Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a single antenna with limited polarization direction is used, then the device structure is simple, but communication loss increases
Solution Approach 1:
The patent divides the antenna system into multiple antenna elements (first, second, and third antenna elements) with different polarization directions. Each antenna element is configured to receive satellite communication signals from different polarization angles, thereby segmenting the reception function to reduce communication loss while managing structural complexity through modular design
Solution Approach 2:
The patent introduces polarization direction as an additional dimension for signal reception. By configuring antenna elements with different polarization directions (e.g., horizontal, vertical, and slant polarizations), the system captures signals from multiple dimensional orientations, converting a single-direction limitation into a multi-dimensional reception capability that reduces communication loss
2Reliability
If multiple antenna elements with different polarization directions are added, then communication loss is reduced, but device complexity increases
Solution Approach 1:
The patent designs the antenna elements to serve multiple functions: each element not only receives signals in its specific polarization direction but also contributes to the overall diversity reception system. The first, second, and third antenna elements collectively provide both polarization diversity and spatial diversity, making each component multi-functional in enhancing signal reception reliability across different satellite signal conditions
Solution Approach 2:
The patent combines multiple antenna elements with different polarization characteristics into a unified antenna system integrated on the wearable device. By merging these elements with complementary polarization directions, the system achieves enhanced signal reception reliability through diversity combining, where the combined output of multiple elements provides more robust signal capture than any single element alone
3Adaptability or versatility
If antenna elements are arranged in different directions, then signal reception coverage is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent assigns specific polarization directions and positioning characteristics to each antenna element based on its local function within the system. The first antenna element is positioned and oriented for optimal reception in one polarization direction, the second for another direction, and the third for a third direction. This local optimization of each element's position and orientation according to its specific reception role improves overall coverage while managing manufacturing precision through differentiated design specifications
