Why don't professional products have sharp corners?
At first glance, rounded corners seem like a purely aesthetic choice.
They're not.
As a Product Designer, I rarely add fillets just to make a product "look nicer." Every curve serves a purpose.
Rounded edges can:
✅ Make products more comfortable to hold ✅ Reduce stress concentrations that can lead to cracks ✅ Improve durability during everyday use ✅ Help plastic parts release more easily from injection molds ✅ Create a more refined, premium appearance
The image below shows the difference.
The enclosure on the left has sharp 90° corners. The one on the right uses smooth radii. While both designs perform the same function, the rounded version is typically easier to manufacture, more durable, and provides a better user experience.
This is what industrial design is really about.
It's not just making products look good, it's balancing engineering, manufacturing, functionality, and aesthetics to create products that people enjoy using and manufacturers can produce efficiently.
Question: What's the first thing you notice when you hold a well-designed product?
