1. Binder Identi-finder By: Jackson Kotch, Emily Ball, Josh McKinney Honors Engineering Design and Development, Rising Sun High School Problem Statement 77% OF RISING SUN HIGH SCHOOL STUDENTS SAY THAT THEY HAVE TROUBLE IDENTIFYING THEIR THREE RING BINDERS WITHIN THEIR BACKPACK. THIS IS BECAUSE THERE IS NO WAY TO LABEL THE DIFFERENT BINDERS IN A WAY THAT IS VISIBLE WITHIN A BACK PACK. Solution We created a clip that slides onto the binder’s upper edge that will be visible from inside a backpack. The clips will come with adhesive labels that users can write their binder subjects on. Figure 1 Figure 1- A traditional book bag with un-labeled binders. Viability of Problem We found that we had a very good target audience to which we could market this problem. We first decided on a population to conduct research on, which was the students at Rising Sun High School. Then, we created a survey with questions that would tell us if our problem was valid/interesting. We found that 77% of the students were interested in our problem in one way or another. We also found out that students would pay less than $5 for a solution. We predicted that we could inexpensively provide a solution, making a majority of the buyer’s money profitable. Initial Ideas Prototyping Phase We chose to pursue Concept A2 as our prototype. Testing Testing was conducted on all variations of the clip using a force sensor. We pulled on the clip legs and label surface to determine their strength. Results Figure 7- Digital rendering of prototype. Figure 8- Actual picture of prototypes. Analysis We considered our test to be a success! Label surface maxed out the force sensor on our later prototypes. Clip legs would chip, not snap on the later prototypes. Product was still usable. Some deformation would occur on some materials, but they would return to their original shape. Conclusion The best material to produce our product would be Smooth-On Smooth-Cast 325. Acknowledgements Thank you Mr. Burkhardt for helping us throughout the design process and assisting us in the construction of the project. We would also like to thank Jeff Ellis for supplying materials and offering his professional advice.

Label pocket can hold paper labels. -Uses a typical paper clip, and utilizes a label pocket to accommodate paper labels. -Will clip onto the tab that opens the binder clips. Has a label pocket on top the accommodate paper labels. Figure 11 Picture of a clip that has failed on clip leg and label surface.
