Rapid Prototyping: 3D Printed Bicycle

Product.005.jpeg

Bicycles are not designed for electronics attachments

Observed that makeshift solutions and after market products are used to attach electronics onto bicycles.

A bicycle designed for electronics could utilize conductive filament

A combination of conductive and carbon fiber filament could be used to 3D print a bicycle frame that can power and allow data communication between snap-fit electronics attachments.

Finding the right snap-fit profile is critical for user experience

Prototyped different snap-fit geometries until one was found that not only was easy to attach and detach from the frame, but also had a holding strength enough to withstand bicycle riding forces.

Attachments can be instantly connected to power and data

Designed a bicycle frame that could power and allow data communication between electronic attachments by having exposed power, ground, and data lines on the surfaces of the frame and the attachments.

The final design can introduce many new features to the bicycle

3D modeled a bicycle that uses attachments to track pedaling for helath monitoring, create a turn signal for enhanced safety, and keep bottled water cool for refreshment.

Engineering: Wearable Oxygen Concentrator

Product.006.jpeg

Oxygen therapy devices currently on the market have many shortcomings

Existing oxygen concentration devices are visible signs of disability. They provide therapy at a pre-set flow rate and the patient decides when to start or stop the device.

Engineering an oxygen therapy device that can run by itself

Developed the hardware and control systems algorithms for an oxygen therapy device that uses health monitoring sensors to deliver personalized treatment to a patient with respiratory disease.

Design Research: Dental Drive Hearing Aid

Product.007.jpeg

Arthritis can cause middle ear hearing loss

Osteoarthritis can attack cartilage in the joints of the middle ear, resulting in hearing loss that can not be fixed by normal air conduction hearing aids.

Product.008.jpeg

The only treatment for middle ear hearing loss is highly invasive

Patients who get a Bone Anchored Hearing Aid, currently the only treatment for middle ear hearing loss, must go through Craniofacial surgery. 

Product.009.jpeg

Some arthritic patients have difficulty managing hearing aids

Some arthritic patients have difficulty inserting and removing their hearing aids, replacing the batteries, and cleaning the device, due to degraded dexterity. 

Product.010.jpeg

Dental drive hearing aids are non-invasive but expensive

Middle ear hearing loss can be treated by non-invasively by attaching a resonator to the teeth, however manufacturing a custom device for each patient makes this alternative far more expensive.

Product.011.jpeg

A moldable dental drive hearing aid could reduce unit costs

Designed a mass-manufacturable, moldable dental implant to serve as a bone-conduction hearing aid, significantly reducing the cost of treating middle ear hearing loss in a non-invasive manner.

Embedded wireless charging keeps the device running all day

The device utilizes a flexible aluminum-ion battery that can be recharged wirelessly using a solenoid micro coil. A wireless charging pad would be placed under the pillow, safely recharging the hearing aid while the patient sleeps.

3D Modeling: Wearable Bicycle Lock

Product.014.jpeg

A combination bicycle lock and helmet makes riding simpler

Many cyclist must remember their helmet and bicycle lock key to ride their bikes. By designing a combination bicycle helmet and lock, these items would always stay with the bicycle and would never need to be remembered.
