Hi, the system is now in its development phase, therefore we havent gone through further details yet. We plan to build the rings and sticks using standard parts found in normal construction stores and we would preferably use polymer parts, to keep low weight and cost. We are working on a detailed part list, but we also want to observe the development of the IDEO project and collect more feedbacks.
Hello, thank you for the feedback! The idea is to have the umbrella fixed on the upper ring (tip of the pipe) and a sliding ring that would open or close the umbrella, when sliding up and down (using a stick depending on the height of the central tube, which would be defined according to the house height). So yes, the umbrella is fixed in one point, but we could think in a lock/unlock system to remove it.
