Mechanical Engineering Design Course

Lesson 1 • The Engineering Design Process

Covers the iterative design cycle from problem identification to solution validation. Anchors all subsequent design activities in a repeatable methodology.

Lesson 2 • Engineering Standards and Specifications

Explains how industry standards and product specifications guide design decisions. Learners learn to read and apply technical standards in design work.

Lesson 3 • Design Documentation Fundamentals

Teaches essential documentation practices including design logs and requirement sheets. Proper documentation supports traceability throughout the design lifecycle.

Lesson 1 • Dimensioning and Tolerancing

Covers proper dimensioning rules and geometric dimensioning and tolerancing (GD&T). Accurate tolerancing ensures parts are manufacturable and interchangeable.

Lesson 2 • Drawing Standards and Title Blocks

Covers drawing sheet formats, title block content, and revision control practices. Standardised drawings enable consistent interpretation across teams and suppliers.

Lesson 3 • Sectional and Detail Views

Introduces sectional cuts and detail views to expose internal geometry. These views clarify complex features that multiview drawings cannot fully convey.

Lesson 4 • Assembly Drawings and Bills of Materials

Explains how to create assembly drawings and structured bills of materials (BOMs). Learners link part drawings to assemblies for complete design packages.

Lesson 1 • Sustainability in Material Choice

Examines environmental impact, recyclability, and lifecycle considerations in material selection. Learners integrate sustainability metrics alongside performance criteria.

Lesson 2 • Metals, Polymers, and Composites

Surveys the major material families and their characteristic performance ranges. Learners match material families to application requirements efficiently.

Lesson 3 • Surface Treatments and Coatings

Covers surface engineering techniques that extend component life and performance. Learners select appropriate treatments to meet corrosion, wear, and aesthetic requirements.

Lesson 4 • Material Selection Methodology

Introduces systematic selection tools including performance indices and material charts. Learners rank candidate materials against weighted design criteria.

Lesson 1 • Design for Structural Reliability

Applies probabilistic thinking and safety factor selection to structural design decisions. Learners balance weight, cost, and reliability in component sizing.

Lesson 2 • Stress and Strain in Structural Members

Covers normal, shear, bending, and torsional stress distributions in common cross-sections. Learners calculate peak stresses and locate critical failure points.

Lesson 3 • Deflection and Stiffness Analysis

Teaches beam deflection methods and stiffness calculations for structural members. Deflection limits often govern design independently of strength requirements.

Lesson 4 • Fatigue and Failure Theories

Introduces fatigue life prediction and multiaxial failure criteria for ductile and brittle materials. Learners apply safety factors to achieve reliable designs under cyclic loading.

Lesson 1 • Shafts and Keys

Teaches shaft design for combined bending and torsion with keyway and spline connections. Proper shaft sizing ensures reliable power transmission without fatigue failure.

Lesson 2 • Gears and Power Transmission

Covers spur, helical, bevel, and worm gear geometry, rating, and selection. Learners design gear trains to achieve required speed ratios and torque capacities.

Lesson 3 • Fasteners and Joining Methods

Covers threaded fasteners, welds, adhesives, and press fits for structural joints. Learners select and size joining methods based on load type and assembly requirements.

Lesson 4 • Springs and Energy Storage Elements

Teaches helical compression, extension, and torsion spring design and selection. Springs are analysed for stress, deflection, and fatigue life in dynamic applications.

Lesson 1 • Surface Modelling Techniques

Introduces lofted, swept, and boundary surface creation for complex geometry. Surface modelling extends solid modelling capability for organic and aerodynamic shapes.

Lesson 2 • Assembly Modelling and Constraints

Covers mate and constraint application to build multi-part CAD assemblies. Learners verify fit, clearance, and motion in virtual assemblies before fabrication.

Lesson 3 • CAD Data Management and Collaboration

Covers file formats, PDM systems, and collaborative CAD workflows across teams. Proper data management prevents version conflicts and protects design integrity.

Lesson 4 • Drawing Generation from 3D Models

Teaches automated drawing creation from CAD models with proper annotation. Model-based drawings maintain associativity so updates propagate automatically.

Lesson 1 • Design for Assembly Principles

Covers part count reduction, self-locating features, and assembly sequence optimisation. Fewer parts and clearer assembly paths reduce labour cost and error rates.

Lesson 2 • Prototyping and Design Validation

Covers rapid prototyping methods and structured validation testing for mechanical designs. Physical prototypes reveal design flaws that analysis alone cannot predict.

Lesson 3 • Tolerance Analysis and Process Capability

Teaches worst-case and statistical tolerance stack-up analysis linked to process capability. Learners set tolerances that are achievable with selected manufacturing processes.

Lesson 4 • Fundamentals of DFM

Establishes core DFM rules for common processes including machining, casting, and forming. Applying DFM early prevents costly redesigns during production ramp-up.

Lesson 1 • Topology and Shape Optimisation

Covers density-based topology optimisation and shape sensitivity for lightweight structures. Learners generate optimised material layouts that meet stiffness and mass targets.

Lesson 2 • Multi-Objective Design Optimisation

Introduces Pareto front analysis and trade-off methods for competing design objectives. Learners navigate cost-performance-weight trade-offs using structured optimisation tools.

Lesson 3 • Finite Element Analysis for Design

Introduces FEA workflow including meshing, boundary conditions, and result interpretation. FEA validates structural designs and identifies stress concentrations before prototyping.

Lesson 4 • Robust Design and Taguchi Methods

Teaches parameter design and noise factor management using Taguchi orthogonal arrays. Robust designs maintain performance despite manufacturing variation and use conditions.
