Solution Overview

Problem

Current treatments for chronic venous insufficiency (CVI) are inadequate in addressing the underlying venous issues and their complications, such as swelling, inflammation, and varicose veins, as they often rely on compression stockings, injections, or surgical procedures, which may not fully alleviate symptoms or prevent recurrence.

Innovation Solution

A combination composition comprising L-carnitine or propionyl-L-carnitine, troxerutine, and hesperidine, which exhibit a synergistic effect in improving venous health by enhancing circulation, reducing inflammation, and preventing venous hypertension, administered orally or topically to treat and prevent CVI and its complications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If compression stockings are used to treat CVI, then venous pressure is reduced and circulation is improved, but patient compliance is poor and symptoms recur upon removal

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidpatient compliance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical compression system (stockings) with a biochemical system using L-carnitine and propionyl-L-carnitine that work internally to improve venous function, eliminating the need for external mechanical compression devices that require patient compliance

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention enables the body's own systems to treat CVI by using carnitine derivatives that enhance endogenous energy metabolism in vein walls and improve autonomous venous pump function, allowing the body to self-regulate venous pressure without external devices

Inventive Principle:
Principle #25Self-service

2Reliability

If surgical procedures are performed to correct CVI, then venous valve function is restored, but treatment complexity and recovery time increase

Engineering Contradiction:
Improvevenous valve functionVSAvoidtreatment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses oral supplementation of L-carnitine and propionyl-L-carnitine as a simple, non-invasive, temporary treatment that accumulates in the body to produce sustained effects, replacing complex surgical interventions with a straightforward supplementation approach

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention changes the biochemical parameters within vein walls by increasing carnitine levels, which improves energy metabolism and venous muscle function, thereby restoring venous valve function through biochemical modification rather than surgical mechanical repair

Inventive Principle:
Principle #35Parameter changes

3Reliability

If L-carnitine and propionyl-L-carnitine are used together, then synergistic effect is achieved in improving venous function, but formulation complexity increases

Engineering Contradiction:
Improvevenous function improvementVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines L-carnitine and propionyl-L-carnitine in a single formulation where the two compounds work synergistically - L-carnitine provides baseline metabolic support while propionyl-L-carnitine enhances energy production and has anti-inflammatory effects, creating a unified treatment approach

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite pharmaceutical formulation containing both L-carnitine and propionyl-L-carnitine along with excipients, where the combination of active ingredients produces synergistic effects that exceed the sum of individual components, analogous to composite materials achieving superior properties

Inventive Principle:
Principle #40Composite materials
