Generic Description |
The discipline aims to provide students with knowledge about some important modern design theories and methodologies. |
|
|
To Know |
Notion about design activity and features. Differences between analytical and synthetic activities. The main stages of the engineering design process development. |
|
|
Notion about decision making problem. Basis of the Decision Matrix methodology. |
||
|
The use of an axiomatic approach in engineering design. Basis of the N.P. Suh’s Axiomatic Design. |
||
|
Solution generation. Notion about conflict or technical contradiction. Basis of the Theory of Inventive Problem Solving (TRIZ / TIPS). |
||
|
Notion about “The voice of the customer”. Basis of the Kano’s Model. |
||
|
The conversion of the customer attributes to the product’s engineering characteristics. Basis of the Quality Function Deployment (QFD). |
||
|
Notion about robustness. Basis of the Taguchi’s Robust Design. |
||
|
Basis of the Concurrent Engineering. |
||
|
Other new paradigms for product development. Basis of Design for X (DFX). |
||
|
To Make |
Build a Decision Matrix. Take a decision and draw up strategies based on analysis of results obtained from the Matrix. |
|
|
Apply the Axiomatic Design (AD) concepts of domains, hierarchy and mapping (zigzagging) to mechanical design problems. Use the AD First Axiom in the analysis of design solutions based on their independence. Apply the AD Second Axiom to compare and choice design solutions based on their information content. |
||
|
Use the TRIZ Substance - Field Analysis to identify problematic situations and their solution based on the standard solutions. Build a contradiction table and find possible solutions. |
||
|
Prepare Kano’s Model questionnaire. Build a table with questionnaire results treatment. Build a satisfaction/dissatisfaction diagram. Draw up strategies based on analysis of results obtained from the questionnaire. |
||
|
Build a QFD “House of Quality”. Draw up strategies based on the “House of Quality” analysis. |
||
|
Apply the Robust Design concepts to mechanical design problems. Seek the best control parameters values to reduce the quality parameters variation. |
||
|
Apply the Concurrent Engineering concepts to mechanical design problems. |
||
|
Apply the Design for X (DFX) concepts to mechanical design problems. |
||
|
Soft Skills |
Project management. |
|
|
Turning technology into business. |
||
|
Technology and global development. |
||
|
The knowledge of social and ethical implications of technology. |
||
|
Teamwork. |

Teaching method
The oral exposition is essentially the teaching method used, associated with sketches, schemes and resumes made by the teacher in the classroom blackboard. The video projector is also used in the classroom.
The teacher solves representative problems first to introduce the students to the problem strategies of resolution. Then some problems are presented and a time period is fixed to the resolution. The teacher will attend any doubts during this period. All problems are solved in the blackboars classroom and commented.
Evaluation method
The final classification will be determined by the the average of the grades of the four tests.
