The explosions and fire-catching "Galaxy Note7" unit is behind us with the battery being the obvious culprit behind Samsung's deficiency. "Instrumental," a company; specializing in engineering tools and services, has operated some of its teardown and upon closer inspection has a different take on the matter.
Meanwhile, "Instrumental" suggests Samsung was too aggressive in its internal design margins. This had left no room for the phone's battery focus. "Any battery engineer will tell you that it's necessary to leave some percentage of ceilings above the battery, 10 percent is a rough rule-of-thumb, and over time the battery will expand into that space," as stated by Instrumental.
"Samsung had a hard task for the Note7 to make a better battery life than its predecessor all the while having a slimmer design. The Note7's Li-Po battery is a "jelly-roll" model, which consists of a positive and a negative layer separated by polymer. It's what allows energy to flow between the two layers without them touching, because once that happens; the battery explodes due to the increased heat and greater energy transfer because of it," as explained by Instrumental.
The efforts "Samsung's Engineering Team" to conduct both safety and extreme boundary-pushing is remarkable. But, the efforts of the engineers to balance the risks of aggressive manufacturing and maximizing safety didn't lead to anything good.
"The design and validation process for a new product is challenging for everyone. In this case, Samsung took a deliberate step towards danger, and their existing test infrastructure and design validation process failed them. They shipped a dangerous product. That this is possible at one of the top consumer electronics companies in the world is humbling -- and demonstrates the need for better tools. Instrumental is building them," as Instrumental closes the discussion.
Samsung acquired a big damage in terms of revenue. By one calculation, the company will tally more than $5 billion in lost revenue and other costs associated with the recall of the "Galaxy Note 7."
