Inspired by Descartes’ polyhedron "total defect“ discovery, and by R Buckminster 

Fuller’s work in his ‘Synergetics’ studies, Dick Fischbeck recognized there was a unique 

efficient solution for a new dome structure. He named it, ‘RanDome’. Dick was granted a 

patent for his RanDome in 2008. He also licenses it under “Creative Commons” thus 

allowing anyone to build and distribute the structure for non-commercial purposes.

An Introduction to The Randome

The design of the randome provides a spherical or near-spherical structure that is made of elements that are simple and inexpensive to manufacture and to assemble. Unlike previous geodesic dome designs, which required exacting measurements and were generally limited to spherical forms, the randome is a structure that is versatile in form and not restricted to the form of an icosahedron. The randome can be easily assembled without requiring complex mathematical calculations and without having to arrange the elements in a pattern along predetermined great circle gridlines. As the name implies, the randome design functions not so much as a design template, but as a modular construction system with a high degree of flexibility.

The flexibility of the randome is achieved by providing a geodesic structure made of convex-concave elements that are arranged in an approximate manner, either with the aid of a simple spiral pattern, or more or less randomly. By "approximate" is meant that the elements are assembled one next to the other according to some principle such as overlapping or tangentially touching adjacent elements, yet randomly in the sense that particular exemplars of the elements do not necessarily have to be placed or fastened along predetermined great circle gridlines, nor do they have to be placed in a particular sequence or at a particular location. The example of a dome for human shelter will be used to describe the basic geodesic structure according to the invention, although it should be understood that a complete geodesic sphere, a semisphere, or an irregularly curved structure can also be constructed in a similar manner, and that geodesic structures constructed according to the invention are not restricted to a certain size or to certain applications, such as shelter for humans.

Clinton's Equal Central Angle Conjecture

Since first proposing the conjecture stated herein in a paper to the 5th International Conference on Space 

Structures, held at the University of Surrey, Guildford, UK on 19-21 August 2002, it has come to my 

attention that Dick Fischbeck Ref 16 has been working on similar problem. He randomly arranges cones 

of consistent diameter on the surface of a sphere based on the spherical excess angle of a polyhedron. He 

has also proposed a variation where the central angles of the cones may consistently generate random 

tetrahedral pyramids that will tessellate the sphere. Perhaps a careful study of his RanDomes will provide 

a solution to the Goldberg polyhedra equal central angle problem.

The RanDome

Buckminster Fuller is well known for his determined effort to address the global shelter shortage by using his concept of Comprehensive Anticipatory Design Science. Design science strategy focuses on using the world's resources to the greatest advantage possible. One measure of a dwelling's success is its performance per kilogram of material. By increasing a material's performance through design, and thus the efficacy and efficiency of both the cost and labor of construction, the possibility for sheltering all the world's population will also increase.
Fuller made great progress in his efforts to address the problems of shelter. The geodesic dome is a milestone in the history of shelter. The RanDome is an advancement in building design that will take Fuller's geodesic shells to new levels of functionality and versatility. The RanDome is a new kind of geodesic shell which is far simpler than existing space enclosing building strategies. RanDomes are mass-produced and assembled from a variety of materials. RanDomes are inexpensive, strong, long lasting and weatherproof - exactly the type of structure to address the global problem of inadequate shelter.
The RanDome achieves these benefits by changing, fundamentally, how we view the basic building element. The RanDome structure is not an assemblage of edges and faces, as are traditional shell structures. It is assembled from a number of overlapping cones called vertex elements. A RanDome has all the structural benefits of a traditional geodesic shell structure but without the complexity of design, manufacture and construction. The RanDome construction strategy is intuitive. It is a Trimtab improvement on mass shelter construction by virtue of elegant simplicity. This building strategy needs no advanced educational degrees or construction experience. It transcends literacy, language and cultural barriers. Everyone, even children, can now build a sturdy, weatherproof and healthy shelter.
A RanDome intended for human shelter is assembled from numerous identical vertex elements. Vertex elements are cones. A cone is fabricated from a sheet of material. We use a typical sheet in the shape of a circle, square or rectangle, whose maximum dimension is usually one meter. The semi-rigid sheet material can be any kind available. The preferred material is weather-, insect-, rot- and fire- resistant. Examples of suitable materials are metal, corrugated plastic, plywood, cardboard, fiberboard, fiberglass, or similar products.
That all vertex elements are identical leads directly to manufacturing efficiency. When one is fabricating a large number of identical elements, the economies of scale and ease of process are best taken advantage of.
This is a construction method previously unknown and unexploited. Some basic mathematics can be used to explain our unique approach. Until now builders have assembled their structures using only two of the three topological features. Leonard Euler discovered 257 years ago that all polyhedrons can be reduced no further than into edges, faces and vertexes. For example, a cube has 8 vertexes, 6 faces and 12 edges. People build shelters using face elements or edge elements. People do not yet build shelters using vertex elements. The basic building component of a RanDome is a vertex element and this makes all the difference.
Cones are simple to calculate and easy to fabricate. The fabrication begins with a flat sheet of building material. An angle is made in the shape of a narrow triangle from the center to the perimeter of the sheet. The sheet is then cut and lapped, or folded without cutting, according to this angle, to create a vertex, thus producing a cone element. The angle of this lap or fold is determined using simple mathematics. The relationship of the individual angle in degrees to the whole structure is 720/n, where n is the number of cone elements employed. For example, if 100 sheets are used for a half-sphere structure, the required angle is 360 degrees divided by 100 pieces, or 3.6 degrees per angle.
The cones can be mass produced and stacked efficiently for shipping. They are assembled on-site, or pre-assembled before deployment, by anyone using a technique similar to shingling a roof. The elements are overlapped just as one would overlap shingles on a traditional roof. The upper element extends outside and over top of the lower element. Rain water is forced to shed onto the ground. Leaks are virtually impossible. Elements are attached to each other with common fasteners such as nuts and bolts or rivets. Double adhesive tape, magnets or clamps hold the elements in place during this fastening process. Each fastener is made weather tight. Erection of the shell structure can proceed from the top to the bottom or the reverse. Top down erection is preferred, raising the structure during the process of erection, to allow all work to take place at ground level. Doors, windows and vents are installed in the traditional manner, adding frames where needed.
One of the fascinating and beautiful aspects of the RanDome is that the placement or arrangement of the structure's elements during erection is done in an approximately random fashion. No precise measurements are required. Elements are overlapped and fastened together with a predetermined average distance between cone vertexes. A 50% overlap of the cone elements is typical. In climates with heavy snow and wind loads expected, or when the available sheet material is relatively thin, overlap will be maximized to strengthen the shell. Double and triple layers of elements are desirable depending on the expected function of the shell structure. This layering makes possible very strong domes using very thin sheet material. In extreme climates, either very hot or very cold, two or three concentric shells with an air space between the shells will be useful. For added strength, these shells can be bridged with short connectors such that one shell supports the other. Finally, with slightly more complexity, any shape RanDome is possible just by varying the cone angle of the elements of a particular structure.

Though visionary technologists such as R. Buckminster Fuller developed low-cost modular housing prototypes as early as 1927 which were factory produced, deliverable by helicopter, and highly durable, their use was never adopted. Building codes and construction trade rules alone killed Fuller’s idea, and today housing continues to be built using designs, materials and codes in use for over a century.
