deployable door.

Hey guys, I was interested on deployable systems and this time I was trying to make deployable door. The door design have two approaches
1 ) zigzag pattern muira-ori origami approach 2) hand fan type single motor two sided folding approach. However, the fan type design is going to be derived with single motor for the motion half part of the panels move up while the rest parts move down. I wonder if you could help me on how to use single motor to get two parts derived. I was trying to attach the sketches but I am not sure if google group can attach media files. Thank you
