Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional sunscreens and UV-blocking measures are used to protect skin from ultraviolet light, then skin protection from UV damage is improved, but the harmful inflammatory effects of ultraviolet light are not effectively inhibited

Engineering Contradiction:

Improveskin protection from UV damageVSAvoideffectiveness in inhibiting inflammation

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent converts harmful ultraviolet light into beneficial longer wavelengths through wavelength conversion substances. Instead of merely blocking UV light, the invention transforms it into visible light (450-700nm) that can inhibit inflammatory substance expression, thereby turning the harmful UV exposure into a therapeutic effect for skin inflammation and erythema.

Inventive Principle:

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

Solution Approach 2:

The invention changes the wavelength parameter of incident light from ultraviolet range (200-400nm) to visible light range (450-700nm) using wavelength conversion substances. This parameter transformation allows the light to exert anti-inflammatory effects rather than causing damage, resolving the contradiction between UV protection and inflammation inhibition.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If ultraviolet light is blocked completely to prevent skin damage, then skin safety is improved, but the potential therapeutic benefits of controlled UV exposure are lost

Engineering Contradiction:

Improveskin safetyVSAvoidtherapeutic utility

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The wavelength conversion substance acts as an intermediary between ultraviolet light and skin cells. It absorbs harmful UV light and re-emits it as beneficial visible light, mediating the interaction to achieve both safety and therapeutic benefit. This intermediary approach allows controlled transformation rather than complete blocking.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Rather than discarding UV light as purely harmful, the invention converts it into beneficial visible light that triggers anti-inflammatory responses. This conversion approach maintains skin safety while unlocking therapeutic potential, making the system adaptable for treating inflammatory skin conditions.

Inventive Principle:

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

3Reliability

If wavelength conversion substances are used to convert ultraviolet light to longer wavelengths, then anti-inflammatory effects are improved, but the complexity of the composition increases

Engineering Contradiction:

Improveinflammation inhibition effectivenessVSAvoidcomposition complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs composite wavelength conversion substances comprising multiple components (phycobiliproteins, inorganic phosphors, vitamins, pigments) that work synergistically. This composite approach achieves effective wavelength conversion and anti-inflammatory effects while allowing flexible formulation to manage composition complexity based on specific application needs.

Inventive Principle:
