Hearing Device Magnetic Fixation for Reliable Skin Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing devices, particularly behind-the-ear (BTE) and receiver-in-the-ear (RITE) types, face challenges in maintaining sufficient skin contact for sensor elements due to issues with adhesives, clamps, and springs, which can cause allergic reactions, skin pinching, and require multiple size options.
Innovation Solution
A hearing device with a housing configuration that uses magnetic or magnetizable attachment parts positioned on opposing sides of the pinna, utilizing attraction members like permanent magnets or electromagnets to provide consistent skin contact without mechanical connections, allowing for adjustable attraction forces and user-specific control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesives are used to attach sensor elements to skin, then attachment is achieved, but allergic reactions and skin irritation occur over time
Solution Approach 1:
The patent replaces chemical adhesives with a magnetic attachment system. Attraction members (magnets) are positioned on the hearing device housing to create magnetic attraction forces that hold the device against the skin without chemical contact, eliminating adhesive-related allergic reactions while maintaining secure attachment.
Solution Approach 2:
The patent changes the attachment mechanism from chemical bonding to magnetic force application. By adjusting magnetic strength and positioning, the system achieves reliable skin contact through physical attraction rather than chemical adhesion, avoiding the harmful effects of prolonged adhesive exposure.
2Reliability
If clamps or springs are used to maintain skin contact, then sufficient pressure is applied, but skin pinching and abrasion occur
Solution Approach 1:
The patent replaces mechanical clamps and springs with a magnetic field-based attachment system. The magnetic attraction provides consistent pressure to maintain sensor-skin contact without the pinching and abrasion caused by rigid mechanical components, distributing force more evenly across the contact area.
3Adaptability or versatility
If multiple clamp sizes are stocked for different users, then adaptability to various ear sizes is achieved, but device complexity and selection difficulty increase
Solution Approach 1:
The patent implements a universal magnetic attachment system where the strength and distribution of magnetic attraction can accommodate various ear sizes and shapes without requiring multiple physical device variants. The magnetic field naturally adapts to different geometries, eliminating the need for professionals to stock and select from multiple clamp sizes.
4Stability of the object's composition
If mechanical connections are used between attachment parts, then structural stability is achieved, but handling difficulty increases
Solution Approach 1:
The patent replaces mechanical connections (screws, clips, or latches) between attachment parts with magnetic coupling. The attraction members create a self-aligning, tool-free assembly process where parts are simply brought together and held by magnetic force, significantly improving ease of handling and assembly while maintaining structural stability during use.
