As a web and product designer, I’m always paying attention to how things are made. Not just websites and apps, but everyday objects too. Some of the best design is invisible, they work so well that we don’t even notice them. Here are a few simple design details I love that people use every day without realizing how smart they are.

The toothpaste cap that stands the tube up

Many toothpaste tubes have flat caps so you can stand them upright. This saves space and makes sure the toothpaste is always ready to come out. It seems obvious now, but someone had to think of it.

Microwave “add 30 seconds” button

One of the most-used buttons on any microwave is “Add 30 Seconds.” You don’t need to think or set a timer. Just press once and go. It’s a perfect example of reducing friction in everyday tasks.

Shopping cart child seats

Ever notice how smoothly the child seat folds up when you put groceries in a cart? It moves out of the way without you needing to think about it. It’s small, but it makes shopping easier.

Door handles that show you how to use them

Some handles are for pulling. Some are for pushing. The best ones look like what they’re meant for. A flat plate makes you want to push. A loop makes you want to pull. You don’t need a sign when the design does the talking.

USB-C

We’ve all struggled with classic USB-A plugs going in the wrong way. The move to USB-C was a design upgrade: no wrong way to plug it in. It’s small, but it’s made millions of lives less annoying. And, now, you can charge your phone, laptop, headphones, and even your coffee mug warmer with just one cable.

These little things may seem small, but they show care. They’re reminders that design isn’t just about how something looks. It’s about how it works and how it makes people feel.

This is just Part One of a series I’m working on: a look at the timeless, invisible design choices that shape our daily lives. If you enjoyed this, subscribe to my email list to get updates when the next one drops.
