TRANSFORMABLE/ DEPLOYABLE STRUCTURES

CAROLINE YANSON

INTRODUCTION I am exploring the design of Transformable/ deployable structures by building a model of a Hoberman Sphere & 3D printing my own joints with the goal of understanding how these structures work via the “scissor hinge”. Transformable/deployable structures are expandable & contractable for storage, transportation, reuse, & adaptability (DeTemmerman, Roovers, Mira, Vergauwen, Koumar, Brancart, Mollaert, 2014). They evolved in history starting from their use as Egyptian hunter chairs & Mongolian nomadic yurts (mira, 2014) (Figure A). Today, applications of transformable/deployable structures are widely used in everyday objects: umbrellas, store gratings, tents, foldable furniture, & more (Figure B). Designer, Chuck Hoberman, increased the popularity of these structures from his creation of the Hoberman Sphere (Figure C). His work, among other designers’ work, have inspired more interpretations & developments of these structures.

FIGURE A: Transformable/ Deployable Structures in Historic Applications

Egyptian Hunting Chair (Pamperin, (n.d). Mongolian Yurts (Arneill, 2017).

FIGURE B: Everyday Applications FIGURE C: Designer, Chuck Hoberman Transformable/deployable structures apply today in many fields: the military uses them as shelters, NASA uses them in space exploration, the medical field uses them as temporary care units in disasters, etc (Merchan, 1987). The possibilities of such structures are endless! These, though complex & intricate, can be designed & produced in an easier manner via AEC technology, such as softwares, Rhinoceros & Grasshopper Plug-in, Karamba . AEC programs perform simulations, model structures, & calculate algorithms ensuring stability, geometry, & effectiveness. AEC allows the architect, engineer, or contractor to understand the structure & assembly. Then, they can either manually assemble or digitally fabricate the structure. Because transformable/ deployable structures have little available/ easy softwares for the general public (DeTemmerman, Roovers, Mira, Vergauwen, Koumar, Brancart, Mollaert, 2014)., I predict that there will be a future trend of easy-to-use software development aiming accessibility to a wider audience (Figure D). I also predict that transformable/deployable parts will be designed for mass production to make assembly more efficient.

FIGURE D: GARTNER HYPE CYCLE FOR AEC TECHNOLOGY

CASE STUDY 1: Universal Scissor Component, Workshop Led by Niels De Temmerman, London, 2011 (Mira, 2014) This is the development of a universal scissor component (USC) used in an icosahedron scissor dome made of wood. They used Rhino to create a parametric model & Karamba for structural analysis & mathematic algorithms. The parts were laser cut MDF boards manually connected to wooden struts by bolts. This design is reducing the number of materials, & therefore, waste, by designing for adaptability & structural reuse of the USC. In theory, scissor components in transformable/ deployable structures, are complex & generally designed for a single purpose. By creating the USC, it makes it simpler to design a transformable/deployable structure because the scissor component can be mass produced & applied to different shapes & sizes of such structures. The adaptability of a uniformed component will ultimately lower the production cost & make it easier & faster to set up & take down.

CASE STUDY 2: The Hoberman Arch, Chuck Hoberman, Salt Lake City Utah, 2002, ( Hoberman Arch, 2020). This structure is a motor operated aluminum arch with rigid covers that acts as a stage. It expands & contracts like an “iris of a human eye”. Hoberman employs his prior design of a scissor-hinge mechanism, but adapts it by angling the hinges in a ring & attaching 2 of the same angulated bars to a revolute joint. As a result, he created the largest transformable structure of the time. By attaching the rigid covers to the parts of his structure with angles, the covers did not get in the way of the motion of this structure. Hoberman’s use of rigid covers provided safety and shelter from weather conditions & avoided many of the problems that membrane covers had for other designers in the past.

CASE STUDY 2: WINTER OLYMPICS HOBERMAN ARCH

Hoberman Arch’s Motorized Structure with Rigid Covers (Hoberman Arch, n.d).

CASE STUDY 3: Transformable Dome, Iran, Maziar Asefi & Soheila Aram, 2017 (Asefi, Aram, 2018). This design is a transformable dome that uses rigid covering panels to cover the space when expanded. The rigid covers are attached to the interior of this surface, giving the benefit of extra warmth in cold places. It is smart to use detached rigid covers for it allows the installation to act as unitized modules. That way if one of the cover panels needs repair, they can do it without having to dissemble the whole thing. They designed this model through the computer model of Rhino, then manually assembled the pieces. Overall, they created a great precedent from which others can 76 learn stability, weather protection, & more.

