Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connection wires are extended to connect inductive element to circuit board without digging holes, then ease of manufacture is improved, but device complexity and cost increase
Solution Approach 1:
The connection structure is divided into multiple functional segments: supporting element for positioning, containing element for securing, connecting element for electrical connection, and locking element for fixation. This segmentation allows each component to perform its specific function efficiently without requiring complex integrated designs or destructive modifications to the circuit board.
Solution Approach 2:
The supporting element acts as an intermediary between the connection wire and the circuit board, providing a non-destructive mounting solution. The containing element further mediates by securing the connection wire in place, eliminating the need for holes in the circuit board while maintaining structural integrity and electrical connectivity.
2Ease of manufacture
If connection wires are extended to bypass circuit board holes, then ease of manufacture is improved, but power consumption increases
Solution Approach 1:
The invention changes the physical parameters of the connection path by using a supporting element to elevate and position the connection wire optimally. This reduces the wire length and resistance, thereby lowering power consumption while maintaining ease of manufacture through non-destructive assembly.
3Ease of manufacture
If connection wires are extended above circuit board, then ease of manufacture is improved, but electromagnetic interference increases
Solution Approach 1:
The containing element functions as a shielding structure that encloses the connection wire, acting as a flexible shell that protects against electromagnetic interference. This shielding approach reduces harmful electromagnetic radiation while maintaining the manufacturing simplicity of wire extension connections.
4Reliability
If holes are dug in circuit board for connection wires, then connection stability is improved, but manufacturing precision and time increase
Solution Approach 1:
The supporting element and containing element are pre-assembled with positioning features before being mounted to the circuit board. This preliminary action ensures proper alignment and stable connection without requiring precise hole drilling and wire insertion operations during final assembly, thereby improving both connection reliability and manufacturing efficiency.
