Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If kinetic or chemical energy is used to destroy enemy radars, then radar destruction capability is improved, but permanent damage to the radar is caused

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent replaces mechanical/chemical destruction systems with an electromagnetic field-based disruption system. Instead of using kinetic impact or chemical warheads to physically destroy the radar, the invention uses an electromagnetic-sensitive fluid that generates disruptive electromagnetic fields when applied to the radar surface, thereby substituting mechanical destruction with electromagnetic interference.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electromagnetic-sensitive fluid acts as an intermediary substance between the disruption device and the radar system. The fluid is delivered to the radar surface and serves as the active agent that generates electromagnetic disruption, mediating the interaction between the delivery mechanism and the target radar without requiring direct mechanical contact or chemical destruction.

Inventive Principle:
Principle #24Intermediary (Mediator)
