Forks, Phonographs, and Hot Air Balloons: A Field Guide to Inventive Thinking

by Robert J. Weber

How do inventions take shape? How did the inventors of the sewing needle, the hammer, or the wheel find their ideas? Are these creations the result of random events, or are hidden principles at work? Using everyday objects most of us take for granted--from forks and Velcro to safety pins and doorknobs--noted cognitive psychologist Robert Weber takes a fascinating look at how our world of inventions came into being, and how the mind's problem-solving...

Practical and Delightful

In most fields of endeavor, the people who understand how their tools work have an advantage over those who do not. The inventor's mind is obviously his or her most important tool and also the least understood tool. This author has spent years studying and analyzing inventing thinking. The author, Robert J. Weber, is Professor of Psychology at Oklahoma State University, but please note this book is free from the psychobabble some popular magazine articles use when claiming to analyze the invention process. He points out that while designing, engineering, and science also solve problems it is often the inventor who finds "the one good idea." He presents the classic example of the Wright brothers. By hands-on experimenting these two bicycle shop owners succeeded where Samuel Langley failed. Langley had vast resources at his disposal, but he fixed upon automatic control and a powerful motor as the solution. The Wright brothers believed in manual control (bicycles work, they are not stabilized automatically), wind tunnel testing to optimize wing and propeller shapes, and they built their own motor to fit their needs. In the author's words: "Langley represents big science at its worst." "The Wrights represent small science at its best." In analyzing Leonardo da Vinci's helicopter design the author notes how far ahead of its time it was. 400 years! He lacked a motor and some modern light weight materials. In contrast, looking at Edison's phonograph (l878) Weber notes that while it is often cited as totally unanticipated, it can be also be argued it could have been invented 20 years earlier. He gives a sketch of a similar device--Leo Scott's phonautograph of l857 which used a smoked drum to record sound waves. An interesting sidelight is the Montgolfier brothers who, in l783, achieved the first human flight by means of a hot air balloon. They "thought that burning straw would produce hydrogen." Not all of his examples are of famous inventors. An eight-grade Weekly Reader contest winner, James R. Wollin, produced a means for getting all the peanut butter out of the jar. He added a second lid to the bottom of the jar! He points out that Albert Einstein, Max Planck, and Jacob Rabinow (Post Office machine readers) all have commented that the creative process, at least in the early stages, is not a logical process. Throughout the book the author cites basic concepts that he has run across in analyzing inventions. For example, "parallelism." A one-tooth saw would be ridiculous. "Spatial transformation." Rotate an arch to generate a dome or repeat it to generate a corridor. Don't think of this book as 'old stuff.' He also takes us up to the present day with discussions of genetic engineering and "smart materials." (Materials that change properties in changing environments.) After reading this book you may never again look at a fork, safety pin, or knife as simple devices. Their evolution is fascinating and the concepts and principles of their e
