Participation scope and requirements

This module consists of a lecture (2 course hours per week), practical tutorial (2 course hours per week), and a tutorial (1 course hour per week).

Students are recommended, but not required, to complete a basic internship in a metal-processing industrial plant as well as have knowledge of materials technology and production.

You can complete the module after one semester with a graded portfolio assessment, encompassing:

- Homework (several assignments)

- Written test

Registration for the current semester

Please use ISIS to register for the 2023 summer semester. All further information about the semester will also be posted there.

Please note that you must register for the tutorial via MOSES:

Beginning 01.10. - winter semester

Beginning 01.04. - summer semester


If you have any questions about the course or scheduling, please contact:

Aryan Ghomashi, M.Sc.

Be sure to include your matriculation number, degree program, and intended qualification (bachelor’s, master’s).

Formal questions about exams should be discussed with the Examination Office or the ombudsperson for exams.

Please discuss any technical questions with your tutor during the practical tutorial/tutorial or office hours. If you require further assistance, our research associate is happy to help you.

FAQs about KL 2

Examination registration

I missed the deadline to register for the exam. Can I still register?
No. All bachelor’s students must register via MOSES before completing the first exam component (1st design homework assignment). Pursuant to the examination regulations, it is not possible to register after the deadline.

I registered on time for the exam in QISPOS but can’t find my registration in the portal.
It is possible that an error occurred in MOSES. lease contact the MOSES team or the contact person for KL2.
Tip: Take a screenshot once you have registered.

Can I de-register from an exam?
You can de-register from an exam via MOSES any time before the deadline. It is no longer possible after the deadline has passed. Sick notes should be submitted to the Examination Office.

Test review

Will I really benefit from an test review?
Yes! Despite our best efforts, it is possible we made a mistake when grading your work. Test reviews also offer you an opportunity to learn from your own mistakes. However, we do not provide sample solutions. Exam reviews are generally scheduled shortly after grades have been published. All information will be posted in ISIS.

Module assessment

How is the module Engineering Design 2 assessed?

Exam-equivalent coursework and the written test are equally weighted when calculating the final grade.

  • Homework is worth 50 points. 
  • The test is also worth 50 points.

To successfully complete Engineering Design 2, you must earn at least half (50 points) of the total points available (consisting of the homework and test).

The module grade is calculated using the following key:

(All information is subject to change!)

Total pointsGrade
>= 504,0
>= 553,7
>= 603,3
>= 653,0
>= 702,7
>= 752,3
>= 802,0
>= 851,7
>= 901,3
>= 951,0

Repeat students and recognition of completed homework

Recognition of completed homework: I took this module within the last two semesters and passed the homework component but not the written test. Do I need to submit the homework again?

No! Points earned for homework remain valid for a maximum of two semesters (12 months) and can be transfered to the next semester.  However, please be aware of the following:

  • You do not need to register in Moses for the tutorium.
  • When submitting the first test of the current semester, the previous homework points earned will be forfeited

You are required to register in QISPOS each semester during the registration period! The same deadlines apply as for students taking the course for the first time.

Please note:

If you earned less than half of the total possible available, you have the option to complete the homework again. The following rules apply:

  • You must register for the tutorial in Moses. 
  • You must register for the exam in QISPOS/SAP.

However, a new exam registration in Moses is required every semester within the regular registration period! The registration deadlines apply as for 'first-time takers'.

There is a possibility to redo the homework one more time. The following rules apply:

  • Registration for the tutorial via Moses is required.
  • Registration for exams via Moses
  • When submitting the first test of the current semester, the previous homework points earned will be cancelled

The written test must be rewritten each semester and cannot be transferred from a former semester.

Recognition of completed homework: I took this module three or more semesters ago and passed the homework component but not the written test. Do I need to submit the homework again?

Unfortunately, yes.  Any points earned have expired and you must submit new homework for the module examination. You must register for the tutorial in Moses.

Second repeat examination (oral exam)


If you have any questions, please contact:

Prof. Dr.-Ing. Robert Liebich

Aryan Ghomashi, M.Sc.

Information about repeat exams in the academic chairs KM and MPM

You can choose your examiner in the Design Theory modules. Professors Göhlich, Meyer, and Liebich all offer exams.


  • Beginning summer semester 2018, the 2nd repeat exam for Design Theory is only possible with Professor Meyer.
  • The examiners for Engineering Design 1 (until winter semester 2017/18) and Design Theory 1 are Professors Meyer, Liebich, and Göhlich.
  • The examiners for Design Theory 2/Engineering Design 2 (old) are Professors Meyer, Liebich, and Göhlich.
  • The examiners for Design Theory 3/Engineering Design 3 (aold) are Professors Liebich and Göhlich.


For further information about exam dates with Professors Meyer and Göhlich, please contact their academic chairs.

Chair of Machinery System Design - Prof. Meyer

Chair of Methods for Product Development and Mechatronics - Prof. Göhlich

Exam dates with Professor Liebich

Exam dates are arranged upon request.

Please send an email to the administrative office together with the module information, your matriculation number, degree program, intended qualification, and degree semester.

Please also check with the exam team to find out which exam attempt you are in. Please enclose this information with your request.

Preparation for the oral exam


All topics covered in the lecture and tutorial are relevant to the exam. Because KL2 (and KL3) are a continuation of KL1 (KL2), basic knowledge of KL1 (KL2) is also necessary. For instance, you should be able to identify bearing types.


Specific literature is not recommended, as this depends on your individual knowledge level and each resource has its own strengths and weaknesses.

If you are having difficulty understanding any of the material, we recommend the following:

  • University textbooks (Dubbel, Niemann-Winter, Maschinenelemente - Schlecht,...)
  • University of applied sciences textbooks (Decker, Roloff/Matek,...)
  • Vocational school textbooks (vehicle engineering,...)

to gain a basic understanding.
Once you are familiar with a topic, you can proceed with more advanced literature.

Office hours

We recommend regularly attending office hours!

If you have questions about the exam content, please make use of Professor Liebich’s office hours.
You are also welcome to make use of our research associates’ office hours for help with technical questions.
