establishment, provision, prepare
設 centers on setting something up for a purpose: establishing an organization, providing equipment, or preparing arrangements in advance.
設 combines 言 (words, speech) with 殳, which likely contributes the sound and the idea of setting up or arranging. The character suggests establishing something through verbal or formal means.
Words (言) and a tool-like action (殳) come together: imagine using speech and tools to set up a new facility, providing everything needed.
For セツ, picture a set of blueprints being prepared: set -> セツ, and the words on the plans establish the new building.
