⚙️ 设 (set up) + 备 (prepare) = equipment that's set up and ready
设 means to establish or set up; 备 means to prepare or have ready. Together 设备 names the equipment or devices that have been set up and prepared for use — installations, gear, apparatus.
设 — speech 讠 + hand holding tool 殳
设 combines 讠 (speech) with 殳 (a hand wielding a tool or weapon), suggesting giving orders to set something up. The original sense was to arrange or establish through command, which extended to today's meanings of 'set up,' 'design,' or 'suppose.'
