Design proposal of a double base for child restraint system for two children
Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
In this project the design of a double base for two child restraint seats (CRS) has been developed. The objective of this project is to facilitate the transportation of two children in the rear seats of a car, maximizing the space available in the rear of the car and providing a comfortable movement to the user when placing the CRS baskets into the car. Scientific articles have been analysed providing a reference of the strength limitations and ergonomics aspects of the users as well as misuse of current CRS. Also, ergonomics and safety issues have been studied through these articles in order to fulfil with the current regulations established by the EU standards and the regulation 44 of Economic Commission for Europe. A market research and survey investigations have been done in order to study the features of existing CRS designs, opinion and needs of habitual users. The employed methodology based on a divergent and convergent design process has been carried out through different methods such as Brainstorming, 6-3-5 Method and Dark Horse Prototype in which many ideas, concepts and proposals have been developed and explained. The results of this project are shown and explained through a virtual 3D CAD model with their respective renders, explanations and technical drawings. The use and material selection of the final design are presented as well as the results of an ergonomic study performed by test with a simple physical prototype of the final design. The main outcomes of this project are included in conclusion, discussions and future work sections.
