The original Wankel design definitely has a lot of mechanical constraints compare to the reciprocating design. I am not sure if the Liquid Piston company put some thought into solving these other than curing the vexing apex oil seal problem by creating a reverse Wankel design. The original rotary also suffered from poor fuel efficiency and some argued the real reason was due to the strict emission standards.
