Group Name: Kangas

Gadget: Acoustic Speaker

About our Gadget: The phone will sit directly in the centre of the speaker with approximately 3cm on either side. The phone will only sit slightly in its holder (~10mm deep), allowing easy access to the whole phone and there will be a cut out around the home button. The speaker itself works off of 2 holes that connect to the speakers of the phone through the hollow base structure of the speaker. As an end result, the acoustics of the speaker will amplify the sound from the phone.

Initial Sketch Photo:

The phone sits in a base that has two cup like structures on either end. The speaker will reply on acoustics to amplify the sound.

Initial Clay Model:

Our design is one elongated structure with a hole through the centre base.  A back rest for the phone is there for support.

Draft Product Photo:

Our first printing attempt was quite successful however the support given to the phone needs to be greater.

Final TinkerCAD Design Photo:

Our final design added support for the phone and the speakers were made more cupped as to increase the amplification.

Design Reflection: The process of making our speaker was very simple and streamlined once getting the blueprint into TinkerCAD. When sketching and making the clay model we struggled to get everything dimensionally correct, but TinkerCAD allowed us to manipulate each dimension individually. This allowed us create our final product after not much work.

Module 4

Step 1: Evaluation

Cube and Sphere: This design was successful as we were able to print both a cube and sphere in the same design where the end result was two disconnected objects. The base that the 3D printed was easy to disconnect and did not effect either of the objects. By printing two objects in a single design, it saves time despite the fact that you have to disconnect the objects at the end of the printing process.

Alphabet: This test was unsuccessful as we were trying to get the letters to touch each other. The 3D printer was able to print in a higher resolution than TinkerCAD allows you to go in. We placed the letters .1mm apart which is the smallest increment that TinkerCAD allows and the 3D printer was still able to print the letters with a space in between. From this design we have discovered that the 3D printer is very exact and will print objects .1mm apart successfully.

Freestanding rectangles on base: This test was also unsuccessful. We wanted to create a freestanding rectangle that under its own weight would be weak and structurally unstable. The material and format in which the 3D printer used created a structure that even the thinest rectangle not only was able to stand under its own weight but also could support human interference in the shape of trying to bend it.

(As our group's freestanding rectangles were not printed, this is a photo of another group's printed freestanding rectangles.)

Step 2: Evaluation Rubric

Criteria	Does not meet (0 points)	Meets (1 point)	Exceeds (2 points)
Ease of print	Design is not streamlined causing a lot of extra material to be used or extra time to print.	Design uses some excess material that could be done without.	Design is streamline and prints perfectly to the point that no excess is material is used
Stability	Can't withstand its own weight.	While it can withstand its own weight, any force causes structure to become unstable.	Withstand its own weight, even when force is applied on the object.
Dimension	Too large/small for proper function	Dimension is not perfect but gadget can work somewhat	Perfect dimensions allowing gadget to work efficiently
Functionality	End result does not perform intended function	End result does not perform function perfectly or is able to perform function with the help of outside factors.	End result does perform intended function perfectly.

Module 3

STEP 1: TinkerCAD explorations

We measured in mm as it meant we wouldn't be working in numbers less than 1. The original cube design on TinkerCAD was 12.7mm cubed and the sphere had a diameter of 6.35mm. The cube given to us was 25.4mm cubed. We therefore doubled the length of all the sides and doubled the dimensions of the sphere to keep it proportional to the change of the cube.

How was it created?

When we ungrouped the design we found that it was made by a solid cubed that had been hollowed out by 3 rectangular 'holes' that go from one side of the cube to the other. The sphere has been made by using the basic shapes and then simply dragging it into the centre of the cube.

Related Gadget- Cannon Speaker

                             

 

https://www.tinkercad.com/things/3aQrEGsexIF-speaker

This design was started by taking a cylinder and putting it on a rectangular base. Then the cylinder was hollowed out to project the sound. A groove is added onto the cylinder to hold the phone. Then it was angled to project the sound upward and outwards. Then shapes are added to add to make it look more like a cannon.  

