Engineer as a Problem Solver

Engineering Method

  • Phases (in sequence):
    • Phase 1: Idea
    • Phase 2: Concept
    • Phase 3: Planning
    • Phase 4: Design
    • Phase 5: Development
    • Phase 6: Launch
  • Key activities associated with each phase (as depicted):
    • Define objectives and identify existing objectives
    • Identify problem and potential solutions
    • Plan: determine requirements, constraints; develop program and drawings
    • Create schematics, models, and algorithms
    • Develop prototypes and conduct experiments; collect results
    • Validation and verification; build proof of concept
    • Construct and test; analyze data
    • Communicate results; finalize conclusions
  • Supporting concepts (from the slide):
    • Question background; a hypothesis; research; the scientific method

The Engineering Design Process (Overview)

  • The design process is a series of steps engineers follow to find a solution to a problem.
  • Steps commonly include:
    • Determine objectives and constraints
    • Prototyping
    • Testing and evaluation
    • Iterative refinement of the solution

Engineering Design Process Steps

  • Identify the problem
  • Brainstorm solutions
  • Select a design
  • Build a model or prototype
  • Test and evaluate
  • Optimize the design
  • Share the solution

Engineer as a Change Agent

  • A change agent is someone who:
    • Identifies areas for improvement
    • Initiates innovation
    • Implements new solutions
    • Influences others toward positive transformation

Key Aspects of Engineers as Change Agents

  • Engineers introduce new technologies (e.g., AI, renewable energy, electric vehicles)
  • Example: Electrical engineers helped shift from fossil fuels to solar and wind power, transforming the energy sector

2. Solving Societal Challenges

  • Engineers design systems to solve global issues like clean water, climate change, healthcare access
  • Example: Engineers Without Borders designs low-cost water purification systems in rural areas

3. Sustainable Development

  • Engineers promote eco-friendly designs and sustainable practices
  • Example: Green buildings, biodegradable materials, energy-efficient transport systems

4. Economic Growth

  • By developing efficient products and systems, engineers boost productivity and economic development
  • Example: Automation in manufacturing has revolutionized global supply chains

5. Digital Innovation

  • Engineers are central to the digital revolution, creating smart systems and AI-based solutions
  • Example: Software engineers developing health apps that monitor and predict disease

6. Disaster Management & Recovery

  • Engineers help design systems for early warning, rescue operations, and rebuilding
  • Example: Structural engineers redesign buildings to be earthquake-resistant

Connections to Core Principles

  • Professional ethics and accountability underpin all attributes and functions.
  • Systems thinking and interdisciplinary collaboration are essential for design, optimization, and implementation.
  • Sustainability and societal impact are integral to project decisions.
  • Lifecycle perspective (from concept to maintenance) aligns with long-term resilience and value creation.

Practical Implications and Real-World Relevance

  • Licensure (PE) can enable public-facing engineering services and oversight.
  • Technical proficiency must be paired with communication and teamwork to deliver complex solutions.
  • Change agents drive not only technical improvements but also organizational and policy-related progress.
