Define Engineering Design
Define and Explain the Engineering Design Process
Assignment: Gantt Chart for Final Project (Project Timeline)– See example in Final Design Report Example in Website
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
