Physical properties & Aesthetic properties
A warp along the length of the face of the wood.
What is Bowing?
The ability of a material to withstand being pushed or squashed.
What is Compressive strength?
Often referred to as the "eureka moment", a sudden image of a potential solution is formed in the mind, usually after a period of thinking about a problem.
What Act of insight (innovation strategies)?
Designing taking account of assembly at various levels, for example,component to component, components into sub-assemblies and subassemblies into complete products.
Design for assembly
What is an alloy?
A mixture of a metal with at least one other element (metal or non-metal)
When timber is subject to decay and attack by fungus.
Dry rot
The ability of a material to be drawn or extruded into a wire or other extended shape.
Ductility
A legal right created by the law of a country, that grants the creator of an original work exclusive rights to its use and distribution, usually for a limited time, with the intention of enabling the creator (e.g. the photographer of a photograph or the author of a book) to receive compensation for their intellectual effort.
What is © Copyright?
Designing a product so that when it becomes obsolete it can easily and economically be taken apart, the components reused or repaired, and the materials recycled.
Design for disassembly
What is the primary difference between Ferrous and Non-Ferrous metals?
Ferrous metals contain iron (and are usually magnetic); Non-Ferrous metals do not contain iron.
The mass per unit volume of a material. Its importance is in portability in terms of a product’s weight and size. Design contexts include, pre-packaged food (instant noodles) is sold by weight and volume, packaging foams.
What is Density?
The extent to which a material will return to its original shape after being deformed.
Elasticity
The wide acceptance (and sale) of a product.
What is Market Diffusion?
Designing in relation to materials during processing.
Design for materials
Which type of plastic can be reheated and reshaped multiple times?
Thermoplastics.
Relates to the amount of matter that is contained with a specific material. It is often confused with weight understandably as we use Kg to measure it. It is a constant whereas weight may vary depending upon where it is being measured.
What is Mass?
A volume production process where products and components are production moved continuously along a conveyor. As the product goes from one workstation to another, components are added until the final product is assembled.
What is Assembly line?
Over time, products wear out and break down. If parts are no longer available, the product can no longer work in the way it originally did. Also, if a service vital to its functioning is no longer available, it can become obsolete.
What is Functional obsolescence?
Designing to enable the product to be manufactured using a specific manufacturing process, for example, injection moulding.
Design for process
This property measures how easily a material can be shaped or molded without breaking.
Plasticity.
A measure of the degree of increase in dimensions when an object is heated. This can be measured by an increase in length, area or volume. The difference can be measured as the fractional increase in dimension per kelvin increase in temperature.
What is Thermal Expansion (expansivity)?
A production method used to manufacture, produce or process materials without interruption.
What Continuous flow?
The basic configuration stays the same, but one or more key components are changed.
What is Modular innovation?
Designers design specifically for optimum use of existing manufacturing capability.
Design for manufacture
This heat treatment involves heating a metal and then cooling it rapidly to increase hardness.
Quenching.
