These Sketchnotings were done by one of my former students-Wei Wang. When he was studying and sketching existing products, he’s not only drawing them, but also use sketchnoting to analyze them and make sense of it. This is a very good ‘warm-up’ daily practice for all future designers, Accumulative sketchnoting practice could really help to understand better about the parting line, manufacturing constrains and design context. Those in-depth thinking or infulences you pick up everyday will gradually merge with you own design abilities.
Use sketchnoting to decode renowned designs or products in current market, break it down into components, try to understand the context and figure out the design consideration behind the scenes.
