EOS offered in 2007 to further investigate design solutions for e-manufacturing and publish results
— Technology know how is important for growing success
— Tolerances for e-Manufacturing
— Data Interface CAD – STL
— Need to define a data structure to be able to access many and complex information
— Hands on workshop from existing solution via functional abstraction to new solutions

Result: Small drill diameter probably need a
design offset – further investigation necessary

We discussed customer needs regarding Design for e-Manufacturing at the Design Inofshop 2007
— Need for more detailed Material Properties•UV degredation over time•Dynamic stress behaviour
— Minimal Wall Thickness & Repeatability
— Functional Elements•Bearings•Springs
— Know How Exchange•Best practice•EOS web page
Major discussion results

Design Rules allow the designer to take advantage of technology potentials and make him aware of
technology limits at the design stage already

Complex Design- and Technology Data need a well defined data structure
— Development of a Data Structure for e-Manufacturing Design Rules based on the Re-Design of an existing Sailing Boat Clamp

Redesign, empirical data survey & data structure investigation enabled the data structure description
— Target Definition
— Re-Design•Force & stress calculation•Design, production & tests
— Structure Definition•Analysis of design and design process•Analysis results & classification•Investigation existing data structures & creation of variations
— Application•Judgement and selection•Structure layout•Testing the prototype
Major steps

The choosen part fulfills several functions – ideal to practice functional integration

Several design variations were created – still looking similar to the original
Design Variations 0 to 7

Page 11EOS IUM 2008 · Design for e-Manufacturing · Joachim Göbner
Design Variation No. 8 shows a completely different design approach
— What initiated the completely new design approach?

The abstraction of the application to basic functions helps to find new solutions

— The basic catalog enables the designer to:
• quickly see whether solutions exist
• Access the solution• Find additional relations

The Design Catalog supplies technology information to the designer
— The Design Catalog enables the Designer to create new designs, aiming on his special design targets

— The Element Catalog enables the Designer to pick existing elements and modify them according to his needs

— A direct interface to CAD would be of additional advantage to the Designer

Next steps shall create the first catalog ready to use for designers
— IT programming of the and access to the database
— Fill the structure with existing Design Rules, Elements …•Do you have additional info, you want to share?
— Make the first version available and gather feedback•EOS web page?
— Collect feedback from you•What software do you prefer?•How to make the first version available?•Who would like to supply active feedback?•Prioritization of further Design Rules, Elements … (see list)
Outlook next steps
