Cause for Corrosive Action

Getting to gate 4, our group has had some issues. We try to work together to overcome these issues so our grades will not be affected. The members that work well together have decided to get most of the gate done before the due date. We are no longer waiting until the last minute which is improving our grade since we have extra time to look over things or ask questions. We are getting together on a regular basis and we do not leave until we have finished what we wanted to get done or if we know what our responsibilities are to finish. Most of the group members communicate frequently about the projects to see what has been done and what else needs to be done. If a member will not have enough time to finish their part then another member will help them out. For example, one group member was struggling to finish the three design revisions so another came up with an idea and helped get it done on time.

Product Reassembly

Step	Description	Image
1	For assembly of the gun, start with the empty frame with the orange barrel,manuever the chamber (indicated by the yellow box) into the frame, as is shown in the picture. Difficulty: 4 Tools used: Hands, Screw driver
2	Place the four trigger links into the frame (as in picture A) and place the trigger into the frame. Screw the components into place, indicated by the blue boxes (as in picture B), and connect the spring, indicated by the yellow box, to the component. Difficulty: Easy Tools used: Screw driver, hands	A)B)
3	Now, take the other frame and slide it into place. Then screw in the eleven screws into the frame, indicated by the blue boxes. Now you can put the butt cap, indicated by the green cap, onto the frame finally, take the two parts to the cocking handle and snap them in place and screw in the 5 screws, indicated by the orange boxes. Difficulty: Easy Tools used: Screw driver (screws), hands (removal of trigger components)
4	You now have a complete gun.
5	For assembly of the drum, start with the empty orange barrel. Now, place three springs (with orange Nerf caps) and place them in the barrels labelled 2, 3, and 4 (as shown in picture B). Difficulty: Hard Tools used: Screw driver (screws), hands (removal of chamber)	A)B)
6	Now take the orange cap to the barrel, compress the springs, and screw four screws on the cap, indicated by white boxes, into the barrel. Difficulty: Easy Tools used: Screw driver (screws), hands (removal of stem and caps)
7	Now you can see the components that make up the trigger for the reloading mechanism. Taking off the spring (indicated by the yellow box) lets the reloading trigger (indicated by the purple box) free. You can now take the trigger, spring, and rod (indicated by the blue box) off. Now, take out the 6 screws (indicated by the white boxes) and take off the black lid. Difficulty: Medium Tools used: Screw driver (screws), hands (removal of trigger, springs and rod) Removal of the springs and components of the reloding mechanism was easy, but very difficult to put back together because of the complexity of the placement of the simple components in order for the drum to be reloaded properly.
8	You should not have the components shown in pictures A and B.	A)B)
9	By taking out the 4 screws (indicated by the white boxes) on the orange lid, you will release the 3 other springs and spring caps. Your result should like look picture B. Difficulty: Easy Tools used: Screw driver (screws), hands (removal of lid, springs and caps) This process of removing the springs was simple due to the fact that the springs were only held by the lid and topped off by the cap. I do not believe the manufacturers intended for this to be neccessary because of all of the pieces you needed to take apart in order to get to this step.	A)B)
10	Once you remove the springs, you have an empty barrel and you can see the design that is intended to keep the disc bullets in place.

Mechanisms

Design Revisions

Add a battery powered motor to put energy into the spring instead of the hand operated cocking mechanism. This will make the gun easier to play with. Younger children and children with complications will be able to play with this nerf gun because it will only require them to pull the trigger to release the disc. There will no longer be a need for the outer cocking mechanism. This will be done inside the gun. The only thing the user will have to do now is turn on the battery by a switch. Once the switch is on, the gun will automatically reload and set the disc every time.
