You probably didn’t think that one of the main reasons to choose a curly cord over straight is in its inherent durability. Coiled cords are meant to be able to be extended and retracted hundreds of thousands of times without breaking. This durability places them on the front lines of some really vital applications like with first responders, military, and industrial production. Next, curly cords afford a space-saving design. With the increasing complexity of today's electrical systems, space constraints require parts that can be utilized efficiently while taking up the least amount of space possible. Lastly, curly cords provide efficiency and organization in design because they can carry many different types of signal simultaneously - like power and data within the same system. This saves space in a tight environment and makes the transmission of data and/or electricity far more efficient than having multiple cables.
