About this category

Household products sell on small, visible improvements: a mop whose wringer folds away, a window cleaner whose magnet strength is set with a dial, a kettle lid that stays on when you pour, a grater whose coarse and fine panels fold shut like a book, a powered scrub brush that rinses its own bristles inside the body. These are the kinds of features that can be shown in one product photo or a five-second video.

Every patent in this collection was filed only in China, so it does not restrict making and selling the design in the US. On each product page we explain the mechanism in plain language, list realistic use cases - and where the product is less suitable - and set out the points to plan for in the US, such as food-contact materials, magnet warnings and cycle testing.

What to look for in this category: low part counts, injection-molded parts that share one or two molds, and a feature that justifies a price above the basic version.

New in the kitchen: a water bottle with a ribbed citrus press and filter bowl built into its mouth, and a dish brush whose soap chamber refills from a detergent tank every time it is parked in its stand.
