• Professor Tim Johnson

2
Introduction

• Your manufacturing group has been selected to
  improve the companys (WIT) soldering iron.

3
Customer Demand

• The WIT HOT IRON sales team has requests from
  customers to use the Model 2001 soldering iron on
  their automated assembly line.
• The marketing department has determined that sale
  orders revenues could increase significantly.
  The increased work load could be handled with 3
  new employees.

Projected Sales Increase
5
Design Features Desired

• The soldering iron will be used in an automated
  assembly line process.
• The operator of the iron will be at a remote
  location.
• The temperature of the iron is required to be at
  300oF /- 10oF

6
Design decisions

1. How can you remotely control the temperature of
   the iron?
2. How can you sense the temperature of the iron?
3. How could HPVee assist us?

7
Needed information 1

• How does a soldering iron work?
• Sketch out or list the steps necessary to operate
  a soldering iron.

8
Needed Information 2

• How does a temperature sensor work?
• Read the literature handed out by your professor.

9
Brainstorming Session 1

• How will all the parts work together?
• Begin with a function analysis sketch.
• Have you included the feedback loop?

10
Brainstorming Session 2

• What could control turning the iron on and off?
• How could you read the sensor information?
• How could you automate the decision making?

11
Research

• Find a sensor that would be appropriate for this
  application.
• Find a relay that could be controlled by HPVee
  and handle 120 Volts AC.

12
Homework

• Write up a memo that explains how you want to
  solve this problem.

13
What to include in the Memo

• Identify the client and his needs.
• Formulate a Goal Statement.
• List the objectives.
• List the constraints.

14
Next Steps

• Use the Internet to research information on
  relays and sensors.
• Include in your memo the source of your
  information.
• The memo might well exceed one page.
• Utilize the one-page handout to guide you.

15
Good Luck

• (End of Presentation)
• Students should assemble in their work groups and
  begin sharing with each other their ideas and
  assigning tasks to accomplish their immediate
  goal of collecting information to write the memo.
