ORIGINAL DESIGN
The blue curved piece in the assembly show the rubber band that stretches across the speaker to secure it in place. The band is difficult to put on and take off and it is really easy to lose since it comes completely off of the assembly. The uncurved, unassembled rubber band is shown to the right. The part highlighted in red is where the speaker rests. It needs to be adapted to be accommodate the fastener that will replace the rubber band. The lower part of the assembly is where the speaker attaches to the handlebars. As shown below, there are 6 different pieces involved in this sub assembly, including the top clip, lower clip, 3 pieces of rubber for padding, a bolt, and a nut. By adapting these components we will reduce the number of parts which will reduce the number of parts and the time of assembly during the manufacturing stage, as well as the time during the assembly by the consumer. Instead of having to completely screw or unscrew a nut each time you want to dismount the speaker system, it can be just as secure, and more user-friendly by swapping out this fastener.

RE-DESIGN
The yellow piece in the assembled views below show how we changed the piece fastening the speaker to the speaker holder to be a clasp or clamp on a hinge with rubber or foam bumpers in order to cushion the speaker. The green part is the adapted speaker holder, which now features the stationary portion of the hinge as well as a hook or clasp that the clamp will come to rest in. To modify the bottom portion of the assembly, the top clip was replaced two hooks shown in red that will anchor the rubber gripper and attach to the speaker holder. The rubber grip shown in blue is elastic and stretchy. The grooves on the top will nestle in to the bottom of the new top clip in order to ensure a more stationary fit. The part protruding towards the left is a loop intended to be held by the more elongated hook ensuring that the grip does not separate from the rest of the structure. The rest of the grip contains holes that would act like the holes of a belt. The elastic material and large number of holes stretches to adapt to different sizes of handlebars, or could be used on another structure similar in shape. The other hook on the new top clip is used to secure these holes and therefore hold the speaker in place. Below the pictures of how the rubber grip would look in the assembly are screenshots of how the part would look laying flat, which may be the orientation in which the part would have to be prototyped.
