Fall 2023 Senior Design Projects

Turning Wheels

Objective: This project goal is to allow wheelchair users with upper extremity amputees to live more independently and provide the option of a non-electronic based wheelchair.

Team Members:

• Faisal Alomar
• Shelby Gain
• Mac Stoffel
• Connor Zastrow

Advisor: Jacob Rammer, Assistant Professor Biomedical Engineering

Findings: A person’s mobility and freedom to move around, specifically walking, is often taken for granted. A study of US residents in 2005 estimated that more than 1.6 million individuals have undergone at least one amputation. This population is anticipated to more than double by the year 2050 due to the prevalence of dysvascular disease, diabetes, trauma, and cancer. Leading to many individuals globally being wheelchair-bound. However, what if there was a way that people could regain this freedom and mobility to move independently again without having to use a powered/electric wheelchair. 

The MPAWA (Manual Prosthetic Arm Wheelchair Attachment) is a manual prosthetic device for wheelchair-bound arm amputees who want to manually propel themselves in a wheelchair. This device is filling a hole in the manual wheelchair market as there are no manual wheelchair devices on the market for wheelchair-bound arm amputee(s). This device will work anywhere that is wheelchair accessible and has all the functions of a normal manual wheelchair. The MPAWA connects the patient’s upper extremity amputation to the wheelchair’s wheel directly similarly to an elliptical. 

Moving forward this device needs more testing on the research and development side and overall stronger materials before going to market as this prototype device was mainly to show the general concept. Overall the design and final device prototype met the required specifications but could be improved in the future.

Innovative Infant Aid

Objective: The aim of our project is to decrease the risk of infantile asphyxiation through a self-leveling smart bassinet, providing peace of mind to first-time parents about their child’s safety.

Team Members:

• Erik Hanson
• Yiwen Qin
• Josh Schneiger
• Lorryn Wilkinson

Advisor: Jacob Rammer, Assistant Professor Biomedical Engineering

Findings: The objective of our project was to design a device that serves as an effective solution to keep an infant between the ages of 0-6 months in a supine position while sleeping. One of the leading causes of death for an infant between 0-6 months is sudden unexpected death in infancy (SUDI). The AAP recommends that infants sleep wholly on their back during sleep. To reduce cost, the device was scaled down to better observe the reaction between the top of the mat and motor units. The top pad was designed with pressure sensors underneath to capture the movement of the baby. This information is then sent to an Arduino microcontroller which controls the motors based on the infant’s movements. If the sensors detect a significant change in pressure from the beginning stages of rolling over, the pad then adjusts the level to promote the infant back into a supine position. 

The safety of the child is the device’s number one priority, so this aspect will be under constant revision by the team. With more time, the device can be more sensitive with additional testing to provide greater safety features.

Team Members:

• Kaitlyn Donley
• Andrew Miller
• Bridget Ohme
• Ricky Ortega

Project Advisor: Mohamed Yahiaoui, Senior Lecturer Mechanical Engineering

Industry Mentor: Joseph Friedli, Hellermann Tyton

Project Findings: A reusable tool was designed to stretch and apply cold shrink tubing, made of ethylene propylene diene monomer (EDPM) rubber, in place of a plastic ripcord. After meeting with the sponsor, functional requirements for the design were recorded and critical to qualities (CTQs) were decided based on that list. The CTQs are; the tool can apply cold shrink at 2-in. lengths, can stretch cold shrink to twice its diameter for application, easy to use, and comfortable to hold. To measure the ease of use and comfort of the tool an internal team survey was conducted, where an average of 4/5 (5=excellent) is a success. Multiple designs and prototypes were made; however, the design inspired by snap ring pliers was the best option to further develop. The final prototype was made from polylactic acid (PLA) filament, so the design had to be tested using CREO parametric simulation with the desired material properties. The material for the tool’s production was decided to be chrome vanadium steel, which is a common tool steel used for wrenches and pliers. Based on the results, the design needed to have more material around the base of the pins that stretch the EDPM rubber. This is because there was a large deflection of the pins when forces were applied. The design also had a large distance between the handles. Ease of use and comfort were given a successful 4/5 average. Suggestions to add thicker bases at the pins and decrease the handle’s outer distance were made to have a functional tool.

