Design //

I spent a lot of time within the first 4 weeks of the execution phase designing lots of different iterations of my product, here i have documented my favourites, and thedevelopment of my final concept.

 

Iterations /

I designed several different forms for the product, they were all based around the one size of screen, which through my research and development discovered that this would best be the size of a sheet of A4 paper. Here are a few of my designs.

This is an early concept that i am not very fond of. I think it is too square and does not compliment the flow of the interface. These are the three materials that i want to work with in my product, aluminium, plastic or wood (probably mahogany or oak). I find these materials easy to work with, and all give a good finish.

 

 

 

Here is a development of my first concept. The intial sketch is the simple shape i first designed which i still love. It has a brushed aluminium shell and dark wooden side panels. The second has been developed to just have a smoother shape and looks a little more modern, i really like this aswell, more than the original concept although it will be more difficult to manufacture. The third concept still has a similar shape but the top and bottom surfaces are now parallel mounted on a hinge to make the angle adjustable to fit the comfort of the DJ. The hinge would be able to sit between 15° and -15°. Through my research (experience prototype) with my users i realised that there was not much point in having this feature because we found the product had its best functionality between 10° and flat. If i am to use one of these concepts i will develop the second iteration further.

 

 

Here is a 3D model of the second iteration from above. I made this to get a better i idea of what it would look like. If i am to take this iteration forward i would make it a little thinner so it would not be so tall.

 

 

 

This is another of my designs that i liked. The shell is made completely of plastic. It does not curve under under the screen again which i do not like as much, but it does demonstrate the flow of the music which i think is very important in the form of this product. I like the black shell alot, it gives the product a stealthier feel to it and fits in more to the style of similar products on the market. The finish of the black shell will be best with a matte finish. I will look further into this, also as a finish on aluminium.

 

 

 

I modeled this design, also to get a better understanding of the overall shape. Here it has the matte black finish with white plastic side panels flush the main shell. I do like this but i still prefer the front and back to roll under the screen, i much prefer the shape.

 

 

 

Here is a set of this design in different colourways, i still like the black version best, it suits the colour of the interface and looks stealthiest which is an import feature of product. I changed the side panels to be grey which makes the overall feel to it a lot smoother and subtle, this is important because i do not want to distract the user from the interface.

 

 

 

This is another iteration of my product, which i really like but i would be very difficult to manufacture and i do not have the ability to make a good mixer (the controls in the middle) to integrate into this all in one product. The unit would have ports to insert SD cards, USB pens, iPod dock and a cd slot to load in the DJ's mp3 tracks. This design would be far lass portable, it would have to be constantly set in the one place.

 

 

 

I was recommended to build the body of the product from concrete, which i have modelled below. I really don't like this idea, it is impractical in every way. It would be very heavy, which would make it difficult to travel with to gigs and would easily smash if it was dropped. It would be very difficult to mass manufacture aswell, although cheap, every single one would have to be made by hand. It would also be very difficult, if not impossible to fix if something went wrong with the elctronics. I will not be carrying this idea forward.

 

 

I have decided to forward with the rolled shell because this is my favourite design and it will be reasonably simple to manufacture, here are some possible materials for it. Red Plastic, Glass, Brushed Aluminium, Steel, Charcoal coloured Alumium and Black Anodized Aluminium. I am going to look further into the black Anodized finish on alumium.

 

 

Physical Requirements //

The product is designed to be stationary when in use so the main property is its weight and stability. With a flat bottom and 4 rubber stands at the corners, the unit will not budge. It also needs to be splash proof in case a drink is spilt. The design of it is safe from splashes, especially if i add a sealant between the screen and the shell.

 

 

Interface Design //

The vital element in my product is the interface in which you interact with. I needed to think what functions were required to operate the device. The TouchTable is based on a TurnTable, so had to mirror their functions, plus more.

Here is a table of the functions of the two products compared;

Colours /

Another important feature of the interface is the colours, this will be relative to where it will be used, ie. a DJ Booth, where it will be dark. Here are four colours that i found best for the product, so i tested them with the DJs with the lights off to see which they found best. We all found that it was best with the waveform being white, and we agreed that the lime green background was most pleasurable to use. I personally like the green interface best because it has a friendly feel to it, and is clearest to understand the waveform.

