Laptray | Perspectives in Assistive Technologies (Stanford ENGR110/210)

Increasing Daniel's ability to carry objects independently. Prior to this laptray, Daniel was restricted to carrying objects that only fit in his fanny-pack or rested on top of his legs.

  • Challenges
  • Inability to carry objects
  • Solutions
  • Discrete laptray
  • Intuitive design

For years, I watched people struggle to carry items while operating a manual wheelchair. At first, I worked with a group of undergraduate students from UC Berkeley to explore a solution to this design problem. The students came up with ideas and protypes that fell short in final analysis. I later came up with a design for a wheelchair laptray attachment, where the user can flip up and reveal a tray over their lap to carry objects while wheeling. I partnered with three undergraduate students from Stanford University through the Engineering 110/210 class. It was an iterative process of many designs, identifying effective materials, and ways to make the device structurally sound and functional. Through this two-quarter project, we created a working laptray that facilitates independence for manual wheelchair users.
