Improvements of Cat Eye Reflective Road Studs

Engineer Percy Shaw avoided falling off a cliff when she saw the light from a cat eye on her way home. This event inspired him, and then he invented the cat eye reflective road stud. At that time, the cat eye reflective road studs were made of glass.

He made a lot of cat eye reflective road studs. The head of the cat eye reflective road stud is made of smooth round glass, and the lower end is nailed into the road, which is nailed into a row to make the indicator light.

The invention of the cat eye reflective road stud was a great success. The next year, in 1934, Xiao registered the patent of the cat eye reflective road stud. In 2001, the cat eye reflective road stud was chosen as the greatest design of the 20th century. With the characteristics of “simple”, “practical” and “beautiful”, the cat eye reflective road stud is well deserved!

Later, the cat eye reflective road stud was improved. The new cat eye reflective road stud consists of four glass beads, which are embedded in a soft rubber vault. The placement of glass beads of cat eye reflective road stud is also specified: the two opposite sides face in opposite directions. After this transformation, it will be safer. When a vehicle passes through the vault, the rubber will shrink and the glass beads will fall below the cat eye reflective road stud.

In fact, the cat eye reflective road stud is not only safer, but also has the function of self-cleaning. After the rain, the base of the cat eye reflective road stud stores rain. When the vault is pressed down, the glass beads of the cat eye reflective road stud will soak in the rain and be washed to remove the dust. The reason is the same as tears washing the eyeballs.
