• What to do about it?

  • 3D Scan and Design
    3D Scan and Design
  • A very preliminary idea was to create an experience that would 3D scan a person's body and custom fit a seat to their exact proportions. This failed in several ways, as it did not eliminate an organizations need of buying a new seat for every differently proportioned person, and would have actually limited the accessibility of monosking to people who were able to and willing to purchase a custom seat.

  • Many considerations were necessary when brainstorming different designs.  The most challenging of these was the importance of keeping any design modifications very low profile, so that they did not get in the way during skiing.  Our first idea was to create a track that a connection on the bottom of the seat would slide along and then fix to in an ideal position. This design suffered because of the difficulty of securely fixing the track to a specific point.  Though possible, this would involve adjusting the width from the underside of the seat, which violated a design constraint that the seat adjustments must be located either on the side or back of the seat. 

  • Incremental Weight System

    An additional design that came to mind was based on how a lat pull down machine works in the gym. When adjusting the system for different amounts of weights, the user must slide out a rod and place it in the desired slot as seen in the picture. The idea we came about for the seat design was very similar. It used the sliding rod application to allow for multiple different seat sizes. The seat would allow the outer wings/armrests to slide in and out and lock into place using a screw device to accomodate whatever size is needed for the user. It was identified that while this isn't 100% fully adjustable, it is a design moving the right direction to allow for one seat to accomodate more users. 



  • Ratchet Track

  • Because ratchet structures are already used in snowboard bindings, they were a good idea for a design because of ski instructors' familarity with the systems.  The ratchet track would be in several locations on the bottom of the seat, as well as on the back part of the seat to increase structual integrity. The largest flaw of this design was when the seat is adjusted to the smallest setting, excess material would be sticking out the sides of the seat, which violates the design constraint of keeping the sides free of material. 

  • Vise Fix

  • The final design considered for allowing a moving system capable of fixing to a certain point was copying the idea of a vise clamp.  Changing the design to be more low profile, this would allow for the 'opening' and 'closing' of a track that would be open when making width adjustments. When the seat is in the correct position, the clamp can be cranked shut with an adjustable handle that fits into a socket built into the seat, allowing for the mechanism to be flush with the rest of the seat.
