Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fans use welded wires with predetermined or long length to connect to external systems, then the fan can be electrically connected to external systems, but the excess length of wires causes interference with other components or parts, decreasing reliability
Solution Approach 1:
The patent extracts the problematic excess wire length from the system by using a plug with integrated connecting portions that directly connect to the fan frame. The bipolar knife-shaped terminal is positioned between the connecting portions, eliminating the need for long welded wires that cause interference with other components.
Solution Approach 2:
The patent merges the electrical connection function directly into the fan frame structure by integrating the plug with connecting portions that attach to fixed holes in the fan frame. This combination eliminates the separate wire component that causes interference, while maintaining electrical connectivity through the integrated design.
2Measurement precision
If conventional fans use long welded wires for connection, then electrical connection to external systems is achieved, but the connection precision and reliability are reduced due to wire interference
Solution Approach 1:
The patent removes the intermediate wire component that prevents precise connection. The plug with connecting portions directly attaches to the fan frame at fixed holes, eliminating the wire's unpredictable positioning and interference that compromise connection precision and reliability.
Solution Approach 2:
The patent introduces a plug as an intermediary component between the fan frame and external systems. This mediator provides precise connection points through connecting portions that attach to fixed holes, replacing the unreliable long wires while maintaining electrical connectivity.
3Ease of operation
If conventional fans use welded wires with excess length, then flexibility in connection is provided, but interference with other components decreases system reliability
Solution Approach 1:
The patent extracts the excess wire length that causes interference while preserving connection flexibility through the plug design. The connecting portions of the plug can be positioned at optimal locations on the fan frame, providing flexibility without the harmful excess length that compromises reliability.
