Shoulder Bushing Lip Redistributes Flange Load

The bushing is segmented into distinct functional zones: a thicker first portion that contacts the fillet radius for load redistribution, and a thinner second portion that accommodates the bolt. This segmentation allows each zone to perform its specific function optimally without requiring uniform thickness throughout the entire bushing.

The bushing exhibits non-uniform thickness distribution with the first portion being thicker than the second portion. This local quality variation concentrates material where load bearing is critical (at the fillet radius contact zone) while reducing material where it is less critical (at the bolt accommodation zone), thereby optimizing strength without proportionally increasing overall complexity.

The bushing is divided into functional segments with different thicknesses, allowing the design to be simpler overall while maintaining adequate strength in critical areas. The segmented approach avoids the need for uniformly thick designs that would increase complexity and cost throughout the entire component.

By concentrating material thickness locally at the first portion where load bearing is most critical, the design achieves sufficient strength without requiring uniform thickness increases throughout the entire bushing. This localized material placement maintains load bearing capacity while keeping the overall design simpler and more cost-effective.
