Yet another incredible technological development in dining utensils, the “clockwork wind-up fork” is a practical diet aid and not just a bizarre steampunk-themed hallucination!


Diet fads come and go, but most have at least one element in common: the requirement that individuals be deliberate about what they eat (rather than ravenously consuming everything like a starved beast).

The issue:

Unfortunately, it’s difficult to have self-control when food is delicious and plentiful.

Thus, most people eat larger portions of food than they really would if they ate a bit slower (as has been discussed previously).


To encourage people to stop eating before they are absolutely 100% full, the following technical solution is devised: “clockwork utensils” that change shape over time (thanks to a spring inside).

This spring must be wound up before use: then, over the course of a few minutes, it unwinds and turns the normal utensil into a bizarrely barely-useable piece of abstract art (see Figure 1 and Figure 2).



Fig. 1: A) a normal fork. B) The “wind-up fork”—when fully wound-up (using a wind-up key like you might see on a toy car or an old clock)—behaves like any ordinary fork. However, as the internal spring unwinds over time, the fork “fans out” and becomes more difficult to use, as seen in part C. Thus, as the meal progresses, the user must become more deliberate about using the fork.


Fig. 2: A) A normal spoon. B) The “wind-up spoon” consists of a number of overlapping metal slats (numbered 1 through 7 here). When they are all deployed, as in part B, they approximate a normal fork. C) After the internal spring has partially unwound, some of the slats will have been pulled toward the handle. By the time the spring has fully unwound, the spoon will be virtually useless!


Instead of buying a new set of silverware, you should put that money towards funding a manufacturing project to create the utensils describe above!

PROS: Could reduce over-eating!

CONS: May promote binge eating. It may also be difficult to wash the tiny mechanical parts of such a utensil.
