Engineering an Eating Utensil for Passive Tremor Cancellation

Literature Review

The tremor utensil market is saturated with a large variety of products that use different strategies to deal with hand tremors and covers an extensive price range. The two options currently available when choosing a stabilization utensil are active and passive tremor cancellation methods. ATC spoons use sensors and motors to actively stabilize the head of the utensil, preventing the food from spilling. PTC spoons, which is where this design falls, do not use any moving parts but instead utilize weights, handle designs, grips to counterbalance the tremor. These spoons are cheaper but provide less stabilization, a problem that is aimed to be fixed with this new design. Participants diagnosed with neurological diseases causing them to suffer hand tremors were asked to move peas and soup from a bowl on the table to a tube right next to the mouth with each spoon being tested against this design. The number of peas moved in each trial as well as a questionnaire about the feel of each utensil was gathered. After data analysis, it was concluded that the new design was the most effective in decreasing loss of food from the utensil relative to its cost. These findings support the applicability of this design against the current market leaders when taking into consideration the price to loss efficiency ratio. The data makes it clear that if this was to be available to the public that it would provide a compelling option with active stabilization like performance at a passively stabilized cost.
