Rotating Respirator Connection Device Preventing Port Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respirator systems face issues with foreign objects falling into open ventilation ports when assembled in a top-bottom configuration, leading to potential contamination and space inefficiency.
Innovation Solution
A respirator system with a connection device that rotates from a connection position to a rest position when the humidifier is separated, preventing foreign objects from entering the ports and allowing for a more compact assembly by positioning ports horizontally or vertically downward, utilizing an elastic member for automatic resetting and a protrusion mechanism for easy rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the humidifier and host machine are assembled in a top-bottom direction to reduce space occupation, then the space efficiency is improved, but foreign objects may easily fall into the ventilation ports that are open upward
Solution Approach 1:
The connection device is designed to be rotatable, allowing the ventilation ports to dynamically change their opening direction. When the humidifier is separated from the host machine, the connection device rotates to position the ports downward, preventing foreign objects from falling in while maintaining the compact top-bottom assembly configuration during operation.
Solution Approach 2:
The connection device automatically rotates to the correct position through its own mechanical design without requiring external intervention. The elastic member provides restoring force that naturally positions the ports downward when disconnected, making the system self-protecting against foreign object intrusion.
2Ease of operation
If the ventilation ports are open upward or upward obliquely to facilitate assembly in top-bottom direction, then the assembly ease is improved, but foreign objects may easily fall into the ports
Solution Approach 1:
The connection device transitions from a static upward-opening configuration during assembly to a dynamic state where it can rotate to a downward-opening position when disconnected, eliminating the foreign object intrusion risk while preserving assembly ease.
Solution Approach 2:
The orientation parameter of the ventilation ports is changed from fixed upward to variable, allowing the ports to rotate and change their opening direction based on whether the humidifier is connected or disconnected, thus preventing foreign object intrusion.
3Object-affected harmful factors
If the connection device rotates to a rest position with ports facing downward to prevent foreign objects, then the protection against foreign objects is improved, but the device complexity increases
Solution Approach 1:
The connection device incorporates a simple rotational mechanism with an elastic restoring element, adding minimal complexity while achieving the protective function of preventing foreign objects from entering the ventilation ports when disconnected.
Solution Approach 2:
The elastic member provides automatic restoring force that naturally returns the connection device to the protected downward-position, eliminating the need for complex control systems, motors, or sensors, thus keeping the device complexity low while maintaining effective protection.

AI summary
A ventilator system comprising: a ventilator having a first side provided with a first port; a humidifier having a second side engaging with the ventilator and provided with a second port; and a connection device provided on the first side of the ventilator or the second side of the humidifier and used to connect the first port of the ventilator with the second port of the humidifier. The connection device comprises: a first port, a second port and an airflow channel connecting the first port with the second port, wherein when the humidifier is separated from the ventilator, the connection device is capable of rotating from a connection position connecting the first port and the second port to a closed position for preventing foreign objects from falling into the first port and the second port. The ventilator system resolves issues of foreign objects falling into connection ports of a ventilator.
