The birth of mechatronics?
A September 1929 article titled “Photo Cell in Sorting Machine Excels Human Eye” by Lester Ferenci describes how a cigar-sorting apparatus benefits from using a photo cell to sort stogies by color. The article starts with a prophetic statement: “More and more is electricity becoming a vital factor in machine design.” It then goes on to say: “We are beginning to realize the advantages to be gained by the use of electrical equipment in machinery and for this reason machine designers rapidly are familiarizing themselves with the functions of various electrical units, their principles and their possible utility in mechanics.”

Tips for streamlining design departments
John F. Hardecker, the chief draftsman of the U.S. naval aircraft factory, begins a six-part series outlining how to run a ship-shape design team. He finishes the article with some words on standardization: “In conclusion, while standardization has its faults and pitfalls, these best can be avoided by keeping constantly in mind the true meaning of standardization. The best definition known is that ‘standardization is common sense applied to creative individualism for the purpose of achieving the greatest good for all.’ Unfortunately, it is human nature to take a positive stand for or against on any new issue, but in standardization at least, the best position is a reasonable middle ground.”

How field testing and customers can improve designs
This November 1929 article describes how companies must continue field testing to prove their designs and manufacturing processes. But it also stresses that companies should use customer suggestions and complaints to improve their designs and resultant machinery. It even suggests being proactive and asking customers what could be improved or changed. The author, an unidentified Chapin Hoskins, says: “The machine which you have designed will, in the customer’s hands, be subjected to tests the most fertile brain could not possible think of in advance. After all, the worth of any machine is determined by what it does in practical use. For the actual test of practical operation by a customer there is no substitute.”
