In a textile factory, changing the thread spindles when they ran out was a physically stressful job. It required a team of two--one pushing a cart with the fresh spindles, and the other constantly having to move the stool, climb up and replace the spindle, and climb down. The guy on the stool was often taking sick leave because of the physical demands, which sometimes led to falls and other injuries.
A factory worker observed this problem. In his own time after work, the factory worker began experimenting with how to propel the stool so that the worker didn't have to keep getting up and down. Eventually he had the idea to put wheels on the stool, and then he rigged up an electric motor to propel it. In a final ingenious flash, he adapted a sewing machine pedal to the mechanism so that the worker could stop and start it at will. The results? Less sick time, less injury, and greater efficiency and productivity.
Interesting moving work station design.
