I find revolving doors awkward to use. They can’t take that many people at a time and sometimes if there are too many people then it can jam and stop. I think the main reason revolving doors are used is to maintain the temperature of the building and prevent draughts from blowing in.
The main problem I think that needs to be solved on revolving doors is to allow passage through them easier. At the moment, I think the centre column and wings just take up too much space, and compartmentalising where people can go also makes revolving doors seem smaller than they are. A possible solution would be to move the way it separates the exterior and interior environment to the outer edge of the door.
Taking away all the elements at the centre of a revolving door and instead putting up curved glass panels around its outer edge will make a lot more space for people. These curved glass panels will then be the one parts that revolve, and if arranged correctly then should separate the exterior to the interior. The turning mechanism can also be hidden above or below the door, making it just appear like a couple of panes of curved glass that are floating.
This design still has the disadvantage that people can get caught by the turning door, but the chances of jamming the door when inside it should be reduced.
As always, if you think you have a solution or if you have a problem you would like me to try to solve then please feel free to comment it.
