Double Infinity is acollaborative exhibition by Holland Van Abbe Museum and Arthub, commissioned byHolland Art Center. It is opening coincideswith the opening of the Shanghai World Expo and is aimed at connecting thesetwo countries, China and Holland, and twocities – Shanghai and Eindhoven. The aimis to conduct an impressive virtual dialogue by sharing the respective dailyconditions and spatial features. Thereare two main parts which comprise the exhibition. The first is the collections of the Van AbbeMuseum, the second consists of individual creations by specially invited Asian artists. The name of the exhibition, DoubleInfinity, means to circulate and transcend oneself time after time. HHD_FUN was invited to design the exhibition space,which manifests as a spatial artwork reflecting the designers’ interpretationof the Double Infinity concept.
The design inspiration comesfrom the theme of the exhibition. Theconcept tries to introduce infinite circulation into the spatial design of the exhibition.After the consideration of many infinitive-circulation mathematical-models andthe interaction between the site and display items, it was decided that the circulationwould be a ∞ shape. Although it is quitea coincidence that this is also the mathematical symbol for infinity, thedesign was not conceived as a metaphor based on meaning of the simple symbol. The concept of the initial design consisted ofthree-dimensional infinitive circulations, afterwards because of time and financialconstraints; the circulation was changed to a two-dimensional concept. The former crosspoints of the three-dimensional design turned into the crisscross of thetwo-dimensional concept. This providesthe visitors with a junction point, from where they can choose content toexplore. This configuration alsoprovides multiple visiting routes.
Owingto an important focus on cultural communication between these two countries, itis anticipated that this exhibition will go on tour. As such, all the structures are made of thedismountable steel frame and tension fabric. The complicated three-dimensionalstructures actually consist of topologically equivalent triangles. The reason for using the triangle here is stability:once the length is set, the shape and size can not be changed. Unfortunately, thetwo-dimensional geometric construction restricts the scope for spatial topologicaltransformation. In order to increase the stability of the spatial structure, additionalstructure was added to the corners of the triangles, so that small trianglesare formed on every corner, successfully increasing stability. By means of topologically-equivalent transformationand combination, the final design responds to site requirements. The last step in the process is to bind up thesteel frames tightly with the tension fabric.
Thecorner structures are based on consecutive circular arcs of varying radii. This makes it much easier to manufacturethem. Using this approach, it is possibleto produce the complicated spatial curves using low-tech construction methods.
Thetriangular structures and their equivalent topological transformations, incombination with the tension fabric, form a design and construction principle whichcould be used under different conditions to respond to particular siterequirements.
