Biomedical Engineering Project
Introduction
Have you ever felt that you need any new inventions or innovations? Well, we, the Global Engineers, are gladly here to help. Our brilliant team consists of Micaela, Teg, Marie, and Brandon. Our main goal is to solve any problem you have. So, let's get on with today's problem.
Problem
Sam is a ten-year-old boy with Cerebral Palsy. Because of his condition, he has no fine motor control in his right hand, causing him to need a custom writing utensil so he can write legibly. So, he and his therapist have been looking for someone that can take this job, and we, the advanced 6th graders from Cashman Middle School (a.k.a The Global Engineers) are prepared and ready to go.
Constraints
Our constraints consist of:
Time: We have eight weeks.
Parts: Our design needs a minimum of four parts and a maximum of eight parts.
Solutions
We generated four solutions, but only one was chosen because of how it met our constraints.
The First Design
Teg's design consists of a pencil with hooks to grab onto Sam's fingers. The hooks have rubber around them and it is made out of metal. This design was chosen because it best fits the criteria, it is safe for Sam to use, and it can be easily made in eight weeks.
The Third Design
The Second Design
Micaela's design was a regular lead pencil with a mold able material similar to Play-Doh. But, once it was molded, it would stay that way, but in a rubber material. This design wasn't chosen because if the material dries, you can't fix it again. This is a problem because if Sam needs to fix the rubber material, he can't because the material is already dried. Also, you can't display something mold able on the computer program we are using.
The Fourth Design
Brandon's design consists of a pencil covered in Velcro. It comes with a glove also covered in Velcro and it allows for better/improved control. The reason we didn't pick this design is because it would have taken too many parts and would not have been finished in eight weeks.
Our Team Design
Our designed pencil should be selected because it is very well constructed. This writing utensil also has a comfortable grip. Overall, our design should be chosen because of the use and features of it.
Marie's design involves a rubber-gripped pencil, a rubber glove, and a hook that grabs onto Sam's wrist. The pencil grips to the glove and the hook steadies the wrist. The reason why this design wasn't picked is because it had too many parts and could not be finished in time.
Cerebral Palsy
Cerebral Palsy, the disease that Sam is suffering from, is a disease in which a body part loses its fine motor control, or the ability to stay still, and starts shaking. This disease gives him a disability to write.

Production
This design should be put in production
because there is not just one client throughout the whole world that is suffering through this problem; there are thousands more that can benefit through this design. Plus, this design will only cost $17.75 because of all the materials. Overall, this design could be the next big thing for the people in the world of Cerebral Palsy.
Research
Our research consisted of Cerebral Palsy (a disease), what can be done to design a pencil for someone with Cerebral Palsy, and other facts about this disease (what can cure it, etc.)
What Can We Do
We had to carefully think of what we could do because the client is looking for something that will solve his problem and be safe for him. This leads us to the constraints in which the design that is chosen had to meet.
