A black-and-white hand-drawn style idea sketch of a foldable laundry drying rack designed for active seniors. The sketch should illustrate problem-solving features: 1. Automatic height adjustment system to make it easier to hang laundry without lifting arms too high. 2. Stronger rods and frame support for heavy wet laundry like blankets or towels. 3. Stable legs with rubber pads to prevent slipping or tipping over. 4. A simple button mechanism for easy folding and unfolding without finger injury. 5. Small wheels for smooth movement and a locking system for stability. Style: inventor’s notebook style, minimal technical sketch with arrows and short Korean annotations explaining each function. Layout: multiple perspective views showing each solution clearly.
