The Industry Problem
Carbonated beverages lose dissolved \( \text{CO}_2 \) during storage, transit, and repeated opening due to gas permeation, headspace volume expansion, and temperature swings.
Your Mission: Design a smart packaging prototype that actively or passively sustains carbonation (\( \text{CO}_2 \) retention) and optimal product quality from warehouse to final sip.
1. Project Criteria & Constraints
Define the performance requirements (success metrics) and project limitations (boundaries) for your smart container.
Design Criteria (Must-Haves) E.g., pressure seal, insulation
Identify 3 critical performance criteria your smart bottle/can must achieve:
C1
C2
C3
Project Constraints (Limitations) E.g., cost, weight, food-safe
Specify 3 real-world restrictions you must design within:
R1
R2
R3
2. STEAM Integration Matrix
How does your prototype incorporate each discipline?
Science
Henry's Law, gas diffusion, thermal transfer
Technology
Freshness sensors, smart indicators, nano-barriers
Engineering
