Design Process

The 2nd step in the engineering design process is

• Construct and Test

• Define the Problem

• Evaluate

• Generate Concepts

All of the following are steps in the engineering design process EXCEPT:

• Construct and Test

• Evaluate solution

• Client check

• Present the solution

You are part of a design team tasked with developing a new bicycle helmet. After initial testing, the helmet’s outer shell cracked under impact stress. The team has decided to revisit the design and use different materials

What phase of the engineering design process is the team currently in?

• Define the problem

• Generate concepts

• Develop a solution

• Iterate and improve the design

Your team is analyzing test data on various materials for the helmet's outer shell. The data includes impact resistance values for four materials: plastic, fiberglass, carbon fiber, and metal. The range of the data for carbon fiber seems much wider than for other materials.

Which data visualization tool would best help you visualize the spread of data for the materials?

• Decision matrix

• Box plot

• Line graph

• Histogram

The client for the helmet project has given your team the following instructions: The helmet should be lightweight, affordable, and meet safety regulations. The client also wants the helmet to be available in multiple colors.

Which document will you use to ensure that the team stays focused on these requirements and constraints during the design process?

• Decision matrix

• Design brief

• Box plot

• CAD model

The __________ phase of the design process involves building and testing physical or virtual models to identify potential problems.

The first step in the engineering design process is to __________ the problem, where engineers clearly define the issue they are trying to solve.

A design brief typically includes the problem statement, constraints, and __________, which outline what the solution must achieve to be considered successful.

In a box plot, the line inside the box represents the __________, which is the middle value of the data set.

• Lower quartile (Q1)

• Upper Quartile (Q3)

• Median

• Max

How does feedback from prototype testing influence iteration?

• Feedback is ignored if the design meets initial requirements

• Feedback eliminates the need for future testing

• Feedback leads to improvements and refinements in the design

• Feedback allows engineers to skip steps in the design process
