Don’t let “BIG COFFEE” trick you into buying their overpriced coffeepots and carafes—use this one weird toothpaste tube trick to save time and promote a harmonious work environment and never unexpectedly run out of coffee again!

 

Background:

If you have a communal coffee carafe at work, you will undoubtedly have encountered the situation where someone poured the last cup of coffee and didn’t make a new pot.

With a standard coffeepot or carafe, there’s no possibility of getting “just one more cup” out of an empty container—it’s just empty.

But! There’s one thing that always seems like you can get one last use out of it, no matter what: a toothpaste tube.

Proposal:

The main issue: since it’s so easy to pour coffee out of the coffeepot, it’s easy to pour the last coffee and then walk away (Fig. 1).

regular

Fig. 1: A coffee carafe, like one you’d see in an office or at a hotel breakfast, can be operated by pressing the lever at (a), dispensing coffee out of the spout at (b).

To fix this, we simply need to make it more difficult to extract the last few cups of coffee. It if became progressively more difficult to get coffee from the communal container, then people could recognize that they were taking the very of it, and would (hopefully) be more likely to start a new pot of coffee.

The proposed container (Figure 2) is essentially a huge toothpaste tube in a support frame.

Fig. 2: Instead of a traditional carafe or coffeepot, coffee can be placed into a squeezable toothpaste-tube-like bag that fits into a support frame. To dispense coffee, simply squeeze the bag!

Figure 3 shows the progression of the tube from a full state (left) to a nearly-empty state (right).

A full coffee container (leftmost column) would look similar to a 2-liter soda bottle. As coffee is squeezed out of the tube, the dispenser would gradually come to resemble the rightmost column.

Conclusion:

Don’t buy another regular coffee container for your workplace—this new dispenser is the way of the future.

PROS: Prevents you from being shocked and dismayed at your coworkers’ refusal to make more coffee.

CONS: The “squeeze to dispense” method will probably spray nearly-boiling coffee across the room on a regular basis.

Bonus Figure A: In the initial concept for this idea, the carafe lever would become more difficult to operate as the liquid level lowered, but the “toothpaste tube” idea was only metaphorical.

This “smart carafe” will streamline office coffee acquisition and, if it is smart enough to use Microsoft Excel, possibly replace YOU as well! Smash it before it is too late.

Background:

In many office environments, communal coffee is brewed periodically. But it is difficult to tell how old the contents of the carafe are (or if it’s even coffee from the day before).

Fig 1: The classic coffee carafe. No bells or whistles. How barbaric!

Proposal:

The carafe should be able to easily tell you the following information:

  • How long since it was filled
  • How full it is
  • What temperature its contents are

The simplest proof-of-concept “smart carafe” would just have a small switch on the lid that would start a stopwatch on the side of the carafe. This would tell you when the lid was last opened, which would normally be a reasonably estimate for when the coffee was last made.

More complicated systems could use a floating sensor to determine the percentage filled (which would work even for liquids of other densities, in case you need a carafe full of liquid mercury for some reason) and a temperature sensor. Of course, a frosted glass window on the side of the carafe would also be sufficient for determining percent-fullness without any electronic gizmos.

Conclusion:

Your office should switch to the smart carafe for all future breakroom-liquid-containing needs.

PROS: The smart carafe upgrades the coffee-drinking experience from “satisfactory” to “transcendent.”

CONS: The carafe might be too smart. Did you ever see the Kubrick film 2001? Like that.
