“…These are active areas of research [7] and still poorly addressed by current industrial tools [38]. Although some success has been reported using semi-automated tools [38][39][40][41], the task of capturing design intent cannot be completely automated [42], and thus requires designers to be actively involved throughout the entire process.…”

“…After an exhaustive literature review to identify common elements, authors Iyer and Mills [7] proposed their own definition, which is generally widely accepted: "Design intent contained in legacy CAD is the insight into the design variables (design objectives, constraints, alternatives, evolution, guidelines, manufacturing instructions and standards) implicit in the structural, semantic and practical relationships between the geometric, material, dimensional and textual entities present in the CAD representation." [7].The importance of design intent and the advantages of an explicit representation were summarized by Pena-Mora et al [37]:…”

Revista:Computer-Aided Design Versión / Versió: Preprint Cita bibliográfica / Cita bibliogràfica (ISO 690):CAMBA, Jorge, et al. Extended 3D annotations as a new mechanism to explicitly communicate geometric design intent and increase CAD model reusability. ComputerAided Design, 2014, vol. 57, p. 61-73 AbstractA successful implementation of the Model-Based Enterprise concept (MBE) requires maximizing the potential benefits of annotated 3D models. The foundations of the MBE model are established by digital product definition data practices, which are currently regulated by standards such as ASME Y14. 41-2003 and ISO 16792:2006. At the center of the MBE concept is the notion of CAD model reusability, which relies on the idea that 3D CAD models can be reused both throughout the entire product lifecycle and as a starting point for future development of new products. In this context, a critical aspect of CAD model reuse is the proper identification and understanding of the geometric design intent that is usually expressed implicitly within the CAD model.In this work, we present a method to communicate geometric design intent explicitly by overloading and extending the scope of the current annotation instruments available in the MBE approach. We propose a new broader type of model annotation that we call "extended annotation," where design information is represented both internally within the 3D model and externally, on a separate repository. This structure naturally demands additional mechanisms to support the interaction of users with the information. In order to manage the information stored in these extended annotations effectively, we implemented an annotation manager that automatically synchronizes the dual representation of the annotations. To reduce the visual clutter in the 3D model, the software provides powerful filtering, editing, and visualization capabilities, giving users complete control of the information stored in the model. Finally, a study was conducted with 60 participants to evaluate the performance of the proposed model and the usability of the annotation manager. Results show a statistically significant benefit of using the extended annotation system, suggesting the use of this model as a valuable approach to improve design intent communication.

“…The intent differs from the functionality in that the intent justifies a design decision whereas the functionality just tells what the design does'' (Henderson 1993). It is the core rationale underlying how CAD models and 2D technical drawings should be constructed to communicate functional meaning of a design (Iyer and Mills 2006;Li et al 2010;Mandorli et al 2016). The design intent behind the cases in this paper is not known but it is assumed that the designer intended novelty by submitting a patent.…”

Design for invention: annotation of functional geometry interaction for representing novel working principles

et al. 2017

In some mechanical engineering devices the novelty or inventive step of a patented design relies heavily upon how geometric features contribute to device functions. Communicating the functional interactions between geometric features in existing patented designs may increase a designer's awareness of the prior art and thereby avoid conflict with their emerging design. This paper shows how functional representations of geometry interactions can be developed from patent claims to produce novel semantic graphical and text annotations of patent drawings. The approach provides a quick and accurate means for the designer to understand the patent that is well suited to the designer's natural way of understanding the device. Through several example application cases we show the application of a detailed representation of functional geometry interactions that captures the working principle of familiar mechanical engineering devices described in patents. A computer tool that is being developed to assist the designer to understand prior art is also described.

“…In a survey conducted by Iyer and Mills [2006], common elements were identified in a number of definitions and interpretations of design intent. This information was used by them to provide a comprehensive definition in the domain of 2D CAD: "Design intent contained in legacy CAD is the insight into the design variables (design objectives, constraints, alternatives, evolution, guidelines, manufacturing instructions and standards) implicit in the structural, semantic and practical relationships between the geometric, material, dimensional and textual entities present in the CAD representation."…”
