THE EDP THE ENGINEERING DESIGN PROCESS STEP 1

THE EDP (THE ENGINEERING DESIGN PROCESS)

STEP 1 �Identify the Problem � Setting a Goal �Criteria ---- the rules you must play by �Constraints------ what you cannot do or your limits ( What does this mean? – Need to know what the problem is so you know what to do. --- Fixing it --Possible outcomes / prediction-----) ( Can you make a problem bigger so that maybe you will perform better? ---- Yes, taking risks …. learn from mistakes )

STEP 2 �Identify the Criteria and Constraints Criteria ---- the rules you must play by Constraints------ what you cannot do or your limits

Design Constraints

Constraint Types �Limitations to the design �Required parameters that have to be met

Technical Constraints �Size and shape of the object �Materials that should be used

Legal Constraints �Make sure your design meets laws and regulations �Ensure the design does not violate existing patents

Time Constraints �Limits to the amount of time that the design process can take

Financial Constraints �The costs of the design (also called Design Budget) �Designer must take into account the cost and amount of profit they want to make once the invention is manufactured

Production Constraints �Restrictions on how the device can be built �The designer must look at the tools and materials available to decide these constraints

Design Briefs �A document that contains: The Problem Statement List of the designer’s criteria List of the designer’s constraints �The document must be reviewed to see if information needs to be added. �I give you one ahead of time, but you must create your own and add your own problem statement, criteria, and constraints.

Reviewing Design Briefs �You should ask yourself these questions when reviewing your design brief: Does anything need to be added to the problem statement? Is this statement clear? Does it state the problem? Is the problem open-ended? Are the criteria clear? Was anything left out? Are there more requirements or constraints?

Example Design Brief

STEP 3 �Brainstorm possible solutions (must write or record) �Brainstorming Rules - Hitchhiking is allowed ( taking ideas and stealing - them…. . BUT you have to modify) (Innovation) No Put-ups or Put-down ( Why? Discouragement , ppl can become over confident) No judgment is passed Everyone has a turn to talk and everyone is allowed to pass Freewheeling (saying funny stuff is good!)

STEP 4 �GENERATE IDEAS - Look at the brainstorm and see if you can combine ideas

STEP 5 �Explore the good ideas from the brainstorm. �Get at least THREE Ideas ( You can take the brainstorming and modify. Kill the bad ideas. Combine ideas )

�SKETCHING THUMBNAILS What are Thumbnail sketches

STEP 6 �Select an Approach ( Based on research and “digging”into the possible solutions )

�TECHNICAL DRAWING What is a technical drawing?

STEP 7 �Build a Model or Prototype ( Model is not full scale and it does not have to work, but it must show all the pieces/parts) ( Prototype is full size working model that works. )

STEP 8 �Test and Evaluate �How many trials do you have ? �What does evaluate mean?

STEP 9 �Refine the Design (make sure all the pieces and parts are going to work) �Can you make anything better?
