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

Project: Fire Fighter

The objectives of every design project can be divided to 5 major stepsa) Designb) Developc) Buildd) Teste) Market

Mission Objectives

Assembly Constraints1. Fits easily into egg2. No use of glue or tape3. More than 50% by mass 3D printed plastic

Mechanical Constraints1. Assembles Easily2. Energy Storage3. Move a minimum of 2.5 meters

Assembly Constraints

EffectiveMeet all design constraints

SimpleCreate a design that has the simplest possible

components and mechanismsMarketable

A design that we ourselves would enjoy

Team Vision

Four basic ideas for moving mechanism

Design Iterations

Introducing

Fire Fighter:

The Monster Tank

Product Design

Elastic mechanism winds axle 1. Attach one end of the rubber band to a hook2. Attach the other end of the rubber band to the

front axle3. Rewind the front axle4. Set it up on the table, and release

Moving Mechanism

Safe ComponentsRubber band is used for the mechanism which

is safe to useSprings for the missile is not strong enough to

cause physical harmNon toxic parts

RestrictionsNot for children under 6Small parts: choking hazard for infants and

toddlers
