Another CrowdCAD challenge! Luxury yacht builder Saare Yachts needs help with designing their deck vent. Come up with the best solution and bag a cool $2000 for your effort.
The challenge is to design and engineer a deck vent solution that works both when the sailboat is in the middle of the sea, and also when docked in the harbor. Deck vent lets fresh air into the cabin of the yacht to keep the humidity levels inside and outside as close to equal as possible.
The ventilator must be easily adjustable to let in as much or as little air as the user wishes, it needs to operate smoothly (seawater and dirt are a constant companion), have a visual indication that shows how open or closed the vent currently is, and be low maintenance.
The vents currently used have a couple of problems – a threaded system is not best suited for the sea as dirt and salty sea water can enter the thread, making the adjustment of the vent difficult or impossible.
Secondly, the threaded system is not the most user-friendly option as it can take more than 10 turns of the knob to fully close the vent. As said earlier, there’s also no indicator telling whether the vent is open or closed.
In addition to that, Saare Yachts would like to see alternative materials used instead of stainless. This is not a hard requirement though, whatever material you use should withstand salty sea water and has to be easy to clean.
Below is an image of a ventilator by Vetus which is used today.
New closing mechanism – something other than the threaded system used today
Weatherproof – must last on an open water yacht
No direct access to the cabin through the ventilator
Vent must withstand human weight once installed (if somebody accidentally steps on it)
Air and water proof once fully closed
When open, rain and random splashes of water should not get through the vent into the cabin
Simple manufacturable design
Ease of installation
Maximum airflow possible
Dimensions – use the Vetus vent (see below) as a soft reference
Design – keep it elegant, we’re dealing with a classical sailing yacht here
Soft requirement – you are free to pick your material
Winning design will be chosen based on the functionality and the opening/closing mechanism, and all other requirements outlined above
The competition is open to everyone.
Team entries are welcome. In case of team win, prize money will be transferred to team leader who is solely responsible for splitting it among team members.
You can submit several designs.
Only models uploaded to GrabCAD library will participate in the competition.
Tag your model with “saareyachts” to make it easier to find.
You may upload a private model but you need to share access to firstname.lastname@example.org
Privately uploaded models will be made public after the competition deadline.
Models can be done in any CAD software as long as a STEP or IGES files are also uploaded.
Competition starts: 3rd of August, 2011
Competition ends: 14th of August, 2011
Competition winner will be announced in GrabCAD’s blog.
The best design will be picked by a joint jury of Saare Yachts and GrabCAD
