-Bolts -Welds

-Steel and iron are most commonly used -Aluminum is much less commonly used

-Fittings -Concrete

-Wood is rarely used

“Bike rack can’t stay in the street permanently.”

“Past designs were too complicated to fabricate.”

“Gates should create a unique entrance for driveway.”

“Custom parts make projects impossible to maintain.”

- Dave Prendergrast

The incline brings the road even with the curb at 5’ Swinging mechanism must be positioned a few inches above curb to avoid contact with the street

Brainstorming & Sketching

Greensgrow Bike Rack

Modeling: First Iterations

Greensgrow Bike Rack

Problems Found -Bikes collided -If positioned incorrectly bikes went too far into street -Non-intuitive configuration

Greensgrow Bike Rack -Bikes collided -Takes up large amount of space when not in use -Angle of corner causes bikes to collide

Modeling: Second Iteration

Greensgrow Bike Rack

Pros:

Cons:

-Form held most bikes -Allowed for bikes to stay well within alotted space

-Hinge proved problematic due to complexity

Client Feedback ”Having the rack swing from two posts might be a good idea.”

Greensgrow Bike Rack

“Locking to posts should allow zero room for error.”

- Ryan & Dave

Revisions

Greensgrow Bike Rack

Pros:

Cons:

-Open design aids bike placement

-Bent T-shape may be difficult to fabricate

-Lack of top rail moves away from fence aesthetic

Full scale testing Testing proved that the T shape wasn’t able to safely hold a bike

Greensgrow Bike Rack

Conclusion:

A closed loop is ideal

Models A closed form would aid in securing a cyclist’s bike lock

Greensgrow Bike Rack

Goal:

Find a strong material suitable for creating a bent loop

Material Exploration

Greensgrow Bike Rack

Cut tests were conducted on different types of metal stock Steel rods proved to be the strongest

Threaded Rod

Aluminum Conduit

Steel pipe

Steel Rod (solid)

Material Exploration

Braided steel can be easily bent and assembled, and provides a sufficient amount of security for short-term bike parking

Design Revisited

Greensgrow Bike Rack

Working With Vendors With our simple design, we contacted a local waste management company, Revolution Recovery, in an attempt to gather material.

Greensgrow Bike Rack

Working With Vendors Straight metal tubing was not easily accessible Metal banquet chairs were cut apart and incorporated into our pre-existing designs involving braided cable.

Client Feedback

Greensgrow Bike Rack

”All exposed edges should be crimped and sanded.”

“This design would require heavy welding.”

Final Model

Greensgrow Bike Rack

This model utilizes readily available hardware and standard part sizes Vertical poles provide comfortable locking point
