Abstract:
A method for designing and optimnizing compliant mechanisms is provided, in addition to bistable compliant mechanism designs. According to the method, a selected compliant structure may be modeled analytically, and the characteristics of the analytical model may be optimized. Multiple recursive optimization algorithms may be used, for example, to determine the general location of a global optimum, and then to determine the values of the analytical model characteristics that obtain the global optimum or a feasible configuration for the selected compliant structure. Geometric characteristics of the selected compliant structure may be derived from the values of the analytical model characteristics. Bistable compliant designs may have a shuttle disposed between a pair of base members. The shuttle (20) may be linked to the base members (22, 24) by a pair of legs (30, 32), via flexural pivots. The base members may have cantilevered mounting beams to create deformable mounts that receive and store potential energy. The stable configurations are those in which the stored potential energy is at a relative minimum.

Abstract:
An elastomeric load bearing surface with different load support characteristics in different directions. In one embodiment, the surface includes an elastomeric membrane that is oriented in only a single direction, for example, by compression or stretching. In another embodiment, the surface includes mechanical structures, such as connectors, variations in thickness and apertures, that vary the load support characteristics in different directions. In another aspect, the present invention provides a multilayer load bearing surface in which the layers cooperate to provide a controlled force/deflection profile that is variable in different regions of the surface. In one embodiment, the upper layer includes a plurality of loosely connected nodes and a lower layer having a plurality of resilient elements that separately support each node.

Abstract:
A suspended pixelated seating structure provides ergonomic, adaptable seating support. The suspended pixelated seating structure includes multiple cooperative layers to maximize global comfort and support while enhancing adaptation to localized variations in a load, such as in the load applied when a person sits in a chair. The cooperative layers each use independent elements such as pixels, springs, support rails, and other elements to provide this adaptable comfort and support. The suspended pixelated seating structure also uses aligned material to provide a flexible yet durable suspended seating structure. Accordingly, the suspended pixelated seating structure provides maximum comfort for a wide range of body shapes and sizes.
