Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snivel suction devices can cause damage to the nasal mucosa due to unintentional attachment of the suction outer tube, leading to higher vacuum pressures when the user is not aware of the issue.
Innovation Solution
A snivel suction device equipped with a pressure relief valve and sound member that alerts the user to potential nasal mucosa contact by reducing vacuum pressure and generating a sound when a predetermined pressure is reached, preventing injury and allowing for continuous suction and release operations without electric power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the suction device operates continuously to maintain suction functionality, then productivity is improved, but the risk of nasal mucosa damage increases due to unintentional attachment
Solution Approach 1:
The patent incorporates a pressure sensing mechanism that continuously monitors vacuum pressure levels and provides feedback to the control system. When pressure exceeds a safe threshold indicating potential mucosal contact, the system automatically activates an alarm and reduces suction power, enabling continuous operation with real-time safety monitoring and adjustment
Solution Approach 2:
The suction device employs dynamic power adjustment capability that allows the suction force to vary in real-time based on operating conditions. The system transitions between different suction power levels automatically, maintaining high productivity during normal operation while reducing power when abnormal conditions are detected, thus preventing mucosal damage without compromising overall effectiveness
2Productivity
If the suction device uses high vacuum pressure to improve suction efficiency, then productivity is improved, but the harmful effect on nasal mucosa increases
Solution Approach 1:
The system dynamically changes the vacuum pressure parameter based on real-time monitoring. During normal operation, high vacuum pressure maintains efficient suction. When the pressure sensor detects conditions indicating potential mucosal contact, the control system automatically reduces the vacuum pressure to a safer level, thus preventing damage while maintaining acceptable suction efficiency throughout the procedure
Solution Approach 2:
The device employs dynamic power adjustment capability that allows the suction force to vary in real-time based on operating conditions. The system transitions between different suction power levels automatically, maintaining high productivity during normal operation while reducing power when abnormal conditions are detected, thus preventing mucosal damage without compromising overall effectiveness
3Device complexity
If the suction device lacks pressure monitoring to simplify the structure, then device complexity is reduced, but the ability to detect and prevent nasal mucosa damage is lost
Solution Approach 1:
The patent incorporates a pressure sensing mechanism that continuously monitors vacuum pressure levels and provides feedback to the control system. When pressure exceeds a safe threshold indicating potential mucosal contact, the system automatically activates an alarm and reduces suction power, enabling continuous operation with real-time safety monitoring and adjustment
Solution Approach 2:
The system introduces an intermediary pressure sensing component that acts as a mediator between the suction mechanism and the control system. This intermediary element provides critical safety information without requiring complex integration into the main suction architecture, balancing structural simplicity with reliable protection through a dedicated monitoring function

AI summary
A snivel suction device includes a base plate, two pump cylinders, two pistons, two connection rods, a pedal and two casings. Each pump cylinder is provided with a manifold containing a suction check valve and a release check valve. Two suction pipes are connected between a suction tee and the suction check valves of the manifolds. Two release pipes are connected between a release tee and the release check valves of the manifolds. A relief valve is installed at one of the casings. The relief valve has a knob, an adjustment member, a bolt, a valve body, a spring, a plug and a sound member. By operating the two ends of the pedal alternately, the two pistons are operated to suck and release air. Particularly, the relief valve can be actuated when a higher vacuum pressure has occurred in the suction pipes so as to protect the user's nasal mucosa.
