Background
Hooded sweatshirts, or “hoodies” are a popular item of clothing in today’s society. They keep the wearer warm when the weathers turns cold, and can be comfortably worn both indoors and outdoors. They come in a multitude of colors, styles, and designs, and range in quality from low to medium, so they usually are not particularly expensive either. To put it bluntly, almost everyone wears hoodies, especially college students. But no matter the style of the hoodie, they all have one thing in common: they have a drawstring in the hood.The drawstring can be used to pull the hood tighter around the wearer’s head or face to protect from cold weather, but is rarely used in such a manner. Usually, the drawstring is merely decorative. The ends of the drawstring remain visible even when not being used, and simply put, a hoodie that is missing its drawstring looks bad. It gives the clothing an impression of being worn out or old, because the holes used to run the drawstring through the hood are empty. And hoodies lose their drawstrings quite often. The reasons for the string being displaced vary, but the main culprit is the washing machine. The string gets wrapped around the center spindle of the washing machine as it spins, and is yanked out of the hood. Additionally, when the drawstring is removed from a hoodie, it is nearly impossible to reinsert it using traditional methods.
Frequently Asked Questions
Q. What is the bio-inspired component in your design?
A. Group 8 decides that the design of Re-Stringer would be based off the mouth of an Anaconda, the skull of which can be seen in the image below
Q. Why does Group 8 decide to apply 3D Printing for Re-Stringer construction?
A. 3D Printing is the recent, accessible technique to assemble simple. Also, there are 3D Printers located within Drexel University's The Innovation Studio, which are available to students without any payments.
Q. What are the components of Re-Stringer? What are they made from?
A. The device has 4 components: the outer clamp part, the inner clamp part, the hinge pin, and the extension rod. The clamp mechanism is made of PLA (polylactic acid) filament, the hinge pin and extension rod is made of steel wire and stainless steel, respectively.
Q. How can the device operate inside of sweatshirt's hood without snagging it?
A. The extension rod, which is connected to the tapered nose cone of the inner clamp part, establishes the passage for the Re-Stringer to restring the displaced drawstring throughout the hood
