The Monster Tank

Brief Overview: - Objectives and Constraints - Design Process - Final Design: The Monster Tank - Safety Considerations - Marketing and Production

The objectives of every design project can be divided to 5 major steps a) Design b) Develop c) Build d) Test e) Market

Assembly Constraints 1. Fits easily into egg 2. No use of glue or tape 3. More than 50% by mass 3D printed plastic Mechanical Constraints 1. Assembles Easily 2. Energy Storage 3. Move a minimum of 2.5 meters

Effective Meet all design constraints Simple Create a design that has the simplest possible components and mechanisms Marketable A design that we ourselves would enjoy

Four basic ideas for moving mechanism

Elastic mechanism winds axle 1. Attach one end of the rubber band to a hook 2. Attach the other end of the rubber band to the front axle 3. Rewind the front axle 4. Set it up on the table, and release

Safe Components Rubber band is used for the mechanism which is safe to use Springs for the missile is not strong enough to cause physical harm Non toxic parts Restrictions Not for children under 6 Small parts: choking hazard for infants and toddlers

Project cost for units – 130,000$ Only 1.3 dollars per unit

Design Appeal Toy encourages spatial understanding/construction Violent toys dominate sales market Top of tank can be switched out: customizable Marketing Media Promotional animation video Brochures Website
