Solution Overview
Problem
Current silicone products for medical and cosmetic applications face issues with wear, UV protection, and hygiene, particularly when exposed to the outside environment, and lack effective UV protection and breathability.
Innovation Solution
Development of silicone products with a breathable polyurethane outer cover providing UV protection exceeding 50 UPF, combined with a silicone gel coating on elastic materials like polyamide or polyester, and the inclusion of microcapsules for therapeutic or cosmetic applications, allowing for washability and reusability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silicone products are exposed to the outside environment, then they provide medical and cosmetic benefits, but they suffer from wear, UV damage, and hygiene issues
Solution Approach 1:
The patent applies a polyurethane outer cover layer that acts as a flexible protective shell over the silicone gel layer. This thin film structure provides UV protection and durability while maintaining the flexibility and comfort needed for skin contact applications, resolving the contradiction between protection and wear resistance.
Solution Approach 2:
The patent creates a composite structure combining silicone gel with polyurethane outer cover. This composite material approach integrates the therapeutic benefits of silicone with the protective properties of polyurethane, achieving both medical efficacy and environmental resistance including UV protection.
2Reliability
If silicone products are exposed to the outside environment, then they provide medical and cosmetic benefits, but they suffer from wear, UV damage, and hygiene issues
Solution Approach 1:
The polyurethane outer cover serves as a durable flexible shell that protects the underlying silicone gel from mechanical wear and environmental damage. This layered structure significantly extends the product lifespan while maintaining comfort and functionality.
Solution Approach 2:
The composite construction of polyurethane over silicone gel combines the wear resistance of polyurethane with the therapeutic properties of silicone, creating a product that is both durable and medically effective for long-term use.
3Reliability
If silicone products are exposed to the outside environment, then they provide medical and cosmetic benefits, but they suffer from wear, UV damage, and hygiene issues
Solution Approach 1:
The polyurethane outer cover acts as a protective barrier that shields the silicone gel from UV radiation and environmental contaminants. This thin film provides both UV protection and hygiene maintenance by preventing direct exposure to harmful external factors.
Solution Approach 2:
The composite structure integrates UV-blocking properties into the protective outer layer while maintaining the therapeutic silicone gel underneath, achieving simultaneous UV protection and hygiene preservation.
4Object-affected harmful factors
If silicone products use non-breathable materials, then they provide UV protection and durability, but they lack breathability and moisture management
Solution Approach 1:
The polyurethane outer cover is designed with porous or microporous structure that allows moisture vapor transmission while blocking UV radiation. This porous material enables breathability and moisture management without sacrificing UV protection or durability.
