The pink engineering pieces don't solve the princess problem. It does bypass it. A young girl who has learned in her schools social circles that girls only play with cute 'girly' looking toys that are pink (gender roles enforced in our society), would more likely agree to play with these 'feminine' engineering toys. This is a good attempt at targeting parents who are rigid and scared of shaking gender norms.
