How Sweet It Is: Basketball Engineering

Engineering and basketball go together as we begin the Sweet 16 games in the NCAA tournament, but just how has engineering affected the game?

History

Dr. James Naismith, the inventor of basketball.

Dr. James Naismith, the inventor of basketball.

In 1891, at Springfield College, Massachusetts, Dr. James Naismith, a thirty-year old physical education instructor, was encouraged to create an indoor, winter “athletic distraction.” Using two vegetable baskets, a soccer ball, nine men per team, and a ladder to retrieve the ball from the basket, the game of basketball came into existence. He never entertained the notion of patenting his new game because it was for recreational fun. “Basketball is just a game to play. It doesn’t need a coach… you don’t coach basketball, you just play it.” Despite his comment, in 1900 he became the basketball coach for the Jayhawks at the University of Kansas.

Between 1892 and 1894, formal rules were devised, an inflated leather, albeit occasionally lopsided, ball was invented, and backboards were designed so fans could not reach over and deflect the shots. On January 18, 1896, the first “experimental” college basketball game was played between the University of Iowa and the new University of Chicago. The final score: Chicago 15, Iowa 12.

Equipment

U.S. Patent 1,718,305 was granted to G.L. Pierce on June 25, 1929 for the "basketball."

U.S. Patent 1,718,305 was granted to G.L. Pierce on June 25, 1929 for the “basketball.”

The ball is considered the most important piece of equipment. The original basketball was patented in 1929 (see U.S. Patent 1,718,305). It was made of leather on the outside and butyl rubber on the inside. Zinc and cooper plates imprinted the label onto the ball. Wilson has developed the Solution which is the official basketball for the NCAA championships. The company’s patented composite-leather technology absorbs moisture for better ball handling.

In 1893, iron hoops and hammock-style enclosed baskets were introduced to the game. It was another decade before open-ended nets were used. In the 1930s a flurry of patents were filed suggesting that the game was becoming a viably commercial sport. The game continues to evolve with technology enhancements such as breakaway rims, vision replay, and performance shoes. If only Dr. Naismith could have foreseen the future of his fun “athletic distraction.”

The Wilson Sports Good Company is maker of the official basketball for the NCAA.  They hold a plethora of patents related to the basketball.   This includes United States Patent 4570931 which relates to the pebbled triangle design on the surface of the basketball.
