The goal of our project was to design and manufacture a inter-convertible table cum bed mechanism that takes up less space, is robust, has low cost and can be used for multiple purposes in homes, hostels, hotels and offices. This project stems works on the problems faced by people living in small apartments and tries to find a potential solution for the space problem by space optimization and therefore by implementing a sliding mechanism for an inter-convertible table-cum-bed mechanism. Arc welding is a commonly used joining process and has been used in joining the table top and the legs. The mechanism has been designed in a simple manner so that it is easy for the user to operate. The legs of the bed have been given a mechanism through which it is folded and gets locked between the supports inserted at the bottom of the table top. To facilitate an effective and successful design, a comprehensive list of customer requirements was transformed into quantitative engineering specifications. The critical requirements for the end product are as follows: robust, safe, affordable, be reconfigurable, and easy to operate. Throughout the design process, both the requirements and their corresponding specifications have been re-evaluated and redefined The design process in its entirety is detailed throughout this report, including methodology, procedures, analyses, and end results. A detailed description, including finalized CAD models of all components is provided as well. The design has evolved throughout the process and the current design is the result of intense engineering efforts and analysis.
