Early Sketches
Proof that the first design is the worst design. These models did not pass the tipping requirement or would've had to be too bulky to save space. The free standing A-frame design was analyzed in fall quarter of 2014. It turned out that the feet would need to be close to 4ft long to satisfy the stability requirement.
Final Sketch
Having to set aside 40 hours of work and start fresh is hard for anyone. Without the free standing function this streamlined solution became clear. This design leans against a wall and contains a single post verticle member. There are two legs that are angled at 45 degrees from the wall and from the center post. The angeled legs create a force normal to the wall, keeping it from slipping.
Design
In the design phase many hours were spent brainstorming. Initialy, sketches were for a free standing rack. After many hours of static analysis it became clear that the free standing design was unsteady. A wall leaning rack presented itself as a solution that would save space and be very stable.
