An energy absorbing material includes a multi-cellular structure formed from a plurality of interconnected cells having a lattice structure. Each of the plurality of interconnected cells includes at least four nodes and at least one lattice element extending between each of the at least four nodes. The at least one lattice element has a diameter no greater than 2.5 mm.

A universal storage system for a motor vehicle includes an enclosure defining a chamber, a plurality of partitions, and a partition actuator for moving the partitions within the chamber to define a plurality of compartments. The system further includes a cover actuator for moving the cover elements to cover the compartments. The system further includes a user interface generating a deposit signal indicative of a size of an object to be deposited into the enclosure. The system further includes a controller generating first and second actuation signals. The partition actuator moves the partitions to the predetermined positions to define a compartment sized for receiving the object in response to receiving the first actuation signal from the controller. The cover actuator moves the cover elements to the predetermined locations for uncovering the compartment in response to receiving the second actuation signal from the controller.

A storage container having a locked position is disclosed, and includes a housing defining a cargo volume and an axis of rotation, a tubular member, a plurality of shelves, and a plurality of dividers. The tubular member is positioned along the axis of rotation and within the cargo volume of the housing. The tubular member defines one or more slots aligned with the axis of rotation. The shelves each define one or more engagement features that are each shaped to engage with a corresponding slot of the tubular member. A radially extending space is defined between a pair of shelves positioned directly adjacent to one another. The dividers that are each secured within a corresponding radially extending space when the storage container is in the locked position. Each of the shelves is configured to slide along the corresponding slot of the tubular member to adjust a volume the individual compartments.

A computer-implemented method for reducing spot welds in a parameterized workpiece model includes generating a new design space (DS) from an original spot weld DS. The new DS includes a plurality of spot weld locations from the parameterized workpiece model with the original spot weld DS. The new DS is optimized to have a fewer number of spot weld locations than the original DS. The processor identifies a plurality of offending spot weld locations of the remaining spot weld locations in the new DS and a plurality of conforming spot weld locations of the remaining spot weld locations. The processor removes all but one optimized extension candidate from processor-selected groupings of welds while enforcing a minimum distance requirement. The processor outputs an inter-distance constrained parameterized workpiece model with an optimized extension candidate in each of the plurality of extended DSs to an operatively connected output processor.
