USB, one of the most emblematic and used ports today, has earned an essential place in the lives of all technology lovers. However, have you ever wondered why the original USB connector, Type A, only fits in one direction?
Ajay Bhatt, the creator of USB, shared in an interview with PCGamer (via Applesphere) the reasons behind this peculiar design choice.
Over the years, we’ve seen how Apple ports like Lightning and USB-C have embraced symmetry and reversibility, allowing cables to be plugged in any orientation. In contrast, the USB Type A connector seems to require two or even three tries to get right the first time.
Bhatt explained that the main reason behind the lack of reversibility of USB Type A was an economic issue. At the time, implementing a rounded port, similar to the current USB-C, would have increased costs significantly. This was due to the need to manufacture special cables that worked in both directions, which would have been a technical challenge and additional expense.
An idea that Apple didn’t like
This decision was not to Apple’s liking. The Cupertino company is known for sparing no expense when it comes to improving the user experience. For Apple, the convenience of a connector that can be inserted in any orientation outweighs any additional costs. This aligns with the company’s philosophy of offering high-quality products, even if that means a slightly higher price.
Over time, the technology industry has evolved and adopted reversibility in its port designs, following the path that Apple had advocated for years.
From its 30-pin connector on the first iPhones to the most recent USB-C, the Cupertino company has greatly influenced the direction the industry has taken in terms of connector design.
