Systems Design

Table of Contents

This page details the system-level concepts we selected as well as the process and reasoning we used to make our decisions.

Functional Decomposition

The Functional Decomposition is a tool we used to break the system down into several subsystems and subsequently break these subsystems down into specific functions. By doing this, we were able to create a comprehensive list of functions for which we could brainstorm potential solutions.

In order to take full advantage of solutions that already exist, we researched methods for controlling the flow of granular particles. Click the link below for a summary of our findings.

Phase II Benchmarking

Concept Development

This includes three phases:

Below is the Morphological Chart we created to help us determine which concepts were more viable.

Systems Architecture

The Systems Architecture is a tool we used to visually demonstrate how our proposed design will look and how our subsystems will interact with one another. Click the links below to see the block diagrams and renderings we have developed.

In order to determine if several of our concepts were feasible, we performed several engineering analyses. Click the link below to see our process and results.

Feasibility Questions, Information, and Analyses

Test Plans

In order to ensure that we have met all of our engineering requirements at the end of MSD, we needed to devise a plan for testing our device and comparing the results to the metrics we have set. Click the link below to see a summary of our test plan.

Test Plans

Risk Assessment

In an attempt to anticipate and properly react to potential issues that we will encounter throughout the course of MSD, we have prepared and will continue to add to the following Risk Assessment:
