Ripstop Nylon Prototyping

My latest full-scale prototype has a few new additions including 2 doors, an elevated foot, and the ability to be pitched with two aluminum poles. So far the Ripstop has been doing a great job but I plan to do some wet weather testing this weekend about 60 miles outside of the city so I can look for failure points, design problems, and sizing adjustments.

Stay tuned for more photos of the tent in use as well as my first full-scale attempts at attaching multiple tents!

SolidWorks Pattern Design

As I continue to prototype my tent design, precise pattern cutting and sewing has become increasingly more important. To show you a bit of that process here are some SolidWorks drawings of the current pattern including doors and an elevated 'foot' at the bottom of the tent.







Testing Ripstop Nylon

After deciding that Tyvek is not quite durable enough to be used as a tent fabric, I have begun prototyping in Ripstop Nylon. Nylon is the standard material for rain-flys and tent-bodies, so it seemed like a good place to start. This prototype has an updated pattern to allow for more headroom inside the tent. Although this model seems to be about 6 inches short for someone my height, once doors are added it may be the perfect length.

Tyvek Models

Here are some photos of 1/16th scale models I've been making out of tyvek. This series was focused on patterning to allow for a "box" at the bottom of the shelter to give the user room for boots, packs, etc. Stay tuned for more full-scale prototypes made of rip-stop nylon. I believe the model in the final photo does the best job of efficiently creating space at the end of the tent.

Testing Tyvek

Over the past week I've been making some simple full-scale tent prototypes made of Tyvek. Tyvek is an inexpensive fabric-like material made of spun olefin fibre, it is somewhat durable, but very light-weight and water-resistant. Tyvek is manufactured by Dupont and is well-known for it's use as a cover for construction projects.

The main purpose of theses shelters was to test the strengths and weaknesses of my materials as well as my design. I can now work from my current models to define problems and improve my design. These shelters can be supported with a trekking pole, or strung to a tree.

Quick Sketches

Here are some of my early 3d sketches for the Simple Shelter project. I was just creasing, cutting, and bending paper and plastic bags to shape in order to begin thinking about the forms and possible functions of my tent design.











Shelter Ideation

Here are a selection of the early tent concepts I've been working on. These sketches were focused on the modular and pole-free aspects of the design problem.
