make, prepare, arrange
拵 centers on the act of making or preparing something with one's hands, often implying careful arrangement or construction.
拵 combines 扌 (hand) with 存, which likely contributes a phonetic element. The exact historical development is uncertain, but the hand radical suggests manual action.
The hand radical 扌 beside 存 suggests using your hands to make or prepare something, like arranging tools on a workbench.
For ソン, imagine a son helping his parent make something with their hands: son -> ソン, and the son carefully prepares the materials.
