20ME43P- PRODUCT DESIGN AND DEVELOPMENT
20ME43P- PRODUCT DESIGN AND DEVELOPMENT
The design department of an industry is a key employment area for diploma engineers. Fundamental knowledge of Strength of Materials, Engineering Materials, and Computer-Aided Design and Drafting is crucial to meet the job requirements in this sector. To prepare students for this field, they must be equipped with the skills to design simple machine elements, understand procedures involved in product development, and have a foundational grasp of designing components such as shafts, springs, and couplings. Additionally, familiarity with codes, norms, standards, and guidelines for selecting appropriate materials is essential. Diploma engineers must also be proficient in reading and interpreting drawings, as well as preparing drawings of machine parts. This course aims to develop students' analytical abilities to solve basic engineering design problems using standard procedures. It emphasizes providing practical learning experiences that enable students to apply fundamental principles to design solutions for real-world problems, thereby developing the necessary skills and competencies.
