  • Investments are what we have to put into at each stage in order to move to the next.

Transcript

  • 1. Sustainable Desktop Computer
    BrendenMacaluso, Senior thesis project University of Houston 2007/2008
  • 2. Technology makes our lives better, but…
  • 3. we have a bit of a problem
  • 4. Computes are disposable…
    3-5 year service life
    Computers are disposed of because
    a) have become outdated
    b) failure of internal electronic component
  • 5. Approx. 500 million waste computers in the U.S
    Internal components contain toxic heavy metals, such as mercury, cadmium, and lead.
    Computer cases are majority of physical waste
    Current casing makes dismantling for recycling difficult
  • 6. How do we make a more sustainable solution ?
  • 7. Middle: Us (the user)
    Sustainability & Product Lifecycle
    Front end:
    before it gets to us
    Back end:
    when we’re done using it
  • 8. Stages
    2. Manufacturing
    3. Packaging
    4. Transportation

  • 11. How do we break a computer down to its basic elements ?
  • 12.
  • 13.
  • 14.
  • 15. Plastic components
    Takes little to no wear
    Recyclable Polystyrene
    What designers are designing
  • 16. Metal components
    Little to no wear
    Majority of computer body
    Recyclable steel
  • 17. Electronics
    Limiting lifespan factor “out dated”
    Toxic components
    MUST be disposed of properly
  • 18. Breakdown
    Everything else
    Case:
    150+ parts
    300+ manufacturing operations
    Internalized electronics:DVD R/RW drives wireless adaptors card readers additional storage
    Misc:
    Cables, connectors, labels, hardware
    3 main components
    Desktop Computer
    Motherboard w/processor & memory
    Excess
    Hard drive
    Power supply
  • 19. Design Statement
    Make a sustainable computer that:
    Reduces total number of materials, parts & manufacturing operations
    Uses easily renewable materials & low impact manufacturing processes
    Easily dismantled, recycled & allows for reuse of parts
    How are we going to do it?
  • 20. Case

    Front end
    Number of case parts
    Number of Manufacturing operations
    Number of electronic parts
    Efficient engineered “off the shelf” components (integrated parts, laptop hard drive, USB/SATA connections)
    Single renewable & recyclable material
    Manufacturing operations w/low impact
    “Optional” components (added as needed: DVD R/RW, wireless)
  • 21. Computer 1
    Computer 2
    Externalize optional components
    Middle
    Flexibility in usage
    CD/DVD R/RW
    Wireless
    Additional storage
  • 22. Externalize optional components
    Middle
    Flexibility in usage
    Plug and play/easy to swap components
    User customization
    Components are not “mentally tied” to a particular computer and are separate, thus can be used on other machines
    Maximize component & computer life separately
  • 23. Case
    Electronics
    Dismantle
    Minimize
    Minimize
    Recycle
    Recycle
    Externalize
    Back end
    Number of electronic parts discarded at a time
    100%
    Opportunity to easily recycle components
    Simple
    Physical quantity of parts discarded
    reuse external components
  • 24. Concept: cardboard computer?
  • 25. Plying corrugated cardboard experiment
  • 26. Test Prototyping
  • 27. Final Design
    1 Material
    2 Case components
    3 Electronic components
    4 Manufacturing processes
    12 Die patterns
  • 28. Assembly
  • 29. Details…only what you need
  • 30. Tear it open…
  • 31. And get started!
  • 32. Can be positioned vertically or horizontally
  • 33. Need a component? Just plug it in a USB
  • 34. Corrugation is the ventilation
  • 35. Unwrap for service or to recycle
  • 36. Reduce-Reuse-Recompute
  • 37. Sustainable Desktop Computer
