| Mar 7, 2017 at 17:09 | comment | added | o.m. | @olegst, I didn't say incapable, I said difficult. Perhaps they make up for it with more dexterity, or whatever. | |
| Mar 7, 2017 at 7:10 | comment | added | olegst | If the aliens are incapable of pulling things, how could they develop such a material culture? | |
| Mar 6, 2017 at 17:53 | comment | added | Izkata | @o.m. Do it however the Coral Castle's swinging gate (next-to-last paragraph) was created; the gap with the walls is only a quarter-inch | |
| Mar 6, 2017 at 16:47 | comment | added | Leatherwing | A lot of restaurants have doors that are intended to only be used in one direction (to avoid knocking a tray of dishes from a server's arms). | |
| Mar 6, 2017 at 5:44 | comment | added | o.m. | You are thinking too much in modern terms. How would you build a revolving door that keeps the cold out with middle ages technology? | |
| Mar 6, 2017 at 0:17 | comment | added | NPSF3000 | @Izkata assumes that the aliens are not very long. Imagine a Worm or Rhino trying to use such a construction. | |
| Mar 5, 2017 at 23:55 | comment | added | Izkata | @NPSF3000 Revolving doors, then. Push-only, only one way, two can go through at once | |
| Mar 5, 2017 at 6:29 | comment | added | user2781 | Here's a simple way to get easy pushing hard pulling -- have the aliens prefer to open doors by pushing against them with their feet as they walk. I do this myself when my hands are full, and it's a fairly natural motion even with human physiology. | |
| Mar 5, 2017 at 0:46 | comment | added | NPSF3000 | Doubleswinging doors does not help, after all if two aliens try to go through one door at the same time (from different directions) then they will jam. To solve this jam one alien would have to go backwards - which may very well be the inconvenience they are trying to avoid. | |
| Mar 4, 2017 at 22:04 | comment | added | MissMonicaE | I don't think double-swinging doors are that hard to engineer. | |
| Mar 4, 2017 at 16:49 | comment | added | o.m. | @MedwedianPresident, those might be harder to engineer, and after a while the double doors become traditional. | |
| Mar 4, 2017 at 16:48 | comment | added | MedwedianPresident | Good idea, but in that case they would probably build doors with central hinges that can be pushed or pulled open from both sides and rotate like supermarket entrances. | |
