Luggage Carrier Mechanism - Mechanical

 Mobility is one of the important and basic needs of human. Design, Features and aesthetics of a vehicle has always played an important role in a customer's buying decision. In this scenario the increase in transportation and the facilities that are providing by the automobile industries respect to the transportation system in cars will play an important role. For transporting, the luggage weight is one of the main aspects considered by the users. So while loading and unloading the luggage in to the boot space of a car is becoming more difficult. A system is designed in the boot space of a car to reduce the ergonomic problems; easy way of loading the luggage to the elderly people, taxi drivers and with less time more luggage’s is shifted.

Literature survey has been done to identify the existing processes and methods of for luggage loading and unloading systems. For knowing what exactly required by the customers, user survey was done to identify the problems faced during loading and unloading of the luggage from the boot space of a car. After analyzing the customer survey results, concepts were generated and rendered according to the customer requirements. Using weighted ranking method one concept that most suits to the problem was selected. After finalizing the concept, digital model was generated. CATIA V5 software was used for geometrical modelling.

The selected concept consists of a box inside the trunk which will come outside and helps the users to keep the luggage easily. It’s a simple mechanism consists of a two links on both sides and a box. Rotational motion is applied to one of the link i.e., joint one which in turn results in translation motion of the box. Once the box comes outside the user can easily keep the luggage. This is how the mechanism works. Finally the model of the mechanism was tested in Automated Dynamic Analysis of Mechanical Systems and forces on each links are obtained which can be used for further analysis.
