Bioengineering and Engineering Design Process S2 Flashcards
What is engineering?
Engineering is a branch of science and technology concerned with design, building, and use of engines, machines, and structures.
What does the Engineering Design Process refer to?
Products and Processes that are designed to serve our needs
How many steps are in the Engineering Design Process?
5
What are the steps of the Engineering Design Process?
Ask, Imagine, Plan, Create, Improve
What is the correct order of those steps?
Ask, Imagine, Plan, Create, Improve
What do you do in Step 1: Ask
Find the problem and goal and research.
Ex: What have others done?
Ex: What are the constraits
What do you do in Step 2: Imagine
Brainstorm Ideas: What are some solutions? Choose the BEST one!
What do you do in Step 3: Plan?
Draw a diagram, make a list of materials needed, and make a prototype.
What is a prototype?
A test model of a product.
When creating a prototype……………..
- Make a full scale model when possible.
2. Include all features and improvements which are important to the function of your prototype.
What do you do in Step 4: Create?
You have to follow your plan and create the desired product, test it out, and analyze the cost-benefit.
What is Cost-Benefit Analysis? (Answer question in question form)
Is the cost of the designing and producing the new product worth its benefit?
What do you do in Step 5: Improve?
Modify your design and make it better, then you test it out! (Share information)
What is engineering? (Second answer)
Engineering is the process of creating technology
What is engineering? (Second answer)
Engineering is the process of creating technology
What is bioengineering?
Bioengineering is the application of engineering (technology) to living things, such as humans and plants.
What do bioengineers do?
Bioengineers look at problems that occur in living things and invent technology that will help these problems.
What is assistive bioengineering?
Technology that is developed to help organisms, but DOES NOT change them (only temporary).
What are some examples of assistive bioengineering?
ASSIST = HELP
- Eyeglasses
- Wheelchairs
- Antibiotics
- Artificial Limbs
What is adaptive bioengineering?
Technology developed to help living organisms and permanently changes them.
What are some examples of adaptive bioengineering?
ADAPT = CHANGE
- Lasik Eye Surgery
- Knee Replacement
- New Strains of Disease Resistant Crops
- Biofuel
What can adaptive bioengineering also be?
A modification of existing technology.
What is an example of a different type of adaptive bioengineering?
A watch that not only tells time but jeeps up with how far you have walked.
What is biofuel?
Biofuel is made from living matter (nature).
Example of a biofuel:
Ethanol
Medical Devices
Any material, apparatus, or sofware, or other article that is used to:
- Diagnose, prevent, monitor, or treat a disease or injury
- Investigate, replace, or modify a part of the body
What is a biomaterial?
A biomaterial:
- is made from a natural or synthetic material that can be engineered to help itself.
- can be introduced into the body as part of a medical device or used to replace an organ
- can be temporary or permanent
What are biomaterials used for?
Medical Devices
What is the pro and con of Synthetic Biomaterials?
Good: They are easy to make and exactly the way you need it to be.
Bad: Sometimes the body does not like them.
Stuff to know
Biomaterials can take many forms to support new tissues to grow
Some biomaterials are soft and jelly like and can be injected into the brain or heart.
