What is Engineering?
Problem solving Design Innovation and Creativity Application of math and science Teamwork and Leadership Communication Professional
What do Engineers do?
Work in industry, government or consulting Develop surgical instruments Design municipal infrastructure (water
distribution lines, water treatment) Remediate a contaminated site Design a robotic systems for a production
line in a factory
Engineer or Scientist – What’s the difference?
Science – understand concepts, learn about theory and principles, have expertise
Engineering – applies principles of math and science to solve real-life problems
Engineers and scientists often work together as part of a team
Engineering is a profession – P.Eng

Design Engineering
Design courses starting in first year First year - marble launcher Second year - windmill powered
battery charger Third year - design of soccer playing
robots Fourth year design courses
The Mission:
Design, build and test a device to transport a marble from less than a foot off the floor into a column of water
Slow the descent of the marble to the greatest extent possible
Maximum time under water, not touching the bottom
The Rules:
You may attach a device to the marble You may not change the marble Human energy can only supply potential
energy to the launch mechanism If you add something to the water, it
must be added with the marble No explosives can be used
More Rules:
Made entirely by recycled materials
Constructed by the group Total equivalent cost less than $50 Safe for a nine year old to use No animals may be used/harmed
in the design
The column
Column 4 feet high Water to within 2” of the top A shallow sheet metal funnel will be
attached to provide a greater entry radius
Launch mechanism can touch the metal funnel but not the column or the water
The Criteria
How long does the marble take to descend to the bottom of the water column
Cost (cheaper is better) Aesthetic appeal Simplicity of design Unique, innovative design

Solution 1 – Elastic launcher
Launching arm on an elastic band, potential energy by drawing back the arm launches the marble
Adjustable to change the range of the launcher and improve accuracy
Solution 1 – Cork floater
Marble attached to cork – buoyant forces counteract the weight of the marble
Flat piece of cork acts to provide drag in the water
Solution 2 – Weight pulley on a ramp
Weight (pop bottle filled with nails) attached by string to ½ popcan holding the marble flotation device over a pulley (old inline skate wheels)
As weight falls, the can with the marble leaves the floor, rises to the column and tips the marble device into the column
Solution 2 – Oil capsule
Spherical capsule filled with canola oil (lighter than water)
Fishing weights and paperclips to balance weight
Solution 3 Counter-weight lift device
Elevator type lift – wooden structure with a angled platform
Free weights attached by string to the platform
Once released from the top of the structure, the weights fall, and the platform rises, releasing the flotation device into the column
Solution 3 – Water balloon
Marble in a large water balloon, diameter slightly less than the diameter of the column
Attached to a PVC pipe capsule containing alka-seltzer
When balloon is released, water leaks into capsule through a drilled hole
Reaction with alka-seltzer releases gas, increasing the balloon diameter
Biological Engineering
Applying engineering to biological systems
Food engineering Biological processing Biomechanics or biomedical
applications Ergonomic design applications Students can mix and match
4th Year Design Projects
Project SOY – has included projects involving food coatings, alternate food packaging, SOY substitutes
Analysis and bioremediation of contaminated soils
Pedobarograph Device for measuring forces during
teeth grinding/Bruxism Surgical Instrument for back surgery
Engineering Systems & Computing
Computer engineering (hardware) and Software engineering and Systems engineering
Embedded systems• Elevators• Microwaves• VCR• Car
Interaction – hardware, software, environment
4th Year Design Projects
Portable MP3 music machine Robotic arm application where arms
work in collaboration to complete a task Intelligent mechatronic aide for
recovering stroke patients Voice recognition and translation Home robot controlled via the internet
Research – Computer Vision Technologies
Robot that has vision and interacts with and tracks people
More sensitive than automated visual tracking
Applications – monitoring manufacturing, robotic arm routines and prevention of line shutdowns
GM – vehicle technology to prevent drivers from falling asleep, driver assistant for traffic surveillance
What is in our water?
Our water originates from lakes, reservoirs, groundwater and must be treated before use
Water recycling - Guelph’s wastewater is Brantford’s drinking water
Escherichia coli (O157:H7), Giardia lamblia, Cryptosporidium parvum
