So was this a design problem with the batteries or an engineering one? Or both? Did the fact that they tried to pack the battery as tightly in as possible contribute to those flaws?

The phones that have nonfaulty batteries do not explode.

This was mainly a QC problem. Batteries were produced with an unusual rate of defects that resulted in internal short circuits. Cramming the battery in to the smallest space possible may have exacerbated those defects, but batteries for consumer applications should not be so fragile that moderate pressure on their shells causes them to explode.

Maybe the designed tolerances were too close. ie they design something that could not be reliably made.
