“Can we remove the effect of weight?”
Anti-weight: To compensate for the weight of an object, add buoyancy or lift.
Buoyancy is one method to compensate for the weight of the object, wherein the weight of the object is offset by merging it with something else that can provide lift.
Examples include floating a boat with foam-filled pontoons, lifting a basket with a hot air balloon, and the buoyancy tanks in submarines. In each case, the overall density of the object is reduced by adding very low density chambers, making the object float in air or water.
Another method to oppose the weight of an object is to make it interact with the fluid it operates in, be it air or water. This includes wings on planes, hydrofoils on ships, magnetic levitation of bullet trains etc.
Another approach to applying anti-weight is to examine lateral forces, rather than just vertical. An example of this is the efforts by car designers to resist the natural roll of the car body when entering a turn using either anti-sway bars or active dampers.
Many automotive trunk lids, hoods, and hatches rely on some pressurized strut or spring to reduce the weight
Surface tension is another anti-weight approach, such as a leaf or an insect resting on the surface of the water.
As I stumble across real world examples of this Inventive Principle in action I add them here.
What problems do you face that this inventive principle could help solve? Have you used this principle before?
