Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional sunscreens use non-natural UV filters and nanoparticles, then UV protection effectiveness is improved, but skin safety and environmental safety deteriorate due to toxicity and allergenicity

Engineering Contradiction:

ImproveUV protection effectivenessVSAvoidskin safety

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the fundamental parameter of UV filter composition from synthetic chemical filters and nanoparticles to natural plant-derived filters. Specifically, it uses polyphenols from olive leaves, flavonoids from citrus peels, and carotenoids from paprika, which provide equivalent UV protection without the toxic effects of conventional filters. This parameter change resolves the contradiction by maintaining protection effectiveness while eliminating skin safety concerns.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent converts potentially harmful substances into beneficial ones by replacing toxic synthetic UV filters with natural plant compounds. The polyphenols, flavonoids, and carotenoids from natural sources provide the same protective function against UV radiation while offering additional skin benefits such as antioxidant properties and anti-inflammatory effects, thus converting a harmful approach into a beneficial one.

Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If conventional sunscreens use natural ingredients, then skin safety is improved, but product texture deteriorates by becoming greasy and whitening

Engineering Contradiction:

Improveskin safetyVSAvoidproduct comfort

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent creates a composite formulation that combines multiple natural UV filters (polyphenols, flavonoids, carotenoids) with carefully selected natural emollients and carriers. This composite approach allows the natural ingredients to work synergistically, providing both skin safety and improved texture. The composite material ensures even distribution of the natural filters, preventing the whitening effect while maintaining the protective benefits.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent applies different natural ingredients to specific functional requirements: polyphenols and flavonoids for UV protection, carotenoids for additional antioxidant benefits, and specific natural oils as carriers. Each ingredient is positioned to optimize its local function, ensuring that the natural components provide protection without creating a greasy or whitening appearance on the skin.

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent converts harmful synthetic chemical filters into beneficial natural plant compounds. The polyphenols from olive leaves, flavonoids from citrus peels, and carotenoids from paprika provide equivalent UV protection while being biodegradable and non-toxic to marine life. This conversion eliminates the environmental harm associated with conventional filters like oxybenzone and avobenzone, which are known to harm coral reefs and aquatic ecosystems.
