Objective: The purpose of this study is to suggest design guidelines for the door opening of an automobile based on the ease of ingress and egress. This study will show how the vehicle's design guidelines are derived, especially through the example of foot clearance among many design elements of the automobile. Background: Recently, as well as the performance of the automobile, the ergonomic design for its appearance and convenience has become important to consumers. However, compared to the developed countries, there are only a few ergonomic researches and applications of the automobile in Korea. Method: Twelve participants evaluated the degree of discomfort for two levels of foot clearance. Results: Binary logistic regression analysis was performed between the probability of the discomfort and the ratio of the foot clearance and the foot length. Conclusion: A specific foot clearance could be derived according to a length of foot in an acceptable discomfort probability. Application: The results can be utilized when designing the foot clearance of the automobiles. Thus, through the evaluation of ease of ingress and egress, design guidelines for other elements can also be suggested.

Discovering users demands is essential for successfully developing a service or product. Users perception and demand play a critical role in developing the Smart Design Platform that is a platform service helping thermal energy-intensive industrial facilities to more efficiently and easily design their products. This study investigates a process and analysis of perception and demands from the two viewpoints: technology providers and consumers who are targeted users of the Smart Design Platform. A preliminary online survey gained a total of 630 potential users’ feedbacks. It will demonstrate sufficient demands for the Smart Design Platform. For an advanced analysis of users’ demands, additional interviews will be conducted with technology providers and consumers.

One of the most interesting areas in the automotive industry is lightweight. Among the many lightweight components, the back beam, which was originally made of steel, was developed as an injection type composite back beam using CFT and TPO. In order to develop the model, the collision analysis and the actual collision test were performed using CAE. Comparing the two results showed similarity of the data and the CAE model needs to be supplemented. The section moment was used to set the thickness with the same moment as the cross section containing the gradient. The results of the collision analysis again with the newly set section are similar to those of the test. It is confirmed that the method using the moment of the section reduces the actual test and error.
