Smart Trolley System Design: Preliminary and Detailed Design Process

This report provides a comprehensive analysis of the design process for a smart trolley system intended for use in supermarkets. It begins with an introduction to the concept, highlighting the shortcomings of traditional trolleys and the advantages of implementing a smart trolley system, such as reduced queuing times and enhanced customer control over purchases. The report then delves into the preliminary design and development phase, covering system functional analysis, synthesis and allocation of design criteria, and system and subsystem analysis. It further explores the detailed design and development, including system and product design, system and product model development, and system prototype testing and evaluation. The report also discusses system testing methodologies, such as unit testing, functional testing, and integration testing, along with simulation evaluation using Proteus Software. Finally, the evaluation section assesses the smart trolley system's performance, focusing on its ability to enhance the shopping experience through features like barcode scanning, POS system integration, and electronic payment options.