Heat Set Insert Rig

Objective: The goal of this project is to create a heat set insert rig that’s adjustable to the operators needs. It will hold a soldering iron that can then press a heat insert into a 3D printed part.

Team Members:

• Nathan Bezier
• Matt Moen
• Gunnar Peterson
• Brendan Tan

Project Advisor: Mohamed Yahiaoui, Senior Lecturer Mechanical Engineering

Industry Advisor: Jordan Nowak, Engman-Taylor

Findings: 3D Parts Unlimited, a service by Engman-Taylor, is a Wisconsin-based company that provides 3D printing services. One of the types of 3D printing they provide is carbon fiber reinforced prints, which allows
assembly of parts using heat set inserts. The process of applying these inserts involves using a soldering
iron to heat up and push a threaded insert into the workpiece. They have been doing this manually and
were looking for a custom-built heat set insert rig, which is easier to use and produces more accurate
results.

After speaking with a representative from the company, the team created a list of critical-to-quality items the rig needed to have. These consisted of being able to rotate the plunge and solder 0° – 60° ± 3° and plunge a maximum depth of 1”, keeping the solder within ± 3° of the angle chosen, having a safety tube that prevents a user from getting within 0.25” of the solder tip, and the total cost being under $200. The team worked to create a product that met these requirements and were successful in their goal. The rig that was produced allows for more consistent results, and a safer application of
inserts for the use.

Life Cycle Tester Failure Mode Detection

Objective: The goal of this project is to design and implement a method of detecting failure modes for HellermannTyton’s equipment used to test the life cycle of their cable tie adjustment tools.

Team Members:

• Noel Cramer
• Nick Evert
• Daniel Schimp
• Evan Stickles

Project Advisor: Mohamed Yahiaoui, Senior Lecturer Mechanical Engineering

Industry Mentor: Aaron Sherman, Hellermann Tyton

Findings: HellermannTyton is responsible for manufacturing and supplying products for fastening, fixing, identifying, and protecting cables and their connecting components. To maintain the company’s signature level of quality, rigorous testing is conducted on their products.

One method employed by HellermannTyton involves subjecting application tools to millions of cycles using thousands of feet of cable and an automatically actuated testing box. However, the company has encountered issues with the testing system, experiencing failures such as feed shutdowns, spool tangles, and dancer arm malfunctions. These problems often go undetected, resulting in system breakdowns and significant losses of time and money. Consequently, HellermannTyton has sought the development of a new failure detection system capable of identifying issues and shutting down the system before any damage occurs. To address these challenges, a design was developed that utilizes the increasing tension in the testing cable during a failure to lift a traveling roller and activate a limit switch, thereby shutting down the system. This final design emerged after comparing initial designs using Pugh Matrixes, developing a prototype, conducting tests, and creating CAD files along with fatigue life calculations to ensure the longevity and quality of the final product. The implemented design accurately detects specified failure modes and communicates with the testing box and motor to initiate a shutdown.

Roller Manufacturing Process Automation

Objective: To automate a collet clamping and release detection process in a tube rolling machine for Grob Inc, a cold forged products and bandsaw manufacturer located in Grafton, WI.

Team Members:

• Matt Becker
• Nick Fiala
• Jordan Helgeland
• Bryan Wendt

Project Advisor: Mohamed Yahiaoui, Senior Lecturer Mechanical Engineering

Industry Mentor: Andre Deriaz, Grob, Inc.

Findings: The senior design team working for Grob Inc. set out to automate an industrial process involving automatic clamping and machine state detection to eliminate the need for a machine operator to perform repetitive tasks. The team had the opportunity to learn a lot about real-world processes of industrial machinery, and how to successfully encounter a problem, come up with a solution, and implement it. A pneumatic clamp was selected to clamp and unclamp a workpiece and it was mounted alongside a force sensor to detect a particular machine failure state. The solution proposed by the senior design team will enable a repetitive daily task to be automated, which is projected to save Grob Inc. over $10,000 per year – a return on investment of about one year.
