Ventilator Pneumatic Block Module Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilators are mechanically complex devices that require highly trained personnel for servicing and repair, with a multitude of tubes and connections that can be cumbersome and prone to misconnection.
Innovation Solution
The development of a pneumatic block module that consolidates air passages within a ventilator, featuring a volute assembly with a blower and air passages, a casing that encloses the volute assembly, and a removable inlet filter assembly, which simplifies the ventilator's mechanical complexity and facilitates easier maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ventilators use multiple separate tubes and mechanical connections for air passages, then the ventilator can perform complex ventilation functions, but the device complexity increases and requires highly trained personnel for servicing
Solution Approach 1:
The patent consolidates multiple separate air passages and mechanical connections into a single integrated pneumatic block module. This module contains all necessary air passages, blowers, and connections pre-assembled together, reducing the overall mechanical complexity while maintaining the ability to perform complex ventilation functions through the integrated design
2Adaptability or versatility
If conventional ventilators use multiple separate tubes and connections, then the ventilator can accommodate different ventilation modes, but the ease of operation decreases due to cumbersome connections
Solution Approach 1:
The patent divides the ventilator into modular components, with the pneumatic block module being a self-contained unit that can be easily removed and replaced. This segmentation allows different ventilation modes to be achieved through the integrated module design while simplifying maintenance operations, as the entire pneumatic assembly can be serviced as one unit rather than dealing with multiple separate tubes and connections
3Adaptability or versatility
If conventional ventilators use multiple separate mechanical connections, then the ventilator can provide comprehensive respiratory support, but the ease of repair deteriorates due to numerous components
Solution Approach 1:
The patent merges all pneumatic components including air passages, blowers, valves, and connections into a single replaceable pneumatic block module. This consolidation maintains comprehensive respiratory support capabilities while dramatically improving ease of repair, as technicians can service or replace the entire module as one unit rather than troubleshooting and repairing multiple separate mechanical connections throughout the device
