Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data connectivity in remote areas is often unreliable and costly due to lack of infrastructure, and ground-level antennas face challenges in transmitting signals to high-altitude balloons due to obstructions and varying balloon positions.
Innovation Solution
A sealed vessel with a liquid and a floating antenna base is used to position the antenna perpendicular to the ground, ensuring stable signal transmission to high-altitude balloons, and a method involving a radiator and reflector configuration with a separation distance to optimize emission patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is mounted on a building or post to achieve stable signal transmission, then the transmission stability is improved, but the alignment precision deteriorates due to obstructions and varying balloon positions
Solution Approach 1:
The patent applies the dynamics principle by making the antenna mounting system movable rather than fixed. The antenna is allowed to float and rotate freely on the liquid surface inside the sealed vessel, enabling it to dynamically adjust its orientation in response to varying balloon positions and maintain optimal alignment without being constrained by fixed mounting structures
Solution Approach 2:
The patent applies the self-service principle by enabling the antenna to automatically self-align with the balloon through buoyant forces and gravitational effects. The floating mechanism allows the antenna to autonomously position itself perpendicular to the liquid surface and orient toward the balloon without requiring external adjustment mechanisms or manual intervention
2Reliability
If the antenna is directed perpendicular to the ground to improve signal transmission to high-altitude balloons, then the transmission effectiveness is improved, but the device complexity increases due to the need for precise positioning mechanisms
Solution Approach 1:
The patent applies the pneumatics and hydraulics principle by using a liquid medium (water or other fluid) as the mounting medium for the antenna. The antenna floats on the liquid surface, and the liquid provides both support and alignment functions, eliminating the need for complex mechanical positioning mechanisms while ensuring the antenna maintains a perpendicular orientation to the ground
Solution Approach 2:
The patent applies the mechanics substitution principle by replacing complex mechanical positioning and alignment mechanisms with a simple floating system based on buoyancy and fluid mechanics. Instead of using motors, gears, or adjustable mounts to achieve precise perpendicular alignment, the system uses the natural properties of floating objects on a liquid surface
