Around 1875, an eminent scientist, inventor, engineer and innovator, Alexander Graham Bell was conducting research on sound and how to transmit it. As part of this work, he studied the workings of the human ear, noting that the eardrum vibrated in response to sound
Improve long-distance communication between people
At its normal volume, the sound of human speech did not carry very far
Distance communication between people was finally achieved through developing a telephone receiver that contained a vibrating metal diaphragm People could now communicate over a distance because the sound volume of their speech was amplified by the telephone receiver that acted as a human ear
Being alert to the increasing needs of people can be the trigger for an innovative solution. As a result of the endeavors of Alexander Graham Bell, the telephone was invented
Copying Comment
Generalizing from a narrower observation or experience and then specializing from there to a narrower application in a different setting is the secret behind idea copying. Alexander Graham Bell associated more broadly from the capability of the human ear to vibrate to hear local sound and, in so doing, was able to copy and adapt a vibrating metal diaphragm that could hear remote human speech
