Solution Overview

Problem

Existing treatments for respiratory tract conditions, particularly those affecting the lower respiratory tract, face challenges in targeted delivery of medications due to the complexity of the respiratory system and the difficulty in identifying precise causes, often requiring systemic routes that may not effectively reach the target site.

Innovation Solution

A method involving the formulation of a dry powder mixture containing beta agonists, anticholinergics, and other active ingredients, which is mixed with a sterile diluent and nebulized to deliver the composition directly to the lower respiratory tract, using a nebulization technique to generate particles suitable for inhalation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If systemic delivery routes (oral or intravenous) are used to treat respiratory tract conditions, then medication can be administered easily, but the medication cannot effectively reach the target site in the lower respiratory tract

Engineering Contradiction:
Improveease of administrationVSAvoidtargeted delivery precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent uses a nebulizer device as an intermediary system that converts liquid medication into an aerosol form, enabling the medication to be delivered directly to the lower respiratory tract through inhalation. This intermediary mechanism bridges the gap between easy administration and precise targeting by utilizing the patient's own breathing process as the delivery vehicle

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention employs pneumatic principles through the nebulizer device, which uses compressed air or oxygen to generate aerosol particles from the liquid medication. This pneumatic mechanism enables the medication to be transformed into a breathable aerosol form that can reach deep into the lower respiratory tract, achieving both ease of administration and precise target delivery

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Manufacturing precision

If localized application of medications is used to target specific respiratory conditions, then treatment precision is improved, but the complexity of identifying precise causes and locations increases

Engineering Contradiction:
Improvetargeted delivery precisionVSAvoiddiagnosis and targeting complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The nebulizer device serves multiple functions: it can deliver various types of medications (bronchodilators, corticosteroids, antibiotics, mucolytics) to different respiratory conditions (asthma, COPD, bronchitis, pneumonia, cystic fibrosis). This multi-functionality allows a single device to address diverse respiratory conditions without requiring complex diagnostic equipment or multiple specialized devices

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention segments the respiratory tract treatment by delivering medication directly to specific affected areas through aerosol inhalation. The aerosol particles naturally deposit in different regions of the respiratory tract based on particle size and breathing pattern, enabling targeted delivery to upper or lower respiratory tract without requiring complex positioning or delivery mechanisms

Inventive Principle:
Principle #1Segmentation
