Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of hearing devices requires reducing the dimension of connector systems without introducing additional adapters or connectors, which is hindered by the logistical and cost challenges of existing cable and connector systems.
Innovation Solution
Integration of a CS44 connector into the hearing device's supporting structure using a polymer plate with embedded electrical contact pins, replacing the traditional socket-like connector with a contact pin holder that is integral within the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional socket-like connector is used in the hearing device, then the connector provides reliable electrical connection and mechanical support, but the hearing device dimensions increase
Solution Approach 1:
The patent merges the connector housing and support structure into a single integrated component. The connector housing serves dual functions as both the electrical connection structure and the mechanical support element, eliminating the need for separate socket housing and reducing overall device volume while maintaining connection reliability
Solution Approach 2:
The integrated connector housing performs multiple functions simultaneously: providing electrical connection through embedded contacts, offering mechanical support and positioning, enabling cable attachment, and serving as a structural element of the hearing device. This multi-functionality reduces the number of separate components needed
2Volume of moving object
If a new programming cable system is introduced, then the hearing device can be miniaturized with optimized connectors, but logistic efforts and costs increase due to existing cable systems being widespread
Solution Approach 1:
The connector housing is designed to be compatible with existing programming cable systems while enabling miniaturization. By making the connector housing itself the interface standard rather than requiring separate adapters, the system maintains compatibility with widespread cables while achieving compact dimensions
Solution Approach 2:
Instead of adapting existing cable connectors to fit larger hearing devices, the patent inverts the approach by making the hearing device connector the standardized element that existing cables can interface with, potentially through direct connection or minimal adaptation
3Ease of manufacture
If a separate socket housing is used for the connector, then the connector provides mechanical support and orientation, but manufacturing complexity and production costs increase
Solution Approach 1:
The connector housing and support structure are combined into a single molded component. The housing integrates electrical contacts, mechanical support features, and structural elements into one piece, reducing the number of assembly steps and manufacturing operations required
Solution Approach 2:
The connector housing is designed with optimized geometric parameters and integrated features that allow it to perform multiple functions with a single component. The structure incorporates embedded contacts, positioning features, and mounting elements with specific dimensional parameters that enable both miniaturization and simplified manufacturing
