Design patterns are recurring sequences and best practices for repeated scenarios in software development over the years.
They are common recurring design rules
We need software design patterns to define constraints on software architecture, in order to achieve the following goals:

2- Bind to standards, eliminate ambiguity
3- Reduce maintenance cost
The idea is to maintain change, and enforce rules on a set of entities to define their behavior.
