Design for e-Manufacturing

Source: EOS GmbH / Masterthesis R. Hänsch


Review Infoshop IUM 2007


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

Headlines Infoshop Design for e-Manufacturing IUM 2007


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

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

Master Thesis Title



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

The original part on the boat



Several design variations were created – still looking similar to the original

Design Variations 0 to 7



Design Variation No. 8 shows a completely different design approach

— What initiated the completely new design approach?

Design Variation No. 8



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

Functional analysis chart of the clamp



Investigating existing structures enabled the data structure definition

Different structures



The Basic catalog supplies predefined solutions to the designer

— 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

Design Catalog



The Element Catalog supplies ready to use solutions to the designer

Element Catalog


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


The roller is one example how the Element Catalog will look like


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


How to use the Catalog & Next Steps


The Basic Catalog provides easy access to technology data, elements and correlations




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
