Designer Ma Yi Xuan's Double USB concept design is exactly how every USB plug should be, moving forward. No more shoving a USB cable into your computer the wrong way.

With the Double USB plug, Xuan's goal is to kill the frustration that would normally boil up whenever you plug a USB cable in the wrong way, only to have to flip it around.

It appears the head of the USB has two contact layers that can expand and contract freely. The first contact would connect with the port on a USB device while the second contact would be pushed inside of the plug, enabling universal pluggage. The design fix is so simple that we hope the Universal Promoter Group (people in charge of USB) take note for future USB reference designs.
