Some examples of products that demonstrate good discoverability and understanding include smartphones, laptops, and other digital devices.

A good design solves problems for the user by ensuring discoverability and understanding. Discoverability refers to the ability of the user to figure out what actions are possible and how to perform them. Understanding refers to the user's comprehension of how the product is supposed to be used and what the different controls and settings mean. This is achieved through the use of affordances, signifiers, constraints, mappings, and feedback. These elements help the user to interact with the product effectively and efficiently.
