What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About this project

In December of last year, I started making prototypes of an offstring yoyo I would eventually be producing.  After coming up with a rounded organic shape with a flat hub, we found that although the width was adequate, the shape made the yoyo hard to catch, and also would not bounce.  We attemped a second prototype of this shape, hoping that a slightly wider profile would fix the issue.  We then approached world champions, regional champions, and top players to help create something that would be fun to play, and easy to use.

I started working on my 4a, and found that a rounded profile that led into a straight rim area worked the best for offstring yoyos.  We ended up creating a yoyo that was an o-ring press fit assembly.  Although this yoyo was easy to use, the axle system was not very secure.  I also attempted an assembly, where the yoyo would be held into place by two discs pressing against each other, but that also was not secure.  We decided that it was necessary to make the yoyo with a hex assembly, but that took away from the weight of the yoyo. 

After Renta Motoyama joined the team, we conclusively decided that the yoyo was not wide enough.  He gave me the dimension of around 65mm to toy around with, and I made two designs, of a smaller diameter, to keep the weight from approaching 80 grams.  One was a design that had two straight segments in the profile, with a built in weight ring, and the other was an organic shape.  We decided that these both weren't enough, so we combined the two, creating a yoyo that was composed of two straight segments, but rounded at the intersecting segments.

The result was this yoyo that we have before you today.  

Risks and challenges

This yoyo was the hardest yoyo related project I have ever done. Throwing away thousands of dollars to create prototypes, and familiarizing myself with a playstyle I am not proficient in, it was a very long journey for me to be able to present this yoyo. We would barely break even with this project, but I feel that it is worth it.
