Answer from AI

Yes, some design patterns can conflict with SOLID principles, especially if their application leads to violations of these principles.

For example:

  • God Object — a pattern where one class contains too many responsibilities, violating the Single Responsibility Principle.
  • Singleton — often criticized for violating the Dependency Inversion Principle and making testing difficult.
  • Active Record — combines business logic and data access, which can violate separation of concerns.

Therefore, even well-known design patterns can conflict with SOLID if used without considering the context and good design principles. It is important to apply patterns consciously to avoid degrading the architecture.
