Week 17

Applications and Implications.

ASSIGNMENT:

1.) Propose a final project that integrates the range of units covered, answering:

- WHAT WILL IT DO?

My final project will be a concept helmet for urban use with the ability to self reinforced in necessary situations such as falls or minor accidents.

The idea was born from the keys generated in human skin by subjecting certain body parts to continuous frictions, the human body knows where and when the skin needs to be reinforced. The thickening of the skin is a protective response of the body; to prevent painful blisters appear.

For more details you can read the concept of my idea here:

- WHO'S DONE WHAT BEFOREHAND?

I searched a lot about products or projects similar to mine. There are a variety of urban helmet on the market, but I only found one with similar characteristics to my proposal:

HOVDIG AIRBAG HELMET
- WHAT MATERIALS AND COMPONENTS WILL BE REQUIRED?
  • Manufacturing:
  • - Polyurethane foam.
  • - Resin POX BAK 1206.
  • - Synthetic Jute.
  • - Polycarbonate Sheet.
  • - Smooth-On OOMOO 25.
  • - ABS filament Makerboot.
  • Electronics:
  • - Ultrasonic sensor HC-SR04.
  • - Power supply.
  • - Microcontrolers.
  • - LEDs.
  • - Solenoids.
- WHERE WILL THEY COME FROM?
  • FABRICATION MATERIALS:
  • - Polyurethane foam: local supplier.
  • - Resin POX BAK 1206: got in the Fab Lab Tecsup.
  • - Synthetic Jute: got in the Fab Lab Tecsup.
  • - Polycarbonate Sheet: got in the Fab Lab Tecsup.
  • - Smooth-On OOMOO 25 got in the Fab Lab Tecsup.
  • - ABS filament Makerboot. got in the Fab Lab Tecsup.
  • ELECTRONICS:
  • - Ultrasonic sensor HC-SR04: local supplier.
  • - Power supply: got in the Fab Lab Tecsup.
  • - Microcontrolers: got in the Fab Lab Tecsup.
  • - LEDs: got in the Fab Lab Tecsup.
  • - Solenoids: local supplier.
- HOW MUCH WILL IT COST?

It is not the final cost, I still need to buy and find out the price of some parts.

-WHAT PARTS AND SYSTEMS WILL BE MADE?
  • HELMET:
  • Molds.
  • Vacuum chamber.
  • 3d printed parts.
  • ELECTRONICS:
  • Microcontroller boards.
  • Control codes.
    • - WHAT PROCESSES WILL BE USED?
  • 3D printing.
  • Molding and casting.
  • Composites material.
  • Electronic milling.
  • Programming.
  • Laser cut.
    • - WHAT TASKS NEED TO BE COMPLETED?
  • Design and mill 3D mold for my helmet.
  • Design and 3D print some pieces for the helmet.
  • Design and make a vacuum chamber.
  • Design and cut the fabric for the composites material.
  • Design and mill the circuit for the electronic part for my helmet.
  • Whrite the code to control the electronic sensors of the helmet.
    • - WHAT QUESTIONS NEED TO BE ANSWERED?
  • What complications might have to machine the mold for forming a helmet in the Fab Lab with ShopBot?
  • What would be the minimum distance that the sensors can read to activate the mechanism of self reinforcing the helmet? Testing distances.
  • What alternative materials could make a helmet combining digital and manual production? Experience and testing in the Fab Lab Tecsup.
    • - WHAT IS THE SCHEDULE?

    There are 3 weeks left for my final presentations, 15nd june.

    - Week 1: Testing mechanism for the helmet reinforcement.

    - Week 2: Fix the 3D design and make the molding and casting of the helmet.

    - Week 3: build the helmet, make some test and solve final issues and make the documentation.

    - HOW WILL IT BE EVALUATED?

    For the project to succeed it needs to show at less the functionality of concept helmet having the capacity to reinforced themself.

    This week I made ​​an extra project , a vacuum chamber . You can see it by clicking here.
