Great engineers brainstorm LOTS of ideas, sketch them, and build cheap PROTOTYPES to learn fast before the real build.
💡From Idea to Object: Brainstorm → Sketch → Prototype
You don't build the real thing first! A quick, cheap prototype lets you find problems early — when fixes are easy and free.
💭 1. BRAINSTORM
Dream up tons of ideas — even silly ones. No judging yet! More ideas = better choices.
✏️ 2. SKETCH
Pick promising ideas and draw them with labels. Sketching is fast and shows how parts fit.
📦 3. PROTOTYPE
Build a rough model from cardboard, tape, or clay to test if the idea actually works.
🔁Iteration: Each Round Makes It Better
🔁 Repeat the loop — version 2 beats version 1
Build a prototype of your idea.
Test it — see what works and what breaks.
Improve the design using what you learned.
Each loop is one iteration — and it keeps getting better!
🌎In Real Life: Junk-Box Prototypes Save the Day
Engineers test ideas with cheap, throwaway materials first. If the cardboard version fails, you've only lost tape — not time, money, or a finished product.
🔑Key Terms
💭BrainstormQuickly come up with many possible ideas without judging them — quantity first, picking later.
🌈Divergent ThinkingBranching out to lots of different, creative solutions instead of just one "right" answer.
✏️SketchA fast, rough drawing of an idea, with labels, to show how it might look and work.
📦PrototypeAn early, cheap, test version of a design built to try out and learn from before the real build.
🧩ModelA simplified stand-in for the real thing that shows its key parts and how they connect.
🔁IterationOne round of build, test, and improve — repeated again and again to make a design better.
⭐Remember: don't fall in love with your first idea! Brainstorm many, sketch the best, and build cheap prototypes — then test, improve, and repeat until it's great.
