Project Overview

The focus of this project is to design a childproof mechanism for a vacuum-sealed cannabis bag. The team is working closely with the project’s sponsor, WorldPak, to make sure that the design is successful and meets the specified criteria. The specified criteria are as follows: children will be restricted from the contents within the bag, the closure mechanism must be sturdy enough to be reusable for at least 100 uses, the closure mechanism must be a unique design in order to obtain defendable intellectual property, the closure mechanism must be easy for the elderly to use, the closure mechanism must minimize use of rigid material, and it must pass the 16.CFR 1700.2 testing procedure for special packaging. How well these criteria are met will determine the overall success of the design. Creating this mechanism is important because children are gaining access to pharmaceuticals and marijuana products, which is causing accidental poisonings. This issue demonstrates a need for improved childproof zipper mechanisms which Simply Safe aims to address.

Proof of Concept

The childproof zipper mechanism that Simply Safe will be developing is a project within the Packaging Industry.  The Packaging Industry has a few huge, multi-billion dollar companies such as 3M, and many smaller companies such as our sponsor, WorldPak LLC.  For this project, we will be focusing on a smaller subset of competitors that are focused on developing childproof vacuum bags, specifically for the cannabis industry.

In order to prepare for entry into this industry, we have met for lunch with our sponsors in order to discuss the various options currently on the market, as well as their limitations.  The engineers at WorldPak helped to outline their various design constraints, as well as provide project objectives to help us more fully understand the requirements of the project.  We were also able to take a tour of their manufacturing facility in order to familiarize ourselves with the machinery that we will be using through the design process.

A few key competitors in childproof vacuum bag industry are Dymapac, Sierra Bags, Stink Sac, and Clearbags.  These bags range from about $0.50 to $1.00, so efficient use of materials and manufacturing optimization is a huge factor in the economic feasibility of a design.

These bags are typically bought in a “case” that includes 50-5000 bags depending on the customer needs.  As the total quantity goes up, the price per bag decreases drastically.  The typical customer is a Dispensary Shop owner who tends to buy in high quantities since all products that leave their shop need a childproof exit bag.  While some bags are available online or on Amazon, the typical channel of distribution will be for the Dispensary to place an order with the packaging manufacturer directly.

Meet the Team

Adrian Cesena

My name is Adrian Cesena and I am from San Diego, California. Outside of school and work, I hold a position in his fraternity for coordinating and setting up events. This means I am in charge of communicating with our national advisors, contacting outside sources, filling numerous forms and contracts and lastly managing all events to ensure they run smoothly and successfully. Another extracurricular accomplishment I have done was creating and becoming the founding president of the Manzanita Boating Club through the University of Nevada, Reno. My internship is currently switching into a new ERP system. In this process, I was in charge of programming the process for how sales representatives will configure custom concrete parts. I needed to analyze how he could include all of the sales representatives needs and include them into the coding process when adjusting the ERP system. This ties into the manufacturing process of building the concrete part itself, so I needed to reach out to the construction plants to obtain data for labor and machine deprecation/labor to include it in my formulas. Lastly, I needed to consider some of the accounting basics for products that are already built and yarded. I decided to use the average cost method, which gave him better results.

After graduation, I would like to work for a start-up company and help grow that business. This may be riskier when compared to working with a large corporation, but the reward is worth the risk if the start-up company becomes successful.

 

 

Bryce Lewis

My name is Bryce Lewis and I grew up in Roseville California.  My current goals include graduating with my BS in Mechanical Engineering and a minor in Business Management.  In the future, I intend to travel and save money for a year before beginning graduate school pursuing my MBA.

The most challenging engineering project I have been a part of has been a top-to-bottom overhaul of the engineering process during my internship as Jensen Precast.  With the introduction of a new ERP system, I was involved in determining the best way to integrate all of the calculations, drafting, and proper verification into the new united system.  I provided documentation for the new process, helped build a new engineering Wikipedia, and created interactive manuals to help bring everyone in the company up to speed.

