Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nasal irrigation devices lack a practical solution for using all three delivery methods (gravity, pressure, and suction) in a single device, and there is no device that offers a powered mechanism for combinations of these methods or for suction alone.
Innovation Solution
A hand-held nasal irrigation device that includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, fluid passageways, and a switch and valve assembly, allowing for controlled delivery of saline using gravity, pressure, and suction, with the option of powered suction to enhance the irrigation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single device incorporates all three delivery methods (gravity, pressure, and suction), then the device provides comprehensive irrigation options and improved therapeutic effectiveness, but the device complexity increases significantly
Solution Approach 1:
The device divides the irrigation system into separate functional modules: a gravity-fed saline reservoir, a pressure-driven pump mechanism, and a suction system with vacuum source. Each module can operate independently or in combination, allowing comprehensive irrigation options while maintaining manageable complexity through modular design
Solution Approach 2:
The device integrates multiple irrigation delivery methods (gravity, pressure, suction) into a single universal nasal irrigation device. The common fluid pathway and nasal interface accommodate all three methods, enabling one device to perform multiple therapeutic functions that previously required separate devices
2Productivity
If a powered mechanism is added to provide suction and pressure, then the irrigation effectiveness and mucociliary clearance are enhanced, but the device requires power sources and increases in complexity
Solution Approach 1:
The device replaces manual mechanical irrigation methods with powered mechanisms including an electric pump for pressure-driven saline delivery and a vacuum source for suction. This substitution enhances irrigation effectiveness and mucociliary clearance while consolidating multiple functions into integrated powered systems rather than separate manual devices
3Ease of operation
If the device includes integrated fluid passageways and control valves, then the ease of operation is improved, but the manufacturing complexity increases
Solution Approach 1:
The device merges the fluid passageways, control valves, pump mechanisms, and suction systems into an integrated assembly. The common fluid pathway serves all three irrigation methods, and the control system统一管理 all fluid flow, simplifying operation while requiring precision manufacturing of the integrated components

Function Achieved in This Case
The device provides a convenient, effective, and safe method for nasal irrigation, offering improved airflow, reduced nasal congestion, and enhanced mucociliary clearance, while minimizing mess and discomfort, and being adaptable to various nasal dimensions.
Implementation Method 1
a vacuum source, fluid passageways, and a switch and valve assembly, allowing for controlled delivery of saline using gravity, pressure, and suction
Implementation Method 2
The nasal interface engages a device user's nostrils to deliver saline solution by gravity from the source to the nasal cavity
Data Source
AI summary
Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of a user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The source of saline solution is disposed relative to the device to provide gravitational inducement of the saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and a relative vacuum from the effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of the user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.
