Crown Icing Dispenser

Team: Cooper Gray, Abigail Hymas, Ben Mohlman, and Summer Wooten

Project Description

A birthday cake
  • Baking has become a popular hobby or lifestyle worldwide. Piping bags are the go-to tool for decorating baked goods.
  • By using these piping bags throughout the workday, it creates a lot of stress and wear on bakers’ hands.
    • Arthritis, joint or hand pain, and muscle fatigue are common ailments among full-time bakers.
  • Given the lack of available products addressing this issue, we worked together with our sponsor to develop a design that could assist bakers to help prevent hand discomfort and injury.
  • Our task is to create a product that enables bakers to use piping bags without applying pressure, thus relieving strain on their hands.

Conclusions

How Were Requirements Met

  • Prototype is easy to use
  • Compact design
  • Need to reduce weight
  • Enhance grip
  • Implement a more efficient pressure system
  • Improve consistency of frosting flow rate

Lessons Learned

  • Involve sponsor sooner and communicate better
  • Begin designing and testing earlier
  • Send prototypes sooner for feedback
  • Focus less on exploring many designs at first
  • Spend more time refining sponsor's original idea
  • Prioritize early testing over design exploration

Recommended Future Work

  • Optimize components for mass production with custom parts
  • Improve Arduino code for motor speed
  • Find better materials/designs for rollers and consider gear-like rollers for better bag grip
  • Get help from a process engineer for mass production and cheaper production
