The double hull in oil tankers
Telescoping structures (umbrella handles, radio antennas, pointers)
Business analogies: a special exhibit for one designer inside a boutique store inside a big market
File structures in the Windows computer operating system (e.g., Chapter 10 is a file in the NewTRIZBook file, which is a file in the My Documents file, etc, )
Measuring cups or spoons
Stuffing a turkey with sausage, stuffing the sausage with chestnuts, etc.
