CO2 Mechanism
This project included part design for multiple manufacturing processes, as well as specifying off the shelf parts and working with vendors. Ultimately the assembly was made at a contract manufacturer in China.
Overview
Problem Statement
This subsystem was created to allow a user to puncture a CO2 bottle for use in carbonated beverage dispensing. The system must seal extremely well and repeatably, include a solenoid valve for controlled dispensing, and include a safety relief valve.
Challenges
Tight timelines and cost targets. Simple, robust design solved both of these issues. High production volume makes ease of assembly critical. Transfer to manufacturing during the Covid pandemic led to it’s own unique challenges.
Results
Cost savings vs previous model of roughly 50%. Huge improvement in scrap rate. Improved user interface.
