Reversible Connector Assembly With Variable-Length Pins and Fewer Signals

The patent applies universality by making each signal pin capable of serving multiple functions. Specifically, each pin can transmit different signals depending on insertion direction - for example, a pin may transmit differential signal D+ during forward insertion and D- during reverse insertion. This multi-functionality eliminates the need for separate dedicated pins for each direction, thereby reducing total pin count while maintaining bidirectional capability.

The patent employs inversion by reversing the signal assignment logic between forward and reverse insertions. Instead of using different physical pins for different directions, the same physical pins are assigned opposite signal roles when insertion direction is reversed. This inversion strategy allows the connector to achieve bidirectional functionality with the same pin configuration, reducing complexity.

Each signal pin is designed to perform multiple functions by changing its electrical role based on insertion direction. For instance, pins that would traditionally be dedicated to specific functions in one direction are reconfigured to serve different functions when inserted in the opposite direction. This universal usage of pins reduces the total quantity needed compared to having separate dedicated pins for each function and direction.

The patent merges the signal transmission paths for forward and reverse insertions by using the same physical pins for both directions. Instead of having separate pin sets for each direction, the signal paths are combined such that the same pins carry different signals depending on orientation. This merging reduces pin quantity while maintaining full functionality.
