Evaluation

         Our artefact does meet the design brief and the evaluation criteria. Only that in the testing of our design we got a score of 4/10. And while the testing is going on we’ve observed the flaws and correct aspects on our artefact. One thing we have observed is that it depends on one thing for it to sort accurately. And that is the rate of pouring the balls into the sorter. If it is poured all at once, one marble is mixed with the pingpong balls. Though there are circumstances that even though put fast it sorts efficiently. We found out that the solution to our problem is by pouring the balls slowly or one by one. Because if the rate of a marble/ marbles is fast, it will not go under the track we made where they should go to separate from the pingpong balls.Also while testing, our friends, Rolly and Matthew told us that maybe if we made the holes or spaces of our track smaller/thinner, it would’ve sorted better.

           For us the best feature of the sorter is the sorting mechanism /the tracks. It is the cream of the crop. It’s the sorter in the first place, it wouldn’t be a ball sorter without it. And also because it’s done neatly and unexpectedly sorts the balls smoothly.

            The least satisfactory feature will be the entrance of the balls located on the roof. It is too small and pouring will be quite difficult. We actually planned to have a some type of vent instead of just a hole but our time was cut short. So that is the feature that could’ve been much improved. Also the tubes after the track, it was just done quickly so we think it could’ve been done more nicely.

             But overall, the sorter is quite satisfying. Not purely satisfying because it kind of disappoints us that it still depends on a thing for it to sort accurately. But besides that we are proud of our design. It is neat, clean and even has wheels which makes it easy to transfer and is also lightweight so it’s really portable. So JilaNd Incorporated is happy with the finished product.
