TagLug: Luggage Scale, Tracker, and Tag

Overview

  • Designed, coded, and fabricated a multi-functional luggage tag with a built-in display, scale, and GPS tracking device

  • Built injection-moldable outer casing in Solidworks to hold Arduino-programmed electronic components

  • Collaborated with Duke Masters students to develop supply chain strategies, package design, pricing, and product aesthetics


Description

One out of five people in the United States find out that their baggage is overweight at the check-in counter every day, paying an average of at least $45 in overweight baggage fees. In 2018 alone, 21% of US Travelers exceeded their luggage allowance and $1.25 billion worth of baggage was potentially lost or stolen. We hope to reduce anxiety caused by unnecessary and unforeseen fees and lost or stolen baggage. The design goal of this project is to create a product that can act as a luggage tag, scale, and tracker, while remaining portable and durable enough to remain on the exterior of luggage.


We created TagLug, which is a universally integrated device that helps people save money while also providing peace of mind when traveling.

TagLug is a multifunctional luggage tag with a built-in scale and GPS tracking device. The product is lightweight, durable, ergonomic, and easy to use.

Product Development of Custom 3D Printed Medical Protective Devices Using Digitally Fabricated Lattice Structures
Fall 2021

Overview

  • Researched the strength properties of lattice structures to reduce size and weight of products while improving performance

  • Modeled in Rhino and nTopology to prototype shin guards for user testing with the Duke Men’s Club Soccer team

Description

The goal of this project is to explore the use of lattice structures in custom 3D Printed Medical Protective Devices.

Specifically, the aim was to create a pair of shin guards that optimize for comfort, energy absorption, protection, and weight reduction. The basis of this research is from a Duke Senior Design Project from 2020, which discovered the optimal properties of additive manufacturing using EPU40 in a gyroid lattice configuration. Shin guards were chosen for their wide use and basic design.

Please see the slides attached below for the final presentation.

Temperature-Controlled Prosthetic Skin for Medical Manikins

Fall 2019

Overview

  • Designed device to simulate feverish conditions by developing skin-like resin with material properties to evenly distribute heat

  • Iterated on interactive device based on client feedback

  • Modeled casing in Solidworks for Arduino electronics


Description

Currently in healthcare training settings, most manikin simulators do not exhibit realistic feverish symptoms such as changes in body temperature or changes in appearance. This lack of lifelike features hinders the practice of comprehensively diagnosing health conditions. We successfully made a realistic skin patch that has the elasticity of human skin and can be remote-controlled to heat up to 5 specific temperatures between 34°C and 40°C within 5 minutes, simulating feverish symptoms.

Injection Molded Happy Meal Toy

As part of Engineering Innovation, my project team was tasked with creating a Happy Meals Toy that is low cost and safe. Using SolidWorks, we created a toy airplanes based on the Disney Pixar movie Planes. Each airplane is created using 4 different injection moldable parts including the propeller, the wings, and the upper and lower body. Our toy planes are made out of ABS plastic that is low-cost yet sturdy and safe, and each character in our collection is decorated with its own vibrant color scheme. In manufacturing, each toy costs around only 38 cents to make including labor and machine production, and because of our easily injection-moldable design, production duration is only 5 to 10 minutes –– making for a very quick turnaround time.
