thrust, pierce, stab, prick
撞 centers on forceful, pointed contact: thrusting, piercing, stabbing, or pricking. All meanings share the idea of driving something sharp or forceful into a target.
撞 combines 扌 (hand) with 童, which likely contributes the sound and may relate to striking or hitting. The exact historical development of the compound is uncertain.
A hand 扌 beside 童, which looks like a child standing under a roof. Imagine a child thrusting a toy spear forward: the hand drives the point into something.
For ドウ, picture a hand thrusting a doughnut onto a spike: dough -> ドウ, and the doughnut is pierced.
