LIMITED EDITION COLLECTION

We designed this collection specially for our first crowdfunding campaign at indiegogo   Through this campaign we want to start a permanent worldwide distribution, to reduce the prices of the most popular products, to prototype and develope a special collection for children.   The collection is inspired by the common approach of making the different types of elements using different types of wood often used by burr puzzle makers. It is very appropriate especially when there are different elements that look the same in assembled position. This stylistics emphasizes the tectonics of the structure, unveiling a little bit of the hidden assembly principle. This sensation is even stronger when using very contrast types of wood textures, from almost white to almost black, together with more colorful types.   This principle is applicable for most of our designs from Sliding and Impossible collections. Only 1x3 and 1x6 are not appropriate because they are composed of only one type of element. Some of the puzzle tables, like 2x3 and 4x3, have several different set ups, giving more permutations; hence more variability.

about

PRAKTRIK is a studio and brand focused on “practical” “tricks”.   All products are inspired by burr puzzles. We see great potential for facilitating their principles for utilitarian purposes. Their production requires no hi-tech, they can be made of natural, ecological, and healthy (harmless) materials, they are assemblable and disassemblable, they can also be fun.   Such puzzle structures are geometrical and constructivist on one hand and mystical on the other. This mystery brings some emotional quality to such designs that we consider very important nowadays. They also stimulate and require some intelligence from the user which is also very important to us.   Most of such known puzzle examples are too complicated and their parts are difficult to manufacture; as a result, new ones had to be found. During the geometrical analysis it became clear that this task was just the opposite of the one of a classical puzzle maker because the new solutions had to be as simple as possible and easy to assemble. Generally, three interlocking principles have been used: The first one is represented by structures (4x6, 5x4, 6x3 ...) that are theoretically “impossible” to be assembled at least in our tri-dimensional world. They can become reality only by leaving enough distance between the faces of the element notches and applying some pressure during assembly. These burr structures are interlocked in all directions and are independent of their orientation in space and gravity.   The second one is represented by structures (1x3, 1x2+1, 1x6, 2x3, 4x3... ) that can be put together by sliding motions. It can be sliding of the wooden pieces one after another (1x3, 1x2+1), half of them after the other half (1x6, 2x3, 4x3 ), or all of the elements together (1x3, 1x2+1, 1x6, 2x3, 4x3... ) as a coordinate-motion (slide-together) structure. Such mechanical puzzles are locked only in some directions and most of them depend on gravity in order their parts to stay together.   The third principle is represented by structures (VST, VIIC, XIIL, IXT1, VIMB....) that can be put together by moving all parts simultaneously. Such puzzles are named “coordinate motion” or “slide together”. Once assembled, the whole structure stays stable even one tries to move one or several of its parts. The stability in this case does not depend much on orientation and gravity. The name of a particular piece of furniture comes from the logic of its structure. For the “impossible” and “sliding” pieces it consists of the number of different element types multiplied by the number of elements of each type. The whole mathematical expression gives the total number of wooden parts. For “coordinate” collection the name consists of the total number of elements represented by Roman digits followed by letters representing the function - “S” for stool, “T” for table etc. Some of the principles we found appeared to be part or a step of more complicated puzzle structures (1x3, 1x2+1) and other appeared to be already known to other inventors (1x6) - Rinus Roelofs and his 6 piece slide structure (mortise-and-tenon joint). There are still numerous practical burrs waiting to be discovered and some of the wooden “knots” presented here to be used in other fields different from furniture design.   Praktrik Ltd product designer: Petar Zaharinov webmaster and manager: Delyan Spasov visual identity: poststudio photography: Martin Filkov     Facebook Google+ Twitter YouTube
