Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single unified connection is used for all signal types and media, then the connection structure is simple, but it cannot provide different spatial orientations needed for different signals and media
Solution Approach 1:
The connector is divided into multiple separate connections (first connection for electrical signals, second connection for pneumatic/hydraulic media, third connection for optical signals) instead of a single unified connection. Each connection is optimized for its specific signal type and spatial orientation requirements, resolving the contradiction between adaptability and complexity by segmenting the connector into specialized sub-components.
Solution Approach 2:
The patent introduces spatial orientation as an additional dimension by arranging connections in different spatial directions (first connection in first orientation, second connection in second orientation, third connection in third orientation). This dimensional approach allows each connection type to have its optimal orientation without interfering with others, achieving adaptability while maintaining manageable complexity through structured spatial arrangement.
2Adaptability or versatility
If multiple connections with different spatial orientations are implemented, then different signal types and media can be connected optimally, but the manufacturing precision requirements increase
Solution Approach 1:
By segmenting the connector into separate connection components (first connection, second connection, third connection), each with its own spatial orientation, the patent reduces the overall manufacturing precision requirement. Instead of manufacturing one highly complex multi-oriented connection, multiple simpler specialized connections are manufactured separately and then assembled, reducing individual manufacturing precision demands while achieving the same spatial orientation capability.
Solution Approach 2:
The patent incorporates preliminary positioning features and alignment mechanisms in the connector design that guide the assembly process. These pre-designed alignment features reduce the precision requirements during final assembly by providing built-in guidance, allowing connections with different spatial orientations to be assembled with standard manufacturing tolerances rather than requiring high-precision manufacturing for each individual connection.
3Reliability
If a secure and tight connection is ensured, then reliability under environmental influences is improved, but the ease of operation for detachable connections is reduced
Solution Approach 1:
The connector is segmented into modular components that can be easily assembled and disassembled. Each connection type (electrical, pneumatic/hydraulic, optical) is designed as a separate module with its own sealing and locking mechanisms. This modular segmentation allows each module to provide secure tightness independently while maintaining overall ease of operation, as users can attach or detach individual modules without affecting other connections.
Solution Approach 2:
The connector incorporates self-sealing and self-locking mechanisms that automatically engage when components are connected. The sealing elements automatically position themselves to ensure tightness, and locking features automatically engage to secure the connection without requiring additional manual operations. This self-service approach maintains high reliability and tightness while preserving ease of operation, as the secure connection is achieved automatically upon attachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connector system provides a reliable mechanical hold, high tightness, and ease of management by decoupling connection demands, reducing stability requirements and facilitating secure sealing across different signal types, while allowing for compact installation and flexible arrangement.
Implementation Method 1
The connector contains an elastic seal which is deformed upon connection of the plug-in connection and closes the connection between plug and housing

AI summary
A connector-based link is suited to various signals and media for connecting a tube with a hearing instrument, which ensures a reliable mechanical hold, good connection and high tightness and in the process is easy to handle. This is achieved by a connector for a hearing instrument system including a housing which contains a number of connections, and a tube which contains a number of lines, which is embodied to detachably connect a number of lines of the tube to a number of connections of the housing, wherein the connections of the connector contain different spatial orientations. The fact that the connections each have a different spatial orientation brings about a mutual decoupling. As a result, the demands on dimensional stability of the various connections are advantageously reduced since the different connections are not closed in a shared, identical end position.
