Solution Overview

Problem

Heritage point-to-point communications systems face limitations in transmitting high data rates over long distances due to signal strength decay and the inability to establish multi-user connections, as they rely on omni-directional radio systems that require accurate pointing, acquisition, and tracking (PAT) for effective communication.

Innovation Solution

A networked communications system comprising multiple communications elements, including devices and a node, each equipped with a PAT module for establishing and maintaining PAT links, enabling the formation of multiple inter-device connections through a communications node to ensure accurate data transmission and tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If omni-directional radio systems are used for point-to-point communications, then system simplicity is maintained, but data transmission rate and communication range are limited due to signal strength decay

Engineering Contradiction:
Improvesystem simplicityVSAvoiddata transmission rate
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent replaces traditional mechanical omni-directional radio systems with an optical communication system that uses directed beams. This substitution enables higher data transmission rates through optical carriers while maintaining system manageability through automated PAT (Pointing, Acquisition, and Tracking) mechanisms, resolving the contradiction between simplicity and productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental transmission parameter from radio frequency omni-directional broadcasting to optical frequency directed beams. This parameter change enables significantly higher data rates over long distances by utilizing optical carriers that can maintain signal strength through precise beam directionality, overcoming the signal decay limitation of traditional radio systems.

Inventive Principle:
Principle #35Parameter changes

2Area of stationary object

If omni-directional radio systems broadcast into large hemispheres, then coverage area is increased, but multi-user connectivity is not enabled due to signal strength fall-off

Engineering Contradiction:
Improvecoverage areaVSAvoidmulti-user connectivity
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent segments the coverage area into multiple directed optical beams rather than using a single omni-directional broadcast. Each beam can be independently controlled and assigned to different users, enabling multi-user connectivity while maintaining precise signal delivery. This segmentation allows the system to serve multiple users simultaneously without the signal strength fall-off problem of omni-directional systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic PAT (Pointing, Acquisition, and Tracking) capabilities that allow the optical beams to be dynamically directed and adjusted in real-time. This dynamic control enables the system to adapt to different user positions and maintain optimal signal strength for multiple users simultaneously, transforming the static omni-directional broadcast into a dynamic multi-user communication system.

Inventive Principle:
Principle #15Dynamics

3Productivity

If optical systems are used for higher data rates, then carrier frequency is increased, but accurate PAT is required to maintain informational contact

Engineering Contradiction:
Improvedata rateVSAvoidPAT accuracy requirement
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-service PAT capabilities where the optical communication system automatically performs pointing, acquisition, and tracking without requiring complex manual intervention. The system uses feedback mechanisms and automated control to maintain accurate beam alignment, enabling high data rates through optical carriers while managing the PAT complexity through self-correcting mechanisms that continuously adjust for maintaining informational contact.

Inventive Principle:
Principle #25Self-service
