Cybertruck And Physical Contradiction

Here is a problem in TRIZ terms: The stiffness of pickup truck’s body-on-frame construction should be big enough to ensure the ability to safely transport heavy loads AND should be small enough to get lighter truck body-on-frame constraction with better ride quality and safety.

This physical contradiction was beautifully resolved: The proposed exoskeleton design does away with the need for internal longitudinal stiffening ribs and braces because the structural skin of the cybertruck does all the work. It makes cybertruck to safely transport heavy loads AND lighter with better ride quality and safety. The whole body now is a structurally stressed member. Separation in system principle has been applied?
