So, I have finished sketching'up my pack idea and I am thinking I may have found someone who can help me put this thing together. But, its my first pack design and so I am not so arrogant to presume I know what I am doing. With that, I am posting some images of what the design looks like, and am interested in hearing peoples opinions.
The intent is to hold, rather snuggly and very stable, a number of stuff sacks and gear in various sized bags into a carry-able mass. Its not as minimalistic as some designs I have seen here though. I am trying to find a comfortable median that suits my wants and needs.
Keep in mind, I love having a top compartment. It keeps my life much more organized on the trail and makes packing and camp life much more enjoyable for me.
It consists of a bottom compartment that compresses all the campsite gear, a mid compartment that is fairly minimal, side pockets that are more tie-sleeves of mesh or cuben fiber. Since the side walls of the pack are minimal, these sleeves/pockets don't create any wall redundancy. Finally, the top compartment. This avoids redundancy in the sense that the top of main compartment is open. Further, heavy materials are used on areas of high abrasion and duress while ultra-thin materials where strength is not needed (eg underside of the top compartment). I am thinking all compression straps should be cords, attaching through tie-loops or o-rings.
The harness isn't shown as I am just not that skilled yet. My z-lite thermarest is cut down in size and folds into a compartment for the back-pad, and 4 tent poles, used in the tent form an externally accessible hard-frame. Maybe the harness will be attached through the hard-frame to distribute weight away from fatigue-able seams.
Well, that's the short explanation. One choice fellow go a longer explanation ;)

I think I get the concept. It is a little hard for an old guy like me to follow the drawings, but is the top compartment the trapezoidal shaped part? Will it be able to scissor up and down to accomodate diff stuff sacks?
Cant wait to see the final product.
keep thinking outside the box.

You know, I hadn't thought of that. But, when you look at the design as it is…its already designed in such a way that you could rig that in seconds. By simply running the anterior attachment cords for the upper lid compartment down to where the bottom compartment wrap-wall attaches to the main compartment front panel you create the proper anchor point and then the whole top of the pack slides down and compresses without effort. But that might mess up how the load-lifter mechanism works, as it uses the higher position of the upper lid compartment for mechanical advantage to lift the bottom section up.
But, I love that such a suggestion was immediately implementable by the current design features (despite being fairly minimal). One of the things I did with this was trying to make each design feature do double-duty whenever possible. Just like gear, each feature needed to satisfy mutliple needs/uses.
Thanks for that idea, it helps me tighten up my design where ever mental weakness still exists in the design.

The ideas and help that you get is great.
You had mentioned using tent poles for rigidity. why not rig them in a sleeve and they could be your load lifters , thus freeing your top lid to be part of the compression mechanism. In this case you could vary what you carry in the middle. (sorry,but my mind is still infuenced by my modular pack that I just made)
P.S. check out Daryl"s pack – he uses a u channel made out of alum or carbon fiber to transfer weight to the hip beltJun 4, 2011 at 7:08 pm #1744997

Great Cad drawings of the pack I wish I had that talent, I still rely on my hand drawn drafting skills.
The design is pretty cool the internal compression was used on older heavier packs of Yak paks,Dana designs, Vortex packs in different ways of configuring straps. The pack looks like a very progressive design and very cool.
From the drawings the pack looks to be about 8 to 10 inches deep. The pad in the sleeve frame should not be on the outside of the pack or it will push the load away from your back put stress on your shoulders pulling away from your back. The pad should be in a zippered pocket that needs to go inside the pack and half of 3/4 lenght pad thickness goes inside the pack and the other part stick through 3d foam or nylon. You need to make the pack back 11.75" wide at the stitch line to allow the Z rest pad virtual frame to work correctly 20 " tall.
