Design a vortex tube
The project consists of designing a 3D model, a simulation and a drawing of Ranque-Hilch vortex tube.
This product is supposed to create a cold fraction and a hot fraction from 6-7 bar compressed air, the cold fraction is a temperature drop of 40°C.
The material of the tube is aluminum, we are willing to manufacture it on cnc lathe, so consider fabrication requirements and optimal material use.
Men's Wristwatch
The design submission should include:
Rendered Imagery: showing front, back, top, bottom left and right, and 3/4 perspective views. Rendered views for the front, back, top and bottom can be combined into one or two image files if appropriate. The perspective view must be a separate image.
It is encouraged that the rendered images be as realistic as possible and provide enough lighting to show design details. Environment and lighting style is left to the designer.
Requirements:
1. Men’s wristwatch.
2. It should have an outdoors and sporty look. An ideal buyer would be someone in the armed forces.
3. Illumination around the watch ring and on the hours seconds and minutes hand using tritium tubes.
4. The closest competition brand would be Luminox.
Modern wooden Arabic Incense burner (Mabkhara)
Hello Designers,
Mabkhara (incense burner) is a well know product used in the Arabic region to burn agarwood using hot Charcoal. More information on Mabkhara and how its used please see this video or other similar videos.

Traditionally is was made from wood with copper nails as decoration or in some regions and completely from copper in other regions.
we are looking to modernize the wooden Mabkhara shape but using the same materials. This is a video on how its made (sorry its in Arabic, but the process and the materials is clear)

Important information:
1- charcoal temperature is around 350 - 420 C (depending on charcoal size), so placing charcoal directly on the wood will burn the Mabkhara. There should be a separating material such as Aluminum to isolate the hot charcoal from the wood as to cover the charcoal hole.
2- Hot charcoal needs oxygen to keep burning, so the charcoal needs air flow and can't be hidden.
3- the Mabkhara is held by hand, so the shape should support that.
Thank you and be creative.
Medicine Ball
We are looking for design concepts for a PVC/Rubber medicine ball design. I have included a file showing some of the products on the market. We do not want to copy the designs but want something unique and attractive for a commercial gym application.
We desire the ball have a texture on the surface to aid in gripping the ball when it is thrown.
Color scheme desired is gray and orange but we are open to other ideas if you think it is very attractive.
The ball diameter needs to be 14 inches in diameter.
A logo needs to be on the product and also the weight of the ball in pounds.
