Problem Solving in Design Engineering. All Assessment Questions & Mark
Scheme [OCR H404/02]
Exam Resource Summary
The A Level Design and Technology June 2025 Paper 2: Problem Solving in Design
Engineering (OCR H404/02) – All Assessment Questions & Mark Scheme merges the
full official examination paper with its comprehensive mark scheme. This paper evaluates
students’ ability to apply engineering principles, design thinking, and analytical
problem-solving to real-world design challenges. Key areas assessed include mechanical
and electronic systems, materials and manufacturing processes, design optimisation,
sustainability, and innovation in engineering solutions. Students are expected to
demonstrate creativity, technical accuracy, and justification of design decisions through
structured, evidence-based responses. The merged format provides clear visibility of
examiner expectations, mark distribution, and model response approaches, making it
an invaluable tool for targeted revision, self-assessment, and enhancement of technical
reasoning and design problem-solving skills. This resource is essential for thorough
preparation for the June 2025 OCR A Level Design and Technology Paper 2 and for
building the advanced competencies required in future design engineering studies.

2* Page 3 of the Resource Booklet describes a Magirus Aircore TAF35 fire-fighting robot.
Such complex systems are developed through the collaboration of many different design and
engineering specialists.
Critically examine the significance of collaboration amongst engineers in the design and
development of complex systems such as the fire-fighting robot.
In your answer you must consider:
• the design phase of the product
• prototype and testing
• manufacture and production.
Refer to page 3 of the Resource Booklet and also draw on examples from your own studies. [12]
