User testing using my final design has proven successful. With the minimum of instructions, Anna was able to use the device correctly. The feedback on the scale and ergonomics of the device were positive. I will use these images and others to produce a storyboard, detailing the way in which the device is used.
Today, I completed my computer aided design modeling. While it has taken a number of days to produce the components, this has been an important process. It has given me the opportunity to consider factors, such as; what I need to modify to make the design function, the overall aesthetic and balance of the piece, potential material choices, the internal systems and how they fit together, wall thicknesses. Having produced CAD models, there are still a few issues I haven’t completely resolved. While I have a good idea of how the pieces can fit together, and be opened and closed, I’m still not sure if they can be manufactured in the way I’ve designed them. One of the ways I’ve thought about ensuring the base and lid remained closed during use is by using well positioned magnets, but this idea may still develop.
I can now use my computer models to produce in-context boards to show how the design will function, along with features boards to explain how the piece could be used. The next stage was to apply materials and textures to the models, to give a more accurate representation of how the piece will look in reality. This gives me a good chance to experiment with different materials and finishes without having to take the leap into production. Often the outcome can be so realistic it is hard to tell whether an image is a photograph of a real piece or a rendered virtual model. On this occasion, I was keen to see how the piece might be made in aluminium. I am keen to avoid unnecessary finishes, such as chroming, as this process can have potential negative implications on the environment. I will continue to use CAD in an iterative manner. Over the next couple of days, I hope to produce a 3D printed model of my design in corn starch, this will give me my best idea of the true scale. It will also allow me to carry out some basic user tests. In a commercial environment, this model would be useful to present to a client to demonstrate my design intentions.
Having produced a design for the inhaler yesterday, I met up with Sean to work on creating some larger scale models which could represent the installation. Our idea at this stage was to develop one shape which would be suitable for both a jewellery piece, and also as a building. We both agreed that the structure was striking and interesting enough to be effective, but neither of us were sure how we might go about making the installation worthwhile. At this stage we weren’t even sure how the building would function, would it be used purely as a presentation piece for educating society about asthma and other medical conditions? Could it be used as a medical facility providing advice and emergency care? Having produced several card mock-ups, we talked about how we might go about decorating the installation. From a technical perspective, I tried to consider the manufacturing of the design, realising that the structure could be made from a steel frame and panels of either fabric or a more rigid material. It might even be flat packed, being transported and erected as a moving display around the country, or even the entire world. Sean decided that he would need more time to research the idea at this stage, and consider what could be applied to either the interior or exterior of the structure to make it effective. Upon returning from research, it became apparent that the direction of the project had moved too far away from where he had envisaged the project might go. We acknowledged that together we had produced some interesting ideas, and some good research. We also agreed that the work we had produced to date was worthy of consideration and could inform us of our next steps, however we agreed at this stage it would be within both of our best interests to continue by working alone for the remaining period, while potentially meeting occasionally to discuss our progress. Sean was keen to explore the more hypnotic and psychological potential of the project, while I wanted to focus more on the structure and products. I think together we had worked very well to produce a good foundation.
This evening I considered the installation again. I think this topic is something I would like to discuss with Theo in my next tutorial. From my perspective, I think I would like to produce not only a product and installation, but a brand, with the goal of changing global perspectives on some of the most common medical conditions. This is something I want to explore in more detail.
This morning, I started by playing with some polymer clay, producing a range of shapes. I was keen to see how textures might be produced by pressing them against things, such as wallpaper, leather straps and smooth surfaces. I was also keen to try and fold the clay, so when it dried it might mimic the plastic wrappings of a chocolate bar. I think my most successful outcomes came with trying to produced the thinnest layers of clay, which I then wrapped around rounded forms.
This afternoon, I undertook an often overlooked part of Product Design at university; reverse engineering. as an asthmatic myself, I have a number of old inhalers, one variety of which is an ‘Accuhaler’, a disc like product which can hold up to two-hundred doses of medication. From the exterior plastic casing, it is not obvious how the internal system works. Upon attempting to open the device, it became apparent that it was designed to be difficult to open and disposable. When I did manage to get in, I was greeted with a vast number of small white plastic components. The device functioned without it’s complete outer casing, which showed how a reel of plastic and foil were separated to release a pre-crushed powder by the tension of cogs. When using the lever, the numbered wheel turned to show one less dose remaining in the device. While there is no question that the device functions well, it might be considered over-engineered for a product which is designed to separates a foil ribbon from a plastic ribbon, before allowing the user to inhale the released powder.
Later, I considered the way that the mechanism functioned to put tension on the ribbons. Were there any other ways this tension could be produced which might simplify this system? I stripped the design to the bare essentials, a reel with two separable ribbons which released the medicine upon separating, running on a central shaft. The idea came to me at that stage, that if the ribbons were exposed to the exterior of the design, you could apply the necessary tension, on each, by hand to release the medicine. If the ribbons were numbered with the number of doses remaining, then this would remove the requirement for a numbered wheel altogether. This potential design would also owe itself to have easily accessible internals, a design idea I was keen to explore. I believe that if the casing is made desirable and precious, there would be no need to throw it away, only to replace the reel inside, this in turn would mean less waste too. With further development of card models, I have developed a model which resembles the human heart in some ways, a design I am going to explore further next with computer aided design.
This morning I had my tutorial with Steve Thompson and two fellow students, who study Graphic Design and illustration. During the hour long session:
– We discussed the work of a designer, and how this must be inspired and underpinned by either; 1) a repeating and recognisable style, or; 2) a philosophical belief system. It is this that the client really pays for, and it is this which keeps a designer working during tougher days when ideas are hard to come by.
– We discussed parallel universes and mathematical theories, including quadratic shapes and fractals, and the Klein bottle structure.
– We applied each other’s ideas to our own projects, this included considering the paper folded models I’d produced, to the 3D graphic design idea developed by another student.
– We did a twenty minute exercise where we swapped projects and produced ideas for each other’s projects, I suggested the graphic designer could consider making his 3D graphic into interactive products, such as seats which protrude from the wall, or integrate the real products which they might advertise into the graphics. For the illustrator’s project, I suggested he consider what his work might look like if it were to be ‘spaghettified’ by worm holes. The ideas they came up with for my project included: jewellery, public inhalers, family air looms, phone chargers inhalers, pocket monsters, photons and bosons.
