Increased production of urine, decreased capacity of the bladder, or
problems with the detrusor or the parts of the nervous system that
interact with it.

Correct. See above.

> Can it be some problem in contracted/relaxed condition of bladder?

Yes. Problems with the detrusor can produce unusually frequent or
infrequent urination, up to and including incontinence and retention
leading to stagnation and infection. Problems with the nerves
interacting with the detrusor can have a similar effect.

Physical encroachment on the bladder (as during pregnancy) can reduce
its useful capacity and increase the frequency of urination.

Note that while some conditions may increase the _frequency_ of
urination, they may not necessarily increase the _volume_ of urine
excreted.
