Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Houttuynia cordata extract is used directly, then the composition is simple to prepare, but the physiological activity and skin benefits are significantly weakened

Engineering Contradiction:
Improvephysiological activityVSAvoidpreparation process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies fermentation technology to transform the Houttuynia cordata extract through biological processes, changing its chemical composition and enhancing the content of active ingredients like quercetin. This parameter change in the extract's composition significantly improves its physiological activity and skin benefits while maintaining a relatively simple fermentation-based preparation process

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces lactic acid bacteria as an intermediary organism to ferment the Houttuynia cordata extract. These bacteria act as a mediator that transforms the raw extract into a more potent form, enhancing the physiological activity without requiring complex chemical processing methods

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If fermentation method is used to enhance physiological ingredients, then the skin barrier-strengthening and moisturizing effects are improved, but the manufacturing process becomes more complex

Engineering Contradiction:
Improveskin barrier-strengthening effectVSAvoidfermentation process complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The fermentation process changes the biochemical parameters of the Houttuynia cordata extract, increasing the concentration of active ingredients such as quercetin and other physiological compounds. This parameter enhancement directly improves the skin barrier-strengthening and moisturizing effects while using a biologically-based process that is relatively easier to control than complex chemical synthesis

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The lactic acid bacteria perform self-service by naturally fermenting the Houttuynia cordata extract and producing the desired active ingredients through their metabolic processes. This self-service capability of the bacteria simplifies the manufacturing process compared to manual extraction or complex chemical processing, as the system essentially produces the active compounds autonomously

Inventive Principle:
Principle #25Self-service
