Des Tech - Topic 2, 3, 4

# Topic 2

Design for manufacture

split into 3 different subtopic

* Design for materials
* design for process
* design for assembly

Design For Materials

Designing in relation to materials during processing, rather than designing for the final desired properties of the end product in use. 

Design for process

designing to enable the product to be manufactured using a specific process e.g. injection molding

Design for assembly

taking account of the assembling process at various levels

Embodied Energy

the sum of all energy required to produce that product

local combined heat and power

CHP generates electricity whilst also capturing usable heat that is produced in this process

Personal Energy Systems

E.g Solar Panels

is the small-scale generation of heat and electric power by homes (also small businesses and small communities) to meet their own needs. \n •It is an alternative or can supplement traditional centralized grid-connected power. \n •Lower negative impact on the environment \n •Lower costs for the consumer \n •High initial capital cost \n •also known as micro-generation

Mitigation

directly stopping or reducing emissions

clean tech

a product that reduces waste and requires as few non renewable resources as possible

Drivers For Clean Tech (what makes a company go green)

1. social - how consumers affect a company’s way of production
2. political - radical and incremental solutions
3. economical - how regulations affect a company’s way of production

Incremental Solutions

predictable development, that takes time. but has exploitation and small potential for market growth

Radical Solutions

exploration of new technologies, high potential of market growth, creation of new industries, improved reputation, but is unpredictable, and high uncertainty of success

End of Pipe

a method used to remove already formed contaminants typically at the end of the process of production

CAD

Computer Aided Design

Adv

* easily shareable
* easily editable
* iterations can be made with ease

Dis Adv

* High set up cost (only for multiple systems)
* initial learning difficulty
* not very creative

LCA

Life Cycle Analysis

* Pre-production (extraction of material)
* Production
* Distribution (includes packaging)
* Utilisation
* Disposal

Cradle To Cradle

living with the earth rather than on the earth

# Topic 3

Conceptual Modeling

a description of a proposed system in terms of a set of integrated ideas and concepts about what it should do

Low Fidelity

* cheap
* fast

Medium fidelity

* more refined
* fast
* CAD
* still rough

High fidelity

* fine details
* longer process
* to scale
