Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional respiratory systems lack flexibility and convenience, as they often require replacing entire components when one fails, and struggle to maintain stable humidity and temperature in dry or cold environments.
Innovation Solution
A respiratory system with separable functional units, including a gas supply unit and a detachable heating and humidifying unit that can be electrically and fluidly connected, featuring a rotatable adapter, a water tank with a heat conducting member, and a shield member for protection, allowing for modular replacement and improved humidification and heating efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional respiratory system uses a non-separable design, then the system structure is simple, but when a component fails the user must replace the entire system which increases cost and reduces flexibility
Solution Approach 1:
The respiratory system is divided into separable functional modules including a gas supply unit, a heating and humidifying unit, and a heated circuit. Each module can be independently replaced or maintained, allowing users to replace only the faulty component rather than the entire system, thereby increasing flexibility and reducing costs while maintaining manageable system complexity through standardized connection interfaces
2Ease of operation
If the adapter is fixed relative to the base, then the structure is stable, but the user cannot adjust the connection orientation which reduces convenience
Solution Approach 1:
The adapter is designed to rotate at least 90 degrees relative to the base, transforming a static fixed connection into a dynamic adjustable connection. This allows users to adjust the connection orientation according to different usage scenarios while maintaining structural stability through a locking mechanism that secures the adapter in the desired position during operation
3Temperature
If the respiratory system only inhales outside air, then the system structure is simple, but the produced breathing gas lacks moisture and has low temperature in dry or cold environments
Solution Approach 1:
The heating element and humidifying unit are merged into an integrated heating and humidifying unit that processes the breathable gas simultaneously. This combination allows the system to provide both heating and humidification functions without requiring separate independent systems, thereby improving breathing gas temperature and humidity while controlling the increase in system complexity through functional integration
4Ease of operation
If the electrical connection wire is rigid, then the electrical connection is stable, but the wire contacts and rubs the base when the adapter rotates which causes wear
Solution Approach 1:
The rigid electrical connection wire is replaced with a flexible cable that can accommodate the rotational movement of the adapter without contacting or rubbing the base. This flexible cable maintains stable electrical connection while allowing the adapter to rotate freely, preventing wear and maintaining connection reliability throughout the range of motion
