Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing irrigation systems, such as those using pressurized sinus irrigation systems, often require power sources and complex vacuum controls, limiting their manual operation and effectiveness in delivering fluid to specific areas, especially for debridement and surface cleaning.
Innovation Solution
A manually powered irrigation system equipped with a valve system and a syringe assembly that includes two one-way valves, allowing for unidirectional fluid delivery through a nozzle, providing controlled pressure for effective irrigation and debridement, suitable for both living and non-living surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a pump mechanism is used to deliver fluid, then fluid delivery capability is improved, but device complexity increases
Solution Approach 1:
The system uses a self-contained manual pump mechanism that delivers fluid without requiring external power sources or complex control systems. The pump is integrated directly into the irrigation device, allowing it to service itself through manual operation.
Solution Approach 2:
The patent extracts the power source and control systems from the irrigation device, eliminating the need for electrical pumps and vacuum controls. Only the essential manual pumping mechanism is retained, simplifying the overall device while maintaining fluid delivery capability.
2Reliability
If vacuum control is used to control irrigation, then irrigation control capability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces complex electrical vacuum control systems with a simple manual pumping mechanism. The mechanical pump allows direct control of fluid delivery through manual operation, eliminating the need for electrical components and complex control circuits.
3Stress or pressure
If external power sources are used, then fluid delivery pressure is improved, but adaptability deteriorates
Solution Approach 1:
The manual pump mechanism allows dynamic adjustment of fluid delivery pressure through user control of the pumping action. The system can adapt to different irrigation needs by varying the pumping speed and force, providing versatile pressure control without requiring electrical power regulation.
