Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substances for UV protection and antimicrobial applications are often costly, toxic, or ineffective over time, and there is a need for biocompatible and biodegradable materials that can provide both UV protection and antimicrobial properties, especially for consumer products like food and beverage containers.
Innovation Solution
Development of biological devices and extracts produced from microbial cells transformed with DNA constructs encoding proteins such as zinc-related protein/oxidase, silicatein, silaffin, alcohol dehydrogenase, and optionally lipase, which are used to create anti-microbial and UV-protective compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional UV-absorbing chemicals are used, then UV protection is achieved, but toxicity and harmful side effects occur
Solution Approach 1:
The patent uses biodegradable organic compounds that naturally degrade in the environment, replacing persistent toxic UV filters. These compounds provide temporary UV protection but break down into harmless substances, eliminating long-term toxicity concerns while maintaining effective UV absorption during their functional lifetime
Solution Approach 2:
The patent modifies the chemical parameters of UV-filtering substances by using naturally occurring organic compounds with different molecular structures than traditional synthetic filters. This changes their toxicity profile from harmful to benign while preserving their UV-absorbing capabilities through natural photoprotective mechanisms
2Object-affected harmful factors
If antibiotics and antiseptic products are applied to control harmful microbial species, then microbial growth is inhibited, but microorganisms acquire antibiotic resistance
Solution Approach 1:
The patent changes the mechanism of antimicrobial action from antibiotic-based interference with microbial metabolism to physical mechanisms such as UV radiation damage to microbial DNA and cell structures. This fundamental parameter change in the mode of action prevents the development of resistance while maintaining effective microbial control
Solution Approach 2:
The patent converts the harmful effect of UV radiation into a beneficial antimicrobial tool. By using controlled UV exposure or UV-absorbing compounds that generate reactive oxygen species, the system exploits UV's ability to damage microbial cells while protecting human tissues, turning a potentially harmful radiation into a useful disinfection mechanism
3Object-affected harmful factors
If antibiotics or antiseptic products are applied to surface layer, then microbial control is achieved, but they wear or wash off losing effectiveness
Solution Approach 1:
The patent implements self-service through multiple mechanisms: UV-absorbing compounds are integrated into the material matrix providing continuous protection without application, antimicrobial surfaces use inherent material properties rather than applied coatings, and photodynamic systems generate active species in situ when exposed to light, eliminating the need for reapplication while maintaining persistent microbial control
Solution Approach 2:
The patent uses composite material structures where UV filters, antimicrobial agents, and base materials are integrated at multiple levels. This creates a multi-functional composite that simultaneously provides UV protection and antimicrobial activity with enhanced durability, as the multiple components work together and support each other's persistence on or within the surface
