Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing low and medium frequency antenna structures is challenging due to their large size and weight, which necessitates a significant amount of conductors or wires, leading to increased weight and complexity.
Innovation Solution
The antenna structure incorporates a varying number of wires along its length, reducing the wire count in sections with lower current density, thereby decreasing the overall weight without compromising performance, and includes a dielectric core for mechanical support and tethering.

Engineering Contradiction Analysis
1Reliability
If a significant amount of conductors or wires is used to achieve low and medium frequency antenna functionality, then the antenna can transmit and receive electromagnetic signals effectively, but the weight and complexity of the antenna structure increases significantly
Solution Approach 1:
The patent applies local quality by varying the wire count along the length of the antenna. Different sections of the antenna have different numbers of wires based on their specific functional requirements. The core sections maintain sufficient wires for electromagnetic signal transmission, while non-critical sections use fewer wires, optimizing the balance between performance and weight.
Solution Approach 2:
The antenna is divided into multiple sections with different wire counts. This segmentation allows each portion to be optimized independently - critical sections have more wires for signal integrity, while less critical sections have fewer wires to reduce weight. The modular approach maintains overall antenna functionality while reducing total material usage.
2Reliability
If a significant amount of conductors or wires is used to achieve low and medium frequency antenna functionality, then the antenna can transmit and receive electromagnetic signals effectively, but the structural complexity of the antenna increases
Solution Approach 1:
The patent implements local quality by assigning different wire counts to different sections of the antenna based on their specific functional needs. This creates a non-uniform structure that is optimized locally - critical sections have more wires for signal transmission, while other sections have fewer wires, reducing overall complexity while maintaining performance.
Solution Approach 2:
The antenna structure is segmented into multiple portions with varying wire counts. This segmentation simplifies the overall design by breaking down the complex uniform structure into manageable sections, each with optimized wire density. The segmented approach reduces manufacturing complexity and structural complexity while preserving antenna functionality.
3Weight of moving object
If the wire count is reduced in sections with lower current density, then the overall weight of the antenna decreases, but maintaining electrical connectivity and performance becomes more challenging
Solution Approach 1:
The patent applies local quality by matching wire count to current density distribution. Sections with high current density maintain sufficient wire counts for electrical connectivity, while sections with lower current density use reduced wire counts. This localized optimization reduces weight without compromising electrical connectivity in critical areas.
Solution Approach 2:
The antenna is segmented into high current density and low current density sections. Each segment is designed with appropriate wire count for its electrical requirements. This segmentation allows weight reduction in low current density areas while maintaining electrical connectivity in high current density areas, resolving the contradiction between weight and connectivity.
