Therefore at the developing design process, how to decrease the probable failure and increase the effect design of the product is an important process in the designing process. FMEA, fail mode and effective analysis, which is one of a common method to analysis and find out the fail mode of the product is to dig out the unobservable problem or hidden mistake at the design and manufacture process or before deliver the product, no matter what is a system, a design, a manufacture process, or a service. Traditional fail mode and effective analysis method focus on the analysis of severity, occurrence, and detection of the fail item and calculate the risk priority number of those fail items. When the risk priority number over the acceptance range, the brainstorming method and cause-effect diagram can create an improve strategies to decrease the severity and probability of the failure. But how does the improve strategies affect the other subsystem did not be considered. TRIZ, Teorija Rezhenija Izobretate Zadach, is a new method applying the contradiction matrix in the product developing and designing process. It can help the designer to recognize the aggravating of subsystem and afford a suitable method to the solver. TRIZ become more important solution in the enterprise. A major research in this paper is to use a combination methodology to analyze the failure problem of the product. First, the fail mode and effective analysis method is used to analysis the failure problem of the product, then sue the TRIZ method to analyses the correlative problem between the failure problem and the other subsystem.An example of tray improves in Chip on Glass process of the Thin Film Transistor-Liquid Crystal Display has been shown in this paper.
