  1. 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 Current Working Knowledge – (CWK-DPd) Design Product Knowledge Domain Knowledge – (DK-DPd) Product Lifecycle Knowledge Current Working Knowledge – (CWK-DPc) Design Process Knowledge Domain Knowledge – (DK-DPc) Supplementary Knowledge

  4. My research focus 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 Current Working Knowledge – (CWK-DPc) Current Working Knowledge – (CWK-DPc) Current Working Knowledge – (CWK-DPd) Current Working Knowledge – (CWK-DPd) Domain Knowledge – (DK-DPd) Domain Knowledge – (DK-DPc)

  5. Research aim and objectives • Research Aim • Research Objectives To couple product and design process knowledge evolution to support design development. • To identify the gaps in design knowledge research area • To obtain requirements from industry • To reveal coupling mechanism of product and design process • To reveal the phenomenon of dynamic evolution between the product and design process • To develop the coupling model of evolutionary artefact and design process knowledge • To evaluate the model

  6. Literature, Industry design process documents • UG & PG students design projects • Industry design practice Data source triangulation • Content analysis • Case study • Protocol study • Model development • Model evaluation Methods triangulation Theory triangulation Research methodology • Post-positivism • Triangulation • The reality is multiple, subjective, and mentally constructed by individuals • Design characteristics • Multiple perspectives

  7. Research design Airbus design practise & PG student project Documentation - Thesis* Evaluation: Refined Model* Design Problem* - Design knowledge Literature Review Design Product, Process Model Review Data source Knowledge Coupling Review Research Problem* - To explore design knowledge coupling Hypothesis - Evolutionary knowledge coupling model* Outcome Aim and Objectives Research Process Affect Line Airbus PLM training & UG Student Project * Checking and reflection are needed Industry interview & documents analysis

  9. Exploring: Coupling elements Coupling category Coupling mechanism Evolutionary triggers Coupling product and design process knowledge • Model----Model of process----Cognitive Model • Cognitive model: representation of how people perform some mental task or activity CWK-DPd1 CWK-DPc1 CWK-DPd2 CWK-DPc2 CWK-DPd(n-1) CWK-DPc(n-1) CWK-DPdn CWK-DPcn Interaction of Product & Process

  10. Coupling Mechanism (Initial exploration) Decision (I) (evolve DPc or DPd) Design Process Knowledge Design Product Knowledge Design process Design Product Design Specification Design Structure Design Behaviour Design Function Constraints Relations Time Schedule Design Activities Design Rationale Material (M) Energy (I)

  11. Work has been done • Literature review of design product knowledge and design process knowledge modelling • Product lifecycle knowledge collection through working along PLM • 4th and 5th 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

  13. Summary • Design knowledge • Research issues • Research objectives • Research methodology • Coupling model • Finished work • Future work
