Your coffee cup contains 5 engineering decisions you never think about:
1. Wall thickness - thinner = lighter, thicker = better heat retention. They ran the math.
2. Handle angle - tested ergonomically for the average hand span across 3 continents.
3. Rim curvature - affects pour rate. Flat rims spill more.
4. Base diameter - optimized to not tip at the 23° angle of a shaking table.
5. Glaze composition - food-safe, non-reactive, survives 500+ dishwasher cycles.
