Kesan Penggunaan CAD3D Sebagai Medium Penjanaan Idea Inovasi Berbanding Lakaran Tangan.

Abstract

The use of 3D CAD software in product design engineering field is widely used due to its functionality and features are ease to user compare to traditional 2D CAD software for designing process. Unfortunately, the use of 3D CAD as a medium of idea generation technique at conceptual design stage is still under debating among the scholars where the method of hand sketch dominated longer as a medium of effective idea generation at the conceptual level. In this study, the effectiveness of using 3D CAD software versus hand sketch in generating an innovative ideas at the conceptual design process has been experimentally analysed. A quasi-experimental study using pre-test and post-test control group design method was conducted on manufacturing technology programme students, at Community Colleges, Ministry of Education Malaysia that took product design course by using 3D CAD software. The population consists of 106 students at four Community Colleges offered Manufacturing Technology Certificates where the samples consisted with 41 students for the treatment group and 34 students for the comparison group. The treatment group generated ideas using 3D CAD software while the comparison group used the traditional hand sketch method for ideas generation. ANOVA tests were used to determine a significant effect on the generation of novelty ideas, variety ideas and quality ideas. The findings showed that there is a significant difference in the ability to generate ideas using 3D CAD compared to traditional methods among mechanical engineering students. As a conclusion, the use of 3D CAD software as an idea-generation medium is much better in enhancing student’s achievement to produce innovative designed product compared to the traditional hand sketch method.