STEP 2: Limitations

Cube and sphere

We chose to test this design because it allows us to see whether we can print two free moving separate objects in the same print by connecting them with a thin connection piece that is broken off after the object is printed. Thus potentially allowing two objects to be printed in the same print. If this is something that is able to be done, the time that it takes to print 2 objects can be significantly reduced by printing them in a single design.

Alphabet

We chose to use this design to see how close together we can print two objects without them fusing together or the needle not being able to print anymore. Some designs that aim to leave space between 2 objects may work in theory with TinkerCAD, but limitations of the printing process could mean the printed design is actually connected. Knowing the distance between two objects in which the 3D printer can still function and leave space between the two objects is very important for the design process.

Freestanding rectangles on base

We chose this design to test how thin a 3D printer could print while still being able to hold itself up. Contrary to the alphabet test, knowing how thin the printer can print an object is also important. Not only does this show how accurate it can be with details, knowing the thinnest possible line helps us understand how strong/weak the overall design can be. Thus resulting in being able to print something that will not snap under its own weight.

STEP 4: TinkerCAD: Gadget Design

STEP 5: Show and Tell

Bottle Opener- This object functions as it is supposed to and has a very different design to that of a traditional opener.

Shin Guard- This object didn't seem to have the right dimensions to fit a shin. We are unsure at this point if it is still in the design phase however we think that new measurements will be needed to make it fit right.

Phone charger cable- This object looks like it would be very useful. If the dimensions are correct, we can see this being a success in giving the iPhone cord structural support.

C-clamp- This design is made of 3 seperate objects that will need to be put together. The idea is very interesting as the opening is different to that of a traditional c-clamp. If it is successful we believe this will be a very effective way of storing keys.

TinkerCAD- 6 basic skills

Skill 1- Learning the moves

This tutorial taught us how to move the shapes around. It was very easy as all you had to do was click and drag with your mouse.

Skill 2 - Camera Controls

This tutorial taught us how to change the view point of our model and how to zoom in/out. You can change the view point by either clicking control and moving your mouse around or by clicking on different sides of the cube in the top left hand corner of the screen. Zooming is accomplished by either the zoom buttons of the left side of the screen or by how you would normally zoom on your computer track pad. 

Skill 3 - creating Holes

This tutorial taught us how to remove material from an object. Firstly, you can choose what shape you would like your hole to take from the right hand panel of shapes. You then need to drag the shape on to where you would like your hole to be and click on 'Hole' in the inspector window. From there, you need to group the objects by selecting both of them and clicking on 'Group' at the top of the window. You will now have a hole in your object!

Skill 4 - Scale, copy and paste

In this tutorial we learned how to change the scale of the shape and how to copy and past objects. Copying and pasting is done how you would typically copy and paste (command-c for copy and command-v for paste). To change the scale of an object you simply click on the object and move the white dots to the dimensions you desire.

Skill 5- Creating Custom designs

This tutorial taught us how to bring multiple objects together. To make it easier to position the objects correctly, you can change the snap grid from 1mm to 0.25mm by clicking on this option on the bottom right of the screen. We also used our previously learnt skills of resizing and grouping to complete the key chain and make it a single object.

Skill 6- The Workplane

This tutorial taught us how to use the work plane. To access the workplane you simply click on the workplane on the right side of the screen and drag it to where you want on the grid. To reset the workplane, simply drag it to a blank spot off the grid.

Gadget Design Phase 2

Redesign of clay model

Note: Because of the structural deficiencies of clay, we had to add a square prop to keep the speakers circular. This square prop will not be included in the final product.

We have changed our speaker design slightly, making it less of a box with 2 cup like structures on the end to one elongated shape with holes on the side. Because of this change, if the speaker is ever mass produced, it would not cost as much as less material is being used. It also looks a lot more streamline and modern. We also added a back rest for the phone so it would be able to support its own weight.

Scale Model of Design

                                     

The phone will sit directly in the centre of the speaker with approximately 3cm on either side.  The phone will only sit slightly in its holder (~10mm deep), allowing easy access to the whole phone and there will be a cut out around the home button. The speaker itself works off of 2 holes that connect to the speakers of the phone through the hollow base structure of the speaker. As an end result, the acoustics of the speaker will amplify the sound from the phone.

The hole in the base of the speaker will have to be made quite large to avoid it becoming clogged in the printing process.
