You're assuming of course that the board is designed first. However, I
think that the only consideration is the minimum area the board will need,
the rest is up to the designers. The biggest constraints are the screen
and battery, in my view. Battery lifetime depends on the size, so you have
to make a trade off between battery life and phone size.
Likewise for the screen, the designer will decide what screen size to use
based on what size device they want. Once you have an idea about the size
of the screen (and the whole phone) you then design the board to fit the
components and place them according to the desired button locations. The
shape of the board will depend on other components and where they need to
be.
All in all, I think that once the minimum size is known, the size of the
phone and it's shape is largely decided early on and the remaining
decisions about screen and battery are secondary (within the constraints
of course). I don't think any one thing is made and then everything else
fits around it. But rather, they have a general idea of what they want,
what the constraints are and what flexibility they have. So I don't think
the designed is derived from the functionality as much as you describe.
Certainly, certain decisions are forced due to the constraints, but I
believe that for the most part, the internal components are designed to
fit within the desired design.
Apple will have no doubt chosen a target size and shape and then found the
best way to fit everything together. This is probably why the size of the
phone is largely the same through various generations, they made a
decision that this is the ideal size, shape and screen size and they are
sticking to it.[ Reply to This | Parent | # ]
