Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If connectors are made compact in size and height by reducing pitch between terminals or downsizing components, then miniaturization is achieved, but durability becomes more difficult to ensure
Solution Approach 1:
The shielding part includes a curved portion at its upper end that curves inward in the transverse direction, forming an inclined portion. This curved configuration prevents warpage of the shielding part while maintaining compact connector dimensions, thereby preserving durability in miniaturized connectors
2Object-affected harmful factors
If shielding part is designed to block electromagnetic waves and noise, then RF characteristics are improved, but connector size increases
Solution Approach 1:
The curved portion at the upper end of the shielding part forms an inclined portion that blocks electromagnetic waves and noise effectively. The curvature allows the shielding part to maintain compact size while providing sufficient shielding coverage, preventing electromagnetic interference without increasing connector dimensions
3Object-affected harmful factors
If curved portion of shielding part is positioned too high, then shielding effectiveness is improved, but it interferes with connection between terminals of plug and socket connectors
Solution Approach 1:
The curved portion curves inward to form an inclined portion that is positioned at a height preventing interference with terminal connection. The curvature geometry is specifically designed to maintain shielding effectiveness while ensuring the upper end does not obstruct the mating process between plug and socket connectors
4Reliability
If shielding part is made rigid to prevent warpage, then durability is improved, but manufacturing complexity increases
Solution Approach 1:
The curved portion at the upper end of the shielding part provides structural rigidity to prevent warpage. The curvature itself acts as a strengthening feature that maintains durability without requiring additional complex structural elements or manufacturing processes
