Arthritis
Concept Evaluation
We needed to decide on a final design. To do so we evaluated the pros and cons of choosing a stationary devises versus an arm device.
Basis of Comparison...



Arthritis causes the loss of movement in the joints.
Our task is to create a device that enables people with Arthritis to open their pill bottles.
Our device has to dispense medicine.
The loss of movement in one hand will not be an impediment for our clients to have access to their medicine.
Lack of time, materials, and technology were all constraints in this project.
Problem Statement
Pill bottle base
Cap grip/ twist
Interface
Pill dispenser
Preliminary Design
Brainstorming
Function
Initially, we brainstormed incorrectly by jumping straight into the design stage
Robo Arm
Our first design was a robotic arm.
We expanded on the idea and created multiple versions.
Our first idea contained numerous flaws.
Structured Brainstorming
Functionality
Safety
Materials
Look
We started brainstorming by creating brainstorming categories involving our product:
Ideas!
After brainstorming the functionality of the project and safety, we began brainstorming more ideas.
Rotational device
Compact yet fit numerous pill bottles
Materials
Final Design 3D Concept
Realistic
Easier to use
User friendly
Outer Shell: Stainless steel
Main device: Plastic
Claws: Titanium plating with rubber sole
Buttons: Soft plastic with LED lights on the inside
Internal Gears: Steel
Pressure Sensors
Sliding Door: Glass

The inflammation of the joints in the body
There are over 100 forms of arthritis
Osteoarthritis (OA) is the most common type of arthritis.
OA is the degeneration of cartilage in the joints, it causes stiffness and pain.
OA affects about 27 million People in America.
Causes 9,367 deaths each year in the USA alone.

Given More Time...
Add a blade for cutting pills
Try to make device more portable
Made a physical model
Included more safety measures
