ABSTRACT:
A motion impartation device having a driving portion; a driven portion engaged with the driving portion such that at least one gap separates the driving portion from the driven portion; and a structural element disposed in each gap such that a first compressive force is transferred from the driven portion to the driving portion and a tensile force is transferred from the driven portion to the driving portion. Each structural element including a compressive and a tensile structural element. The compressive structural element having a first enclosure defined by first walls surrounding a first cavity. The tensile structural element having a second enclosure defined by second walls surrounding a second cavity, a first non-compressible material disposed in the first cavity, and a second non-compressible material disposed in the second cavity. The first walls are shaped such that the compression force tends to compress the compressive structural element by a first deflection causing an amplified second deflection of the first walls into the first non-compressible material. The first walls exert a second compressive force against the first non-compressible material, resulting in a resistance to the first deflection and the first compressive force. The second walls are shaped such that the tensile force tends to elongate the structural element by a third deflection causing an amplified fourth deflection of the second walls into the second non-compressible material. The second walls exert a third compressive force against the second non-compressible material, resulting in a resistance to the third deflection and the tensile force.
