Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If USB 3.0 connector uses two rows of terminals to achieve higher transmission speed, then transmission speed is improved, but device complexity increases and manufacturing becomes difficult
Solution Approach 1:
The connector is divided into two separate components: an insulating housing containing first terminals and a mounting bracket containing second terminals. This segmentation allows each component to be manufactured independently with simpler structures, while still achieving USB 3.0 functionality when assembled together.
Solution Approach 2:
The patent transitions from a single-plane terminal arrangement to a multi-dimensional structure where terminals are distributed across two separate components (housing and bracket) that assemble together. This dimensional change enables simplified individual component designs while maintaining the required two-row terminal configuration for USB 3.0 speed.
2Speed
If USB 3.0 connector uses two rows of terminals to achieve higher transmission speed, then transmission speed is improved, but connector size increases making it longer and broader
Solution Approach 1:
By splitting the terminal rows into two separate components (insulating housing with first terminals and mounting bracket with second terminals), the overall connector length is reduced. Each component can be compactly designed, and their assembly creates a more space-efficient structure compared to a single-component two-row design.
3Speed
If USB 3.0 connector uses two rows of terminals to achieve higher transmission speed, then transmission speed is improved, but crosstalk occurs between terminals interfering with signal transmission
Solution Approach 1:
Dividing terminals into two separate components (first terminals in insulating housing, second terminals in mounting bracket) physically separates signal paths, reducing electromagnetic coupling and crosstalk between adjacent terminals while maintaining high-speed signal integrity.
Solution Approach 2:
The insulating housing and mounting bracket act as intermediary structures that provide physical separation and electrical isolation between terminals. These intermediary components prevent direct electromagnetic interference between signal lines, reducing crosstalk.
4Speed
If USB 3.0 connector uses two rows of terminals to achieve higher transmission speed, then transmission speed is improved, but production rate decreases and manufacturing cost increases
Solution Approach 1:
Manufacturing the insulating housing and mounting bracket as separate components allows for independent production using optimized processes for each part. This segmentation enables parallel manufacturing, simplifies assembly, and improves overall production rate compared to manufacturing a single complex two-row connector structure.
Solution Approach 2:
The patent changes the manufacturing approach from single-component fabrication to multi-component assembly. This parameter change in the manufacturing process enables simpler, more efficient production methods for each component, thereby increasing production rate and reducing costs while maintaining USB 3.0 performance.

AI summary
A crosstalk-proof plug connector has an insulating housing, a mounting bracket, multiple first terminals, multiple second terminals and a shell. The first terminals are mounted on the insulating housing. The second terminals are mounted on the mounting bracket. Each terminal has a mounting section, a soldering section and a contacting section. The soldering sections are arranged in a transverse row with a specific sequence to prevent crosstalk interfering with signal transmission.
