Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple ventilation apparatuses are used to ventilate multiple patients simultaneously, then each patient receives dedicated ventilation equipment, but the cost increases and availability decreases
Solution Approach 1:
The hose system is segmented into multiple independent branches (first hose branch, second hose branch, etc.), each capable of connecting to a different patient interface. This segmentation allows a single ventilation apparatus to serve multiple patients through separate, independent pathways, reducing the need for multiple apparatuses while maintaining reliable ventilation for each patient.
Solution Approach 2:
The ventilation apparatus is designed with universal capability to serve multiple patients simultaneously through the multi-branch hose system. The apparatus performs the function of ventilating not just one but multiple patients at the same time, increasing availability and reducing the total number of apparatuses needed in the system.
2Quantity of substance
If a single ventilation apparatus is used to ventilate multiple patients, then costs are reduced and availability increases, but the system complexity increases
Solution Approach 1:
The hose system is divided into distinct, modular branches with clear segmentation. Each branch is a separate, identifiable component that can be independently configured and managed. This modular segmentation simplifies the overall system complexity by making the multi-branch structure organized and manageable rather than chaotic.
Solution Approach 2:
The hose adapter serves as an intermediary component that connects the single ventilation apparatus to multiple hose branches. This intermediary element simplifies the connection architecture, providing a standardized interface point from which multiple patients can be connected without requiring complex direct connections from the apparatus to each patient.
3Productivity
If multiple patients are connected to a single ventilation apparatus through a hose system, then resource utilization improves, but the ease of operation decreases
Solution Approach 1:
The hose system is segmented into distinct branches, each with independent control capabilities. This segmentation allows operators to manage each patient's ventilation independently through separate branches, maintaining operational simplicity even while serving multiple patients simultaneously, thus preserving ease of operation while improving resource utilization.
Solution Approach 2:
The hose system incorporates adjustable elements such as valves in each branch that can be dynamically adjusted to control respiratory gas flow to individual patients. This dynamic adjustability allows operators to easily modify ventilation parameters for each patient independently, maintaining ease of operation while efficiently utilizing a single apparatus for multiple patients.
4Manufacturing precision
If independent pressure and flow adjustments are provided for each patient branch, then ventilation precision improves, but the device complexity increases
Solution Approach 1:
The valve system is segmented into independent valves for each hose branch, with each valve controlling pressure and flow for a specific patient. This segmentation provides precise independent control for each patient while keeping the overall system manageable through its modular, distributed architecture rather than a single complex centralized control system.
Solution Approach 2:
The system enables independent adjustment of ventilation parameters (pressure and flow) for each patient branch through individual valves. This parameter control capability allows precise customization of ventilation settings for each patient without requiring a single complex control mechanism, achieving high precision through simple, distributed parameter adjustment points.
