Smartphone Mount Ear Examination Tool for Microsuction Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ear wax removal methods, such as ear irrigation, are often invasive, risky, and require specialized equipment, limiting their accessibility and safety, while microsuction is safer but more complex and expensive, typically performed in a hospital setting.
Innovation Solution
An ear examination tool integrating a smartphone with a speculum mount and optical elements to provide a low-cost, easily deployable visualization platform for ear canal inspection during irrigation or microsuction, allowing for improved visualization and access with a smartphone's camera and light source, and a cannula grip for easy manipulation of microsuction tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ear irrigation is used for wax removal, then the procedure is simple and widely accessible, but it carries safety hazards including trauma, perforation, and otitis externa
Solution Approach 1:
The patent introduces a smartphone-based visualization system as an intermediary tool that enables direct vision during irrigation procedures. This mediator allows healthcare professionals to see into the ear canal through the smartphone camera and screen, providing real-time visual feedback without requiring complex microscope equipment, thereby maintaining procedure simplicity while improving safety
Solution Approach 2:
The patent replaces the traditional mechanical binocular operating microscope system with a smartphone-based optical system. By using the smartphone's camera, screen, and basic optical elements (lens, light source), the system substitutes complex mechanical microscopy equipment with a more accessible digital visualization platform that achieves similar safety outcomes
2Reliability
If ear microsuction is performed with binocular operating microscope, then safety and visualization are improved, but the apparatus becomes more complex and expensive
Solution Approach 1:
The patent extracts the essential visualization function from the complex binocular operating microscope system and implements it using a smartphone's existing camera and display capabilities. By taking out only the necessary optical components (lens, light source, mounting structure) and combining them with the smartphone's built-in features, the system achieves safe visualization without requiring the full complexity of traditional microsuction equipment
Solution Approach 2:
The patent creates a simplified copy of the binocular microscope's visualization capability using a smartphone. The smartphone camera captures images through the speculum, and the screen displays them with magnification and illumination, effectively copying the essential function of direct vision without replicating the entire complex microscope system
3Loss of information
If binocular operating microscope is used for microsuction, then direct vision is achieved, but the equipment is expensive and limited to hospital settings
Solution Approach 1:
The patent makes the visualization system universal by using a smartphone, which is a ubiquitous device already owned by most people. The system can be deployed in diverse settings (GP surgeries, community clinics, home care) because it relies on the smartphone's existing camera and display rather than specialized expensive equipment, thereby reducing information loss about ear canal conditions while eliminating the need for costly hospital-based microscopes

AI summary
An ear examination tool comprises a handle and a speculum mount coupled to the handle. The speculum mount is configured for retaining a disposable speculum. An spacing element is coupled to the handle and extends from the handle. A smartphone mount is coupled to the spacing element, and the spacing element is configured to maintain an optical separation distance between the speculum mount and the smartphone mount. The tool enables a clear view of the ear canal while allowing access by, and manipulation of, a microsuction tool being inserted into the ear canal. The extensive optical and data processing functionality of a "smartphone" can be integrated at low cost into an ear examination tool to provide a substantially improved piece of equipment for assisting in ear examination and microsuction of the ear.
