By spreading the forces on impact over a large area so that the force per unit area is reduced and no part of the product is subjected to concentrated forces
By supporting the product at its stronger points so that the forces on impact are directed to those points and not to the weaker ones
By reducing the forces and hence the deceleration on impact by using materials which compress on impact and cushion the product by absorbing the energy of the impact and converting the short duration/high intensity forces to lower intensity/longer duration forces which are less damaging
