Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connectors are used for programming hearing assistance devices, then electrical connection is achieved, but device volume increases and connection robustness is insufficient
Solution Approach 1:
The flexible tape connector is inserted into a slit opening formed by the housing and cover, nesting the connector within the device structure. This allows the connector to be housed compactly while maintaining multiple electrical contacts, resolving the contradiction between connection robustness and device volume.
Solution Approach 2:
The patent uses a flexible tape connector with multiple contacts instead of traditional rigid connectors. The flexible nature of the tape allows it to be compactly stored within the slit opening while providing multiple reliable electrical contacts when engaged, thereby improving connection robustness without increasing device volume.
2Reliability
If traditional programming connectors are used, then electrical connection is established, but the connection is not robust and reliable
Solution Approach 1:
The flexible tape connector provides multiple electrical contacts in a single flexible element, improving connection reliability without requiring complex multi-component connector structures. The flexibility allows the tape to conform to the contact surfaces, ensuring reliable electrical connection.
Solution Approach 2:
The connector is nested within the housing and cover structure, with the slit opening providing a defined insertion path. This integrated approach simplifies the overall connector structure while maintaining robust electrical connections through the flexible tape's multiple contacts.
3Volume of stationary object
If compact connectors are used to reduce device volume, then device size is reduced, but connection reliability may be compromised
Solution Approach 1:
The flexible tape connector maintains multiple electrical contacts in a compact form factor. The flexibility of the tape allows it to be inserted into the narrow slit opening while still providing sufficient contact pressure and multiple contact points, ensuring reliable connection without increasing device volume.
Solution Approach 2:
Instead of increasing connector size in one dimension to improve reliability, the patent uses a flexible tape with multiple contacts arranged along its length, distributing the connection function across multiple points. This maintains compact overall volume while achieving robust connection through the multi-contact approach.