HYPOTHESIS If I learn possibilities of transformable/deployable structures, model 1 out of K’nex pieces, & finally, 3D print scissor hinges, than I will have a comprehensive understanding of how these structures work in regard to the AEC industry PROCESS I am exploring how transformable/deployable structures are assembled & how they expand & contract in different forms. I completed my project in 3 parts: PART 1: WOLFRAM SOFTWARE SIMULATIONS I logged into the Wolfram software & visited “Scissor Hinge Simulation” (Berczi, 2007) , “Expanding Fence Simulation” (Kabai, 2007), “Expanding Tower Simulation”(Kabai, 2008), & “Deployable Shelter Simulation”(Kabai, 2020). I experimented by changing the control variables that go into making the components of such structures. PART 3: 3D PRINTING SCISSOR JOINTS I wanted to learn how to 3D print, so I am 3D printing a 3D & 2D scissor hinge. The first step was finding a computer model of a Hoberman Sphere so that I could extract the 2 forms of scissor hinges to 3D print. I found a model that was already made on Thingiverse (Badro, 2014)- a website of shared, 3D models that the public can use to 3D print.

In total, the actual time it took to 3D print was only 3 hours. t to oo ok k to o 3D D p 3 ho ou urs sr .t t wa aw s s on o ly ly 3D PRINTING PARTS PRINTED- NOT ASSEMBLED

PART 2: MODELING A HOBERMAN SPHERE OUT OF K’NEX TOY PIECES To model a Hoberman Sphere, I followed a tutorial (Mosely, 2017). To begin, I collected the K’nex pieces I needed to build the model.

I assembled the 2 scissor hinge types. I had some difficulties fitting some of the pieces together, so I took an Xacto knife & cut out excess material that resulted from the 3D printing process. I also printed cap pieces, but it turned out that I did not need them. Overall, the process was educational & I accomplished my goal of showing the 2D & 3D scissor hinges.

ABOUT ME

JACKY YAN

ARCHITECTURE IS ABOUT TRYING YO MAKE THE

WORLD A LITTLE BIT MORE LIKE OUR DREAM

BACKGROUND

After I started learning architecture, I came into contact with a lot of new things, started to touch some computer modeling software AutoCAD, Sketchup, and also learned that Photoshop, InDesign, Illustrator is not only used to make posters, but also to modify and type our drawings. What makes me feel most incredible is parametric modeling. By learning and consulting, we know that many things in life are inseparable from numbers, like big data, finance, design, and many of the most basic things in software are numbers. Digital has influenced the development and future of cities, like digital cities, digital modeling. Parametric modeling is one of the representatives of digital modeling, parametric modeling is free modeling through numbers, formulas, and software. Why free modeling is because you can build whatever arc you want, whatever shape you want. Model production in a purely digital space is simply a transformation of ideas for designers, allowing designers to greatly enhance their designs, diverge their thinking, and create different buildings. Rhino is the most representative software because it is a parametric modeling software that was molded earlier and contains very functional software Grasshopper. In the process of learning this software, I found that the biggest difficulty is that it has too many functions, there are many small functions in each big function, you need to spend a lot of time to practice in order to better master this software. But I really enjoy the process since Rhino is more like a game software than a model software, it lets you think of design as an interest, love a favorite thing to do, you don’t think it’s boring, because you can find more inspiration here.

Capabilities and Applications of 3D Printing

Whereas massive industrial machinery in special workshops used to produce parts, today 3D printing helps. Using this technology, it is possible to print parts of different complexity, which are not inferior in quality and characteristics to those produced by traditional methods.

3D printing technology

Printing on a 3D printer consists in the layer-by-layer formation of the structure of the future part from its graphic representation compiled on a computer in the form of files with three-dimensional graphic structures. They are created manually using specialized software, or obtained by scanning a real prototype.

Printers are capable of recreating parts from sheet, liquid or powder material. The possibilities of a 3D printer in terms of the use of material for printing are very wide - it can be:

  • plastic;
  • nylon;
  • glass powder;
  • metallic powder;
  • building mixtures;
  • other materials.

The future details are obtained by fusing layer upon layer in such a way that their shape corresponds to her digital prototype.

