于 = 亅 + 二 : Mnemonic symbol: prepositions (in, at, on, to, ...) are what glue the sentence together. Honey is as sticky as glue, so I'll represent 于 by a honey jar.

Yu the Great (于) was assigned to repair the electronics of the space station's kitchen (Ø2), but instead he was snacking honey from a honey jar (于). Unfortunately his capacitor (二) got stuck in the honey and now he has to use a crowbar (亅) to lever it out.

助 = 且 + 力 : Mnemonic symbol: water wings helping you to learn how to swim.

Julian Giant Squid wants to learn how to swim and put on a lot of floaties in the space station's bathroom. As he hits the power button to inflate the high tech floaties remotely he forgot that there are still a lot of floaties left, stored in the shelf—he is reminded instanlty as also all of them inflate.

人 = 丿 + ㇏ : Mnemonic symbol: Neanderthal Man (人). Robinson Crusoe (r-) is looking for snacks in the encampment's kitchen (-en2) when he suddenly spots Neanderthal Man (人). Neanderthal Man offers him a banana (丿), but Robinson Crusoe doesn't trust the present and pokes it with a finger (㇏).
