You're missing a point. The helmet needed to build a new warframe is a different one from the ones you can "equip".

You should get the chassis, systems and the helmet dropped from bosses blueprints.

Example: If you wanna build a Volt, you should get the 3 blueprints (chassis, systems and helmet) from J3-Golem, located in Themisto - Jupiter.
