Makerthon #9

May, 21st 1:00pm until May, 23rd

48 Hours
3 Interdisciplinary Teams
1 Challenge

Take the chance to gain hands-on experience on product development based on the design thinking approach.
We are looking for passionate Makers who want to work together in interdisciplinary teams on a real-life challenge from the industry in the field of “(electric vehicle) battery safety”.

Get the challenge - find ideas - develop concepts and build a prototype - use your skills and motivation to beat the challenge!

The Makerthon takes place at the Schumpeter Laboratory for Innovation.


The Makerthon is the possibility to face a real challenge supported by leading industrial companies and the Institute of Innovation and Industrial Management.
Within 48 hours, makers have to
1 - understand the challenge
2 - detect the real problems
3 - generate ideas
4 - select the ideas
5 - realize prototypes and
6 - to tell the story, why the solution will change the business and our lifes!

Makerthon #3
Friday, May 17th 2019 until Sunday 19th

Makerthon #5: May, 28th 3 PM until May, 30th

Challenge: Re-purposing for new application areas / business fields for AVL Stingray™

Key Facts AVL
  • Leading R&D expert in the
    areas of Automotive
    Powertrains, Drivetrain
    Solutions, Simulation &

  • > 11.000 employees

  • Fields of Expertise:
    • Testing Solutions
    • Simulation Technologies
    • ADAS and Autonomous Driving
    • Battery
    • Calibration
    • Controls and Electronics
    • E-Drive
    • Engineering Services

Situation / Object

Rising number of EVs in all areas leads to…

  • Increasing risk of thermal runaway for testbed operators / fire fighting personnel / workshops / warehouses / ferries / heavy duty / homes & co.

  • EV HV-batteries are very hard to control; Common methods are neither effective nor efficient

  • AVL has developed HV-battery fire suppression systems to control thermal runaways

  • New solutions for new application areas (ongoing electrification) are wanted / sought for
    • Bus / Trucks / Trains
    • Heavy duty / Forklifts
    • Ships / Ferries / …
Tasks / Objectives

Analyze at least one electrified vehicle / machine / device and develop a physical concept / prototype how AVL Stingray™ can be re-purposed / adapted or implemented / integrated to suppress a potential battery fire

  • Where is the battery located / what needs to be considered (e.g., enclosure thickness, battery setup, location)?

  • How can penetration units be applied /attached to the battery (integrated)?

  • Local storage of extinguishing media needed / possible? Where can it be stored (amount)?

  • Ideas for improvement of the working principle / set-up / re-purposing of AVL Stingray™?



Challenge 1

Key Facts ELIN Motoren
  • ELIN Motoren as part of Voith group is a global supplier for rotating electrical machines and life-cycle solutions
  • More than 120 years of experience in developing and producing rotating electrical machines
  • Business fields:
    • Wind Energy
    • Tunneling / Mining
    • Power Plants
    • Oil & Gas
    • Marine
  • Power range of machines beginning with 60 [kW] up to 50 [MW]
Situation / Object

Permanent magnet rotor design:

  • Rotor-skewing is possible for rotor-topologies with surface permanent magnets (discrete skewing).
  • Rotor skewing with buried magnets is not possible. This is bypassed by skewing the stator instead of the rotor.
Task / Objectives:
  • Find a method for rotor-skewing with buried permanent magnets in the case of the  segmented and non-segmented rotor-topology.
  • Pay special attention to:
    • Torque transmission
    • Feasibility of the manufacturing process

Challenge 2

Key Facts PAYER Medical
  • Leading and worldwide acting OEM/ODM Personal Care- and Grooming Products supplier

  • Located in St. Bartholomä near Graz

  • More than 75 years of experience in their business field

  • Facilities in Austria (HQ), Hungary and China with
    1000+ employees

  • Supplier to A-Brands like Braun, Philips, Wahl etc.

Situation / Object
  • Beardtrimmer and hairclipper products need a stiffer and more precise comb system.
  • Systems on the market are realized with cheap looking  plastic attachment combs
  • Fragile
  • No precise setting (cutting length)
  • Due to the design of the plastic mould the parting line is a problem (burr with e.g. skretches on skin)
Task / Objectives:
  • Search for alternative solutions to plastic attachement combs
  • Requirements:
    • High Quality appearance
      (weight, cold touch, stiff execution and confidence in using)
    • Easy to change and easy adjustment
    • Ready to have also 0,2 [mm] steps
    • Competitive production costs compared to plastic comb
