Hearing Device Earpiece Sensor Nesting and Pass-Through Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for earpieces for hearing devices that do not strain the user's ear while enabling continuous health data monitoring, as existing solutions often compromise comfort due to bulkiness and exposure of sensors to ear canal contaminants.
Innovation Solution
The earpiece design incorporates a housing with a pass-through area allowing a primary sensor to measure physiological parameters without increasing the volume, integrating the sensor with the receiver housing to minimize space usage and protect it from contaminants, using transparent materials to maintain signal quality and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the earpiece housing volume is increased to accommodate a primary sensor for health monitoring, then the sensor can be integrated inside the housing, but the earpiece becomes bulkier and may strain the user's ear
Solution Approach 1:
The primary sensor is positioned inside the first volume of the earpiece housing, nesting the sensor within the existing housing structure. The side wall comprises a first pass-through area that allows the sensor to transmit and receive signals through the housing wall, enabling health monitoring functionality without requiring additional external space.
2Measurement precision
If the primary sensor is exposed to measure physiological parameters directly in the ear canal, then measurement accuracy is improved, but the sensor becomes vulnerable to contaminants and damage
Solution Approach 1:
The side wall of the earpiece housing acts as an intermediary structure between the primary sensor and the ear canal environment. The side wall comprises a first pass-through area that allows optical or electromagnetic signals to pass through while physically protecting the primary sensor from direct exposure to contaminants, moisture, and mechanical damage in the ear canal.
3Object-generated harmful factors
If the earpiece housing fills out the ear canal diameter to prevent ambient noise, then noise isolation is improved, but the available volume for components is reduced
Solution Approach 1:
The earpiece housing is designed with specific local characteristics: the side wall comprises a first pass-through area positioned at a specific location to allow sensor signal transmission. This localized modification enables the sensor to function effectively while maintaining the overall noise-isolating structure of the housing that fills the ear canal diameter.
