When one looks at a container (a normal sized one, not one of the bigger ones in the deWulf setting), one of the most complex parts of a container is the doors. No surprise, as they have to be water tight (reasonably), have effective latching mechanisms, and can be locked with any number of tools. A spaceborne container has to do all of these things, but be capable of dealing with forcible changes in pressure, as well as be built to a more robust standard (since maintaining a constant pressure is a concern, it has to be able to take some damage and not spring a leak).
This doodle is looking a bit at the way that the doors of a Space Container™ might differ from a normal container. Normal containers have locking cams at the top and bottoms, with a large lever handle to lock and unlock them. instead, this is done with powered pins on the above container (like a vault door). While a normal container has just some loops in the levers for a seal (pin or strap), this container uses a small integrated security computer.
While this is a cool idea, a part of me also acknowledges that this really is an overengineered solution to a comparatively simple problem, and I’m not really sure that this is a canon solution to smaller shipping containers that are in fact space-rated. One challenge that this design really doesn’t handle well (or at all, really) is that the container’s contents would be pressurized, while in space the outside would be a vacuum. This would mean that there’s a pressure differential that wants to make the doors swing outwards, which is the same way that they’re designed to open. So the locking system would have to be fighting against that. And the actual seals would have to be working against it as well. It would be much simpler if the space-rated containers had doors that opened inwards (then the pressure works to keep the doors securely closed). But that cuts into internal volume. More thinking on this is required (perhaps an integral roller door?)
