Solution Overview

Problem

Current respiratory support devices lack improved sterility and ease of use, particularly in emergency situations, where they need to provide sterile air efficiently and be easily operable.

Innovation Solution

The development of respiratory support devices that utilize removable, inflatable, and deflatable cartridges, which can be easily replaced and operated with minimal force, featuring a mechanism with pivotally connected arms that form a plier-like structure for efficient inflation and deflation, ensuring sterile air delivery and user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional respiratory support device with a fixed bag is used, then the device structure is simple, but the sterility is compromised and ease of use in emergency situations is reduced

Engineering Contradiction:

ImprovesterilityVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into two main segments: a reusable main body and a disposable cartridge containing the inflatable bag. This segmentation allows the cartridge to be pre-packaged in sterile condition and discarded after use, ensuring sterility without requiring the entire device to be complex or disposable.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inflatable bag and associated sterile components are extracted into a separate removable cartridge that can be independently replaced. This extraction enables the sterile component to be handled separately from the non-sterile main device, maintaining sterility while keeping the overall device structure manageable.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If a traditional respiratory support device requires manual pumping, then the device structure is simple, but the force required for operation is high and ease of use is reduced

Engineering Contradiction:

Improveease of useVSAvoidforce required for inflation

Core Design Contradiction:

Ease of operationVSForce

Solution Approach 1:

The manual pumping mechanism is replaced with a mechanical actuating system comprising pivotally connected arms that utilize lever mechanics and mechanical advantage. This substitution reduces the input force required from the operator while maintaining the inflation function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The actuating mechanism employs movable pivotally connected arms that can dynamically adjust their position and leverage during operation. This dynamic structure allows the operator to apply force more efficiently at different stages of the inflation cycle, reducing overall force requirements compared to a static manual pump.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a disposable cartridge system is implemented, then sterility is improved, but the device complexity increases

Engineering Contradiction:

ImprovesterilityVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple functions are merged into the disposable cartridge: the inflatable bag, the sealing mechanism, and the connection interfaces are integrated into a single replaceable unit. This merging simplifies the overall system by consolidating sterile components that would otherwise require separate handling and assembly procedures.

Inventive Principle:

Principle #5Merging (Combining)

4Ease of operation

If a plier-like actuating mechanism with pivotally connected arms is used, then ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improveease of useVSAvoiddevice structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The pivotally connected arms serve multiple functions: they act as leverage multipliers during inflation, provide structural support for the cartridge, and enable compact folding when not in use. This multi-functionality justifies the added structural complexity by eliminating the need for separate components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Inventive Principle:

Principle #15Dynamics