Techniques used

3D printing can be done using different techniques.

  1. Extrusion printing consists in heating the base material to the melting temperature and extruding it through the extruder nozzle, forming fragments of the future part. Various polymeric compounds act as the starting material;
  2. The powder technique involves inkjet printing, in which binders are applied to a thin powder layer, followed by impregnation with wax or a polymer composition. Next, sintering of adjacent powder layers is performed. For this, direct or selective fusion with a laser or cathode ray tube is used;
  3. Laminating opens up wide possibilities for 3D printing. Using this method, you can significantly reduce the cost of manufactured spare parts. This technology involves the use of paper, sheets of thin plastic and metal as the base raw material.

Applications

Since 3D printers can create parts of a wide variety of shapes, 3D printing has become used in various industries. Most often it is used in:

  • industry;
  • medicine;
  • construction;
  • automotive industry;
  • aviation.

Advances in technology and declining prices for 3D printers are driving their widespread adoption at the consumer level. Anyone who is at least a little versed in technology and has free financial resources can start home production of the necessary things and parts.

3D printing at home

If earlier everyone wanted to have a regular printer for printing documents, photos, presentations at home, today desires have switched to a 3D printer. Why might it be needed at home? Given the almost unlimited possibilities of 3D printing, a printer at home will become not just another high-tech toy for technology lovers, but an essential tool for the home. With it, it will be possible to print-produce:

  • elements of furniture fittings;
  • Christmas tree decorations;
  • stands for office supplies;
  • clothespins;
  • Kids toys;
  • chessmen;
  • original protective cases for tablets and phones.

Having a 3D printer at home will eliminate the unnecessary waste of time searching in stores and the market for some small detail that you can now make yourself.

Medicine

An important point in the development of 3D printing technologies is that they can be used in medicine. The most common use of 3D printers is in dentistry. They help to quickly make jaw implants and temporary crowns, which are necessary for a full life of the patient. The manufacture of jaw implants on a printer greatly simplifies the work of a dental surgeon.

In addition to jaw implants, other complex elements necessary for the restoration of the human skeleton can be made. For example, a modeled and then printed human skull implant made it possible to restore its integrity after a serious injury.

3D printing in medicine is actively used in prosthetics. Thanks to this technology, it is possible to produce prostheses that take into account the individual characteristics of the physical structure of the patient's body. By forming special microcavities in the prosthetic element, the possibilities of normal functioning of healthy tissue cells in contact with the material of the prosthesis are opened. This speeds up the process of human adaptation to the prosthesis.

Another successful example of 3D printing in medicine is the fact that scientists were able to grow a fragment of liver tissue using healthy liver cells. These samples are used to test and validate drugs on them. It is too early to talk about their transplantation to a person, but this is only for now.

In addition to printing parts used in the construction process, scientists are trying to create a printer that could be used to construct various buildings. Already today, the first construction 3D printers are being produced that can print-build houses with a total volume of 100-145m3. So far, it has not been possible to find the optimal solution that would satisfy civil engineers, but work on the introduction of 3D printing into the construction of houses is very active. Basically, they are aimed at creating a universal technique that can work with different building materials.

3D printing in construction will reduce human labor costs and injuries of builders, reduce the cost of building materials, and reduce the time required to build houses. At the exit, it is planned to receive a house ready for laying engineering communications, installing plumbing, electrical wiring, etc.

Industry

The purpose of 3D printing in industry is the manufacture of spare parts that are needed to restore the integrity or performance of components and mechanisms. The use of reverse engineering technology will allow you to restore the part in the presence of its whole or damaged prototype. Using 3D modeling, you can reconstruct the structure of a part and then print it on a printer.

If you need to change the functionality of the product, it is easy to make adjustments to its structure. To do this, you need to make the appropriate changes in the 3D model and then print the improved part. Thanks to different printing technologies and a wide choice of base materials, it is possible to produce parts with the required parameters. You can change their elasticity, strength, surface texture, color, etc.

Industrial 3D printing allows you to prototype future parts, print one-offs or start small-scale production.

Engineering Solutions has long introduced 3D printing technology and is ready to print products of any complexity.

The future of 3D printing

The prospects for the development and implementation of 3D printing technologies in various industries are very huge. If today 3D printers are used in several industries, then tomorrow it will be dozens of different industries. The most anticipated emergence of 3D printing in the following industries:
