The Design Team

The following four design members will be working together, using each others' strengths and weaknesses, and communicating effectively to reverse engineer the Nerf N-Strike Longstrike CS-6. The engineers working on this design team are:

                           Sarah Selk       [Project Manager]
                           Brianna Stewart  [Director of Communication]
                           Brian Heffernan  [Technician]
                           Bryan Krajewski  [Engineer]

The Product

The Nerf N-Strike Longstrike CS-6 has taken a traditional Nerf gun and transformed it into a three foot long, thirty-five foot long range, firing Nerf machine. The Nerf gun is intended for children ages six year and older. It consists of six main components, which are shipped in seven pieces, which must first be assembled in order for the gun to be used. The user must first cock the gun backward and then forward in order to load the foam Nerf dart into the base of the gun. When the trigger is pressed, the dart is released. To discover the inner workings behind this variant design is the goal of the design team's work. "So grab your gear, steel your nerves, and prepare to 'go long!' "[1]

The Product Proposal

The Nerf N-Strike Longstrike CS-6 was the right product for the design team. Each member has the right skills to work together to reverse engineer this product, as well as learn about factors that influenced the design. The mechanical components, the complex concerns behind the design, and the finances all form an important role in this project. All of this, the design team has chosen to figure out about the Nerf N-Strike Longstrike CS-6.

The Project Proposal

Gate 1: Project Planning

To reverse engineer the Nerf N-Strike Longstrike CS-6 is a time consuming task, that involves many parts and an extreme attention to details. Therefore the design team outlined the entire extent of their project with a time table as well as researched an initial assessment of the Nerf N-Strike Longstrike CS-6. This was done by the team as a whole in order to ensure completion of the entire project on time as well as to the best of their abilities. This was done to ensure a fully functioning and communicating design team.

*Gate 1: Project Planning

Gate 2: Product Dissection

The next step completed by this design team in their reverse engineer project was to fully dissect the Nerf N-Strike Longstrike CS-6. This process included the exact procedure taken by the team as well as an analysis of the connection between subsystems found. A brief review of the design team's functionality was also included.

*Gate 2: Product Dissection

Gate 3: Product Analysis

After dissecting the Nerf Longstrike CS-6 and documenting the process, a thorough engineering analysis was completed for the product. Components were classified and analyzed in order to fully understand the functioning of the Nerf gun.

*Gate 3: Product Analysis

Gate 4: Product Explanation

As the design team finished the analysis of the components of the Nerf N-Strike Longstrike CS-6, the next phase in their project was to reassemble the Nerf gun. As the product was returned to its original form, the design team fully analyzed the mechanism involved in the Nerf gun as well as recommended three design revisions which would increase the desirability of the Nerf gun.

*Gate 4: Product Explanation

Gate 5: Delivery

The final step of the design team’s reverse engineering project of the Nerf N-Strike Longstrike CS-6 was to finalize all of the work that the group completed throughout the project. The team revised all of their information as well as summarized their major findings from the project. The team completed the project as they gave a final assessment and an oral presentation.
