Final Project Questions to Answer…

• What will it do?

  • This is an adjustable desk within a range of at least 450mm to at least 1,100mm in height. It can be adjusted according to the user's condition(sleepy, leg or back aches, or height is not right). In addition, a heater is located in the middle of the desk, so you can use it warmly in winter. Like "Kotatsu" in Japan. (Exceptionally, heating is not available when standing.)

• Who has done what beforehand?

  • Height Control Desk

  • Rafael's FLOW DESK Link
    - His desk seems to move from 700mm to 1100mm in height. But my desk will move from 400mm to 1100m.
    - His desk has only two legs.
    - He also used an actuator to adjust the height of his desk. I will make a height control device. These are the differences between him and me.
  
  
  • Kadin Feldis's Final Project Link
    - His desk seems to move from 700mm to 1100mm in height. But my desk will move from 400mm to 1100m.
    - His desk has only two legs.
    - He also used an actuator to adjust the height of his desk. I will make a height control device. These are the differences between him and me.
  
  
  • Luay's Final Plan Link
    - I have the same idea as myself. But it looks like he's focused on portable. He doesn't have any work from the middle. If he had finished it, it would have been of great help to me.
  
  

  • HEATER

  • Murad Saadeh's fab corn Link
    - He didn't make a heater. He used a nicrome heating wire as a heating device.
  
  
  • As far as I know, "Kotatsu" in Japan is not adjustable in height, and there are desks without heaters that can be adjusted in height, but only considering sitting or standing.

• What will you design?

  • Desk
    • Shape (not the right-angled shape of the default desk)
      Structure(functioning as a desk's height)
      A Heater Frame
      
  • Remote control (if I have enough time to make the above things)
  • The electronics and control systems for my desk
    • The motor needs to be controlled.
      It must include the up-down stop feature
      The heater must be controlled
      

• What materials and components will be used?

  • Desk
    • External Appearance : plywood
      Internal Mechanical Structure : 3D printer's plastic
      A Heater Frame : plywood and stainless
      
  • Remote control (if I have enough time to make the above things)
    • External Appearance : plywood
      

• Where will they come from? & How much will they cost?

  • Material Type	Size&Quantity	Price	Link
    Birch Plywood	12T (1220*2440) 70UDS *2	92,000*2=194,000	Link
    Stepper Motor(NEMA17)	*8	23,300*8=186,400	Link
    Long Bolt	1M *10	22,990	Link
    Coupling	*8	10,000*8=80,000	Link
    Incandescent Lamp	*2	5,990*2=11,980	Link
    Socket	*2	4,890/5*2=1,956	Link

  • The unit of money is WON(₩) in Korea.
  • I need about 250($) dollars(300000WON).
  • Almost available on the local open market

• What parts and systems will be made?

  • Almost everything will be made
  • board with a desk plate
  • leg of a desk
  • low-level device on the desk
  • remote control (not yet confirmed)
  • board with sensors
  
  
  • Something to buy
  • Incandescent bulb(Be respoSsible for heating)
  • Kotatsu's quilt(buy an appSopriate blanket and reprocess it)

• What processes will be used?

  • Desk External Appearance :
    CAD design → CNC → Sending → Assemble
  • Internal Mechanical Structure :
    CAD design → 3D Printing → Assemble
  • Remote control : CAD design → CNC or 3D Printing
  • Control Unit : PCB design → milling & stuffing → Microcontroller programming

• What questions need to be answered?

  • What else can be used as a heater besides incandescent bulbs?
  • What mechanical structure can I make the movement I want?
  • What should I do to make the legs of the desk move smoothly?

• How will it be evaluated?

  • Is the height of the four legs equal when they move?
  • Can the legs of the desk withstand a load of at least 60kg?
  • Does the heater's temperature control work well?
  • Will the power turn off when the temperature exceeds 60 degrees Celsius?
