,QUESTION 1 The design process step 3 is referred to as the
make stage. It is important to plan for this stage. Planning
includes those activities which are involved when working out,
in advance, how a product, process or system is to be produced
or realised before actually doing it. Make notes regarding the
materials needed by finding answers to the following questions:
a. What different types of material are needed? (2) b. What
should the quality of the different materials be? (2) c. What are
the sizes of the available raw materials? (3) d. Will the different
materials have to be cut to size? (5) e. Will the different
materials have to be shaped? (5) f. What does the final finish of
the product or prototype have to be? (3) [20]
Here are detailed notes for each part of the question regarding
the "Make" stage in the design process:
a. What different types of material are needed? (2)
• Types of Materials:
1. Structural Materials: These are used for the core
construction of the product, such as wood, metal,
plastic, or composites.
2. Functional Materials: These materials contribute to
the product’s functionality, such as electronic
components, fabrics, or insulating materials.
b. What should the quality of the different materials be? (2)
, • Quality Requirements:
1. Structural Integrity: Materials must be durable and
able to support the intended load or stress without
failure.
2. Consistency and Purity: Materials should be free of
defects and impurities to ensure reliability and
performance. For example, metal should be free from
rust, and plastics should be free from bubbles or
inconsistencies.
c. What are the sizes of the available raw materials? (3)
• Available Sizes:
1. Dimensions of Sheets/Panels: For materials like
plywood, metal sheets, or plastic panels, the standard
sizes could be 4x8 feet or 1x2 meters.
2. Lengths of Bars/Rods: Metal or wooden rods might
come in standard lengths such as 1 meter or 6 feet.
3. Sizes of Components: For electronic parts, sizes vary
based on the type and specification of the component,
such as resistors or microchips.
d. Will the different materials have to be cut to size? (5)
• Cutting Requirements:
1. Wood: Wood panels or beams will often need to be
cut to the precise dimensions required for the design.
2. Metal: Metal sheets or rods typically need to be cut to
fit the design specifications, requiring tools like saws
or laser cutters.
3. Plastic: Plastic sheets may need to be cut to size using
saws or precision cutting tools.
