Problem
Traditional ear irrigation methods using syringes or rudimentary tools are inefficient, uncomfortable, and often ineffective for removing stubborn earwax, leading to issues like hearing loss and infections.
Innovation Solution
An irrigation and suction device with a specialized fluid appendage featuring a primary and secondary channel configuration, including a dogleg and concentric lumen portions, and a nozzle design that extends beyond the main tip, combined with a vacuum pump and fluid reservoir, allows for controlled fluid delivery and suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional manual syringes or rudimentary tools are used for ear irrigation, then the device complexity is low, but the effectiveness and efficiency of earwax removal is poor
Solution Approach 1:
The device is divided into multiple functional components: a fluid reservoir for irrigation solution, a vacuum pump for suction, and a fluid appendage with separate primary and secondary channels. The primary channel delivers fluid while the secondary channel removes debris, allowing each component to be optimized for its specific function and improving overall effectiveness without excessive complexity
Solution Approach 2:
The device combines irrigation and suction functions into a single integrated system. The fluid appendage contains both a primary channel for fluid delivery and a secondary channel for debris removal, merging two previously separate operations into one coordinated device that improves reliability while maintaining manageable complexity
2Reliability
If traditional manual irrigation methods are used, then the ease of operation is simple, but the user comfort and effectiveness for stubborn earwax is insufficient
Solution Approach 1:
The manual mechanical action of syringes is replaced with an automated vacuum pump system that creates negative pressure for suction. The vacuum pump automatically draws fluid and debris through the secondary channel, providing effective removal of stubborn earwax without requiring manual effort from the user
Solution Approach 2:
The device performs the irrigation and suction functions automatically once activated. The vacuum pump self-regulates the suction process, and the coordinated operation of the primary and secondary channels eliminates the need for manual manipulation, improving ease of operation while maintaining high effectiveness
3Ease of operation
If a simple single-channel appendage is used, then the device complexity is low, but the ability to provide controlled fluid delivery and suction simultaneously is limited
Solution Approach 1:
The fluid appendage is segmented into two separate channels: a primary channel for fluid delivery and a secondary channel for suction. This segmentation allows each channel to be optimized for its specific function, enabling controlled fluid delivery and suction to occur simultaneously without interference, while the modular design keeps the overall structure manageable
4Productivity
If traditional irrigation methods are used, then the loss of time for preparation and administration is minimal, but the productivity and efficiency of the ear cleaning process is low
Solution Approach 1:
The device enables continuous operation by simultaneously delivering fluid through the primary channel and removing debris through the secondary channel. The vacuum pump maintains continuous suction while irrigation fluid is delivered, eliminating the need to stop and restart operations, thereby improving productivity without significantly increasing preparation time

AI summary
An ear irrigation and suction device, and methods of using the same, are disclosed. The irrigation and suction device includes a fluid reservoir, a vacuum pump, and a detachable fluid appendage. The fluid appendage includes a primary channel that delivers a negative pressure to remove debris from an ear canal through suction and a secondary channel that supplies fluid under positive pressure to the ear canal for effective irrigation. The device may also include a controller for managing various operational modes, allowing for customized ear irrigation and suction tailored to individual needs.
