I wasn't actually based in Aberdeen when I did this project. The Sediment Trap Re-Design project that I completed was proposed by one of my lecturers at Glasgow University and I took on the project at the beginning of the last accademic year, as part of my compulsory final year project. (The course I am studying is Product Design Engineering, it is a joint course at both the University of Glasgow and Glasgow School of Art.)
At the beginning of project I had to find out more about Sediment Traps: who uses them? why? and how? Along my travels I came across Marine Scotland Science and John Dunn who helped me greatly with initial research and insights into Marine Scotland.
As I moved on with the project, concept generation was vital and the staff at Marine Scotland Science were excellent at coming up with ideas and giving me key advice on what would work and what wouldn't work. The key design criteria for my trap was to design a portable solution, which could be carried on foot to the desired location.
The final concept I landed on was for the trap to be able to split into three parts to spread the load of the trap. The 2 main parts I concentrated on were the funnel and the carousel. The funnel is made from a patent bi-stable reeled composite called RolaTube(TM) which is lightweight, high strength and can be rolled into a thin tube for transporting. When unrolled, the material snaps into its funnel shape eliminating the need for attachments. The carousel uses a clock spring which would be pre-loaded by the user to give tension in the spring. the movement is resisted by a solenoid which is fired on a monthly basis to release the carousel and move the bottle to the next one under the funnel.
