  • Investments are what we have to put into at each stage in order to move to the next.
  • Final Thesis Presentation For Dell

    1. 1. Sustainable Desktop Computer<br />BrendenMacaluso, Senior thesis project University of Houston 2007/2008<br />
    2. 2. Technology makes our lives better, but…<br />
    3. 3. we have a bit of a problem <br />
    4. 4. Computes are disposable…<br /> 3-5 year service life<br />Computers are disposed of because<br />a) have become outdated<br /> b) failure of internal electronic component<br />
    5. 5. Approx. 500 million waste computers in the U.S<br />Internal components contain toxic heavy metals, such as mercury, cadmium, and lead. <br />Computer cases are majority of physical waste <br />Current casing makes dismantling for recycling difficult<br />
    6. 6. How do we make a more sustainable solution ?<br />
    7. 7. Middle: Us (the user)<br />Sustainability & Product Lifecycle<br />Front end:<br />before it gets to us<br />Back end:<br />when we’re done using it<br />
    8. 8. Stages<br />2. Manufacturing<br />3. Packaging<br />4. Transportation<br />1. Material production<br />energy<br />energy<br />energy<br />energy<br />resources<br />resources<br />resources<br />resources<br />time<br />time<br />time<br />time<br />labor<br />labor<br />labor<br />labor<br />Front end:before it gets to us<br />Investments<br />
    9. 9. Back end: when we’re done with it<br />Unplanned<br />Planned<br />Fate<br />Trash<br />Recycle<br />Repurpose<br />Easy<br />Difficult<br />
    10. 10. Front end: before it gets to us<br />Back end:when we’re done using it<br />Unplanned<br />Planned<br />Stages<br />2. Manufacturing<br />3. Packaging<br />4. Transportation<br />1. Material production<br />Fate<br />Trash<br />Recycle<br />Repurpose<br />energy<br />Easy<br />Difficult<br />Investments<br />resources<br />time<br />labor<br />Middle: Us (the user)<br />Reduce investment at each stage<br />Planned & easy to implement fate<br />Flexibility in usage<br />Action<br />Sustainable Solution<br />
    11. 11. How do we break a computer down to its basic elements ? <br />
    12. 12.
    13. 13.
    14. 14.
    15. 15. Plastic components<br />Takes little to no wear<br />Recyclable Polystyrene<br />What designers are designing <br />
    16. 16. Metal components<br />Little to no wear<br />Majority of computer body<br />Recyclable steel <br />
    17. 17. Electronics<br />Limiting lifespan factor “out dated”<br />Toxic components<br />MUST be disposed of properly<br />
    18. 18. Breakdown<br />Everything else<br />Case:<br />150+ parts<br />300+ manufacturing operations<br />Internalized electronics:DVD R/RW drives wireless adaptors card readers additional storage<br />Misc:<br /> Cables, connectors, labels, hardware<br />3 main components<br />Desktop Computer<br />Motherboard w/processor & memory<br />Excess<br />Hard drive<br />Power supply<br />
    19. 19. Design Statement<br />Make a sustainable computer that:<br />Reduces total number of materials, parts & manufacturing operations<br />Uses easily renewable materials & low impact manufacturing processes<br />Easily dismantled, recycled & allows for reuse of parts<br />How are we going to do it?<br />
    20. 20. Case<br />Electronics<br />Minimize<br />Minimize<br />Externalize<br />Choose<br />Choose<br />Front end<br />Number of case parts<br />Number of Manufacturing operations<br />Number of electronic parts<br />Efficient engineered “off the shelf” components (integrated parts, laptop hard drive, USB/SATA connections)<br />Single renewable & recyclable material<br />Manufacturing operations w/low impact<br />“Optional” components (added as needed: DVD R/RW, wireless)<br />
    21. 21. Computer 1<br />Computer 2<br />Externalize optional components<br />Middle<br />Flexibility in usage<br />CD/DVD R/RW <br />Wireless <br />Additional storage<br />
    22. 22. Externalize optional components<br />Middle<br />Flexibility in usage<br />Plug and play/easy to swap components<br />User customization <br />Components are not “mentally tied” to a particular computer and are separate, thus can be used on other machines<br />Maximize component & computer life separately <br />
    23. 23. Case<br />Electronics<br />Dismantle<br />Minimize<br />Minimize<br />Recycle<br />Recycle<br />Externalize<br />Back end<br />Number of electronic parts discarded at a time<br />100%<br />Opportunity to easily recycle components<br />Simple<br />Physical quantity of parts discarded<br />reuse external components<br />
    24. 24. Concept: cardboard computer?<br />
    25. 25. Plying corrugated cardboard experiment<br />
    26. 26. Test Prototyping<br />
    27. 27. Final Design<br />1 Material<br />2 Case components<br />3 Electronic components<br />4 Manufacturing processes<br />12 Die patterns<br />
    28. 28. Assembly<br />
    29. 29. Details…only what you need<br />
    30. 30. Tear it open…<br />
    31. 31. And get started!<br />
    32. 32. Can be positioned vertically or horizontally<br />
    33. 33. Need a component? Just plug it in a USB<br />
    34. 34. Corrugation is the ventilation<br />
    35. 35. Unwrap for service or to recycle<br />
    36. 36. Reduce-Reuse-Recompute<br />
    37. 37. Sustainable Desktop Computer<br />
