Solution Overview

Problem

Current treatments for lung dysfunction associated with hyaline membrane formation, such as respiratory distress syndrome, are limited in efficacy and often carry severe side effects, with insufficient consideration given to plasminogen levels in patients.

Innovation Solution

Administering plasminogen, optionally with a plasminogen activator, to treat or prevent lung dysfunction by reducing hyaline membrane formation and associated microthrombi.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments for lung dysfunction are administered, then some therapeutic effect is achieved, but severe side effects occur and efficacy is limited

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidsevere side effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the biochemical parameter of plasminogen levels in patients to treat lung dysfunction. By administering plasminogen to patients with deficient levels, the treatment addresses the root cause of hyaline membrane formation without the severe side effects of conventional therapies.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Plasminogen acts as an intermediary substance that converts to plasmin through plasminogen activators, indirectly breaking down fibrin in hyaline membranes. This intermediary mechanism provides therapeutic effect while avoiding direct harsh interventions on lung tissue.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If plasminogen is administered to patients, then lung function recovery is enhanced and hyaline membrane formation is reduced, but the treatment requires consideration of individual plasminogen levels

Engineering Contradiction:
Improvelung function recoveryVSAvoidtreatment protocol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The treatment protocol monitors and adjusts plasminogen levels as a key parameter, administering plasminogen based on individual patient needs. This parameter-based approach improves lung function recovery while managing treatment complexity through targeted intervention.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If plasminogen and plasminogen activator are administered, then formation of microthrombi is reduced and lung function improves, but the mechanism requires understanding of fibrinolytic system dynamics

Engineering Contradiction:
Improvemicrothrombi reductionVSAvoidfibrinolytic system monitoring
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The treatment utilizes feedback from plasminogen level measurements and clinical response to adjust dosing of plasminogen and activators. This feedback mechanism reduces microthrombi formation effectively while managing the complexity of fibrinolytic system monitoring.

Inventive Principle:
Principle #23Feedback
