Trinity's Reverse-Engineering Project by Threatt https://padlet.com/trinthreatt03/9dbxav8hv76bf2n9 Welcome! This padlet is a high school engineering project. en-us 2020-11-17 16:26:45 UTC 2025-10-10 22:15:57 UTC hello@padlet.com https://padlet-uploads.storage.googleapis.com/143034487/c20659dd488b4eb1e68c24db93a87b7e/Icon.jfif Day 1- 11/17/20 trinthreatt03 https://padlet.com/trinthreatt03/9dbxav8hv76bf2n9/wish/932583832 Today I began my reverse-engineering project. The goal was to identify an object that I can take apart and design on CAD software. The criteria was as follows:

  • interact with daily
  • more than 1 part
  • appropriate level of challenge
  • ability to take the object apart

The object I selected is my metallic water bottle. My back-up plan is my my computer monitor.

One problem that I have with this water bottle is that it's easy to drop. This bottle also dents easily so innovating something to get a frim grasp on the bottle would be necessary. My innovation is adding grips to a specific section of the bottle. Something that resembles a rubber sleeve but you don't have the hassle of keeping up with putting it on and taking it off to wash.]]> 2021-01-22 17:16:10 UTC https://padlet.com/trinthreatt03/9dbxav8hv76bf2n9/wish/1114994929 Day 7.2- Innovations trinthreatt03 https://padlet.com/trinthreatt03/9dbxav8hv76bf2n9/wish/1122545287 Innovation 2
Another problem I see with this bottle is that it needs better insulation and it's very hard to clean. One innovation would be to let the bottle come with an attachable cleaning device like what baby bottle have. This would be an attachment to the lid of the bottle that would help cleaning the bottle.]]> 2021-01-25 15:48:29 UTC https://padlet.com/trinthreatt03/9dbxav8hv76bf2n9/wish/1122545287 Day 8 - 1/26/21 trinthreatt03 https://padlet.com/trinthreatt03/9dbxav8hv76bf2n9/wish/1127756140 Tell a friend

Today I was tasked with partnering with a classmate and telling them about my designs and innovations. Afterwards, my partner gives feedback which will be written below. The criteria is as follows:

  • Partner with at least one classmate (or friend or family member). Tell him/her about your reverse-engineering process and ask them what they think of your innovation. Document their feedback to include in your report.
My partner was Evan Stripling  and here is a summary of what he said about my design and innovations:

  • He liked my innovation to make a better grip on my water bottle or add an existing one.
  • In addition, he commented on how he values water bottles with good insulation and how this one seems to have that insulation.
  • Lastly, he liked my innovation in making the bottle easier to clean noting that the bottle did look harder to clean.

That being said the properties of this water bottle would have to be assigned the proper materials for good insulation. For my water bottle the part material assigned was A4 stainless steel and its total weight is 1.909 pounds. For the lid of the bottle the material assigned was hardened stainless steel. This bottle also has properties in color. The original colors were black and silver because I wanted a water bottle that I could easily personalize. However, with my CAD rendition of this bottle I made the main color of the bottle blue so it could truly be seen.]]> 2021-01-28 01:08:45 UTC https://padlet.com/trinthreatt03/9dbxav8hv76bf2n9/wish/1134326892 Day 9- 1/28/21 - Conclusion trinthreatt03 https://padlet.com/trinthreatt03/9dbxav8hv76bf2n9/wish/1139016092 Design Process
To start the CAD model of the bottle, I sketched the bottom of the water bottle that I would extrude and add onto. Next, I extruded the bottom of the cup that the bottle’s weight settles on, so it was important that the dimensions were labeled correctly. After extruding I created a new sketch that would come to be the spout of the water bottle, perfectly centered I focused on making the actual slants and finer details of the bottle. Finally, I did the smallest details on the bottom on the bottle and then moved onto the lid. The lid of the bottle started out as a circular sketch that was extruded with another circle on top of that extruded and filleted. The hardest part of this project would be the slanting near the top of the bottle as shown in the picture below. I really enjoyed this experience of reverse engineering this bottle. This project taught me to document all of my ideas on paper and how to experiment wholly with different factors of CAD.
