Design improvement of a product with variable curvature based on TRIZ

Research output: Contribution to journalArticlepeer-review


In this work, a new design for mobiles proposes a flexible display that can be switched between flat and curved surfaces. After a few unsuccessful attempts, a noble conversion scheme between the two configurations was obtained after application of the TRIZ contradiction analysis. For physical embodiment of flat display effects of design parameters are investigated experimentally using the Taguchi method and response surface methodology. It is suggested that a finite element model might be useful for future applications after proper experimental validation.
