Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If quercetin is used in its native form, then the dosage form contains high quercetin strength, but the poor flowability requires high proportion of excipients (20-70 wt%)

Engineering Contradiction:
Improvequercetin strengthVSAvoidflowability
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by modifying the physical state and density of quercetin through granulation processes. The quercetin is transformed from a low-density powder into high-density granules with improved flow properties, allowing the same quercetin strength to be achieved with significantly reduced excipient content (from 20-70 wt% to much lower proportions).

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates a composite structure by granulating quercetin with binding agents to form high-density granules. This composite approach improves the flowability and compressibility of quercetin while maintaining high active ingredient content, resolving the contradiction between quercetin strength and manufacturability.

Inventive Principle:
Principle #40Composite materials

2Device complexity

If quercetin is used in its native form, then the formulation is simple, but the poor flowability causes manufacturing inefficiencies and increased production times

Engineering Contradiction:
Improveformulation simplicityVSAvoidmanufacturing efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-granulating the quercetin into high-density form before the actual dosage form manufacturing. This pre-treatment of quercetin improves its flow and compression properties, enabling more efficient subsequent manufacturing steps and reducing overall production time without significantly complicating the formulation.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If quercetin is used in its native form, then no additional processing is required, but the low water solubility results in poor bioavailability

Engineering Contradiction:
Improveprocessing stepsVSAvoidbioavailability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent applies parameter changes by modifying the physical form of quercetin through granulation, which alters its surface area, density, and porosity characteristics. These physical parameter changes improve the wetting and dissolution properties of quercetin, thereby enhancing its water solubility and bioavailability without requiring chemical modification or complex additional processing steps.

Inventive Principle:
Principle #35Parameter changes
