Designing Engineering Products — WJEC Vocational Design and Technology

The WJEC Level 1/2 Vocational Award in Engineering (Technical Award) is a practical, hands-on qualification designed to introduce students to the world of engineering. It covers core engineering principles, including materials, processes, and the design cycle, with a strong emphasis on developing practical skills through project-based learning. This award is ideal for students who enjoy problem-solving, making things, and understanding how products are manufactured.

The qualification is structured around three main areas: engineering design, producing engineering products, and solving engineering problems. Students learn to interpret engineering drawings, select appropriate materials and tools, and use processes like marking out, cutting, shaping, and joining. The course also covers health and safety, quality control, and the importance of sustainability in engineering. By the end of the award, students will have a solid foundation for further study or entry-level roles in engineering.

This vocational award is part of the wider Design and Technology curriculum, bridging the gap between creative design and technical manufacturing. It prepares students for careers in fields such as mechanical, electrical, and civil engineering, as well as apprenticeships and A-levels in related subjects. The hands-on nature of the course makes it particularly valuable for developing transferable skills like teamwork, communication, and problem-solving.

• →Engineering design process: understanding the stages from identifying a need to evaluating a finished product, including research, specification, idea generation, and prototyping.
• →Materials and their properties: knowing the characteristics of common engineering materials (e.g., metals, polymers, composites) and how to select them based on strength, durability, cost, and sustainability.
• →Manufacturing processes: familiarity with techniques such as drilling, turning, milling, welding, and injection moulding, including their advantages and limitations.
• →Engineering drawings and tolerances: ability to read and interpret orthographic projections, isometric views, and dimensioned drawings, including understanding tolerances and surface finish symbols.
• →Health and safety: awareness of risk assessments, personal protective equipment (PPE), and safe working practices in a workshop environment.

• Award credit for clearly identifying and prioritizing functional requirements from the brief
• Award credit for demonstrating a range of design ideas with justification for selection
• Award credit for using correct technical drawing conventions (e.g., orthographic projection, dimensioning)
• Award credit for showing how feedback or testing led to design modifications

• 💡Always refer back to the design brief to ensure your solution meets all requirements
• 💡Use a variety of communication methods (sketches, CAD, notes) to show your design thinking
• 💡Clearly explain how your design solves the problem, using technical terms
• 💡Practice sketching and annotating quickly to manage time in exams
• 💡When answering design questions, always justify your choices with reference to material properties, cost, and manufacturing processes. For example, explain why you chose mild steel over aluminium for a car chassis.
• 💡In practical assessments, pay close attention to accuracy and finish. Use measuring tools correctly (e.g., callipers, micrometers) and check your work against the drawing tolerances.
• 💡For the written exam, use technical vocabulary precisely (e.g., 'ferrous', 'ductility', 'tensile strength') and show your working in calculations. This demonstrates depth of understanding.

• Focusing on aesthetics over functionality without linking to the brief
• Producing drawings that lack proper annotations or scale
• Failing to consider manufacturing constraints such as material properties or cost
• Not documenting the iterative process, leading to a final design with no evidence of development
• Misconception: Engineering is only about fixing things or working with heavy machinery. Correction: Engineering involves creative design, problem-solving, and innovation, from microchips to bridges.
• Misconception: Tolerances are not important as long as the part fits. Correction: Tolerances ensure parts function correctly and interchangeability; even small deviations can cause failure.
• Misconception: All metals are the same. Correction: Metals have vastly different properties (e.g., aluminium is lightweight but weak, steel is strong but heavy), and selection depends on the application.
