This is a simple idea for hotels that cater to families. It's not uncommon for kids to think it's funny to press all of the buttons on their way out of the elevator so it will go to every floor. The result is that everyone waiting for it has to wait a little bit longer. A weight-sensitive mat covering
the elevator floor could fix that. If the mat sensed that there was less than 20 pounds on it when the doors closed it would signal the console to de-select every button.
(Elevators that already had weight sensor built into them for safety reasons could be upgraded to do the same thing.)
Something about this idea feels familiar. If you've seen it someplace else let me know so I can delete it.

I had a similar idea to have toggle buttons in lifts (see link), I wrote to the two major lift companies and both said, basically, they'd think about it.
With your idea am I right in saying that people under 20 pounds wouldn't be able to use the lift ? what if people were in the lift with one of the little tykes (surely it's not a problem unless others are inconvenienced). |

Some of the lifts here will ignore multiple button presses
under certain circumstances to prevent pranking, but we
haven't been able to figure out the exact system. |
|
| |
just a reset button should work. but
then again this might be fun for
pranking too. |

In the elevators at Ogg Hall in Madison, WI, unless they've changed in the last 25 years or so (which they may have), it is possible to cancel a floor button when the elevator is stopped at a floor by pressing it at the same time as the button for the floor where the elevator is stopped. |
|
| |
For example, if the elevator is stopped at floor 3 and the floor 11 button is set, pressing and holding the "3" button while pressing and releasing the "11" button will clear the floor-11 request. |
|
| |
I don't know whether this was a deliberate design feature, or simply an 'accident' of the floor-clearing logic (pressing multiple buttons simultaneously could connect their latching circuits; the "clear" signal for the current floor might thus override a default "set" signal. |
|
| |
In any case, I've never noticed such a feature on any other elevator though to be sure it has been ages since I've tested for it. |

neilp - People with little ones weighing under 20 pounds would still be able to use the lift. The mat would calculate the combined weight of everyone in the elevator before deciding if it was empty. This does mean that unescorted toddlers would probably not be able to use them. That might turn out to be an unexpected benefit though. Suppose a single parent is waiting for an elevator with his/her kids in tow. One kid runs back down the hall. The parent goes to get him. The elevator door opens. The toddler steps in. The elevator door closes because someone on another floor has pressed the call button. Away goes the toddler. (If this has happened at all it must be pretty rare though since we never hear about it.) |

bris - The only thing I can see in common between the two ideas is the concept of a weight sensor. In the 2002 idea it's suggested that the sensors be used to keep from stopping to pick up more passengers when the weight is nearing its limit (if I understood it right). This idea is intended to keep the elevator from stopping to pick up no passengers when the load is next to nothing. I guess in both cases the ideas would keep the elevator from making needless stops but the logic for doing so is completely different. |

Hence the reason I noted the link as "related." |

This would definitely make elevators harder to prank, although kids could still prank it by leaving something heavy in it. The obvious solution is to reinstitute elevator attendants. |

how about an alarmed cover, simular to those found on fire alarms |
