Abstract
In early phases of product development, uncertainty may be treated by a set-based design method relying on so-called solution spaces. In this approach, all relevant system requirements are used to produce interval-type component requirements that are sufficient for reaching the overall design goal while allowing for design flexibility. Unfortunately, only inequality-type requirements on the system level can be treated. This paper proposes several extensions to incorporate equality-based requirements into the framework and applies one projection technique to the design of a automotive tailgate.
