1. Material selection for design elements like plywood, MDF, recycled card, and foamboard; justifications based on properties such as strength, cost, and environmental impact.

2. Prototyping methods in school workshops, including cutting, shaping, and assembling components; use of tools and safety considerations.

3. Design solutions for pivot mechanisms, locking systems, and adjustable components; detailed sketches and technical annotations.

4. Development of packaging nets, protective covers, and display features for products like glasses and chocolates; integration of functional and aesthetic aspects.

5. Adjustments to designs for usability and problem resolution in items like plant stands, shape sorters, and electric toothbrushes; identification and solutions for design flaws.

6. Batch and mass production considerations, including resource planning, prototype testing, and energy efficiency in product designs.

7. Development of innovative mechanical systems for adjustability and locking mechanisms in designs like height-adjustable tables, clothing hangers, and barriers.

8. Detailed renderings of complete design solutions incorporating all developed features, emphasizing usability, aesthetics, and practical implementation.
