Coupling product and design process knowledge evolution Student: Wenjuan Wang Supervisor: Alex Duffy CAD Centre, DMEM, University of Strathclyde
2
Overview Design knowledge Research issues Research objectives Research methodology Coupling product and design process knowledge Finished work Future work Summary
3
Knowledge involved during product lifecycle Design Product Knowledge Design Process Knowledge Domain Knowledge – (DK-DPd) Current Working Knowledge – (CWK-DPd) Domain Knowledge – (DK-DPc) Current Working Knowledge – (CWK-DPc) Product Lifecycle Knowledge Supplementary Knowledge
4
Research Issues How the change of current design product knowledge affect design process? & vice versa? What’s the coupling mechanism of CWK-DPd and CWK-DPc Domain Knowledge – (DK-DPd) Current Working Knowledge – (CWK-DPd) Domain Knowledge – (DK-DPc) Current Working Knowledge – (CWK-DPc) Current Working Knowledge – (CWK-DPd) Current Working Knowledge – (CWK-DPc) My research focus
5
Research aim and objectives Research Aim Research Objectives To couple product and design process knowledge evolution to support design development. TT o identify the gaps in design knowledge research area TT o obtain requirements from industry TT o reveal coupling mechanism of product and design process TT o reveal the phenomenon of dynamic evolution between the product and design process TT o develop the coupling model of evolutionary artefact and design process knowledge TT o evaluate the model
6
Research methodology Post-positivism Triangulation The reality is multiple, subjective, and mentally constructed by individuals Design characteristics Multiple perspectives Literature, Industry design process documents UG & PG students design projects Industry design practice Data source triangulation Model development Model evaluation Theory triangulation Content analysis Case study Protocol study Methods triangulation
7
Research design Research Process Affect Line Literature Review Airbus design practise & PG student project Outcome Research Problem* - To explore design knowledge coupling Design Product, Process Model Review Documentation - Thesis* Design Problem* - Design knowledge Hypothesis - Evolutionary knowledge coupling model* Evaluation: Refined Model* Airbus PLM training & UG Student Project Industry interview & documents analysis Data source Knowledge Coupling Review Aim and Objectives * Checking and reflection are needed

Coupling Mechanism (Initial exploration) Design process Design Process Knowledge Design Product Design Product Knowledge Decision (I) (evolve DPc or DPd) Material (M) Energy (I) Time Schedule Design Activities Design Rationale Design Specification Design Structure Design Behaviour Design Function Constraints Relations
11
Work has been done Literature review of design product knowledge and design process knowledge modelling Product lifecycle knowledge collection through working along PLM 4 th and 5 th year undergraduate students design projects recording
12
Future work To finish building the coupling model of product and design process based on student design projects and literature; To complete the coupling model by analysing current data To evaluate the model –To obtain and analyse protocol data of design process by working alongside experienced designers in Airbus –To obtain and analyse postgraduate students design process data To finish the thesis writing
