Actually, modern interpretations of special relativity don't accept the
notion that mass increases with velocity. Rather, relativistic momentum
increases nonlinearly with velocity. If you define a "relativistic
mass" as momentum / velocity, you do get the result that this "mass"
increases with speed. But it is generally considered simpler to say
that momentum is not proportional to velocity and mass is constant.

Whichever formulation is used, conservation of momentum is the relevant
law. Your device is claimed to violate conservation of momentum, even
though each individual part observes this conservation law. This is
plainly impossible based on current physics.
