Solution Overview

Problem

Current mobile communication systems fail to optimize transceiving parameters in real-time based on terrain and line-of-sight information, leading to inefficiencies and poor data service due to inadequate adaptation to topographical conditions.

Innovation Solution

A position-based interleave regulation system that utilizes a GPS receiver, RF transceiver, and GIS database to optimize transceiving parameters, such as interleave length, channel coding, and modulation modes, based on device positions and topographical data, reducing the need for inefficient ACK/NAK protocols and minimizing channel resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If permanently assigned interleave, channel coding, and modulation configurations are used, then device complexity is reduced, but adaptability to varying topographical conditions deteriorates

Engineering Contradiction:

Improveconfiguration managementVSAvoidadaptation to topographical conditions

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic adaptation by allowing mobile devices to automatically adjust interleave, channel coding, and modulation configurations based on real-time channel quality measurements and topographical data from GPS and GIS databases, transforming static configurations into dynamically adaptable ones

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system enables mobile devices to self-optimize their transmission parameters by automatically measuring channel quality, retrieving topographical data, and selecting appropriate configurations without requiring manual intervention or complex network coordination

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If adaptive interleave and channel coding mechanisms are implemented, then adaptability to channel conditions is improved, but device complexity increases

Engineering Contradiction:

Improveadaptability to channel conditionsVSAvoidtransparameter optimization

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary actions by pre-fetching topographical data from GIS databases based on GPS location information before transmission occurs, allowing the device to prepare optimal configurations in advance rather than calculating them in real-time during transmission

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces topographical data from GIS databases as an intermediary that correlates with channel conditions, allowing the device to select configurations based on pre-stored terrain information rather than directly measuring and responding to instantaneous channel variations

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If standard error detection and correction methods are used, then implementation simplicity is maintained, but data service quality deteriorates in varying terrain

Engineering Contradiction:

Improveimplementation simplicityVSAvoiddata service quality

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent changes key transmission parameters (interleave length, channel coding rate, modulation order) based on topographical conditions and channel quality measurements, allowing the system to adapt error correction capabilities to match actual transmission conditions rather than using fixed standard methods

Inventive Principle:

Principle #35Parameter changes

4Reliability

If real-time optimization of transceiving parameters is implemented, then data integrity is improved, but channel resource usage increases

Engineering Contradiction:

Improvedata integrityVSAvoidchannel resource usage

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies partial optimization by focusing only on the most critical transmission parameters that have the greatest impact on data integrity, rather than optimizing all possible parameters, thereby achieving improved reliability with minimal additional channel resource consumption

Inventive Principle:

Principle #16Partial or excessive action
