Innovation Solution

A method using a licorice hydrophobic extract to reduce and stabilize oxidized coenzyme Q10, forming a composition with reduced coenzyme Q10 and licorice hydrophobic extract, which improves the stability and safety of reduced coenzyme Q10 for use in various products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If general reducing agents (sodium borohydride, sodium dithionite) are used to reduce oxidized coenzyme Q10, then reduced coenzyme Q10 can be obtained, but the product requires further processing to become usable for edibles and cosmetics

Engineering Contradiction:
Improveproduction efficiency of reduced coenzyme Q10VSAvoidease of use for edibles and cosmetics
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent uses ascorbic acid as an intermediary reducing agent that naturally occurs in food systems, replacing harsh chemical reducing agents. This mediator enables the reduction of oxidized coenzyme Q10 to a form suitable for edibles and cosmetics without requiring extensive additional processing, thus resolving the contradiction between production efficiency and ease of manufacture.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If oxygen is completely removed during processing and preservation, then reduced coenzyme Q10 stability is improved, but complete removal or blocking of oxygen is extremely difficult and remaining oxygen exerts adverse effects

Engineering Contradiction:
Improvestability of reduced coenzyme Q10VSAvoidcomplexity of oxygen removal system
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent employs ascorbic acid, which naturally occurs in food systems and automatically reduces oxidized coenzyme Q10 back to its reduced form without requiring external intervention or complex oxygen removal systems. This self-service mechanism maintains reduced coenzyme Q10 stability through the inherent reducing capability of ascorbic acid, resolving the contradiction between stability improvement and system complexity.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If ascorbic acid is used as a reducing agent, then reduced coenzyme Q10 can be stabilized, but ascorbic acid is oxidized to produce dehydroascorbic acid which causes quality problems and side effects

Engineering Contradiction:
Improvestability of reduced coenzyme Q10VSAvoiddehydroascorbic acid by-products
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The patent optimizes the ascorbic acid to oxidized coenzyme Q10 ratio to exceed the stoichiometric requirement, ensuring complete reduction while minimizing dehydroascorbic acid formation. By controlling this parameter and using the natural reducing capability of ascorbic acid in food-grade amounts, the patent achieves stabilization of reduced coenzyme Q10 while keeping harmful by-products within acceptable limits for edible and cosmetic applications.

Inventive Principle:
Principle #35Parameter changes
