A big bulky case is necessarily the only way to prevent bending. In my head, I'm thinking that the aluminum band could add more rigidity compared to a bulkier case with thick TPU and PC components.

I have a theory, and I'm gonna butcher it trying to explain my thoughts of it. Picture a wooden 2x4 post. If you lay the 4inch side flat and bend it in the middle, it will flex. Flip it so the 2in side is on top and bottom, and try to bend it again. It'll flex but not nearly as easily. So if you scale this 2x4 theory down to a bumper case for the iPhone, then it would give you my theory as to why an aluminum bumper could be just as, if not more, rigid than a thicker "rugged" style case.

It's just that not many people have purchased an aluminum bumper due to the fact that aluminum can lead to a slight lose in reception

Good description of how a relatively thin "I-beam" bumper could add structural rigidity. The problem as I see it is how to secure the aluminum bumper to the iPhone. Binding it firmly around the iPhone could work, but then it offers no shock protection. Any TPU layer between the bumper and the phone would be too compressed to absorb shock. Perhaps the way to go is an outer TPU sleeve fitted around an inner metal bumper which is tightly bound around the iPhone, but then it's bulked up.

Here's an interesting design I found on ebay:

They claim it's shockproof but if it screws down tightly the pads will compress too much to do any good. It doesn't hold the screen off a flat surface, either. Oh well, it's almost a good try!

So what if we took Spigen's design, and replaced the metal band with the design you shown from eBay? Screwed too tight, and the TPU band gets compressed, so the screws and holes in the aluminum band are only a certain length/depth to prevent overtighten. Unless the hole becomes stripped, then it could be user error, or sent from the factory. In which case, is replaced for free.

That's not Spigen's design, it's a KO of the Draco/Deff Cleave bumper that's been around since the iPhone 4

My mistake. Who is Draco?

EDIT: Nevermind. Did some research. When I said "Spigen's design" I was referencing the aluminum band paired with a TPU liner. It appears Draco just uses an aluminum band with pads and no TPU, unless I missed something.

I saw an aluminum bumper somewhere on this forum. It was one piece of aluminum, but it hooked together at the top of the phone. You'd spread the band slightly apart, enough to slip your phone into the grooves, and then the band would hook together like a puzzle. I'm not sure exactly if that's how you are to put it on your phone, but that's my guess.

What if we used that design of aluminum band with a TPU liner? There wouldn't be any screws to be overtighten, and the tpu wouldn't be compressed since the aluminum band is designed to match with the TPU liner.

I feel like an aluminum band would be more superior to adding rigidity than a rugged style case. If only I had money to patent these designs.

Try it and see what happens. Those aluminum bumpers are cheap enough to experiment with. I doubt you'll get it to clasp shut around a TPU liner, but you could add some thin padding material inside the bumper if needed.

As for it adding structural rigidity, remember that they're using a cheap aluminum alloy that's easy machine due to its softness. The ones on the market are mostly ornamental with a little shock protection as afterthought - even that $100 Draco. :rolleyes:
 
While I love a naked iPhone... I had to settle for gold when I wanted space gray (I know first world problems... I got the last plus so I took it). I found an insignia soft shell case at best buy for $15 I decided it would hold me over until I figured out what I really wanted. I really like it (plus it's purple, always a win with me)ImageImage

Amy, you should check your emails!
 
I have 3 cases presently, each of which serves a different purpose. I have an Incipio NGP in black, a black UAG (got that for free) and a Pelican Protector. All offer varying protection.

As much as I really wanted to run naked with my iPhone 6 Plus - 128 GB - Space Gray... as much I liked the cold metal feel in my hand... It just didn't seem like a wise move. Today, I picked up an Invisible Shield Glass screen protector and a Pelican Progear Voyager case.

Have two cases, I just have the 6 Plus less than a week now.

Have the Apple Olive Brown leather case, fits great and is really nice and soft, looks classy also.

Also have the Ringke Flex Slim Fusion, this fits nicely and is priced very well.

I'm going to try and restrain myself on buying too many cases like I did on my last few iPhones...
 
I'm not sure if this one has been shown, but here is my case. Spigen Neo Hybrid Infinity White. I had one on my 5S and I had to get another one for my 6+. (don't judge me on my PS skills, I just like to fiddle with it every now and then)

Nice pictures! What screen protector do you have, and how did you put it on so perfectly??
