- Biomass: Fuel is burnt to generate steam from heated water, which turns turbines
Planned obsolescence: Many companies rely on consumers continually buying products to survive. This is why they
deliberately design their products to become obsolete, die, or break, so that consumers come back to buy the
newest version of the product. Applies to products such as phones, kitchen machines and washing machines.
However, this can be a positive in the medical industry to prevent infection.
Sustainability: Meeting the needs of the present without compromising the ability of the future generations to meet
their own needs. Applies to economic development, food production, environment, energy.
Cradle to Cradle: Opposed to cradle to grave, all material inputs and outputs are seen either as technical or
biological nutrients. Can be made from reused or recycled materials. One example is Adidas trainers made with
recycled plastic or Aeron Chair being sparing of natural resources yet still making products durable, repairable and
recyclable
Fair Trade: Establishing better prices, working conditions and terms of trade for farmers and workers.
Topic: Chapter 4 – Design thinking and communication
Communicating Design Solutions
Design teams usually must pitch ideas to clients and stakeholders. Technological innovations let designers collaborate
on more complex projects. Collaboration could be extremely important for the result to be successful.
2D and 3D sketching
Sketches with annotations are easy and fast. Details and notes help to make a more realistic view and to make it clearer.
Sketching are used:
At the start of the design task (understand problems and contexts; to understand wants and needs),
Initial ideas (usually rough but they are quick and are used to understand the idea rather than details),
Explain the design concept (explains the idea and must be readable to those outside the process), and
Sell the product (can be sketching the product or making a story board).
2D sketches look flat and show two dimensions with possibly different line thicknesses, colour and textures.
They can be done with pencil, pen, or fine liners.
Perspective drawing
This 3D technique makes more realistic sketches as the object looks smaller when it is further away.
One-point perspective is where horizontal and vertical lines meet at one vanishing point
Two-point perspective uses two vanishing points. It creates more believable drawings
The vanishing points are on the eye-line
