LIQUID SUPPLYING DEVICE, SERVER DEVICE, AND VEHICLE
Document Type and Number:
Japanese Patent JP2021086015
Kind Code:
A
Abstract:
To present information in such a manner that it can be expected to attract attention.SOLUTION: A vehicle 10 includes two wheels at front and rear sides in a travel direction. On an outer circumferential face of at least one wheel (e.g., a rear wheel) out of these two wheels is provided a protruding structure where information functioning as an advertisement is expressed by text, a symbol or a diagram or the like. When liquid is supplied to a protrusion of this protruding structure while the vehicle 10 is traveling, the liquid-deposited protrusion comes in contact with a road surface while the wheels are rotating on the road surface. The portions of the road surface contacted by the protrusion are thereby wetted by the liquid, and the portions of the road surface not contacted by the protrusion (i.e., road surface portions which a recess has passed through) are not wetted by the liquid. Therefore, as the vehicle 10 travels on a road, there occurs a liquid-wetted portion and an unwetted portion on the surface of the road, and information that functions as an advertisement is represented by a difference in the presence of the liquid.SELECTED DRAWING: Figure 1
