The Projections of Planes model proved to be highly beneficial for students. By first demonstrating the model and thoroughly explaining the problem, students could visualize different lengths and views, such as true and apparent. This approach significantly enhanced their learning efficiency. As a result, students were observed to solve complex problems involving various 2D shapes with greater ease.
Every student learning Engineering Drawing must understand the First and Third Angle Methods of Projection. However, it has been observed that majority of the students remain confused and unaware of these concepts by the time they reach their final year placements. The model I developed has been instrumental in helping students thoroughly grasp the First and Third Angle Methods of Projection. It also clarifies why the Second and Fourth Angle Methods of Projection are not used.
This model developed by me is highly effective in clarifying every concept related to Orthographic and Isometric Projections using the First Angle Method of Projection. It provides a comprehensive understanding of the Vertical Plane, Horizontal Plane, Profile Plane, reference axes, as well as the Front View, Top View, and Side Views.
Different Models for comprehensive understanding of Orthographic and Isometric Projections
Basic Mechanical Engineering Lab
Involved in procurement of following models for lab development,
Cut section of 4 stroke 4 cylinder I. C. engine
Motor operated types of Gears
Motor operated different Mechanisms
Assembly and disassembly model of 4 stroke 4 cylinder I. C. engine
Cut section of Differential gear box
Apart form this different models of mechanisms and basic elements were made
Experiential Learning Activity: Design for Assembly, Disassembly and Serviceability
To enhance practical understanding of Design for Assembly (DFA), Design for Disassembly (DFD), Serviceability, and Human Factors in Design, students will perform a hands-on activity using pedestal/table fans of different brands. ⚙️🔧
In this activity, students will:
✅ Select two different fan models for comparison.
✅ Perform complete assembly and disassembly of both fans.
✅ Observe and record design features such as type of fasteners, modular parts, ease of handling, wiring arrangement, safety provisions, and maintenance accessibility.
✅ Evaluate human factor considerations like ergonomics, safety during assembly, user comfort, and ease of servicing.
✅ Compare both products based on:
Number of parts
Assembly time
Tools required
Ease of maintenance and repair
Safety and user-friendliness
Design standardization and modularity
📊 Students will then prepare a structured report explaining:
Which Design for assembly/disassembly principles are applied
How serviceability is ensured
What human-centered design features are incorporated
Which fan design is better and why, supported by observations and logical justification
🎯 This activity provides excellent experiential learning, helping students connect theoretical design principles with real product analysis, improving their skills in product evaluation, reverse engineering, and practical design thinking.
