Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-ear monitoring systems face challenges in accurately customizing hearing aids to individual anatomy, particularly due to the natural curvature of the ear canal, which requires skilled manual operation and poses risks of injury, and lack efficient, cost-effective methods for precise scanning.
Innovation Solution
A system that uses a camera-mounted scanner with an eccentric observation point to capture 3D images of the ear canal, avoiding the need for manual deformation and reducing the risk of injury, and incorporates a learning machine to identify environments and adjust sound settings, while also capturing vital signs and health data for personalized monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If triangulation measurement methods are used to scan the ear canal, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical triangulation measurement systems with a simpler camera-based optical system. Instead of using projectors and multiple cameras at angles, the invention uses a single camera to capture images from an eccentric observation point, eliminating the need for complex mechanical measurement apparatus while maintaining the ability to obtain 3D ear canal data.
Solution Approach 2:
The patent creates a digital 3D copy of the ear canal geometry through image processing rather than direct physical measurement. By capturing images and processing them to generate a 3D model of the ear canal, the system obtains precise geometric data without requiring complex measurement hardware, thus reducing device complexity while maintaining measurement precision.
2Measurement precision
If manual deformation of the ear canal is performed to achieve free view of the eardrum, then measurement precision is improved, but object-affected harmful factors increase
Solution Approach 1:
The patent introduces a custom-fitted earpiece as an intermediary device that provides a clear optical path to the eardrum without requiring manual manipulation of the ear canal. The earpiece acts as a mediator between the camera and the ear canal, enabling safe and precise viewing of the eardrum through its specially designed geometry that fits the individual's ear anatomy.
Solution Approach 2:
The patent performs preliminary action by creating a custom-fitted earpiece before the scanning procedure. This earpiece is manufactured based on the individual's ear anatomy and is designed to provide optimal viewing angles to the eardrum. By preparing this custom device in advance, the system eliminates the need for manual deformation during the actual scanning process, thereby preventing injury while maintaining measurement precision.
3Manufacturing precision
If custom-fitted hearing devices are manufactured using manual labor, then manufacturing precision is improved, but productivity decreases
Solution Approach 1:
The patent changes the manufacturing parameters from manual craftsmanship to automated processes. By using digital 3D scanning to capture ear geometry and then employing automated manufacturing methods (such as injection molding or 3D printing) to produce hearing devices, the system maintains custom fit precision while dramatically increasing production efficiency. The digital parameters of the ear geometry guide the automated manufacturing process.
Solution Approach 2:
The patent replaces manual labor in the manufacturing process with automated systems. Instead of skilled workers manually crafting hearing devices to fit individual ears, the system uses automated manufacturing equipment guided by digital 3D models obtained from scanning. This substitution of mechanical manual operations with automated processes maintains precision while improving productivity.
