Solution Overview

Problem

Existing antenna support devices struggle to maintain accurate positioning on non-planar and dynamically changing surfaces, such as oceans and seas, leading to transmission errors and interruptions due to disparities in surface relief caused by meteorological conditions.

Innovation Solution

A floating antenna support device comprising interconnected floating elements with a fixing system, an anchoring element, and an articulated mechanical support that adjusts to maintain a horizontal positioning of the antenna support surface, ensuring continuous and reliable data transmissions by deforming to match the surface relief.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the antenna is mounted on a vessel to maintain line of sight with satellites, then transmission capability is improved, but positioning accuracy deteriorates due to surface relief variations causing incorrect antenna positioning relative to transmission beams

Engineering Contradiction:
Improvetransmission capabilityVSAvoidantenna positioning accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent employs a dynamic positioning system that continuously adjusts the antenna's position and orientation in real-time to compensate for vessel motion and surface relief variations. The antenna mounting structure includes active control mechanisms that respond to sensor feedback, maintaining correct alignment with satellite transmission beams despite changing environmental conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates sensors (accelerometers, gyroscopes, position sensors) that provide continuous feedback about the antenna's position, orientation, and environmental conditions. This feedback is processed by a control system that automatically adjusts antenna positioning to maintain accurate alignment with satellites, resolving the contradiction between transmission reliability and positioning precision.

Inventive Principle:
Principle #23Feedback

2Device complexity

If a fixed antenna support structure is used on a floating device, then device complexity is reduced, but transmission reliability deteriorates due to inability to maintain horizontal alignment on non-planar surfaces

Engineering Contradiction:
Improvesupport structure complexityVSAvoidtransmission reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

Instead of a completely fixed structure, the patent uses a semi-rigid support structure with controlled degrees of freedom. The structure includes mechanical elements (gimbals, adjustment mechanisms) that allow the antenna to maintain horizontal alignment while keeping the overall device design relatively simple and avoiding over-engineering.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the floating device deforms to match surface relief, then adaptability to non-planar surfaces is improved, but antenna positioning stability deteriorates

Engineering Contradiction:
Improvesurface adaptation capabilityVSAvoidantenna positioning stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The floating device is divided into multiple independent floating elements or modular sections that can deform independently to match surface relief. The antenna is mounted on a separate stabilized platform that decouples the deformation of the floating structure from the antenna's positioning, allowing surface adaptation while maintaining positioning stability through active control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary stabilized platform or mechanical isolation system between the deforming floating structure and the antenna. This intermediary element absorbs the deformations and movements of the floating device, providing a stable mounting surface for the antenna that maintains positioning stability even as the underlying floating structure adapts to surface relief variations.

Inventive Principle:
Principle #24Intermediary (Mediator)
