Abstract: A design for repair casting having a repairable ultra-large single-piece casting and a replacement part. The ultra-large single-piece casting includes a main body portion, at least one predefined replaceable portion integrally cast with the main body portion, and a cut-guide delineating the predefined replaceable portion from the main body portion. The cut-guide includes a continuous channel defined on an exterior surface of the single-piece casting. The cut-guide further includes a rib extending from a channel wall on the main body portion. A damaged replaceable portion is excisable from the main-body portion by cutting through the single-piece casting along the cut-guide. The excised damaged replaceable portion may be replaced with the replacement part, which has substantially the same geometry, dimensions, and mechanical properties as an undamaged replaceable portion. The replacement part may be joined to the main body portion by mechanical means or by welding.

Abstract: A method of repairing an ultra-large single-piece cast component of a vehicle body. The method includes the steps of locating a damaged portion of the cast component, determining an extent of the damaged portion of the ultra-large cast component, defining a cut-line sectioning off the damaged portion from an undamaged portion of the ultra-large cast component, cutting along the cut-line to excise the damaged portion from the undamaged portion of the ultra-large cast component, and joining a replacement piece to the undamaged portion of the ultra-large cast component. The replacement piece is fabricated based on the original manufacturer’s geometry and dimensional data of the excised damaged portion. The undamaged portion of the ultra-large cast component remains on the vehicle body during the repair.

Abstract: A container holder for a vehicle is disclosed. The container holder defines a central axis. The container holder includes an inner body defining an innermost surface, where the innermost surface of the container holder is shaped to receive a bottom portion of a container. The container holder also includes an iris mechanism at least partially surrounding the inner body. The iris mechanism includes a plurality of blades that expand inwardly towards the central axis of the container holder and exert a clamping force upon a container placed within the inner body of the container holder.