Outside of school and work, I help organize and host an annual mountain bike race with Nevada Cycling at Sky Tavern.  We hold four separate events on four different courses, which require extensive organization of volunteers, collaboration with the land owners, and cooperation with local governing bodies.  In the past year, we had issues with the local government and had to plan, build, and perfect a completely new course.  With the help of the landowners, we were able to build an entirely new piece of trail that was fun, safe and racable over the course of two weeks.  Aside from the difficulty building the courses, we also plan the logistics of running 100+ racers through four races in two days, which is quite a difficult task.

 

Isa Sirbegovic

My name is Isa Sirbegovic and I’m originally from Newport Beach, California. I am currently working towards graduating with a Bachelor of Science degree in Mechanical Engineering with a minor in Renewable Energy. Once I graduate I plan to travel abroad for a bit and explore various options for graduate school. I currently plan to attend graduate school to receive a Master’s in Business Administration.

The most challenging engineering project that I have been involved in was for my engineering internship at Dragonfly Energy. It involved working with an interdisciplinary team to build, wire, and develop programming for automated welding systems. This entailed tackling design concept problems, developing a functioning proof of concept, working to reduce the overall cost of material, and meeting weekly goals to stay on track for fabrication of the systems.

During my academic career, I have been able to improve upon my ability to work in a team and effectively tackle a variety of non-technical tasks. In addition to this, I have a greater understanding of engineering disciplines and how to apply them to assist in complex problem solving.

Outside of school and work, I have been heavily involved in volunteering for a nature center. I have taught a variety of children’s wildlife classes, led nature hikes, and have handled and cared for native animal species. It is a non-profit organization and depends greatly on volunteers and donations to be able to maintain the facility and have classes. I worked closely with the manager to evaluate the metrics of what classes and animals attracted the largest audience. Using this information and additional research, I organized creative and fun programs to help bring in more donations and visitors to the nature center.

 

Devin Harrill

Devin Harrill was born and raised in Carson City and will be graduating in the spring of 2019 with a Bachelor of Science in Mechanical Engineering. In his free time, he enjoys being outdoors and has worked as a snowboard instructor for the last six years. During his academic career, his most challenging engineering project was the K-12 service learning project he did in his junior year. This project helped improve on many of his skills including, team communication, time management, and problem solving. After graduation, Devin plans to stay in the northern Nevada area while pursuing work in the automotive design field.

 

 

 

 

 

 

Dillon Wilcox

My name is Dillon Wilcox and I am currently in my last year studying mechanical engineering at the University of Nevada. In my life so far, I have had to overcome many challenges. These challenges range from schooling, work, social, and athletic priorities. All of these challenges have shaped who I am today. Regarding schooling, my most challenging engineering project that I have been involved in was making a hovercraft during my freshman year. This project required good time management, team communication, item prioritization and the ability to fail. It also taught me how to be detail oriented and to distribute jobs based on team member’s skills. Additionally, I continued to acquire skills because of the different organizations I am involved in. I have been in a fraternity for three years now and have held executive positions such as recruitment chair. This position helped me stay positive and excited in any situation, required me to stay in contact with over 200 potential new members, and gave me the opportunity to facilitate events for a week strait averaging about 70 individuals per day.  I am also very proud of the leadership positions I have worked towards and achieved here at the University of Nevada. Currently I am involved in student government and am one of the Senators of the College of Engineering, which has taught me how to reach out to my constituents and use my voice to work for what they want. This position also requires me to sit on different committees where I sit on the committee of Budget and Finance and the committee of academics. The committee of Budget and Finance distributes a budget of 2.5 million dollars and I help with the allocation of that money. Additionally, I worked as an orientation guide this summer teaching over two thousand students about the university. This job has made me very aware of the campus and all of its entities. I now bleed blue and silver and am very proud to have gone to school at the University of Nevada.

My main goals currently are to network as much as possible during my last year of college and to use my student government position to leave the College of Engineering in the best possible place for the upcoming years. After I graduate, I plan to get a job after that offers a lot of potential for learning within my field.
