Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lightning strike occurs on the flying object, then the current passes through the airframe and reaches the ground, but the flying object becomes inoperable and may crash
Solution Approach 1:
The patent introduces a conductor lattice as an intermediary structure between the flying object and the lightning strike. The lattice is positioned around the flying object at a distance that does not hinder flight, serving as a mediator to intercept and redirect lightning current away from the airframe, thus protecting the flying object while maintaining its operational reliability
Solution Approach 2:
The conductor is divided into a lattice structure with multiple segments arranged in a grid pattern. This segmentation allows the conductor to effectively intercept lightning strikes from various directions and distribute the current across multiple paths, enhancing protection while maintaining flexibility in positioning around the flying object
2Object-affected harmful factors
If a conductor is placed close to the flying object to protect it, then protection effectiveness increases, but flight may be hindered
Solution Approach 1:
The conductor lattice is designed with flexible support structures that allow it to move dynamically with the flying object during flight. The lattice maintains its protective positioning relative to the flying object while adapting to flight movements, ensuring both protection effectiveness and unhindered flight operation
Solution Approach 2:
The conductor is arranged in a three-dimensional lattice structure surrounding the flying object, utilizing spatial dimensions to provide comprehensive protection. This dimensional arrangement allows the conductor to maintain effective protective distances in all directions without interfering with the flying object's operational space
