This document summarizes Derek Hilleren's engineering internship from May 2014 to August 2014 with CNH Industrial. It details the goals of taking part in the full design process, applying classroom knowledge to real-world problems, and focusing on energy conservation. It provides summaries of two projects: modifying the battery box mounting design to reduce parts and standardizing the design, and validating the performance of alternative bumper suppliers through testing. The internship helped improve Derek's professional skills like time management, project management, communication, organization, and problem solving while providing insight into the work of design engineers.

 Take part in each step of the design process and learn from a talented team of
engineers. Work with the team to solve problems and be a part of the solution
with opportunities to implement my ideas.
 Apply my engineering “book knowledge” to real world problems to help find
solutions. An opportunity to see how and where my knowledge can be applied
in the real world.
 Design a part/ system/ assembly with energy conservation being a high priority.
Energy conservation can be achieved by looking at:
 Reducing
 Reusing
 Recycling
Internship Goals

 Summary:
• Resolve the battery box mounting issue observed on the 3340 while keeping
mounting hardware to a minimum and keeping a commonized battery box among
all models of sprayers.

 Challenges
• Keeping a communized battery box among all sprayers
• Sizing the tabs correctly via hand calculations in order to withstand the specified
stresses
 Learning Outcomes
• Experience the design process and how such a small change can drastically
improve the product and manufacturing efficiency
• Opportunity to work with manufacturing and implement this change on the assembly
line
• Applied my engineering knowledge with static and dynamic stress calculations and
compared my results to FEA results

 Summary:
• Alternate supplier part validation
 Validate weather or not the jounce and extruded bumpers from an alternate supplier meet
or exceed the performance of our current production bumpers
o Conducted extensive research on rubber properties in order to devise a procedure with testing
parameters that would give us definitive results
o Work with a testing facility to conduct testing based on my testing procedure
o Participated in design review meetings in regards to testing fixtures designed for this project
