Seperate pages of important information
Logbook page: This page contains the logbook, how much time everyone spend per week, and the general planning of group 7.
Interview page: This page contains the interviews that have been conducted by group 7, a summary of each interview, as well as some small descriptions of the interviewees to give some background.
Weekly research and activities : This page contains, for every week, a summary and overview of the deliverables of group 7. The contents of the page have been structured in chronological order. <==== For the tutors, this is where the document that was originally on this page resides now. This has been done for us to start making an overview of how the final wiki page will look.
!!IMPORTANT!!
The order and contents of all of these sections is NOT set in stone, if you feel like a section should go somewhere else, have different content, or be outright removed, please do so (with consent of course).
Introduction
What will be written here:
- A quick summary of coral reefs:
- What types or coral reefs there are.
- Why coral reefs are important.
- What is currently done to protect coral reefs, and what is still missing (state of the art). <= most important part as this is what we're trying to solve
Problem statement
After having done the above mentioned research into coral reefs, their importance, how we can defend them, and how they are currently protected, we have come up with a method of supporting the current researchers by creating a new method of data gathering. We have designed a buoy based sensing system that is comprised of a diver, which is able to move up and down through the water, and a buoy, to where this diver is attached. This buoy would be able to carry any type of sensor that a particular researcher may desire, and measure a particular parameter at a self specified depth. The buoy would be able to send this data back to the researcher in real time, removing the need for any human intervention that could disturb the coral reef, such as human divers or boat engines.
Not only does this new design add to the existing methods of data gathering in coral reefs, solving one problem. But it also makes data gathering less manpower hungry. Because of these reasons, we believe that our design is able to solve the aforementioned problems.
USE analysis
As the project is focussed around the notion of USE (user, society, enerprise), it is of great importance to start by connecting to the future users of our product before finalizing the design. We have done this by interviewing marine biologists and researchers who are closely related to the topic of coral reefs. The interview page shows the questions asked, as well as a quick summary of the interviewee and the interview itself.
Users
As mentioned previously, our main users, and subsequently the first party stakeholders, are researchers focussed on coral reefs, marine biologists and scientific divers. They are the foremost people who have the means and desires to stop the deterioration of coral reefs. Therefore, they are the people who will most likely be the ones using our design. Other stakeholders of our design include funders of our design, second party climate researchers, people living close to coral seasides and, in some sense, the government. None of these people will ever use our design. However, they will all benefit from our design being implemented. Funders, and subsequently the government (if they also fund the project), will make a profit of off the deployment of our design. Other climate researchers will benefit from the increase in accurate data. Finally, inhabinats of the seaside coral reafs will be able to keep their businesses alive, be they fishing or tourism.
Society
Enterprise
The design of the buoy
Design process
Describe how, for each part of the design, how the designs changed over time, and why these changes where made.
Anchor
describe the transition from anchor to reef hook to multiple reef hooks.
Cables
from chains to cable.
Winch
State why this has basically not changed throughout the whole project + maybe say why only 1 winch was chosen.
Diver
Shape of the diver and what materials where initially planned, but where later changed to X.
Base
Shape, dimensions and weight changes that may have happend.
Final design choice
Show the final design of the bouy and state what could be further improved on the design.
Mechanics of the diver movement
Describe in detail (more detailed than we have done in the design choises) how to diver will actually be able to move up and down through the water. Furthermore, talk about the limitations that the diver will have due to the chosen design (these limitations could also be a seperate section for talking about the overall limitations).
Simulations
CAD stress test
Show CAD simulations, state why they are important to the design, and explain all images correctly.
Unity physics simulation
Talk about the physics simulation (showing may be difficult), explain the limitations set on the simulation, and describe what we wanted to get out of this simulation.
