1. Project Background & Context
Current industrial trends…
• Globalisation
Computer Supported Collaborative Work (CSCW)
• National
• Branch
• Corporate
• Professional
Differing cultures “ Culture is the collective ‘programming’ of the mind that distinguishes one group of people from another ” [Hofstede, 91]
[Ulijn & Weggman, 01]
• Increasing product complexity
Steven Gowers - Final Year Research Project
Development of CoDISSCollaborative Data and Information Sharing System
Global Design Experiment
Collaborative design between Elec and Mech engineers
Proposed development of CoDISS II and Virtual Project Platform (VP2)

1. Project Background & Context
2. Project Aims
Main areas of the project
1. A general ‘ cultural ’ study A study of two differing professional cultures
2. A specific ‘ optimisation ’ study Integrated optimisation-dimensioning of electromagnetic products
Steven Gowers - Final Year Research Project
Study the product design processes and the exchanges of information in the domains of mechanical and electrical engineering. Suggest new approaches to global design and specify and start to develop a support tool for collaboration.
3. A general ‘cultural’ study
Electromagnetic product development is a segregated activity, with designers adopting an ‘over the wall’ approach.
What are the problems?
A general study into Mechanical and Electrical engineering
• Specialist knowledge
Scientific principles, experiences, contacts

3. A general ‘cultural’ study
Defining Requirements
Conceptual design
Embodiment design
Detailed design
Choice of structure
Optimisation, dimensioning and development of structure
Simulation and further development
Defining Requirements
A specific approach…Key observations
Little support for upstream stages
Very analytical
‘Overall’ approach
Lots of emphasis placed on optimisation
(Optimisation is a means of dimensioning an initial structure)

4. A specific ‘optimisation’ study
Steven Gowers - Final Year Research Project
Global Design experiment last year...
A segregated approach
• Spring selected by mechanical engineers in ‘isolation’
• Very iterative
• Clear deficiencies in the approach
A significant example…
4. A specific ‘optimisation’ study
A more integrated approach...
• Development of an analytical model for the spring
• Create an ‘overall’ analytical model
• Dimension the spring whilst at the same time optimising the overall structure

5. Collaborative Optimisation
Steven Gowers - Final Year Research Project
Collaborative Optimisation - What advantages can it offer ?
• Effective and efficient way of carrying out coupled problems, in keeping with the ‘overall’ approach
• Optimisation engine carries out iterative dimensioning process
• Additional gains if products become more complex or if companies develop variants
• Central collaborative platform during embodiment stages
• Quickly identify if a common solution does not exist
Steven Gowers - Final Year Research Project
6. Conclusions
• Specific study into two differing professional cultures
• Integrated optimisation approaches
• Development of a global communication platform supporting optimisation
Development of a framework supporting collaborative global design based on a study into differing professional cultures

A specific ‘optimisation’ study
A significant example - the electromagnetic plunger
Resultant force due to magnet
Current charges bobbin
Movement of central core governed mainly by the spring
