Week 15: Halfway to the Finish Line!

The LineTech and FPL team after the System Level Design Review.

LineTech came back from a restful Thanksgiving break with full steam ahead. With valuable feedback implemented from the peer review, we course corrected and clarified some important aspects of our project and presentation. Final improvements to the SLDR report were made with FEA models, efficiency calculations, and preliminary testing protocols. Clarifications of the problem areas were made in our presentation’s problem statement. 

After working hard on our material, SLDR day went by without a hitch. The team enjoyed networking, participating in the interactive keynote, and watching fellow groups’ presentations. Once the presentations concluded, the best project liaisons ever, Natasha, Olivia, John, and Justin (in spirit), took the whole LineTech team out to dinner at Dragonfly Sushi & Sake Company in downtown Gainesville. At dinner, we celebrated the team’s successes and discussed the future plans for the project over delicious sushi.

The LineTech team would like to end the semester on a high note and wish all IPPD teams a peaceful winter break and good luck in the coming semester. Happy holidays! 

Week 13: Busy Bees!

LineTech after the peer review SLDR.

This week started off strong with our System Level Design Review (SLDR). After wrapping up our draft document and presentation on Sunday and Monday, we presented on Tuesday and received valuable peer feedback, especially around the frame design of our device. Later in the week, some team members headed to the prototyping lab to cut into the aluminum stock we received from FPL, confirming that it is suitable for constructing our spool. 

On Thursday, we met with Justin, our liaison from FPL, over lunch at The Flying Biscuit Café. We shared the latest version of our SLDR and gained insightful feedback, including advice to strengthen our testing processes by accounting for higher temperature maximums and wind speeds. With Thanksgiving break ahead, next week will be a rest period before we return to continue refining our design. Wish us luck as we move forward! 

Week 12: Design Refinements and Testing Realignments!

This week, LineTech made meaningful progress on our System Level Design Review (SLDR) report, building on the insights gained last week during Prototype Inspection Day (PID) and our disassembly of the FPL-provided hoist. The hands-on teardown offered valuable insights on real-world component integration, informing both our documentation and design decisions. 

During PID, several questions emerged regarding our testing strategy. In response, we began outlining feasible procedures to validate system performance. At the forefront of our testing plan is a high-capacity Universal Testing Machine, which we’ve identified as a strong candidate for evaluating the performance of our subsystems as well as final device. We also defined preliminary methods for assessing the efficiency of individual components which are essential for ensuring reliable system performance. 

The lessons from PID and the hoist analysis resulted in updates to our CAD models. We also conducted efficiency calculations for some key subsystems, helping us better understand the performance trade-offs within our design. 

In the coming month, we’ll be focused on refining subsystem details in preparation for the upcoming peer review. This milestone will be instrumental in providing constructive feedback as we continue to iterate and improve. 

Week 11: Prototype Inspection Day and Progressions!

The team at Prototype Inspection Day.

What a week! On Tuesday, November 4, 2025, we presented our prototype and subsystem plans to faculty experts in the Rion Ballroom at the Reitz Union. The experience was incredibly rewarding, providing us with valuable feedback on both our technical concepts and presentation skills. One key takeaway was the need to develop a safe and practical method to test our hoist, which must withstand up to three tons of force. Identifying a testing solution will be a major focus as we move forward. We’d like to thank all the faculty members and former IPPD students who took the time to attend our presentation and share their insights.

Later in the week, we disassembled a ¾-ton manual hoist provided by our liaisons. This hands-on activity gave us a better understanding of the hoist’s internal mechanisms and friction brake system, which closely align with aspects of our own design. Examining the ratchet-and-pawl and braking components also helped us identify parts we may adapt for our prototype to help reduce costs.

Looking ahead, our team is applying the lessons learned from both the PID feedback and hoist disassembly to refine our design. We are updating our CAD models, conducting stress analyses, and continuing to ensure that safety and functionality remain top priorities.

Week 10: Prototype Preparations!

Prototype model for demonstration at PID.

Onward and forward! With Prototype Inspection Day (PID) coming next week, the team has been busy planning, 3D printing, and assembling our first prototype. The goal of our prototype is to test the concept of using a friction brake to reverse the direction of the spool to sag a line. We are using 3D printed parts along with twine and a motor to prove that our idea can both tense and sag a specified weight. We look forward to presenting our prototype to the judges and receiving any feedback that we can then use to improve our concept.

The team also plans to bring subsystem ideas to PID to receive additional feedback from the judges. Included are the frame and rope guide subsystems. This is a great opportunity to get suggestions from faculty specialists, and we are planning on making the most of it. Our coach, Dr. Kimberly Stubbs, has been an amazing mentor thus far in providing guidance and support throughout the process. At our coach meeting this week, she provided several forms of insight that we have been working to implement as we’ve progressed.

Looking to the future, LineTech intends to use feedback given at Prototype Inspection Day to further our concept and make improvements. SLDR is coming up in the near future and we plan on continuing our path towards success.

Week 9: PDR Presentation!

On Monday, October 20, 2025, the team traveled to one of FPL substations in Venice, FL, to present our Preliminary Design Report (PDR) to our project liaisons. After an early morning drive from Gainesville, we met our liaisons in person and successfully presented our progress. We received valuable feedback, including a key recommendation to design for a 3-ton load instead of a 9-ton load, as it’s more representative of typical field applications. This adjustment will help us create a more practical and effective solution for linemen.

Following the presentation, we toured the substation and got hands-on experience with various hoists and conductor grips used in the field. Seeing and handling these tools provided a clearer understanding of the real-world challenges linemen face. Afterwards, our liaisons kindly treated us to lunch at a local waterfront restaurant, where we enjoyed great food and conversation about both work and life. Lastly, the team got the opportunity to spend some time on the white sand beaches of Sarasota before the journey back to Gainesville.

