Analysis 2

Design 1&2: Retractable/twist-out handlebar

  • How well does the prototype communicate the intended solution?
    • Ok. It is not yet clear which mechanism will be used to extend and retract the turn signal, and how it will be situated on/around the scooter handlebar. The intent is for the user to be able to use one simple movement/action to activate either turn signal.
  • How well does the solution seem to meet the needs of the user, in the user’s context?
    • This solution does meet the needs of the user, however we are not yet sure whether the user could easily use these functions as intended. Would they be able to twist the handle bar while accelerating/turning? How can we get the retractable pen mechanism to extend further than the length of the button?
  • How feasible will it be to successfully create a functional prototype over the next few weeks?
    • Once the mechanism is decided (especially the extend/retract feature), it will be feasible to successfully create a functional prototype.
  • Pros:
    • Easy access for user
    • Good visibility for all (drivers, riders, pedestrians)
    • Not large and bulky, does not take away from aesthetics of scooter
  • Cons:
    • Twist out involves twisting the handlebar while in motion. May be uncomfortable for some users.
    • Device could get stolen/removed from the scooter
    • Any exposed electronics have chance of being damaged (rough weather conditions, falling/beaten up scooter use)

Design 3: Swinging Lever

  • How well does the prototype communicate the intended solution?
    • Pretty well, just pressing a button to swing out the “flag” and pressing it again to bring it back in.
  • How well does the solution seem to meet the needs of the user, in the user’s context?
    • Should satisfy all the needs of the user: bright lights that are easy to see on both sides, easy access to button, ergonomic, not invasive to the rider.
  • How feasible will it be to successfully create a functional prototype over the next few weeks?
    • Should be relatively easy to complete. Need a motor, Arduino, LED lights, wiring, power supply, perhaps some 3D printed parts for the overall structure.
  • Pros:
    • Easy to use/access button
    • High visibility
    • Simple attachment
    • Ergonomic
    • Don’t have to remove hands from handlebar, just use index finger to press button
  • Cons:
    • Can be stolen
    • Depending on material/build quality, might not hold up in wind/weather
    • Mounting power supply/Arduino might be difficult
    • Swinging motion could be in the way of hands

 

Design 4: Foot Pedal

  • How well does the prototype communicate the intended solution?
    • Intended use is clear
    • Signal panel (with lights) could be confused/stepped on
  • How well does the solution seem to meet the needs of the user, in the user’s context?
    • Well, pedal is easy to use to provide solution
  • How feasible will it be to successfully create a functional prototype over the next few weeks?
    • Very feasible
  • Pros:
    • Allows user to keep hands on the handlebars to keep control
    • Eyes stay looking forward
    • All mechanical so no electronics needed (lower cost)
  • Cons:
    • Pedal could be stepped on by accident
    • Signal panel could be stepped on by accident
    • Would need to make models for each generation of lime/bird if dimensions change

 

Design 5: Pop out Integrated handlebar Redesign

  • How well does the prototype communicate the intended solution?
    • This is still a developing idea, with no physical prototype made yet. However, the sketch and video communicate the function of the mechanism that could be used.
    • The idea for this design would be to integrate this mechanism concept into the inside of the scooter handlebars, doing a complete handle redesign.
  • How well does the solution seem to meet the needs of the user, in the user’s context?
    • The mechanism/device will be housed internally, allowing the user to be able to interact with a more simple design and not worry about the mechanics or breaking.
  • How feasible will it be to successfully create a functional prototype over the next few weeks?
    • This will be on the more difficult side timewise (and potentially material-wise). This design is less developed than the other prototypes so far. However it may produce more successful results than an adaptive device.
  • Pros:
    • Integrated design, less worry for users
    • Most robust of all previous prototypes
    • Most waterproof
    • Avoids stealing/easy breaking
  • Cons:
    • Business model: might not be feasible for manufacturing companies to alter/use our new design
    • Kyle (from Lime) preferred to steer away from turn signals like a car; therefore would have less buy in from the target market we are trying to sell to (Bird & Lime).
    • No automatic retract

 

Moving Forward:

 

  • We will be focusing on creating a handlebar with integrated turn signal
