How can the SOLID principles guide the appropriate application of design patterns, and what risks arise from applying patterns without genuinely understanding the underlying problem they solve?

The SOLID principles, covering single responsibility, open closed, Liskov substitution, interface segregation, and dependency inversion, provide the underlying reasoning for why many design patterns exist and work well, and applying a pattern without understanding the specific problem it addresses often leads to unnecessary complexity, sometimes called over engineering, where a simple problem gets wrapped in layers of abstraction that provide no real benefit and instead make the code significantly harder to understand and maintain than a simpler, more direct solution would have been.

// Over engineered: a Factory and Strategy pattern for a function that never changes
// Simpler and more appropriate: a single, direct function call
