Adaptable Spoon
02

Project Goal:
In three weeks, develop a spoon to allow teens (ages 12-18) with arthrogryposis to feed themselves independently using their available range of motions. Create a video to describe and demonstrate the final design solution. The spoon should have the following features:
-
Allows teens to eat comfortable and quickly
-
Hold a similar amount of food as typical spoon
-
Accommodates for various (limited) ranges of motion
-
Is light-weight and durable
-
Is low-cost
-
Is usable by teens with a weak grip

Design Process & Brainstorming
Design Criteria:
Size (length)
Size (width)
Capacity
Weight
Durability
Usability
Aesthetics
Cost
> 6.5 in, < 7.5 in
< 4 in (if crossbeam), < 2 in
Must hole 8-15 mL of liquid
< 80 grams
Withstand a 3 ft. drop
Must be easily gripped
Available in 3+ colors
< $20
Reasoning:
Range of average spoon, would fit in a dishwasher
Average spoon = 1.25-1.5 in., wider spoon would still fit in a dishwasher
Average range of spoon capacity
Average spoon = 25g, ergonomic grip would increase capacity
Must be durable if dropped while eating
Must be gripped with little to no finger flexion to be usable
Makes the product more enjoyable for teens
Low cost makes the spoon more accessible and production easier
Other Manufacturing Techniques
-
The majority of plastic spoons are injection molded which makes them durable and low cost
-
Metal spoons are cut from metal and pressed/formed into the correct shape. These spoons are mass-producible and low cost
-
Rubberized or foam handles are glued to a metal base. The glue used must be water-resistant and high temp-resistant for dish washers

Brainstorming
-
Brainstormed individually
-
Created new ideas based on original ideas
-
Used common sense elimination
-
Screened ideas to determine which ideas would be best to prototype (seen below)
