This concept would be manufactured to replace existing pistons to increase airflow into a naturally aspirated engines.
The inner section of the piston will move independently of the actual piston and be controlled by the rocking motion of the connecting rod. This dynamic motion of the inner piston would increase the volume of the cylinder on the down stroke, increasing air mass, and increasing compression on the up stroke therefor creating more horsepower. The advantage of this design is that it simply replaces the traditional pistons in an engine block therefor there is no need for retrofitting to obtain desired horsepower gains.
The intended market for this product is hotroders and street racers. It should be manufactured so it would be cheaper alternative to buying than a supercharger or tubro system. This idea could also be implemented by car manufactures to produce vehicles with more horsepower and smaller engines without using a supercharger or tubro system.

Wouldn't this increase cost and decrease the life of a piston? With more moving parts and the necessity of lubrication between the inner and outer piston, would the cost of doing this outweigh the benefit? To answer this, we need to quantify how much horsepower this will add to the engine and testing would need to be done on the lifetime of this modification.
I agree. While I'm not a mechanic I believe the system will oil it's self natively. This is taken from How Stuff Works, "The cylinder walls and piston-pin bearings are lubricated by oil fling dispersed by the rotating crankshaft." If you look at my drawings the inner system would also be oiled by this same process without a need to change the system.
