Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables extend from each fan for electrical coupling, then electrical connection is achieved, but the risk for cable damage increases and cable management becomes complex
Solution Approach 1:
The patent combines the electrical connection function directly into the mechanical coupling interface. The connector assembly integrates electrical contacts with the structural coupling mechanism, eliminating separate cables. When fans are stacked, the connector assemblies automatically engage both mechanical and electrical connections simultaneously, resolving the contradiction by merging two previously separate functions into one integrated component.
Solution Approach 2:
The patent extracts the cable component entirely from the system by implementing direct electrical contacts through the connector assembly. The electrical connection is achieved through contacts that engage when fans are mechanically stacked, removing cables from the system and eliminating the associated damage risks and management complexity while maintaining reliable electrical connectivity.
2Ease of manufacture
If snap fit connections are used to fasten fans together, then assembly is simple, but the connection loosens over extended use leading to loose electrical coupling
Solution Approach 1:
The connector assembly employs a dynamic locking mechanism that evolves during assembly. The connector initially guides alignment, then engages a locking feature that secures the connection. This dynamic progression from alignment to locked engagement maintains simplicity while ensuring stable, long-lasting connections that prevent loosening over extended use.
Solution Approach 2:
The connector assembly incorporates preliminary alignment features that guide the stacking process before final engagement. These preliminary features ensure proper positioning and prevent misalignment, enabling simple assembly while establishing a stable, pre-configured connection that resists loosening during extended operation.
3Reliability
If tidied-up cables are used for connection, then electrical coupling is achieved, but installation time increases and additional footprint is required
Solution Approach 1:
The patent merges electrical connection with mechanical stacking into a single simultaneous action. The connector assembly integrates electrical contacts with the structural coupling mechanism, so that when fans are stacked, both mechanical and electrical connections are established at the same time. This eliminates the separate step of cable management, reducing installation time while maintaining reliable electrical coupling.
Solution Approach 2:
The patent extracts cables entirely from the system by implementing direct electrical contacts through the connector assembly. Electrical connection is achieved through contacts that engage when fans are mechanically stacked, removing the time-consuming cable management process and reducing installation footprint while maintaining reliable electrical connectivity.
4Stability of the object's composition
If additional mechanisms are added to secure snap fit connections, then connection stability improves, but device complexity increases and installation time increases
Solution Approach 1:
The connector assembly merges the stabilization function with the primary coupling mechanism. The same connector that joins fans together also provides locking and alignment features, eliminating the need for separate stabilization mechanisms. This integration maintains connection stability while avoiding the complexity and additional installation time that would result from adding separate securing mechanisms.
