Konferensbidrag (refereegranskat)abstract
- Platform design has been firmly established in the automotive industry as a strategy to provide wider product variety while maintaining cost effective production. But this strategy can struggle to keep up with the pace and nature of emerging technologies. This paper reviews the existing approaches to modelling product platforms, and showcases the challenges at OEMs introducing new technological innovations in their platforms. A gap is identified in the methods to assess the ability of existing platforms to integrate new technologies whenever they become available.

THE KARAKURI CARD DECK: CO-DESIGNING INDUSTRIAL IOT CONCEPTUAL SOLUTIONS
- 2020
-
Ingår i: Proceedings of INTERNATIONAL DESIGN CONFERENCE – DESIGN 2020. - : Cambridge University Press (CUP). - 2633-7762. ; 1, s. 807-816
-
Konferensbidrag (refereegranskat)abstract
- Novel IoT market solutions and research promise IoT modules that do not require programming or electrical setup, yet shop floor personnel need to face problem solving activities to create technical solutions. This paper introduces the Karakuri card deck and presents a case study composed of four workshop sessions in four manufacturing settings, where shop floor personnel tested the cards as a means of ideating and presenting conceptual IoT solutions in the form of diagrams. The results indicate the validity of the proposed conceptual solutions and suggest prototyping as a next step.

Supporting Additive Manufacturing Technology Development through Constraint Modelling in Early Conceptual Design: A Satellite Propulsion Case Study
- 2020
-
Ingår i: Proceedings of the Design Society: DESIGN Conference. - : Cambridge University Press (CUP). - 2633-7762. ; 1, s. 817-826

Konferensbidrag (refereegranskat)abstract
- Function and constraints modelling are implemented to design two gridded ion thrusters for additive manufacturing (AM). One concept takes advantage of AM design freedom, disregarding AM limitations and is not feasible. The other concept considers AM limitations and is manufacturable and feasible. Constraints modelling highlights AM capabilities that can be improved, showing where future investment is needed. Constraints representation can also support the creation of technology development roadmaps able to identify areas of AM technologies that must be improved.

Calculating target thresholds for the margin value method using computational tools
- 2020
-
Ingår i: Proceedings of the Design Society: DESIGN Conference. - : Cambridge University Press (CUP). - 2633-7762. ; 1
-
Konferensbidrag (refereegranskat)abstract
- Overspecification or excess margin in a design can enhance its ability to absorb changes and uncertainty, but also deteriorates performance criteria such as weight and cost. This paper shows how the Margin Value Method (article in review) can be applied in conjunction with CAE tools such as FEA to quantify excess margin where a design is too complex for algebraic analysis. This new application context for the MVM is illustrated using a case study of a flange coupling design, in which topology optimisation is used within the MVM to identify opportunities for design improvement.

Towards realistic numerical modelling of thin strut-based 3D-printed structures
- 2023
-
Ingår i: Proceedings of the International Conference on Engineering Design (ICED23). 24-28 JULY 2023, Bordeaux, France. - 2633-7762. ; 3, s. 3591-3600

Konferensbidrag (refereegranskat)abstract
- The as-built geometry and material properties of parts manufactured using Additive Manufacturing (AM) can differ significantly from the as-designed model and base material properties. These differences can be more pronounced in thin strut-like features (e.g., in a lattice structure), making it essential to incorporate them when designing for AM and predicting their structural behaviour. Therefore, the aim of this study is to develop a numerical model with realistic characteristics based on a thin strut-based test artefact and to use it accurately for estimating its compressive strength. Experiments on test samples produced by selective laser sintering in PA 1101, are used to calculate geometrical deviations, Young's modulus, and yield strength, which are used to calibrate the numerical model. The experimental and numerical results show that the numerical model incorporating geometrical and material deviations can accurately predict the peak load and the force-displacement behaviour. The main contributions of this paper include the design of the test artefact, the average geometrical deviation of the struts, the measured material data, and the developed numerical model.

VR for ASSEMBLY TASKS in the MANUFACTURING INDUSTRY - INTERACTION and BEHAVIOUR
- 2020
-
Ingår i: Proceedings of the Design Society. - : Cambridge University Press. - 2633-7762. ; , s. 1697-1706
-
Konferensbidrag (refereegranskat)abstract
- A testbed was developed aiming to contribute to further knowledge on what is required from a VR application in order to be useful for planning of assembly tasks. In a pilot study the testbed was tested on students. The focus of the study was to explore the users' behaviour, and to gain a better understanding of their experience using VR. The students experienced a gap between the real world and VR, which confirms theories that VR is not a copy or twin of an object or environment.

YOU NEED TO FOCUS TO VALIDATE
- 2020
-
Ingår i: Proceedings of the Design Society: DESIGN Conference. - : Cambridge University Press (CUP). - 2633-7762. ; 1, s. 31-40
-
Konferensbidrag (refereegranskat)abstract
- Many research students find challenges when validating their research. Especially when they have expectations to contribute to both practice and the research body of knowledge. This paper argues that a key to successful validation of design research lies in the ability to focus on what to validate in advance of how to validate. The paper provide a set of guidelines to support a discussion on how to converge to a claim that actually can be validated. The paper reports on experiences from PhD level course on validation in design research.

Lessons learned from the application of enhanced Function-Means modelling
- 2020
-
Ingår i: Proceedings of the Design Society: DESIGN Conference. - : Cambridge University Press (CUP). - 2633-7762. ; 1, s. 1325-1334
-
Konferensbidrag (refereegranskat)abstract
- Although well researched and praised in academic publications, function modelling (FM) does not have gained much traction in industrial application. To investigate into possible reasons for this, this publication researches literature of nine different projects where enhanced function-means modelling has been applied. The projects are analysed for their purpose of FM-use, applied benefits and discovered challenges of the FM approach. From this, the main challenges for FM application are the abstraction level of the modelling language as well as the lack of an interface to CAD modelling.

AN APPROACH FOR TOPOLOGY OPTIMIZATION-DRIVEN DESIGN FOR ADDITIVE MANUFACTURING
- 2020
-
Ingår i: Proceedings of the Design Society: DESIGN Conference. - : Cambridge University Press (CUP). - 2633-7762. ; 1, s. 325-334
-
Konferensbidrag (refereegranskat)abstract
- This paper describes an approach for designing lightweight components produced through additive manufacturing (AM). Lightweight design is often done through topology optimization (TO). However, the process of manually interpreting mesh-based and imprecise results from a TO into a geometry that fulfils all requirements is complex. To aid in this process, this paper suggest an approach based on combining overhang-constrained TO with lattice-based TO to automate complex tasks, retain parametric control, and to minimize manufacturing cost. The approach is validated through a benchmark part.
