INTRODUCTION
The Angel Wings Bike Seat is a unique two padded bike seat that moves with the rider.
When a bike user rides a bike for over 20 minutes on a traditional bicycle seat, he or she starts to experience discomfort.
The Angel Wings Bike Seat is the only two padded bike seat that moves with the rider’s body.
The patented seat supports the torso with the first pad moving forward while the other moves backwards on the down pedal stroke.
PROBLEM STATEMENT
The initial problem is that the Angel Wings Bike Seat is not ready for launch.
Final component designs need to be made. Requests for manufacturing quotations need
to be made. Options for kitting and packaging need to be
considered.

EXTERNAL SEARCH – PATENTS
First bi-saddle seat invented around 1896. Hinged mechanism where the movement of
one saddle forced the other saddle into the opposite direction
The most recent patent was introduced in 2002.
Since then there hasn’t been any major improvements to bi-saddle bicycle seats.
EXTERNAL SEARCH – EXISTING PRODUCTS
Currently there are numerous bi saddle seats in the market, but none have been successful.

ENGINEERING SPECIFICATIONS
Find proper type of material to use for seat padding
Conduct a cost analysis on how much it would cost to manufacture a certain number of seats (10, 100, 1000, etc.)
The base of the seat will be worked on to lower the number of parts from three to one by incorporating the assembly of the base into the manufacturing process.
Develop a kitting and packaging for the parts to be placed into a compact and easy to remove/assemble package.
SYSTEM LEVEL DESIGN
The system has not been design in the CAD model yet.
This is one of the deliverables that will come at the end of the project.
