Canon patents a huge, hinged and reversible DSLR LCD

A newly published Canon Japan patent might reveal the future of Canon DSLR LCD screens… and that future is massive and flippable. Originally spotted by Canon Rumors, the patent details a hinged rear LCD that is so big it hides all of the controls on the back of the camera underneath it.

As you can see from the diagrams (or read in the patent itself) the LCD is capable of lifting upward, then reversing, and is specifically designed to avoid obstructing the camera’s viewfinder. This makes it possible to view an image from the uplifted LCD and use the viewfinder during the same session.

While a hinged DSLR rear display is nothing new, Canon’s patent shows a design that would allow for a large and reversible display unlike anything we’ve seen before. In fact, the LCD shown in the patent’s illustrations covers the entire back of the camera, making it necessary to tuck the rear dial and several buttons behind it, though several others are exposed on either side of the viewfinder.

As with every patent, there’s no indication of whether or not Canon has plans to incorporate this design into an upcoming camera, but it’s one of the more curious Canon patents we’ve run across.

Reversible Concrete: 3D Printing for Easy Deconstruction & Reuse

Reinventing one of the world’s most ubiquitous building materials, this concrete alternative developed at MIT can be 3D-printed then disassembled without wasting unnecessary energy or creating useless debris. Imagine the possibilities temporary concrete architecture that is easy to deconstruct with zero material loss.

Rock Print effectively shoves rocks into position, binding them with computer-controlled string. The result in this demonstration at the Chicago Architecture Biennial is a rigid 13-foot column that can be cleanly unraveled into its constituent parts.

A product of the Self-Assembly Lab at the Massachusetts Institute of Technology, this approach suggests a new way to think about concrete, a material that is typically cheap and easy to use in construction but expensive and wasteful when it comes to demolition.

As Skylar Tibbits explains, “We are using a similar technique to powder-based printing. There is a container, material is deposited layer by layer and a ‘binder (in this case the string) is applied to each layer in the specific pattern of the slice.”

Effectively any shape is possible thanks to the 3D printing process, while the results are strong and durable, relying on the physics of jamming and collective strength of composited stones. Even more importantly, the reversibility of the process makes this a far more eco-friendly way to build rigid structures from durable materials that still dismantle on demand.
