Ve yesterday's article I stopped at the quality of cables from Apple, especially their durability and resistance. One of our readers pointed to an older article from 2011 where an alleged Apple engineer on Reddit.com explains the design change for iPhone and iPod USB cables.

After 2007, Apple changed the appearance of cables, on the one hand, the 30-pin connector became smaller, another change was also noticed just below the connector, it turns into the cable, i.e. at the place where cables are now destroyed most often. Here, the company has turned a perfectly functional design into one that is the cause of many broken cables. Here are the words of an Apple employee:

I used to work for Apple and was in contact with all divisions of the company, so I know exactly what happened. It has nothing to do with trying to force customers to buy more replacement adapters, but more with the power hierarchy at Apple.

But before I get to that, I'll explain the engineering side of power cables. If you look at the charging cables of any non-Apple product, you'll notice plastic "rings" where the connector goes into the cable. These rings are called strain relief sleeves. Their purpose is to protect the cable from bending into sharp angles if you bend the cable at the connector. The cable strain relief sleeve allows it to have a nice, slight curve instead of bending to a 90° angle. Thanks to this, the cable is protected from breaking during frequent use.

And now to the power hierarchy at Apple. Like any other company, Apple consists of many divisions (sales, marketing, customer service, etc.). The most powerful division in Apple is Industrial Design. For those unfamiliar with the term "Industrial Design", this is the division that decides the overall look and feel of Apple products. And when I say "most powerful," I mean their decisions trump those of any other division at Apple, including engineering and customer service.

What happened here is that the industrial design department hates the way the strain relief sleeve on the charging cable looks. They would much rather have a clean transition between the cable and the connector. It looks better from an aesthetic point of view, but from an engineer's point of view, it's suicide in terms of reliability. Since there is no sleeve, the cables fail in a big way because they bend at extreme angles. I'm sure the engineering division gave every possible reason why the power cable sleeve should be there, and customer service communicated how bad the user experience would be if a lot of the cables were destroyed because of it, but industrial design doesn't like the strain relief sleeve , therefore it was removed.

Does this sound familiar? A similar decision caused a pseudo-case known as "Antennagate", where the iPhone 4 lost signal when held in a certain way, as the hand acted as a conductor between two antennas, which were represented by a steel band around the perimeter of the iPhone divided by spaces. In the end, Apple had to call a special press conference to announce that iPhone 4 users would get a free case. Apple engineers were aware of this problem before launch and designed a clear coating that would partially prevent signal loss. But Jony Ive felt that it would "adversely affect the specific appearance of the brushed metal." So nothing was done about the problem. You probably know how he escalated after that...
