An innovation sandbox has 3 key characteristics: focus,
massive experimentation capacity and ultra- low cost of each additional experiment.
Wright brothers created two innovation sandboxes which were to play a
significant role in their experimentation journey from 1900 to 1903 leading to their historic flight on Dec 17, 1903. What were
these sandboxes? How did they build them? What role did they play in their
success? Let’s explore these questions in this article. I will refer to the well-made documentary film "Wright brothers' flying machine" (embedded above) for you to see it visually. I have put
the time in the film where the topic is discussed in brackets e.g. (11:18)
meaning 11 minutes and 18 seconds.
Sandbox-1: kitty-Hawk: Orville & Wilber Wright became serious
about attempting to build the flying machine in 1899. They knew they were entering into a serious game
where experimentation would last several years. In fact, one of the serious
players in the game, Otto Lilienthal had died in a crash during his flying
experiments in 1896 (11:18). Wright brothers did extensive study of available
literature. They had to work out all the 3 key sub-problems: lift, thrust and stability. However, their approach stood out for their focus on stability (16:11). For the other two problems, they
had good starting points e.g. the lift tables published by Lilienthal and the propellers used in ships.
Wright brothers had to work within two serious constraints: shortage
of money and ensuring safety. Following table shows how their experimentation
capacity increased hundred-fold in the 4 years. Cost of each experiment was pretty
low (29:55). Neither of the brothers suffered any injury due to a flight
accident throughout these experiments. Their sandbox was literally in the sand
dunes!
Sandbox-2: Wind-tunnel: While
Lilienthal’s lift tables were a good starting point; they turned out to be
inaccurate (12:15). What to do? Do you build a variety of gliders to derive a more
accurate table? That would have taken several years perhaps decades. Instead
Wright brothers built a wind-tunnel out of a wooden box in their Dayton workshop (13:15). It was 16 inches wide by 16 inches tall by 6 feet long. Their ingenuity
was in designing an intricate aerodynamic measuring device using an old hacksaw
blade and bicycle spoke wire. What could have taken years was achieved in three
months period. During October to
December 1901, Wright brothers re-generated lift and drag tables over 200
experiments. This helped solve the "lift" problem.
