers that cause irritation or adverse side effects.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic field acts as an intermediary between the applicator and the skin care active. The magnetic array generates a magnetic field that mediates the delivery process by interacting with the diamagnetic properties of the active agent, enabling controlled penetration without direct chemical interaction that could cause harm.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If iontophoresis is used to accelerate charged active agents across skin, then the penetration speed is improved, but the suitability for all target surfaces and barriers deteriorates

Engineering Contradiction:
Improvepenetration speedVSAvoidsuitability for all target surfaces
Core Design Contradiction:
SpeedVSAdaptability or versatility

Solution Approach 1:

The magnetic array system is designed to be universally applicable to different skin types, areas, and active agents with diamagnetic properties. Unlike iontophoresis which requires specific ionic structures and electrical contact, the magnetic field-based system can be applied to various target surfaces and barriers without requiring intimate electrical contact or adhesive electrodes.

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

Solution Approach 2:

The patent replaces the electrical field-based iontophoresis system with a magnetic field-based system. This substitution eliminates the limitations of iontophoresis regarding ionic structure requirements and electrical contact needs, making the delivery system more versatile and adaptable to different target surfaces and barriers.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Quantity of substance

If magnetophoresis techniques are used to create mobility and direction in active agent movement, then the penetration amount is improved, but the hardware requirements and cost increase

Engineering Contradiction:
Improvepenetration amountVSAvoidhardware requirements
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The magnetic array is designed as a simple, cost-effective component that can be integrated into consumer skin care applicators. Rather than requiring complex magnetophoresis hardware systems, the patent uses a straightforward magnetic array configuration that is economical to manufacture and dispose of, making the technology accessible for consumer use.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent extracts and utilizes only the essential magnetic field-generating components needed for penetration enhancement, eliminating unnecessary complex hardware. The magnetic array focuses on the core function of generating a magnetic field with appropriate strength and gradient, removing extraneous systems and reducing overall device complexity and cost.

Inventive Principle:

AI summary

A cosmetic skin care product that includes an applicator and a skin care composition. The applicator includes a uni-directional magnetic array with a pitch of between 1.7 and 2.5 and a magnetic field strength of between about 24.0 and 36.0 mT. The skin care composition includes palmitoyl-lysine-threonine-threonine-lysine-serine and a dermatologically acceptable carrier. The magnetic array is tailored to enhance penetration of the Pal-KTTKS into skin during application of the skin care composition. The applicator may include a second magnetic array juxtaposed on a first magnetic array to form a bi-directional array that enhances penetration of the Pal-KTTKS into skin.
