Solution Overview

Problem

Existing radio positioning support systems face challenges in maintaining accurate indoor positioning due to variations in radio signal coverage caused by changes in the environment, such as changes in beacon positions, interference, or hardware failures.

Innovation Solution

A method that involves receiving observation reports from radio positioning support devices, determining if a predetermined positioning criterion is met, and if not, partially reconfiguring the system by adjusting transmission parameters or determining the need for additional beacons to ensure optimal signal coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If radio positioning support devices are deployed in a fixed configuration, then initial positioning coverage is established, but the system cannot adapt to environmental changes such as beacon position shifts, interference, or hardware failures

Engineering Contradiction:
Improvesystem adaptability to environmental changesVSAvoidsystem reconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements a feedback mechanism where observation reports containing signal strength measurements and device identifiers are continuously collected from mobile devices. These observations are processed to determine current positioning quality, and based on this feedback, the system automatically reconfigures transmission parameters or beacon positions to maintain optimal positioning performance despite environmental changes

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system transitions from a static beacon configuration to a dynamic one where transmission parameters (power, bandwidth, modulation) and beacon positions can be adjusted in real-time based on observed positioning quality. This allows the system to adapt to changing environmental conditions while maintaining positioning accuracy

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the system continuously monitors and reconfigures to maintain positioning accuracy, then positioning quality is preserved, but system complexity and resource consumption increase

Engineering Contradiction:
Improvepositioning accuracyVSAvoidmonitoring and reconfiguration system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system maintains positioning accuracy by dynamically adjusting transmission parameters such as power levels, bandwidth, and modulation schemes based on observed signal conditions. These parameter changes allow the system to compensate for environmental variations without requiring complete system reconfiguration, thereby managing complexity while preserving measurement precision

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If observation reports are collected from all radio positioning support devices, then comprehensive coverage information is obtained, but data processing load and system overhead increase

Engineering Contradiction:
Improvecoverage information completenessVSAvoiddata processing efficiency
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The system collects observation reports from radio positioning support devices selectively rather than universally. By processing reports only from devices that provide valuable coverage information or exhibit anomalous behavior, the system obtains sufficient coverage data while reducing the overall data processing load and system overhead

Inventive Principle:
Principle #16Partial or excessive action
