Solution Overview
Problem
Current topical nitric oxide delivery systems face challenges such as poor penetration through the skin barrier, leading to unsatisfactory delivery and potential skin irritations, and are often costly and inconvenient to apply.
Innovation Solution
A delivery system combining alpha-hydroxy acids with a nitric oxide source to enhance nitric oxide transport through the skin, utilizing alpha-hydroxy acids like glycolic acid to facilitate deeper skin penetration and improve the efficacy of nitric oxide delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional topical nitric oxide delivery systems are used, then nitric oxide can be applied to the skin surface, but poor penetration through the skin barrier prevents satisfactory delivery to deeper layers
Solution Approach 1:
The patent employs penetration enhancers as intermediary substances that facilitate the transport of nitric oxide through the skin barrier. These enhancers modify the skin barrier properties temporarily or form transient channels, allowing nitric oxide to reach deeper layers without requiring high concentrations that would cause irritation.
Solution Approach 2:
The patent modifies physical or chemical parameters of the delivery system, such as using liposomal encapsulation to change the delivery vehicle's properties, or adjusting pH and temperature conditions to optimize nitric oxide release and penetration through the skin barrier.
2Reliability
If higher concentrations of nitric oxide are applied to overcome skin barrier resistance, then deeper penetration may be achieved, but skin irritations and allergic reactions increase
Solution Approach 1:
Penetration enhancers serve as mediators that enable low-concentration nitric oxide to achieve deep penetration without direct contact between high concentrations of nitric oxide and sensitive skin tissues, thereby reducing irritation and allergic reactions.
Solution Approach 2:
The patent uses biodegradable carriers such as liposomes or nanoparticles that temporarily hold nitric oxide and release it gradually. These short-lived carriers protect the skin from direct exposure to harsh high concentrations while ensuring adequate delivery, then naturally decompose without causing long-term irritation.
3Adaptability or versatility
If various nitric oxide-generating materials are used, then different mechanisms of NO release can be explored, but production costs increase and application convenience decreases
Solution Approach 1:
The patent develops a universal delivery platform (such as liposomal or nanoparticle-based systems) that can accommodate multiple nitric oxide-generating materials and release mechanisms within a single formulation framework, maintaining ease of application while enabling versatile NO release strategies.
4Reliability
If complex nitric oxide delivery systems are designed to improve penetration, then delivery efficacy may increase, but manufacturing complexity and cost increase
Solution Approach 1:
The patent optimizes formulation parameters such as lipid composition, particle size, and encapsulation efficiency to achieve effective penetration with relatively simple manufacturing processes. By carefully controlling these parameters within standard ranges, complex delivery efficacy is achieved without requiring overly complicated production methods.
