What is Engineering Design?

To create, fashion, execute, or construct according to plan

It defines a natural process as “a natural phenomenon marked by gradual changes that lead toward a particular result: a series of actions or operations conducing to and end…

What is Engineering Design?

ABET It is the process of devising a system,

component, or process to meet desired needs. It is a decision-making process… in which the basic sciences and mathematics and engineering sciences are applied to convert resources optimally to meet a stated objective

What is Engineering Design?

ABET (cont) Among the fundamental elements of the

design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation…it is essential to include a variety of realistic constraints, such as economic factors, safety, reliability, aesthetics, ethics, and social impact

10-Stage Design Identify the problem/product innovation Define the working criteria/goals Research and gather data Brainstorm/generate creative ideas Analyze potential solutions Develop and test models Make the decision Communicate and specify Implement and commercialize Perform post-implementation review

Stage 1: Identify the Problem

Establish the actual problem clearly, and to identify sources of information to help understand the scope and nature of the problem

Statement of the problem

Stage 2: Define the Working Criteria and Goals

How much will it cost? Will it be difficult to produce? What will be the size, weight, strength? What will it look like? Will it be easy to use? Are there any legal concerns?

Define the Working Criteria and Goals

Will it be reliable and durable? Can it be recycled? Is this what the costumer truly wanted? Will our customers want to purchase it?

Stage 3: Research and Gather Data

What information has been published about the problem?

Is there a solution to the problem that may already be available?

What is the ratio of time spent compared to overall costs?

Stage 3: Research and Gather Data

Libraries Professional associations Trade journals and publications Newspapers and magazines Market assessment surveys Government publications Patent searches The competition’s product

Stage 4: Brainstorm/Generate Creative Ideas

Try to include engineers, scientists, technicians, shop workers, production staff, finance personnel, managers, computers specialists, and a few clients

Stage 5: Analyze Potential Solutions

Common sense Economic analysis Analysis using basic engineering principles Estimation Analysis of compatibility Computer analysis techniques

Stage 6: Develop and Test Models

Mathematical models Computer models Scale models Diagrams or graphs

Stage 6: Develop and Test Models

Durability Ease of assembly Reliability Strength Environmental Quality consistency Safety Consistency of testing

Stage 7: Make the Decision

Establish a means to compare and evaluate results from the testing stage to determine which, if any, of the possible solution will be implemented

Stage 8: Communicate and Specify

Before a part, product or structure can be manufactured, there must be complete and thorough communication, reporting, and specification for all aspects of the item

Stage 9: Implement and Commercialize

Management and key supervisory personnel

Technical representatives– Human resources, financial, purchasing,

marketing, and sales personnel

Attorney and legal support staff

Stage 10: Perform Post-Implementation Review and

Assessment Review data on production efficiency,

quality control reports, sales, revenues, costs, expenditures, and profits

Detail product’s strengths and weaknesses Suggest improvements
