  Today was our final project day, we printed the last version of our prototype (image A) with a transparent filament to see the shoelaces better. We tested our prototype and we received feeback from our teachers and some other users.  The prototype worked well for most type of laces, the clip was strong enough to hold them in place. Here is the feedback we received : 

  For different shoelaces users had different experiences :

  - For thin shoelaces the product was not holding well.

  - For thick shoelaces, it was hard to tighten.

  - And for Diego's shoelaces it worked as we wanted. At first we did not give instructions to see if he understood how our product works however, he first tried to put the product horizontally instead of vertically. For the second try, we gave him the instructions and he managed to put his laces alone. 

  The feedback we got from the users was that the laces can come out of their place when tightened so we need to extrude the middle part to prevent it.

  In the end, the teachers asked us if we had four more weeks what would we improve or change in our product. We said that we can make the product more aesthetically pleasing for example adding customisable designs (for example Diego wanted his favorite sport club design on it). We also think of making the lace end holder more stable.

  Today we 3D printed a new prototype with 11 options for the hook (B). Unfortunately, we realized that the hinge is misplaced. So we focused on our old prototype and added the pins by shortening and flattening nails for the hinge using a special hammer (A). After we were satisfied with the hinge, we made our target person try the prototype. We sadly received negative feedback, specifically “not practical”. We will upload the video so that you can be the judge! The video is titled as Log 9 Video.

  Today we finished our new prototype, and we sent it to the teacher so that it can be 3D-printed. The improvement of our clip shown on image B has changed the design of our project (image A)

  Here is the printing process of the new prototype  (images C and D).

  Update: We received the 3D printed prototype (image E and F) and it works quite well. The only issue is the sizing. We need to modify the width of the lace-holder and the grip of the clipping part.

  Today we recieved our 3D improved prototype. The moment we tried to close the snap, it broke (1, 2, 3). This is due to the 3D printing orientation as the teachers explained. We also tried a new alternative for the rod of the hinge. We used a nail and it fit quite well. The only problem is that we need to make it safe by cutting down the sharp side and making it flat.

  Today:

  - We learned that we could modify some parts of our prototype by hand. The teacher used a drill to make the hinge perfectly round. And we sanded the clip to better open and close.

  - We got our second printed prototype. But since it doesn’t have a clip, we couldn’t test it.

  - The teachers gave us tips on how to improve the clip and making it adjustable for different shoelace sizes. We learned more about the geometry that is used for clips. We checked a project from the previous year to get inspiration. (uploaded below)

  - The teachers suggested us to use a slightly different version of a hinge so that it doesn’t move while trying to open and close the clip.

  Today we received our first 3D printed prototype! We assembled it and immediately noticed some flaws. The hinge is not printed as a perfect circle. This is because of the way the 3D printer prints. So, when we tried to attach the hinge with the ink container of the pen, we couldn’t insert the container into the hole. And even when we hardly did, the hinge could not move. There is also another reason for no movement: the clip. The clip works when we close it, but we cannot open it back. We figured that the reason for this was because the material is too hard and not flexible. This isn’t that bad since we also need to make our prototype durable.

  So, the focus for today is to make an improved version of our prototype to 3D print it along with the second prototype. For the improved version of our first 3D printed prototype, we concluded that we need to make the diameter of the hole around 1.5 mm bigger (new diameter: 4.5 mm).  We also agreed that the length of the base is too long and decided to make it shorter for the improved version.

  Update: We tried the prototype even though the hinge part doesn’t work. We saw that the shoelace wasn’t holding well. It slid easily from the prototype. This means that the opening is a bit too large for the shoelaces. 

  The photos of the prototype are in the "Prototype Photos Log 5" file!

  Today we are working on the prototypes and thinking of getting them ready for next week. This is because next week our user Diego will come to the lab to test our prototypes. We have been told to make more than one prototype to pick the best working one. 

  Last week at the end of the course even though we had a prototype ready, our teachers said that 3D printing a small hinge won’t be durable enough and will easily break after a few uses. They have recommended us to use an already existing object for the hinge. We found today that the best working object seems to be the ink containers inside pens. The size is appropriate for our project which made it the most suitable option.

   Update: We showed our prototypes to the teachers and there was a slight problem with the sizing (1a, 2a, 3a). We chose a 0.5mm thickness which is not durable enough and hard to print with the 3D printer. To guide us, the teacher gave us an object that contains all the thickness. This object (A, B) gave us a better understanding of the sizes we should use for our prototypes. The fixed version of our prototype has now a 2mm thickness(1b, 2b, 3b).

  Update: We showed the fixed version of our second prototype but there was another slight problem with the clip that we wanted to do(1c, 2c, 3c, 4c). It turns out that it is more complicated than we thought. For the solution, the teacher sent us documents to guide us and visualize the geometry we need to use for the clip. We changed the shape of the clip with a better geometry(1d, 2d, 3d).

  Today, we worked on our prototype on FUSION 360 and we think that we have our first printable prototype.

  We know that this prototype 1 isn't going to be our final project but we still hope that it still can be used.

  We decided to make the clipper ( prototype ) in 3 pieces, two for the main parts (up and down) and the last part is to link the piece together.

  Then we'll have to add 2 more pieces inside the clipper because that's what is going to hold the laces.

  Here's some examples of material and how it's going to help us holding the laces in place :

  - if we use rubber, the 2 pieces of rubber will get squished against each other and with the laces in between it won't move.

  - if we use plastic again, then we'll make some pics in a certain direction to allow the laces to be tightened without allowing them to get loosened. (but this idea doesn't seem practical because both laces aren't going in the same direction.

  Here's the dimension of our printable prototype 1 :

  - length : 2 x 3 cm

  - depth/height : 1 cm

  - hinge : ~ 3cm

  Here's how our prototype 1 is :

  For the next session we'll try to 3D print it !

  Today we focused more on our prototype and the feedback we got in the previous session. And thought of ways to improve it. 

  Summary of the first try of the prototype : 

  At first Diego didn’t know how to use it without explanation 

  Then we explained to him how to use it and he had trouble putting the laces in it as said in LOG 1.

  So we should put some small intersections for the laces so that the laces do not move.  

  We noticed at first that he had trouble pull the laces

  But at the end we saw that he could do it 

  More details on our prototype (for now) : 

  Made of two pieces in cardboard : 

  In rectangle one large and one skinny to imitate the clip. 

  Some rubber band

  Creation For Diego’s Laces 

  For who?:  For Diego 

   Problem: He can’t tie his shoes. 

   Solution: The solution can be to create an object to help him tie his shoes by replacing the tying and untying part. 

   Imrovement: The prototype needs to hold a bit the laces so that they don’t go everywhere and make it even more difficult for Diego. 
  

  Feedback we received : 

  Diego seemed to have trouble keeping the laces in the same place when putting the prototype on. So, it would be nice to add some small insertions for the laces. Then it would be nice to have a better clip to open and close the prototype.
