Background

Engineering Context

A product can meet its immediate performance goal while creating hidden environmental or social impacts during material extraction, manufacturing, use, maintenance, or disposal.

Objectives

What You Will Practice

  • Use life-cycle thinking
  • Identify impacts across product stages
  • Distinguish evidence from assumptions
  • Recommend feasible design changes
Materials

What You Need

  • Research access
  • Life-cycle map template
  • Engineering notebook
  • At least three credible sources
Procedure

Instructions

  1. Choose an approved product such as a drone battery, aircraft seat component, composite panel, satellite enclosure, or rocket packaging.
  2. Define the product function and expected service life.
  3. Map raw materials, processing, manufacturing, transportation, use, maintenance, and end-of-life.
  4. For each stage, identify energy, material, waste, emissions, safety, or labor considerations.
  5. Mark the three stages with the greatest likely impact and support the choice with evidence.
  6. Generate four improvement ideas.
  7. Evaluate ideas for impact reduction, technical feasibility, cost, and possible unintended consequences.
  8. Recommend two improvements and identify how success would be measured.
Requirements

Engineering Requirements

  • Include every major life-cycle stage
  • Use at least three credible sources
  • Identify at least three impact categories
  • Recommend two feasible improvements
  • Include one unintended consequence or tradeoff
Constraints

Constraints & Safety

  • Do not claim precise environmental numbers without a valid source
  • Keep the scope clear and manageable
  • Use respectful language when discussing labor or community impacts
Deliverables

What You Submit

  • Life-cycle map
  • Source list
  • Impact hotspot analysis
  • Four improvement ideas
  • Two recommendations with metrics
  • Tradeoff statement
Reflection

Reflection Questions

  1. Which life-cycle stage was easiest to overlook?
  2. Which recommendation had the best impact-to-feasibility balance?
  3. What assumption most affected your analysis?
  4. How could product life be extended?