We’d like to thank our liaisons — Natasha Zbib, Justin Kissel, Olivia Meingasner, and John Redmann — for their continued guidance and support. This process would not be possible without them, and for that we are forever grateful. Looking ahead, we’ll refine our 3-ton automatic conductor hoist design and continue developing our prototype for Prototype Inspection Day on November 4. Exciting progress is on the horizon for LineTech!

Week 8: Demonstration and PDR Preparations!

The team at the live demonstration in Gainesville!

This week, LineTech got the opportunity to witness a live demonstration of how transmission lines are currently tensed and sagged. One of our liaison engineers, Justin, and lineman chief, John, were gracious enough to travel to Gainesville to demonstrate the process and answer our questions. The demonstration was incredibly beneficial to the team as it offered a visual to the process we are trying to automate and allowed us to see flaws in our current design. The team was able to simulate being a lineman, putting on the heavy duty gloves and working the hand ratchet along the makeshift conductor line.

Using the gained information from the demonstration, we went back to our PDR to review updates that needed to be implemented. One of the main points that needed to be added included a feature that would loosen the transmission line instead of only tensioning it. The team looked into reversible winches and used that theory to include a ratchet and friction brake mechanism. Working together and with out coach, changes were made to the PDR document and presentation.

Looking to the future, we are traveling to Venice, FL on Monday to give the PDR presentation to our liaisons and other FPL employees. We are looking forward to meeting everyone in person and presenting our work thus far. Once the presentation is complete, we will await approval of our current concept, and if everything goes smoothly, we will begin the prototyping process.

Week 7: PDR Peer Review!

A look into our Friday team meeting explaining the math behind our concept.

This week, LineTech took to the big screen to present our Preliminary Design Review (PDR) to fellow IPPD teams, coaches, and staff. It was a challenging task, but we delivered a strong performance that showcased our hard work and preparation.

After conducting a mock run of our PDR presentation, we received valuable feedback from our peers that we’ll apply to our upcoming presentation with FPL. One major takeaway was the need to expand on our concept generation process. Up to this point, our concepts focused mainly on subsystems and their requirements, rather than specific components. We also realized that including more detailed numerical justifications for our component selections would strengthen our presentation.

To address these points, the team developed an Excel model that allows us to input component specifications and generate corresponding project requirements. This tool will help ensure that our design decisions are backed by solid data moving forward.

Next week, we’re looking forward to meeting with one of our liaisons, Justin Kissel, and observing the operation of the current hoist system. The demonstration, as well as past research, will allow us to come to the PDR presentation prepared and confident.

Week 6: More and More Concepts and Brainstorming!

A glimpse into our Wednesday team meeting!

LineTech spent the past week rigorously engaged in concept generation and solution refinement for our sponsor’s problem of automating conductor tensioning. We performed in-depth research, gained a clearer understanding of the line tensioning process, and, critically, identified limitations within our initial concepts. This process of elimination led us to define our winning concept: a system using a motor, a pulley system, and reduction gearing to achieve our end goal. Following our team meeting on Wednesday, we divided into specialized system architecture groups to focus and concentrate our research and development efforts.

A significant design limitation became clear after we met with Dr. Stubbs on Monday: the excessive amount of rope or chain that our leading concept would require to function. This forced us to begin a critical assessment of necessary design compromises. This balancing act between performance metrics—specifically current draw, battery life, and overall weight—remains our biggest challenge. We have crucial work ahead to better define our limitations and determine if a pivot is required before the Preliminary Design Review (PDR).

We have two major events scheduled that will shape our path forward. First, on October 17th, our liaison engineer, Justin Kissel, will provide a demonstration of line tensioning. We anticipate this will offer key insights into the practical implementation of our solution. Second, the peer review PDR will serve as a vital “dry run,” ensuring we have all the information necessary to convey our technical ideas successfully. We plan to use the weekend before the official PDR to iron out the final details for a comprehensive and holistic presentation.

Over the ensuing week, our efforts will be highly focused. We are committed to polishing our final concept and producing proper engineering drawings. This must be accompanied by a solidified prototyping plan and the initial development of a comprehensive Bill of Materials (BOM).

Week 5: Designs, Costs, and PDR!

The product of our brainstorming process and bad sketching from our Thursday meeting.

Inclement weather incoming! Not from Mother Nature, but from LineTech’s brainstorming. We successfully navigated this demanding week of design generation and documentation. Our primary focus has been conceptualizing and generating solutions for our automated conductor hoist, alongside refining our Preliminary Design Review (PDR) report for submission on Friday.

Following our meeting with Dr. Stubbs on Monday, we recognized the tight timeline for conceptualization and prototyping after she pointed it out. This prompted us to kick things into overdrive. A minor adjustment we made was to more accurately depict dates and increase the readability of our Gantt chart. We held a major brainstorming session on Wednesday in the Reed rooms, where we individually presented initial ideas. We soon realized our ideas converged, so we moved things over to the whiteboard as shown in the image and began ironing out more details of that specific design. This concept is a promising one that we plan to continue to research, especially after validation from our liaison engineers. We will continue to generate and compare additional ideas next week before confirming a final design. We are also looking forward to more specific information from our liaison engineers.

Looking ahead, we plan on focusing our efforts on researching components for designs and performing the necessary engineering calculations to ensure our design meets all required specifications. With this, we’ll be able to determine the best design for use in our final product.

Finally, we are excited to announce that we have coordinated our PDR presentations with FPL for October 20th in Jupiter, FL. We will also have a demonstration on October 17th to see in person the process that linemen go through to tension/sag conductor lines. We look forward to meeting our liaison engineers soon and beginning the prototyping phase!
