Keep It Simple light project is an organic independent light. When talking about organic forms, the common favorite will be the water droplet design. This project is about reusing the water droplet aesthetic elements to create an independent light. The challenge of this project is to keep that form without associating it with the water droplet design.

The follows pages will run through the prototyping process and also the final outcome of the light.

The mood board is all about the organic design.

It portrays that most people relate organic design back to water droplet design. People love organic design because it is simple and elegant. The aesthetic element of the water droplet design appears suitable for every environment.

To given more clearly comparing of the design been selected from the sketches. I created them within the same body out CAD, and review the effect from the rendered. After the concept presentation, I decided to picked the vision-iv for my further development.

Mark 1 When experimenting with my concept, I created the Mark 1 vision with flat laser cut patterns and folded it to shape. The method works for other application, but it wasn’t achieving what I had envisioned for my initial concept. Hence, I had to find another more suitable method.

Mark 11 Right after Mark 1, I decided the next vision (Mark 11) out of CNC machine. The result is very effective. I believe it was the right manufacturing process for my light production. It uses Top-Back milling process with the 3-axis CNC machine. First, the machine shells the interior surface. Then it turns it around to mill the exterior surface. This process was not easy because the alignment process was hard. After more than 10 hours in front of the CNC machine, I finally have 2 completed components that can be used to assemble as my final lighting design. However, when assembling the light, it did not align perfectly to join up as one form.

These issues can be resolved with 4-axis CNC machine because a 4-axis CNC machine has a spring wheel option that allows it to create the form in one go. About the diffuse of my light. It’s originally propose to make out of injection acrylics or blow glass. Unfortunately, the cost efficiently of my prototyping badgers. I decided using vacuum forming out of VIVA plastics to reducing the cost of my diffuse. Due with many times of experimenting vacuum forms with different materials. I finally get my components done it’s nicely. But I founded it’s very had to get an accurated cut with my form. But It’s still work alright in my prototype. For the final companent of this product was completed out of lave machine, and trim the side by refer from the tange of the body, to created it’s look alike continuely crave.

Construction and Assembly Regarding the construction of this product it has went through a long journey. It was decided that the first construction was to be attached to the components, This method is alright for a tough diffuse, but it was hard for mass production and assemble. Since then, I adapted the plastic diffuse method to make the light. Then, I used an internal- snap fit idea to assemble the components together. First I thought it was a good idea but I realized that the down side of doing that is that the light bulb will overheat. Heat will make the plastics diffuse become weak and it might even break apart. After trying a couples of ideas, I finally decided on the final construction. It will be made out of metal sheet folding which can be easily assembled, long lasting and also balances the product.
