Three diagrammatic concept sketches of walkers with labeled features, showing a smart safety walker, a multi-functional convenient walker, and a lightweight travel walker.

Create three concept sketches of walkers for elderly people, focusing on different functions. The style should be clean, clear lines, and diagram-like, with labeled key features. Each walker is separate in the image. 1. Smart Safety Walker: - Wheels with anti-tip mechanism - Handle with smart brake - LED light for night visibility - Built-in health sensors (step count, heart rate) - Four-leg support or stable wheels - Sketch style, clear line art, labeled functions 2. Multi-functional Convenient Walker: - Foldable seat for resting - Detachable shopping basket or small storage rack - Integrated cane/handstick option - Adjustable handle height - Shock-absorbing wheels - Sketch style, clear lines, labeled functional areas 3. Lightweight Travel Walker: - Ultra-light foldable frame (aluminum or carbon fiber) - Modular detachable handle, wheels, and seat - LED light or reflective strip - Small storage rack for water bottle or personal items - Sketch style, clean line art, labeled functions, emphasizes portability Additional instructions: - Each walker is distinct and clearly separated - Diagram or blueprint style, not realistic rendering - Focus on structure and function, easy to read - Line drawing / sketch illustration Mehr sehen
