Methodology to develop a geometric modeling process according to collaborative constraints

Abstract

A product design goes through a Digital Mock-Up which is based on the product geometric model. This latter has an important role in the design project whose exploitation mainly depends on how it has been established [1]. Furthermore, the growing competitive context hardly encourages firms to implement new working methods like collaborative engineering. However, its implementation in combination with product geometric data generates many problems in terms of project and data management. For this purpose, this article proposes a methodological solution to the problem at hand. Moreover the problem gets complicated as the project progresses. As a result, the detailed design phase becomes critical particularly in the face of this problem. Therefore, the current article focuses on this phase of the product design process through an example.

EZID: A new approach to hazard identification during the design process by analysing energy transfers

“…They use similar methods and design tools that generate intermediate design objects. These objects allow the designer to represent the system from the earliest stages of the design process and they serve as milestones for design activities and guarantee the maturity of design parameters [7][8][9]. Their processing allows making decisions regarding the following phases in the development of a product.…”

“…Their processing allows making decisions regarding the following phases in the development of a product. X. Godot [8] also established that the activity within each design phase could be summarised by the five following generic tasks: creation, dimensioning, representation, optimisation /evaluation and validation Therefore, proposing an approach that can be used by all machine designers requires that the intermediary objects [7] and design parameters are based on generic design tasks (cf. Fig.…”

Digital Human Modeling in the Development of Assistive Technologies for Elderly Users

“…The use of DHM in order to improve certain features of a system or product is not a new concept, various types of digital human models being used for over 35 years. Starting with the digital human model used to asses pilot reach requirements by Ryan and Springer, at Boeing Aircraft, in the late 1960s [9], DHM is nowadays widely implemented in Computer Aided Design (CAD) prototypes in order to test and further enhance the interaction of the considered environment or product with human subjects [10,11].…”
