We do not anticipate the dissection of the Nerf Pyragon to be a problematic procedure. The tools that we will need will be a Phillips head screwdriver, flat head screwdriver, and a rubber hammer. The Nerf gun is assembled with mostly Phillips screws so the Phillips head screwdriver will be the most needed tool we use. The flat head screwdriver will be helpful in prying apart the plastic gun and parts inside it. Also, the rubber hammer will be useful to aid in prying apart the plastic parts involved in our Nerf gun product. We predict it will take approximately three hours to dissect our product. This involves taking it apart and analyzing the parts inside of the product. We assumed about an hour for dis-assembly, an hour for analysis, and an hour to reassemble the gun. There are a few challenges we foresee in the dissection of our product.
The clip involved with our Nerf product appears to be the greatest challenge as far as complexity. The disc ammunition is loaded through a top opening into a designated chamber. Once the chamber is full a lever mechanism is used to rotate the chambers so the next one can be filled. This is repeated four times, and as the gun fires it rotates backwards to its original position. This means there are several locking and unlocking mechanisms involved with loading and firing, which means more dis assembly, analysis, and reassembly. The pump on the end of the gun performs several operations with one quick motion. When pumped a disc is chambered to be fired, the spring is compressed, and the trigger is primed. Because of the number of duties performed by this piece of the gun, the pump will require special attention. The trigger is challenging also because it performs more than one task. It simultaneously releases the spring to fire the disc, and readies the next disc to be fired. With special attention to the magazine, pump, and trigger our group should be able to overcome the more difficult concepts of the Nerf toy.
Group Capabilities Assessment
Each member of our group has their own capabilities to benefit the dissection of our product. Regardless of capabilities, each member also has shortcomings that may affect our work. The table below demonstrates these pros and cons.
- Capabilities: Previous experience with Nerf guns, technical writing skills, work with 3D modeling
- Shortcomings: Bad time management skills
- Capabilities: Good time management skills, leadership ability, communication skills, typing skills
- Shortcomings: Never owned a Nerf gun
- Capabilities: Previous experience with Nerf guns, had classes in physics and CAD
- Shortcomings: Hasty
- Capabilities: Previous experience with Nerf guns, has experience with CAD
- Shortcomings: Bad time management skills
To better manage the project we have assigned roles to each group member to lighten the work load and better organize the task. Rachel has been assigned Project Manager, due to her proficiency in leadership and time management. Peter has taken the Web Expert position, because he has previous experience with web programming. His position will require him to update the wiki when needed and handle other online research tasks. Brenden offered to take the Communication Liaison role, and will be relaying information from the group to the professors and the other way around. Ryan will be filling in the Tech Expert position, and will be revising and working on technical papers throughout the project.

Wednesdays at 5pm at group study area in the library. Sundays may be used as optional meeting times should we need more time or unseen complications arise. The following weekly schedule puts the group ahead of the current schedule, which means we can be better prepared for any emergency events that may come up during the course of the project.

In our initial assessment of our product, we familiarized ourselves with the product. This allowed us to gather information regarding our product to successfully complete our dissection. Our product was developed in the beginning of the year 2012. Key economic concerns were the price so it could be made into a cheap toy for the poor economy. Key global concerns were the safety of the product since it has real gun like features. The product was planned to be sold in North America and the UK. The toy is designed for the safe enjoyment for kids ages 8 and older. The Nerf gun is intended to be used at home and helps give young kids a fun and safe toy to play with. While being a children’s toy, the Nerf gun has some complexities. It uses mechanical work to turn potential spring energy into kinetic energy. The components consist of a clip, clip mechanisms, trigger, pump, jam release. Also this product has a complicated camber to hold the foam discs. The interactions between the components themselves are not too complex. It is made up of mostly plastic, with some metals screws and 40 foam discs. We believe that there are also metal springs inside the product. The complexity of this product makes it more enjoyable to play with. The simplicity of using the toy makes it easy for most users to pick it up and perform with it, often with very little previous knowledge about the product. The design is as intuitive as load, pump, and shoot. Since the design itself is simple, and most of the material being made of plastic, the Nerf weapon requires little to no maintenance throughout the course of its lifetime. Many of Nerf’s other products function in a similar fashion. Some guns offer advantages such as auto fire, while others have disadvantages such as smaller clip sizes. The price difference between products can vary depending on the complexity of toy, where the most complex Nerf gun is upwards of 150 dollars, and the simplest as low as four.
