twelve:twelve wall clock
Introduction twelve:twelve, is a wall clock designed for those who suffer from seasonal affective disorder. The main purpose of this product is to emphasis the time using light to extenuate the time. The light is defused through the corian face, which have been cut on the rear face. The clock uses one hand, which tells the time in increments of 15 minutes, giving an approximate time, as the clock is designed to be placed in an environment where the individual would be relaxed and by not having an accurate representation of the time, hopefully this incentives this. This booklet, gives an insight into how it could be made if it was to go into production. Looking at the twelve:twelve from not only a designing and manufacturing perspective, but also from a financial stand, calculating rough costings of how much it could be sold for, based upon materials, labour and shipping & logistics of the item. This document also demonstrates a typical buyer of the product.

Justifying the RRP price, because of the different parts of materials that go into it. However, the price might have to be dropped to ÂŁ200 for a more realistic pricing point. For this, it might be best to drop the materials costs, by making the product out of engineered boards which have been covered in paper foils or veneers. But also the processing costs slumping the glass and using tooling such as the CNC machine. Understanding the costings, but also understanding the type of processes and development that would need to go into the product in order to get the price down would have to be the next stages in getting the costings down. â&#x20AC;Š

Batch Production The current design hasnâ&#x20AC;&#x2122;t been designed for production, as the processes that has been used isnâ&#x20AC;&#x2122;t manufacture friendly. As there were some features which had a lot of hand finishing. In order to change this, the overall construction would have to be slightly tweaked to accommodate this. Ideally the clock would be made in batches of 55, as this is a rough number of the clock faces that can be out of a 4ft x 8ft sheet of Corian. Some elements can tweaked to reduce the cost of production, the main component which would be quite labour intensive would be the slumping of the glass. As this sort of thing would have to be made by someone who is a skilled glass manufacturing. However, once the initial capital has gone into the research/experimentation has gone into the set-up, to ensure each one comes out correct every time. Then it could be a task for someone to set up the machine correctly but also check the quality of each piece of glass that comes out. On the next page, shows a suggestion of how the clock can be made for batch production, the clock will be assembled from the rear, this means that the clock can be disassembled if needed. But also the clock can get away with being made out of not only Solid Ash, but also MDF to bring the price down. Note: The drawing shows the basic construction, with any hardware or electrical components.

Target Audience The Target audience for my clock, would be predominantly those that have Seasonal Affective Disorder (SAD), as that is the main purpose behind it, and who it was originally designed for. However, it is also targeted at those that would be looking for a wall clock that is slightly different, and be a conversation starter when walking into a room. The typical location for this clock, would be a place around the house, where the user would see the space as personal. As some people have mentioned to be that it looks like a wrist watch with a very personal feel to it.
