Abstract
A tensegrity structure is formed from a plurality of interconnected tensegrity modules. Each module includes several column-like compression members and tension elements run between ends of the compression members to define a polyhedron. The tension elements form the edges of the polyhedron and intersect at the vertices of the polyhedron. The interconnected modules are joined to each other with triangular faces abutting but with the edges and faces of the abutting triangular surfaces of the respective modules rotated 180.degree. away from superposition and with the vertices joined to tension element edges, being joined at a point located one-half or one-third of the way along the length of such edge.
Claims7
A tensegrity structure comprising a plurality of interconnected octahedral tensegrity modules:
- each octahedral module including three columnlike compression members and twelve tension elements extending between the respective ends thereof, said tension elements defining the twelve edges of an octahedral geometric figure having eight triangular faces, the tension elements intersecting at the respective vertices of said octahedral geometric figure,
- each octahedral module being interconnected with another octahedral module with portions of their respective triangular faces abutting each other,
- but with such abutting triangular faces being relatively rotated 180.degree. away from superposition with respect to each other,
- a vertex of each abutting triangular face being joined to the midpoint of an edge of the abutted triangular face,
- said structure having a surface with one triangular face of each of said octahedral modules lying in said surface, and
- said surface having the appearance of an array of triangles interlaced with three-sided tetrahedral-shaped dimples.
A tensegrity structure comprising a plurality of interconnected tensegrity tetrahedron modules:
- each tetrahedron module including four column-like compression members and six tension elements extending between the respective ends thereof, said tension elements defining the six edges of a tetrahedron geometric figure having four triangular faces, the tension elements intersecting at the four vertices of each tetrahedron module,
- each tetrahedron module being interconnected with another tetrahedron module with portions of the respective triangular faces abutting each other,
- such abutting triangular faces being relatively rotated 180.degree. away from superposition with respect to each other and also being shifted laterally with respect to each other by a fraction of the width of said abutting triangular faces,
- a vertex of each abutting triangular face being joined to an edge of the abutted triangular face at a point offset from the midpoint of said edge.
A tensegrity structure comprising a plurality of interconnected icosahedron tensegrity modules:
- each icosahedron module including six non-intersecting column-like compression members and thirty tension elements extending between the respective ends thereof, said tension elements defining the edges of an icosahedron geometric figure having twenty triangular faces, the tension elements intersecting at the vertices of said icosahedron module,
- each icosahedron module being interconnected with another icosahedron module with portions of the respective triangular faces abutting each other,
- but with such abutting triangular faces being relatively rotated 180.degree. away from superposition with respect to each other,
- a vertex of each abutting triangular face being joined to the midpoint of an edge of the abutted triangular face.
The method of constructing a tensegrity structure comprising the steps of:
- providing a plurality of tensegrity polyhedral modules each having triangular faces,
- interconnecting said tensegrity modules by abutting a triangular face of one module against a triangular face of the adjoining module,
- each two interconnected modules having a vertex of the triangular face of a first module joined to an edge of the triangular face of a second module and a vertex of the triangular face of the second module joined to an edge of the triangular face of the first module,
- said abutting triangular faces of the two adjoining modules having the vertex of one offset from the midpoint of the edge of the second,
- whereby the abutting portions of said triangular faces are parallelogram-shaped, and
- the overall configuration of a side of the tensegrity structure has two pluralities of pyramidal-shaped dimples of different sizes.
