Solution Overview

Problem

Current sun-protecting formulations that block UV rays also reduce natural vitamin D production, leading to vitamin D deficiency and insufficiency, and there is a lack of effective solutions to maintain adequate systemic vitamin D levels while protecting against UV radiation.

Innovation Solution

Topical sun-protecting formulations that include a therapeutically effective amount of vitamin D, combined with sun-protecting agents, to compensate for reduced vitamin D production and treat or prevent vitamin D-related disorders and diseases, administered through a pharmaceutical carrier for topical application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If sun-protecting formulations with high SPF are used to block UV radiation, then protection against skin cancer and UV damage is improved, but natural vitamin D production is reduced leading to vitamin D deficiency

Engineering Contradiction:
ImproveUV radiation protectionVSAvoidvitamin D production
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent converts the harmful effect of UV blocking into a beneficial outcome by formulating sunscreens that not only block UV radiation but also provide therapeutic vitamin D to compensate for the blocked natural production. The harmful UV blocking is paired with a beneficial vitamin D delivery system, turning the trade-off into a dual-benefit formulation.

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

Solution Approach 2:

The patent changes the concentration parameter of vitamin D in the sunscreen formulation to therapeutically effective levels (e.g., 1000-10000 IU per application). This parameter change ensures that even though natural vitamin D production is blocked, the exogenous vitamin D in the formulation compensates and maintains adequate serum vitamin D levels.

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If sun exposure is increased to maintain natural vitamin D production, then vitamin D levels are improved, but skin cancer risk and UV damage increase

Engineering Contradiction:
Improvevitamin D productionVSAvoidskin cancer risk
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent segments the vitamin D acquisition process from UV exposure by delivering vitamin D topically through sunscreen formulation rather than relying on UV-induced synthesis. This separation allows vitamin D benefit without the harmful UV exposure, effectively decoupling the beneficial effect from the harmful mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces topical vitamin D as an intermediary substance that mediates between the need for vitamin D and the desire to avoid UV exposure. Instead of using UV radiation as the delivery mechanism for vitamin D, the formulation uses direct topical application, serving as an intermediary that bypasses the harmful UV step.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If sunscreens with SPF 8 or higher are used to protect against UV rays, then UV protection is improved, but vitamin D producing UV rays are blocked interfering with natural vitamin D production

Engineering Contradiction:
ImproveUV ray blockingVSAvoidvitamin D production
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent merges two previously separate functions into one formulation: UV protection and vitamin D supplementation. By combining high SPF sun-protecting agents with therapeutically effective vitamin D in a single sunscreen product, the formulation simultaneously provides both UV blocking and vitamin D maintenance, eliminating the need to choose between the two functions.

Inventive Principle:
Principle #5Merging (Combining)
