Product designing often involves challenges of transferring mechanical motion between different parts of the product. A product can involve different types of motion like horizontal, vertical, radial, circular, see saw, spiral etc. The product designer’s community has to intelligently deal with parameters like space, cost optimization, strength, user comfort, look and feel etc.  A combination of parts and structure designed to perfection work in synchronization to achieve the desired motion.From movement of a ball pen’s tip to the to and fro motion of the switch’s actuator, there is enough science and wonder in exploring designing methods for all mechanical motions. The factor of easiness and simple working is always fulfilled too. How does it all happen? What is the magic? Have a look at some of the common yet unseen mechanics involved in transfer of motion from the brains of product designers.
