Sink traps (the U-shaped bend under the sink that serves the
dual purpose of preventing sewer smells from coming up the
drain and keeping accidentally dropped items from
disappearing for good) are immensely useful things, but they
can be a huge pain to take apart when necessary for cleaning
or
recovery purposes. It often requires large pliers or a pipe
wrench, and sometimes considerable brute force depending on
how shoddy a job was done of installing it in the first place. This task would be made considerably simpler by attaching
the trap by means of toggle latches rather than the
traditional plumbing nuts. Simply line up the washers on both
sides of the trap, and fasten the latches to create a seal and
hold the trap in place.

That's fair enough. However, all the modern traps which I've
seen use plastic screw-collars (and/or simple push-fits), and
are almost as easy to dismantle as what you describe... |
|

As you say, the difficulty depends on how it was installed. Standard fittings should seal well if given a few turns of thread tape and tightened not much more than hand tight, and they will then be easy to dismantle when needed. |
|
| |
Any increase in complexity, such as implied by toggle latches, is likely to cause more problems than it solves, and may be even more likely to be stuffed up by a ham-fisted plumber. |

//To use a plumbing analogy: it’s not under pressure// |

So, this is a plumbing analogy to describe a plumbing
situation. Ingenious! It's the linguistic equivalent of a 1:1
map. |

At my old middle-school, in the art department, they had great big deep sinks to clean paints, and plaster-of-paris and all sorts of other arty-stuff prior to putting it away. Rather than let all that goop go down and block the drains, the sinks all drained into a kind of secondary super-sink underneath, that managed to collect all the heavy stuff at the bottom, and allowed the water to drain off via a sort of vertically-placed overflow drain half-way up the secondary sink. All the bits of stuff collected in the bottom in murkey mountains of greyish ooze. Any rings, earings, toys, brushes or other stuff that somehow managed to drop drown the sink could easily (if somewhat ickily) retrieved from the undersinks. |

So, this is probably not ideal if you use your sink for food preparation or washing up. Fair enough to collect old bits of paint and plaster, probably not so good if it's all oily foodstuffs. |

I think I recall a U-bend with a built-in port (to use a non-plumbing analogy) at the bottom. |
