Study Notes
Materials and Manufacturing
- Galvanizing is a surface finish used to protect steel frames from corrosion.
- It involves applying a zinc coating to the steel to prevent rust.
Design Strategies
- Reverse engineering and product analysis are two important design strategies used in the iterative design process.
- Reverse engineering involves disassembling and analyzing existing products to understand their design and functionality.
- Product analysis involves evaluating the design, materials, and functionality of existing products to identify areas for improvement.
Materials and Properties
- Stock size/form refers to materials that are produced in standard sizes or forms, making them readily available for use in design and manufacturing.
- The advantages of stock size/form materials include:
- Convenience and efficiency for designers and manufacturers
- Reduced production time and costs
- Wide availability and accessibility
Environmental Concerns
- Environmental issues are a global concern, and product designers and manufacturers must consider the environmental impact of their designs.
- Polymers are a common material used in product design, but they have both advantages and disadvantages:
- Advantages: lightweight, durable, and versatile
- Disadvantages: non-biodegradable, contribute to pollution and waste
Manufacturing and Materials
- Plywood is a regenerated material made from wood fibers, making it a sustainable and eco-friendly option.
- It is suitable for manufacturing storage units due to its:
- Strength and durability
- Aesthetically pleasing appearance
- Eco-friendly properties
Design for Sustainability
- Disposable BBQs have several environmental issues associated with their use, including:
- Litter and pollution
- Harm to wildlife and ecosystems
- Contribution to climate change
- Designing a reusable portable unit for disposable BBQs can help address these issues.
- The design should consider safety features, environmental impact, and innovative design solutions.
