1 Exploring Context and Factors Affecting the Design Process What are the 5 Ws? Exploring Context and Factors Affecting the Design Process The 5 Ws are who, what, where, when and why. When using Usability anthropometric data, designers often work from the 5 th to the 95 th percentile. True or false? Usability True. This ensures that the product is suitable for 90% of the population. Exploring Existing Designs Why must influence of fashion and style be considered when designing? 3 Exploring Existing Designs Designers need to know current trends in order to produce popular products. 3 New and Emerging Technologies Why are biodegradeable carrier bags a good use for bioplastics? 4 New and Emerging Technologies Biodegradeable carrier bags mean there will be less waste to fill landfill sites. 4 New and Emerging Technologies What does the circular economy encourage? 5 New and Emerging Technologies Circular economy encourages the re-use of energy, products and materials. 5

2 Sources of Energy Name three renewable energy sources. 6 Sources of Energy Renewable energy sources include solar, wind and water/tidal. 6 Sources of Energy How is energy transferred from power stations to homes and buildings? 7 Sources of Energy Energy is transferred from power stations to homes and buildings via the National Grid. 7 Wider Influences on Designing and Making What does the Mobius Loop symbol show? 8 Wider Influences on Designing and Making The Mobius Loop symbol shows that a product can be recycled. 8 Viability of Design Solutions What is a bill of materials? 9 Viability of Design Solutions A bill of materials is a list of all the materials and components needed for a product, plus their costs to purchase. 9 What is a rendered sketch? 0 A rendered sketch is a drawing that has colour, tone or texture added to it to make it more realistic. 0

3 What is sketch modelling? Sketch modelling is the process of creating a 3D sketch from a D shape using CAD. What do exploded drawings show? Exploded drawings show how all the parts of a product fit together. What does a diamond shape represent in a flow chart? 3 A diamond shape in a flow chart represents a decision. 3 Approaches to Designing Name three approaches to design. Approaches to Designing Three approaches to design are iterative design, usercentred design and the systems-based approach. 4 4 Properties of Materials Which has the greatest tensile strength metal or wood? Properties of Materials Metal has the greatest tensile strength. Wood has low tensile strength; metals have high tensile strength. 5 5

4 Factors Influencing Material Selection What is meant by functionality? 6 Factors Influencing Material Selection Functionality means whether a material has the right properties to meet the purpose of the product. 6 Paper and Board How many gsm does cartridge paper have? 7 Paper and Board Cartridge paper has 00 50gsm. 7 Paper and Board Name two chemicals that may be added during the manufacture of paper. 8 Paper and Board Chalk and dye may be added during the manufacture of paper. 8 Timber What does MDF stand for? Timber MDF stands for medium density fibreboard. 9 9 What is a non-ferrous metal? A non-ferrous metal is a metal that doesn t contain iron. 0 0

5 Give three examples of alloys. Examples of alloys include brass, pewter and solder. Polymers What is a typical use of both PP and HIPS? Polymers PP (polypropylene) and HIPS (High-impact polystyrene) are both used for packaging. Textiles What are polyester and acrylic produced from? Textiles Polyester and acrylic are both produced from oil. 3 3 New Developments in Materials Give examples of two technical textiles. 4 New Developments in Materials Kevlar and Marlan are examples of technical textiles. 4 Standard Components Name three types of standard component that can be used with paper and board. 5 Standard Components Clips, fasteners and bindings are standard components that can be used with paper and board. 5

6 Finishing Materials What is anodising and what metal is it used on? 6 Finishing Materials Anodising involves electrolysis to provide a corrosionresistant or colour finish to aluminium. 6 Structural Integrity When concrete is used to build buildings, what is it normally reinforced with? 7 Structural Integrity Concrete is normally reinforced with steel bars to make a composite material for building buildings. 7 Motion and Levers What is the name of this type of motion? 8 Motion and Levers This type of motion is called reciprocating motion. 8 Mechanical Devices Name three types of linkage. 9 Mechanical Devices Push pull, tongs and moving wings are all types of linkage. 9 Electronic Systems What is the name of this component circuit symbol? 30 Electronic Systems This component circuit symbol is a tilt switch. 30

7 Programmable Components Why would a driver be added to a circuit with a microcontroller? Programmable Components A driver would be added to enable an output device to draw a high current. 3 3 Modelling Processes What polymer material is useful for making a solid concept model? 3 Modelling Processes Polystyrene block is useful for making a solid concept model. 3 Wastage Name the different types of saw used for cutting timber. Wastage Tenon saws, coping saws, band saws, circular saws, fretsaws and jigsaws can all be used for cutting timber Additive Manufacturing Processes What is the most common method of joining fabrics together? 34 Additive Manufacturing Processes Sewing is the most common method of joining fabrics together. 34 Deforming and Reforming What does a perforation cutter do? Deforming and Reforming A perforation cutter makes a row of small holes in paper or card so that part of it can be torn off

8 Ensuring Accuracy What is the purpose of a jig when machining? 36 Ensuring Accuracy The purpose of a jig when machining is to ensure that the machining is carried out in the correct place on the workpiece and/or hold it securely. 36 Digital Design Tools What does CAE stand for? 37 Digital Design Tools CAE stands for Computeraided engineering. 37 Scales of Manufacture What type of manufacture is used to produce chocolate bars in large quantities? 38 Scales of Manufacture Mass production is used to manufacture chocolate bars in large quantities. 38 Large-Scale Processes: Paper, Timber and What is die-cutting used for? 39 Large-Scale Processes: Paper, Timber and Die-cutting is used to cut shapes and holes. 39 Large-Scale Processes: Polymers and Fabrics What is an overlocker and what is it used for? 40 Large-Scale Processes: Polymers and Fabrics An overlocker is a specialised industrial sewing machine, used to give seams and hems a professional finish or add decorative edges. 40
