Invisible doors are useless, and bead curtains are useless. Don't believe it. The bead curtain itself is not completely isolated, so it can't stop the suffocation. According to the diagram, it is best to set up a screen at the gate, and the entrance is as high as the gate, so as to block the suffocation. In fact, the best way is to change the position of the door, but according to the picture, it is impossible. If the other two rooms in your house are unoccupied, you can change rooms. Of course, what I said is only based on the explanation of the picture. If you don't understand anything, please ask me.
Now you have given two plans and three pictures, but from my point of view, I think there is no difference between the two plans. They all changed the door to one side. Although this change is basically not right with the door of the house, it has made another kind of evil, called flying blade evil, which is very serious! Instead of this, I suggest you don't change the door, just set up a screen at your door, which is the best. According to the floor plan of your home, this is really the only way. I hope you can listen to me.
