Solution Overview
Problem
Hearing instruments face challenges in size and cost due to the need for dedicated magnets to couple with charging cases, which occupy space and increase costs, while also limiting the inclusion of additional components like sensors or larger batteries.
Innovation Solution
Incorporating magnetic components that perform dual functions, such as coils, magnetic shields, cross-pins, and batteries, which can magnetically couple with a retention magnet in the case, eliminating the need for a dedicated permanent magnet, thus allowing for reduced size or increased battery capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated permanent magnet is used to couple the hearing instrument to the case, then the coupling reliability is improved, but the device size and cost increase
Solution Approach 1:
The patent applies multi-functionality by making existing magnetic components (coil, magnetic shield, cross-pin, battery, or charging contact) serve dual purposes: their primary function and coupling with the case via magnetic interaction with the retention magnet. This eliminates the need for a dedicated permanent magnet while maintaining coupling reliability.
2Reliability
If a dedicated permanent magnet is used to couple the hearing instrument to the case, then the coupling reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent reduces manufacturing cost by eliminating the dedicated permanent magnet component. Instead, it utilizes existing magnetic components that already possess magnetic properties to perform the coupling function, thereby reducing part count and assembly complexity while maintaining reliable coupling.
3Adaptability or versatility
If a dedicated permanent magnet is used for coupling, then the coupling function is achieved, but the battery capacity or additional components cannot be included
Solution Approach 1:
By making existing components multi-functional, the patent frees up device volume that would have been occupied by a dedicated permanent magnet. This additional space can then be allocated to increase battery capacity or accommodate additional components like sensors, thereby improving adaptability and versatility.
