The third part of this task was the development. After having had a concise idea of what I would do, I needed to develop the idea further answer some of the key problems in the overall design of my product.

The Necklace problem

The first problem which I addressed was how the necklace would be attached to the lightbulb. I made multiple sketches and models displaying the potential way the lightbulb could be held.

The first page highlights key ways to attach a string whilst the second page highlights ways to attach a chain instead.

The first one designed highlights how the string would be attached using a knot, the second one using hot glue, the third using a drill to make a hole in the lightbulb to attach the string and the final option is to use a which the string would attach to using a knot

I was not satisfied with any of the ideas as I thought the aesthetics of the strings were a bit off, I then decided to try those methods using a chain instead as it would look more professional.

For the chain, I used the same method of sketching and modelling to create something which was satisfactory to me. The different ways I came up with to attach the chain were, to make a knot, to hot glue it, to make a coil which the chain would just slot in, to create hooks on the side which would attach to the chain and the last idea I had was to simply drill a hole.

I decided to go with the chain attached to a coil as my final concept as it looked aesthetically pleasing and looks professional

Other Problems

Other problems which I had no answer for was how a hole was going to be made in the lightbulb. I made one by hand in under an hour which I thought was a good time. I theorised that I could use a drill but when I asked the University workshop, they told me the lightbulb would be likely to shatter due to the vibrations created by the drill. I thus concluded that the best way to make a hole in the lightbulb would be to manually do it using a multitude of pliers and other manual tools.

Another problem which I encountered was how the lightbulb would be held when not in use. This was a key problem because the bulb was not stable enough to hold on it’s on, this meant that dirt, water or even the plant could fall unto the surface the bulb is left one. This also meant that bulb would be likely to roll off a table and could shatter upon impact with whichever surface it falls on. I found a solution for this, the solution was to create a stand on which the bulb would be held on when not in use. I concluded that an easy yet aesthetically pleasing way to do so is to make a hole of the diameter of the lightbulb in a cuboid to create a receptacle which would hold the necklace.

The models

The models were made throughout the development, but to keep order in my sketchbook they have their own sets of pages. I made multiple models each varying for each other which help me find a final product.

There were four types of models, The initial models, the development models, the developed models and the final model.

These are the models, each model has an explanation beside it stating its purpose and what it taught me.

This concludes the development of the necklace.