 

Here is a flash application where you can change the colour of the background with a clour slider (top left), let me know which you prefer...

 

 

Interaction Design //

 

I feel it is the little details that make the interface most enjoyable to use. There also needs to be an element of feedback, to let the user know what they are controlling.

 

The image below demonstrates the interaction feedback when controlling the waveform of the music. When the user's finger touches the wave, a glow grows out from under your finger and there is also a target style image of what point in the song you have a hold of.

 

 

 

This image below demonstrates the feedback from the Pitch Control. When the user moves the slider, there is a live reading of what percentage you are changing the pitch of the song by. This is helpful because it makes this feature very accurate.

 

 

Physical Interactions/

I made a small experience prototype where I hooked up my Phidget that i used earlier in the project to my Max Patch, controlling different functions on the interface. I did this to see if there was a need or purpose for physical interactions in my product. Below is a video of a potentiometer controlling the speed of the song from playing normal speed, all the way down to playing it backwards at normal speed. I decided to not use this because there is no need for any physical interactions other than the touchscreen.

Prototyping //

Prototype 1 /

The first Prototype i made was just a cardboard shell of my intial design. I made this to see how the size would be more than anything else. I used silver card to simulate the look of anodized Aluminium. With this prototype i felt the shape was a little too chunky and i needed to slim it down a little.

 

 

 

Prototype 2 /

I made this prototpe with the same mehod i used in the first, but with this one i took it a lot further. Firstly i slimmed down the size of the shell and i made a bracket from wood to hold the touchscreen in position, tis was so i and my users could get a feel for the proportions of the product. I also added the wooden side panels to the model, like i had planned from my design, but i realised from as soon as i attached the wood i did not like it all, i was time to rethink that aspect of the design...

 

 

I removed the wooden panels and replaced them with white cardboard inserts to give the impression of plastic. I really liked the way the prototype looked after this, the shape was a lot sharper and cleaner looking. I decided to develop this idea further...

 

 

 

Prototype 3 /

This Prototype was made from another of my favourite design solutions, it was to be all plastic, with less of a curve to the model. I again made this from cardboard and painted the shell in the colours that I and my users thought were best, black and white. i did not like the shape of the model but i loved the colour scheme, the black casing looked a lot 'stealthier' and the the lime green interface worked great with the black, unlike the silver where the colours almost drained each other and were too shiny.

 

 

 

Prototype 4 /

I decided to continue with the curved casing, and i am going to make the product from Aluminium. I still could not decide on the colours of the shell so i made a sample piece from a rolled sheet of Aluminium and split it down the middle with the two different finishes i liked. As you can see below, one half is hand-brushed with a white plastic insert, and the other is a matte-black finish with a grey platic insert. I loved both the finishes, and i was hard to decide, but in relevance the the shape and size the product is to be and the lime green screen, the matte-black finish was the favourite, although i will use a lighter grey for the plastic insert...

 

 

 

Final Design /

From my physical and 3D prototyping, i have decided to have the rolled shell with a matte-black finish, with grey plastic inserts and a lime green screen. These have all been my favourite elements of al my different iterations of the product, and i feel they are the elements that work best together and will compliment the interface to the highest level.

 

Here is a short animation i made to show the shape of the product from different angles...

 

 

Detail Design

 

Here are i have placed my company logo (ATTIGO) on 3 possible places, above the screen, on the side panels and wrapped around the back. I like the logo placed on the side panels.


 

 

Manufacturing /

My product will be relatively easy to manufacture. Firstly the aluminium will be cut to size and then rolled in a steel rolling machine to make the form of the shell, this is a simple process, best done by hand. The shell will then be brushed (by hand) to a smooth finish, then coated in a primer then finished with a matte black paint.

The screen will then be placed into the shell, supported by a bracket.

The next step will be to laser cut the side panels out of plastic and then insert them into the sides of the shell, these will be held in place by a rim on the inside of the shell and then glued.
