Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
UAVs are insufficiently protected against powerful electromagnetic fields, particularly near high or very high voltage lines, where they can be vulnerable to electric arcs and interference, compromising their stability and precision.
Innovation Solution
The design incorporates an electrically conductive strip around the structural elements of motorized propellers and a conductive housing to provide both mechanical and electromagnetic protection, ensuring the UAV's components are shielded from intense electromagnetic fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the UAV uses standard mechanical protection for propellers, then maneuverability and responsiveness are improved, but vulnerability to electric arcs and electromagnetic fields increases
Solution Approach 1:
The patent applies composite materials by combining mechanical protection elements with electromagnetic shielding materials. The conductive coating is applied to the mechanical protection structural elements, creating a composite structure that provides both mechanical protection and electromagnetic shielding functionality in a single integrated component.
Solution Approach 2:
The conductive coating acts as an intermediary layer between the mechanical protection structural element and the external electromagnetic environment. This intermediate layer deflects electric arcs and shields the internal components from electromagnetic fields while maintaining the mechanical protection function.
2Adaptability or versatility
If the UAV approaches high voltage lines for monitoring, then application value is improved, but exposure to powerful electromagnetic fields and electric arcs increases
Solution Approach 1:
The patent converts the potentially harmful electromagnetic fields and electric arcs into a beneficial shielding effect. The conductive coating on the mechanical protection elements acts as a Faraday cage, using the same electromagnetic fields that pose a threat to deflect and redirect them away from sensitive internal components.
Solution Approach 2:
The conductive coating provides preliminary protection by deflecting electric arcs before they can reach internal components. The coating is positioned on the outer surface of mechanical protection elements, creating a first line of defense against electromagnetic hazards before the UAV's components are exposed.
3Reliability
If the UAV incorporates conductive shielding around propellers, then protection against electromagnetic fields is improved, but device complexity increases
Solution Approach 1:
The patent merges the mechanical protection function and electromagnetic shielding function into a single integrated structure. The conductive coating is applied directly to the mechanical protection structural elements, combining two protective functions into one component rather than adding separate shielding structures.
Solution Approach 2:
The mechanical protection structural elements serve multiple functions: they provide mechanical protection for the propellers and simultaneously serve as electromagnetic shielding structures through the conductive coating. This multi-functionality reduces the need for additional separate components.
