What dual purpose does natural rubber serve in the design of the Cats Eye?
Answer
It allows the unit to retract under weight and facilitates the cleaning of the glass surface by tires
Natural rubber is a critical design element because it provides necessary flexibility. When the heavy weight of a vehicle strikes the unit, the rubber allows the device to retract slightly into the road surface, which prevents the glass prisms from being crushed. Furthermore, this movement is designed such that the tires passing over the rubber help clear away mud, dirt, and water, ensuring the reflective surface remains clean and effective for the next passing vehicle.
