Engineering Design Process

A series of steps that guides engineering teams as we solve problems.

Engineering Design process is ___

Iterative - repeat the steps as many times as need, make improvements along the way as we learn from failure and uncover new design possibilities to arrive at great solutions.

Engineering Design steps

(1) Ask: Identify the Need and Constraints

Engineering Design step 2

(2) Research the Problem

Engineering Design step 3

(3) Imagine: Develop Possible Solution

Engineering Design step 4

(4) Plan: Select a Promising Solution

Engineering Design step 5

(5) Create: Build a Prototype

Engineering Design step 6

(6) Test and Evaluate Prototype

Engineering Design step 7

(7) Improve: Redesign as Needed

Ask: Identify the Need and Constraints

Step 1: Define or describe the problem, identify who has the problem or need and specify the potential objective or as to why it is important to solve. The constraints of the problem is essential to be identified too which includes the limitations, the requirements and goal.

Research the Problem

Step 2: Find about the details of the problem and do research; collect information through interview; investigate existing technologies

Imagine: Develop Possible Solutions

Step 3: Be creative, discuss ideas with others to make as many possible solutions; teamwork is important

Plan: Select a promising solution

Step 4: Choosing a solution, revisiting the needs and constraints (financial, environmental, cultural); selecting 1 solution and making a plan

Create: Build a Prototype

Step 5: Materialize the idea after conceptualization; can bemade from other materials and final version may differ

Test and Evaluate

Step 6: Is the prototype working according to the requirements? You should present the results and get feedback

Improve: Redesign as Needed

Step 7: Share the results, improve the prototype and iterate the design until final results have been achieved

Forms of engineering in writing communication

Homework presentations, progress reports, technical reports, lab reports

Problem solving step 1

(1) Defining the problem

Problem solving step 2

(2) Simplifying the problem

Problem solving step 3

(3) Performing the solution or analysis

Problem solving step 4

(4) Verifying results

Defining the problem, Understanding the problem

Problem solving tep 1: What is being asked, known, and determined?

Simplifying the Problem

Problem solving step 2: Make appropriate assumptions and understand the fundamental concepts and physical laws; when and where to apply these laws and limitations?

Performing the solution/analysis

Problem solving step 3: Selecting appropriate model(s) by applying either mathematical concepts, physical laws, engineering fundamentals, showing appropriate units, and showing results in numerical or parametric forms

Verifying the results

Problem solving step 4: Does the answer make sense Is it correct? Should you ask your professor? Should you check references/textbooks to match answers? What are the range of answers and other ways to analyze the problem? How do you simplify or approximate the problem for ball park answer?

Homework presentation step by step

(1) Given (problem statement and extracted); (2) Find: What is to be determined?; (3) Solution (Appropriate model(s)/diagram(s) with step by step calculations

Homework presentation layout

NUmber of sheet and sheets in the assignment at top right, given, find, solutions with diagrams on left, calculation of right with all assumptions; answers: Disable underline (always double line), do not forget about units

Progress Report

Short communication to organization members or project sponsors. Summarizes completed work, upcoming tasks, and addresses problems with recommended solutions.

Executive Summary

Brief communication to top management. Conveys study or proposal findings. Few pages long, with references to more comprehensive reports.

Memo Format

Short memos convey brief information to interested individuals

Technical Report contents

Title, abstract, objectives, theory and analysis, apparatus & experimental procedures, data & results, discussion of results, conclusions and recommendations, references, appendix

Design report contents

Title, executive summary, design objectives, design assumptions, limitations and specifications, design summary, design drawings, alternative designs, economic analysis, conclusions and recommendations, references, appendix

Technical report - Abstract

Most crucial report section. Includes concise statements on Objectives, Procedures, Results, Conclusions, and Recommendations. Typically written last.

Technical Report – Objectives:

Explicitly states the investigation's purpose; Lists objectives (e.g., 1., 2., 3.).

Technical Report – Theory and Analysis:

States principles, laws, and equations (numbered); Presents analytical models, defines terms, and lists assumptions.

Technical Report – Apparatus and Experimental Procedures:

Presents apparatus and instrumentation details; Describes experiment procedures with itemized steps; Includes schematic diagram of experimental setup.

Technical Report – Data and Results:

Presents results in tables or graphs; Includes titles, headings, units, labels, and numbered figures and tables; All figures and tables must be numbered and have descriptive titles; All figure numbers and titles should be placed below the figures. All table numbers and titles should be placed above the tables.

Technical Report – Discussion of the Results

Emphasizes and explains important experiment results. Compares experimental and theoretical results.

Technical Report – Conclusions and Recommendations

Compares objectives with experimental results. Supports conclusions with appropriate references. States recommendations based on conclusions.
