Abstract

A hollow quadrilateral prism consists of four rigid right triangular prisms laid asymmetrically in a V-like shape. Each triangular prism has a base face which is an obtuse scalene triangle, and the front and rear lateral faces are covered with a reflective material of visible light. The front and rear lateral faces of the four right triangular prisms face each other forming an asymmetrical channel between them, which is filled with a transparent material. The hollow quadrilateral prism reflects incident light in sequence by the reflective lateral faces of right triangular prisms. It is configured to make a good portion of the frame invisible to the driver of an automobile and renders driving safer and more comfortable.
