Engineering Design

Engineering –

The systematic application

of mathematical, scientific, and technical principles

that yields a tangible end product

that meets our needs or desires.

The design and

manufacture of

products.

Energy Considerations

• How is energy developed on the moon?

• From where does the fuel come?

• What are safety concerns?

• For what will the energy be used?

Ingenuity Design Firm

Shelter Design

• What type of environment is on the moon?• From what do inhabitants need protection?• How does temperature impact the shelter design? • Radiation? • Length of the day? • How will structures be constructed? • What will they look like?

Transportation

• How will we get to the moon and back to the Earth?

• How will supplies be carried? • As weight goes up, so does the cost and

propulsion requirements. How does this impact shelter design?

• How do we travel on the surface of the moon?

Ingenuity Design Firm

Sustainability

• What will people eat on the moon? • From where will food come? • How will they get, transport, and filter

water? • Where will waste from humans be

contained? • What can and can not be recycled? I - 2

8 CONSTRAINTS on the ENGINEERING DESIGN PROCESS

1. Safety – is the product safe to use/construct?2. Reliability – will it work consistently over time?3. Cost – is it affordable?4. Quality Control – does it meet customer requirements?5. Environmental Concerns – does it harm the natural or

human environment negatively? 6. Manufacturability – can it be made?7. Maintenance – how easily can it be maintained or

upheld?8. Ergonomics – how efficiently can the human body

utilize it?
