Preliminary Resource-based Estimates Combining Artificial Intelligence Approaches and Traditional Techniques
(2016)Procedia Engineering ~ Selected papers from Creative Construction Conference 2016The fate of many construction projects is determined using preliminary project cost estimates. These estimates play a key role during the conceptual phase of projects; as in many cases they are the primary element used to decide their viability. The lack of information and the high levels of uncertainty during the conceptual phase, make it infeasible to have reliable building information models that could be used to generate quantity ...Conference Paper -
Considering Part Orientation in Design for Additive Manufacturing
(2016)Procedia CIRP ~ 26th CIRP Design ConferenceAdditive Manufacturing (AM) is established not only in prototyping, but also in serial production of end-use products. To use the full potential of the production technology the restrictions of current additive manufacturing processes (like support structures in Selective Laser Melting) must be considered in the design process. Especially the compliance with design rules from early design stages on is important in AM serial production, ...Conference Paper -
Design Library Solution Patterns in SysML for Concept Design and Simulation
(2016)Procedia CIRP ~ 26th CIRP Design ConferenceObject-oriented models in the Systems Modeling Language (SysML) are developed in this paper to support the concept development phase within engineering design. Generic libraries in SysML for functions, according to the functional basis, and structural components, are presented in previous work by the authors. This paper extends this work and proposes the use of multi-solution patterns in SysML that combine a new behavior simulation library ...Conference Paper -
Design Guidelines for Additive Manufactured Snap-Fit Joints
(2016)Procedia CIRP ~ 26th CIRP Design ConferenceSnap-fit joints are one of the cheapest and fastest connectors available. However, due to geometrical complexity of the joints and the limitations of injection molding, they are used almost exclusively in large-scale manufactured products. Additive manufacturing offers the possibility to create end-user products in small and medium numbers with almost unlimited design complexity. This clears the way for new solutions using snap-fit joints ...Conference Paper -
Iteration-based Performance Measurement in the Fuzzy Front End of PDPs
(2016)Procedia CIRP ~ 26th CIRP Design ConferenceIterations are an inherent phenomenon in product development processes (PDPs), especially in its fuzzy front end (FFE), and a crucial concept in coached ideation workshops. Small- and Medium-sized Enterprises (SMEs) perceive such workshops as promising means for developing new products and enhancing their innovation capability. This raises the research questions of (1) “how to measure the performance of PDPs in its FFE?” and (2) “Which ...Conference Paper -
Multilevel Design Education for Innovation Competencies
(2016)Procedia CIRP ~ 26th CIRP Design ConferenceThe competencies to manage an engineering project, work in and lead a team are demanded from a graduate of a higher engineering education. A design education model, consisting of of two linked courses, is presented that allows students to learn key engineering and social competencies by experiencing real situations. During the course “Innovation Project” (IP) approx. 450 freshman solve a development task in a team (creating a mechatronic ...Conference Paper -
Combining Additive Manufacturing with Advanced Composites for Highly Integrated Robotic Structures
(2016)Procedia CIRP ~ 26th CIRP Design ConferenceThe combination of additive manufacturing with advanced composites offers potentials in the development of highly integrated lightweight structures. This paper investigates a novel manufacturing process route where binder jetting is used to produce a water soluble sand core for hand layup of autoclave prepreg composites. The novel approach is applied to a hollow high performance robotic part demonstrating the following two design potentials: ...Conference Paper
