Solution Overview

Problem

Current simulators for respiratory systems provide only rudimentary representations of an organism's respiration and rely primarily on mechatronic designs without a comprehensive underlying framework, limiting their ability to depict complex respiratory situations.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a mechatronic design is used for respiratory simulation, then the device structure is relatively simple, but the simulation sophistication and ability to depict complex respiratory situations is limited

Engineering Contradiction:
Improvedevice structureVSAvoidsimulation sophistication
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system is divided into multiple independent modules including gas generation module, flow control module, pressure control module, and control unit. Each module performs a specific function and can be independently configured, allowing the system to achieve complex simulation capabilities through modular composition rather than monolithic design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces traditional mechatronic designs with a control-based system that uses electronic control units and mathematical models to regulate gas flow and pressure. This substitution of mechanical control with electronic control and mathematical simulation enables more sophisticated and adaptable respiratory scenarios without proportionally increasing mechanical complexity.

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

2Adaptability or versatility

If a comprehensive mathematical framework is established for respiration simulation, then the simulation capability is enhanced, but the device complexity increases

Engineering Contradiction:
Improvesimulation capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control unit serves multiple functions: it manages gas generation, regulates flow, controls pressure, and coordinates the mathematical simulation framework. This multi-functional design consolidates complexity into a single control unit rather than distributing it across multiple specialized devices, achieving comprehensive simulation capability without proportionally increasing overall device complexity.

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

Solution Approach 2:

The patent introduces a mathematical model as an intermediary between the physical gas system and the control unit. This mathematical framework acts as a mediator that translates physiological parameters into control signals for the gas modules, enabling sophisticated simulation capabilities while keeping the physical device structure manageable through abstracted control logic.

Inventive Principle:
Principle #24Intermediary (Mediator)
