Visual Ear Irrigation Assembly for Controlled Cleaning Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ear-cleaning methods using forceps or ear spoons are unsafe as they lack visibility, making it difficult to control force during cleaning and often result in ear damage.
Innovation Solution
The aurilave and visual aurilave devices incorporate a water storage tank, housing, and ear-washing assembly with a water-pumping motor, nozzle, and transparent baffle, optionally with a camera and LED lighting, to provide controlled liquid cleaning and visibility, reducing the risk of ear damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If forceps or ear spoons are used for ear cleaning, then the cleaning action can be applied, but the user cannot see the situation in the ear canal making it difficult to control force, which leads to ear damage
Solution Approach 1:
The patent introduces a water-pumping motor as an intermediary mechanism that delivers controlled water flow through a nozzle into the ear canal. This mechanical intermediary system replaces direct manual insertion of forceps or spoons, allowing the user to control cleaning force indirectly through motorized water delivery rather than direct physical contact, thereby reducing the risk of ear damage while maintaining cleaning effectiveness
2Reliability
If manual ear cleaning with forceps or ear spoons is performed, then cleaning can be achieved, but without visibility the user cannot monitor the cleaning process, reducing safety
Solution Approach 1:
The patent replaces the purely mechanical manual cleaning system with an automated water-pumping motor system that provides both cleaning action and illumination. The LED light source integrated into the system substitutes for visual inspection by the user, providing real-time visibility of the ear canal condition during cleaning, thereby enhancing safety and allowing the user to monitor the cleaning process effectively
3Object-affected harmful factors
If a water-pumping motor and nozzle system is used for ear cleaning, then controlled liquid application is achieved improving safety, but the device structure becomes more complex
Solution Approach 1:
The patent integrates multiple functions into a single ear-washing assembly: the water-pumping motor provides controlled water delivery for cleaning, the LED light source provides illumination for visibility, and the nozzle system delivers both water and light into the ear canal. This multi-functional integration allows the device to achieve safe controlled liquid application while managing complexity through consolidation of functions in one assembly rather than requiring separate devices
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
These devices enable safe and effective ear cleaning by allowing controlled liquid application and real-time visualization, preventing damage to the ear canal and improving user safety and efficiency.
Implementation Method 1
a water-pumping motor arranged in the housing and electrically connected to the control plate, a water inlet pipe connected to a water inlet of the water-pumping motor at one end thereof, a water outlet pipe connected to a water outlet of the water-pumping motor at one end thereof
Implementation Method 2
an LED lamp plate arranged within the front cover and emitting light in a direction toward the nozzle
Implementation Method 3
a camera assembly including a camera arranged on the ear-washing assembly and a signal-transmitting module arranged on the control plate. The camera is electrically connected to the control plate and arranged close to the nozzle. The signal-transmitting module is configured to transmit video signals captured by the camera to a display apparatus
