Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If curcuminoids are administered orally, then therapeutic effects are achieved, but poor bioavailability limits efficacy

Engineering Contradiction:
ImprovebioavailabilityVSAvoidpoor solubility and absorption
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies composite materials by combining curcuminoids with cyclodextrin inclusion complexes and phospholipid vesicles (liposomes or niosomes) to create a multi-component delivery system. The cyclodextrin inclusion complex enhances solubility by incorporating curcuminoid molecules within its hydrophilic cavity, while the phospholipid vesicle provides protective encapsulation and facilitates cellular uptake, collectively improving bioavailability

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the physical and chemical parameters of curcuminoids through formulation modifications. By adjusting the molecular environment through cyclodextrin inclusion and phospholipid encapsulation, the solubility parameter is significantly improved. The formulation also modifies the particle size and surface properties to enhance absorption characteristics in the gastrointestinal tract

Inventive Principle:
Principle #35Parameter changes

2Reliability

If curcuminoids are administered orally, then therapeutic effects are achieved, but rapid systemic metabolism reduces efficacy

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidsystemic metabolism rate
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies preliminary action by pre-encapsulating curcuminoids in phospholipid vesicles before administration. This pre-formulation protects the curcuminoids from premature metabolism in the gastrointestinal tract and bloodstream, allowing them to reach the systemic circulation in their active form. The phospholipid bilayer acts as a protective barrier against enzymatic degradation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes phase transitions by incorporating curcuminoids into phospholipid vesicles that can transition between different structural states. The liposomal or niosomal formulation allows curcuminoids to be sequestered in the hydrophobic core or incorporated into the bilayer, creating a reservoir that releases the active compound gradually, thereby extending duration of action

Inventive Principle:
Principle #36Phase transitions

3Reliability

If curcuminoids are administered orally, then therapeutic effects are achieved, but degradation in gastrointestinal tract reduces bioavailability

Engineering Contradiction:
ImprovebioavailabilityVSAvoidstability in gastrointestinal tract
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses cyclodextrin and phospholipids as intermediary substances that mediate between curcuminoids and the gastrointestinal environment. The cyclodextrin inclusion complex acts as a protective intermediary that shields curcuminoids from pH-induced degradation and enzymatic attack. The phospholipid vesicle serves as a second layer of protection, further stabilizing the compound against gastrointestinal conditions

Inventive Principle:
Principle #24Intermediary (Mediator)
