Resistant Materials

Resistant Materials

1. Art Deco

   • Shapes such as spheres, polygons, rectangles, trapezoids, zigzags, chevrons, and sunburst motifs
   • Often arranged in symmetrical patterns
   • Modern materials such as aluminum, stainless steel, Bakelite, chrome, and plastics are frequently used. Stained glass, inlays, and lacquer are also common
   • Bright contrasting colors used

2. Specification

   • 1. Materiials used and why
   • 2. Shape/ Ergonomics
   • 3. Color scheme
   • 4. Function
   • 5. Tools required
   • 6. Target audience/ theme

3. Designing & Developing ideas

   • Developing
     • Model - a scaled down graphic representation of a design.
     • Prototype - a life size working model of a design used for testing development and evaluation.
     • Mock-up - a model of a product built for study, testing and display.
   • Designing
     • CAD
       • Designs can be modelled on-screen and viewed from any angle.
       • Reaction to outside forces such as wind flow and pressure can be modelled.
       • Control sequences can be simulated before working on the actual material.

4. Evaluating ideas

   • Design ideas should be evaluated to make sure they meet product specification and are of a good quality
   • Does it meet the design need or situation?
   • Does it meet the needs of the intended users?
   • Does it fit the purpose for which it is intended?

5. 6R's

   • Reduce -is it possible to reduce the amount of materials used? This will help to protect valuable resources.
   • Rethink - is there a better way to solve this problem that is less damaging to the environment?
   • Refuse - this means not accepting things that are not the best option for the environment. For example, is the packaging really needed?
   • Recycle - could recycled materials be used, or is the product made from materials that are easy to recycle
   • Reuse - could the product have another use? Could its parts be used in other products? Is this information clearly communicated on the product? This will extend its life.
   • Repair - is the product easy to repair? This will extend its life.

6. CAD CAM

   • CAD
     • Can be more accurate than hand-drawn designs - it reduces human error.
     • You can save and edit ideas, which makes it easier and cheaper to modify your design as you go along.
     • The software itself can be expensive so initial costs are high. There are free software packages though.
     • Staff need to be trained how to use the software, which also adds to costs.
   • CAM
     • In large-scale production, the results are always the same.
     • Enables very high accuracy levels in large-scale production.
     • The software itself is expensive so initial costs are high.
     • Can be slower than traditional methods for one-off or low-volume production.

7. Batch Production

   • is when a small quantity of identical products are made.
   • Batch production may also be labour intensive, but jigs and templates are used to aid production.
   • Batches of the product can be made as often as required.

8. Product Analysis

   • What is the function and purpose of the product?
   • What are the different parts of the product and how do they work together?
   • How does the product use shape, form, color, texture and decoration?
   • What materials and components are used to make the product?
   • Which processes were used to make the product?
   • Who would buy this product?
   • How well does the product do its job compared with other similar products?
   • What is unique about the product?

9. Research

   • Primary
     • First hand, unpublished data collected
     • E.g. Questionnaires, Interviews and surveys
   • Secondary
     • Published data which others have collected
     • E.g. Data collected from Internet, Articles and other companies
