Geometric Logic: Evolution from the Hoberman Wheel
The wheel follows the simple geometric relationship between the linkage and joint system: as long as the joint positions are maintained equidistant to one another in the horizontal direction, the linkages can freely be designed.
Hollow Construction Method
The assembled shape of the linkages is inspired by animal vertebrate that provide maximum strength with minimum material. The linkage parts are cut with CNC router and then assembled as if making a guitar. The short horizontal pieces inside the hollow construction act like I-beams to provide additional support to withstand bending in the lateral direction. The contrast of the lightweight linkages and robust joint assembly accomplishes smooth opening by one person.
While the linkages are lightweight, the top and bottom supports need to be structurally robust to support these linkages’ weight as well as to ensure that their joint positions are maintained during rotation.
Solid 1.5 inch plywood arms are press-fitted and bolted to the disk to reduce lateral and vertical moments at joint connection at the far end of each arm. This design does not require extra braces and emphasizes the vertical continuity of the linkages.
