Lets talk about framework first cause it is entirely different from Architecture and Design pattern.

Framework is like collection of tools (Functional Libraries) which we use to build something. These tools can be any thing like classes, services and any software too.

Architecture - Its like a logical view which comes in reality through Framework and perform a specific task. Its like guiding principles behind a given application.

but one thing we should always remember that there a architecture behind any framework and there a framework behind every architecture. so both are interdependent.

Design Pattern - Design Patterns are well known patterns for solving technical problems in a way that has proven itself many times. So Design pattern are like generic architecture in nature.
