Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If excess energy is transferred back to the primary energy source, then energy waste is reduced, but negative pricing costs are incurred
Solution Approach 1:
The system performs preliminary actions by storing excess energy in the energy storage device before it can be wasted or cause negative pricing issues. The controller proactively manages energy flow by directing surplus energy from the secondary source to the storage device, preventing the harmful effects of energy waste and negative pricing costs before they occur.
2Productivity
If real-time energy management is implemented, then energy efficiency is improved, but system complexity increases
Solution Approach 1:
The controller serves multiple functions within a single device: it monitors energy production from secondary sources, tracks energy consumption by loads, determines excess energy conditions, and manages energy flow to both loads and storage devices. This multi-functionality improves energy efficiency while minimizing the increase in system complexity by consolidating control functions.
Solution Approach 2:
The system performs self-service through automated controller operations that continuously monitor energy parameters and automatically adjust energy distribution without external intervention. The controller independently determines when excess energy exists and directs it appropriately, enabling real-time energy management while reducing the operational complexity burden on users.
