Solution Overview

Problem

Current weight-loss drugs for obesity have limited efficacy and safety concerns, necessitating the development of safer and more effective treatments.

Innovation Solution

Utilizing plasminogen as a weight-loss drug to address obesity by improving abnormal fat deposition and reducing body weight, administered alone or in combination with other therapies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing weight-loss drugs are used, then weight reduction can be achieved, but safety concerns and limited efficacy arise

Engineering Contradiction:
ImprovesafetyVSAvoidweight loss efficacy
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent changes the biochemical parameter by introducing plasminogen, a different molecular mechanism compared to existing drugs. Plasminogen activates plasmin which degrades extracellular matrix and adipose tissue, representing a fundamental parameter change in the weight loss mechanism that achieves both safety and efficacy

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If central appetite suppressants are used, then appetite control is improved, but mental and cardiovascular disease risks increase

Engineering Contradiction:
Improveappetite controlVSAvoidmental and cardiovascular disease risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent uses plasminogen as an intermediary substance that indirectly affects appetite and weight through plasmin activation and extracellular matrix degradation, rather than directly suppressing appetite centers in the brain. This intermediary mechanism avoids the harmful central nervous system effects of traditional appetite suppressants

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If lifestyle intervention is used, then safety is maintained, but weight loss effectiveness is insufficient when BMI ≥ 28

Engineering Contradiction:
ImprovesafetyVSAvoidweight loss effectiveness
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the weight loss mechanism into distinct biochemical pathways: plasminogen activation, plasmin generation, extracellular matrix degradation, and adipose tissue breakdown. This segmented approach targets specific metabolic pathways to achieve effective weight loss in severe obesity cases while maintaining safety

Inventive Principle:
Principle #1Segmentation
