Can You Solve It? The Forgotten Netherlands Creation That Shaped our Contemporary World
One can find numerous candidates for the title of “world’s greatest innovation.” The circular axle. The movable type. The steam engine.
As per a recent publication, however, that honor belongs to a automated sawmill conceived by Dutch inventor Cornelis Corneliszoon during 1593.
“Before mechanised cutting, building a simple merchant vessel necessitated around 10 lumberjacks working for three months,” notes the author. “With wind-driven sawmills, an identical amount of processed timber might be produced in less than seven days.”
Thanks to their rapid mechanical saw, which converted logs to boards using virtually no manual labor, Dutch builders could construct ships faster than anyone else, an advantage that sparked one hundred years of Netherlands naval, financial and artistic dominance in Europe and the world.
The Original True Manufacturing Device
The inventor's lumber mill, contends Dávila, represented “humanity’s initial authentic factory apparatus.” A windmill rotated a gear. A single part transformed its rotary motion to vertical action for the cutting blade. Another component transformed that same rotary movement into a lateral movement advancing the log toward the blade. A ratchet system shifted the log forward a measured step each cycle.
“Each element was simple by itself. Corneliszoon’s genius lay in how to combine them so the machine operated in a perfectly controlled sequence, cutting on every descending stroke while moving on every upward motion. This constituted an astonishingly clever use of basic parts.”
A fact that leads us up to today’s challenge. I’d like for you to reimagine a key the basic concepts underpinning this historic machine.
Round and Up
Construct a mechanism that turns rotary movement into up-and-down motion. You have these items only: A rotating disc. Two pins. Two rods. A “guide”, that is a tube or sleeve through which one of the rods will fit perfectly. (Assume you can put things on a stand, so that the parts don’t fall down.)
The solution returns at 5pm UK with the answer.
Meanwhile, PLEASE NO HINTS. Rather, please propose (non obvious) candidates for the planet’s most impactful invention.
