Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical equipment remains connected to the power grid for normal operation, then productivity and reliability of power supply are improved, but vulnerability to electromagnetic damage increases
Solution Approach 1:
The system applies preliminary anti-action by detecting electromagnetic field signatures that precede harmful EMP events and triggering disconnection before the actual damage occurs. The detector circuit monitors for characteristic field patterns, and when detected, the controller actuates circuit breakers to disconnect equipment in advance, preventing the harmful electromagnetic effects from damaging the electrical components.
Solution Approach 2:
The system performs preliminary action by continuously monitoring electromagnetic fields and preparing disconnection mechanisms in advance. The detector and controller are positioned and configured beforehand, and upon detecting precursor signals, the system executes disconnection before the harmful event impacts the equipment, ensuring protection is already in place when needed.
2Speed
If disconnection action is delayed until electromagnetic event impacts equipment, then response time is reduced, but damage prevention effectiveness deteriorates
Solution Approach 1:
The system achieves fast response by detecting precursor electromagnetic field signatures that occur before the harmful EMP event fully develops. By identifying these early indicators and triggering disconnection immediately upon detection, the system responds rapidly while still preventing damage, as the actual harmful event has not yet impacted the equipment.
Solution Approach 2:
The system uses feedback from the detector circuit that continuously monitors electromagnetic field conditions. When the detector identifies characteristic field patterns indicating an impending harmful event, this feedback triggers the controller to execute disconnection, creating a closed-loop response system that adapts to real-time electromagnetic conditions.
3Ease of manufacture
If detector and controller are positioned outside shielded enclosure for ease of installation, then ease of manufacture is improved, but susceptibility to electromagnetic interference worsens
Solution Approach 1:
The system applies nesting by placing the controller within a shielded enclosure that protects it from electromagnetic interference. The detector circuit is positioned to monitor external fields while the controller, which processes signals and triggers disconnection, is nested inside the protective enclosure, creating a hierarchical protection structure.
Solution Approach 2:
The shielded enclosure acts as an intermediary between the external electromagnetic environment and the sensitive controller circuitry. It mediates the interaction by blocking harmful electromagnetic fields from reaching the controller while allowing the system to function normally, thus protecting the control system without preventing its operation.
