我倒觉得真是个好主意,优点很多~目前好像已经申请了专利!
This isn't the first concept to use alternate hues to detect tread depth, with other ideas having already been patented. The patented Colored Wear Indicator for Tires uses not just one, but several colors to indicate how far the tread has worn down. The patent for a Vehicle Tire Tread Depth Determining System, conversely, doesn't use a fixed color, it uses an ultraviolet-sensitive layer that changes color after enough tread has worn down so that it is exposed to sunlight. We're sure there are more out there; point being that designers are already thinking about how we'll check our tires when the last car parts store closes for good... and we run out of pennies. |
