Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If soldering or conventional plug-in connecting systems are used for electrical connection between the electrical machine and control unit, then reliable electrical contact can be established, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The invention extracts the winding end from the electrical machine and guides it directly into the contact-making receiving opening in the control unit housing, eliminating the need for intermediate contact pins, sockets, or complex plug-in systems. This direct connection approach simplifies the overall connection system while maintaining reliability through the clamping mechanism.
Solution Approach 2:
The invention merges the mechanical connection and electrical connection functions into a single integrated structure. The housing with the contact-making receiving opening serves both as the mechanical mounting structure and as the electrical contact interface, eliminating the need for separate mechanical and electrical connection components.
2Reliability
If soldering is used for electrical connection, then reliable contact is achieved, but modular construction becomes impossible and manufacturing complexity increases
Solution Approach 1:
The invention enables modular construction by allowing the electrical machine and control unit to be manufactured as separate modules that can be independently produced and then easily assembled. The direct guidance of the winding end into the contact-making receiving opening, combined with the clamping mechanism, provides a connection method that is both reliable and suitable for modular assembly without requiring complex soldering processes.
Solution Approach 2:
The housing is pre-formed with the contact-making receiving opening during the control unit manufacturing process, and the winding end is prepared for direct insertion. This preliminary preparation of the connection interface enables quick and easy assembly of the modular components without requiring complex post-assembly operations like soldering.
3Ease of manufacture
If conventional plug-in connecting systems are used, then modular construction is enabled, but manufacturing cost increases
Solution Approach 1:
The invention uses simple, inexpensive components for the connection system - a housing with a formed receiving opening and a clamping mechanism - replacing expensive conventional plug-in connecting systems. The clamping part can be a simple deformable element or sliding component that provides reliable connection without the cost of complex multi-component plug-in systems.
