Inventor of the Mundane

Coffee Collar? I hear the guy that invented these gets ten cents every time one is used.

Sometimes the plot needs a character to be very wealthy without ever actually doing anything or being particularly clever. When such a thing is needed, the character will be credited with inventing something very simple, useful, and everyday. Not anything groundbreaking like cold fusion—think more along the lines of velcro.

In other cases, the character is shown to be someone who isn't necessarily a great scientist, but clever and practical minded. Perhaps the character won't get famous or wealthy off of the invention, but their product at least will be a household name.

Compare with Weekend Inventor when inventing is a hobby rather than a lucrative living. See also Bungling Inventor, Gadgeteer Genius, and Mr. Fixit. If the inventor was an ancestor, then it is Royalties Heir. If the character only claims to have invented something, then it is Invention Pretension. In a number of cases this also doubles as a Shout-Out or a Namesake Gag.

Examples of Inventor of the Mundane include:

Anime and Manga

• From Akira Toriyama's Dragon Ball, Dr. Briefs invented capsules: nifty little things that defy the laws of conservation of mass in order that whatever vehicle, housing, or devices one could possibly need can be shrunk down to the size or a pill. Due to his rule as one of the series' Gadgeteer Geniuses, he fills that role a bit more than this (but the capsules are very mundane in that world).
