Static/DynamicDesign Concepts

• Static design concept
• One that has reached a conceptual plateau
  established in time and has subsequent products
  developed based on it.
• Primarily done in Product Engineering
• Example the automobile
• Dynamic design concept
• Originates from new approaches to existing
  problems or is generated by the necessity to find
  solutions to new problems
• Located towards the innovative end of design
  activity spectrum
• Product development work on dynamic aspects done
  primarily in Advanced Development
