Explanation:

To design a machine to remove the "squeak" from new shoes, we can consider a device that applies a lubricant (like oil or wax) to the areas of the shoe where friction causes the squeak (e.g., between the sole and the upper, or at the hinges of buckles). The machine could have a mechanism to hold the shoe securely, a reservoir for the lubricant, and a dispensing system (like a brush or a spray) that targets the squeaky parts. When the shoe is placed in the machine, the dispensing system applies the lubricant precisely, reducing friction and thus eliminating the squeak. The machine works by addressing the root cause of the squeak, which is friction between moving or contacting parts of the shoe.

Answer:

A proposed machine for removing shoe squeaks would hold the shoe, dispense lubricant (e.g., oil/wax) to friction - prone areas (sole - upper interface, buckle hinges, etc.) via a brush/spray, reducing friction to eliminate the squeak.
