Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple wireless positioning methods are used to improve positioning accuracy, then positioning precision is improved, but device complexity increases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple wireless positioning methods (LTE downlink positioning, WiFi positioning, and GNSS positioning) into a unified positioning system. The network side integrates these different positioning technologies and performs fusion calculation to obtain comprehensive location information, thereby improving positioning accuracy without requiring the terminal device to independently manage multiple positioning systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The positioning controller is designed with multi-functionality to handle various positioning methods. It can receive positioning measurement requests, coordinate with different access network nodes (eNodeB, WiFi access points), and process measurement results from multiple positioning technologies through a single unified interface, reducing the complexity at the terminal side.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If positioning measurement and information interaction are performed through core network nodes, then positioning coverage is improved, but positioning delay increases

Engineering Contradiction:

Improvepositioning coverageVSAvoidpositioning delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the positioning function by introducing a positioning controller that operates at the access network side rather than requiring all positioning measurements to go through core network nodes. This segmentation allows positioning measurements to be performed locally at the access network, with only necessary location information being transmitted to the core network, thereby reducing delay while maintaining comprehensive coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning controller performs preliminary positioning measurements and calculations at the access network side before information is transmitted to the core network. By performing these actions in advance, the system reduces the overall positioning delay while still utilizing core network resources for final location determination and service coordination.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If a single wireless positioning technology is used to simplify the system, then device complexity is reduced, but positioning accuracy and adaptability are limited

Engineering Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts positioning parameters and methods based on the terminal's location and network conditions. The positioning controller selects appropriate positioning methods and parameters adaptively, switching between different technologies as needed to optimize both accuracy and complexity management.

Inventive Principle:

4Measurement precision

If positioning measurement requests are sent to multiple access network nodes, then positioning accuracy is improved, but information interaction delay increases

Engineering Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the positioning controller receives measurement results from access network nodes and uses this information to optimize subsequent positioning requests. This feedback loop allows for more efficient information interaction and reduced overall delay by avoiding redundant measurements.

Inventive Principle:
