SOLID is a set of design principles, not a design pattern. The five SOLID principles guide the structure and behavior of object-oriented design to make software more flexible, maintainable, and scalable. They don't provide concrete solutions like patterns do, but instead, they help you write better code by ensuring your classes and systems are well-structured and easier to modify or extend.

Design patterns are specific solutions for recurring problems in software design (e.g., Repository, Singleton, Strategy).
Design principles like SOLID provide general guidelines on how to write good object-oriented code that is maintainable and scalable.
SOLID is not a design pattern but rather a collection of design principles that help you create better software architecture.
