W-Scale / Luggage

All airlines have weight limit on luggage, so of course the travelers are concerned with the weight but have no means of knowing the exact weight of their luggage.
Since most travelers usually keep their luggage on the upright position, standing on the wheels, This W-Scale design integrates the weight scale with the wheels. The gravity pulls the “suspension system” cover down to obscure the green part of the wheels, and if no green part shows, it indicates that it is over the weight limit and better prepare to hand over the
greens. As long as some green part can be seen, the luggage is not overweight and can be fed more.
