Innovation Solution

A method and device that enable a mobile terminal to automatically perform closed positioning by determining the corresponding closed space based on open space location, acquiring necessary map data and programs from dedicated servers, and integrating them for accurate positioning without user-driven selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual user intervention is required to select and install positioning programs, then positioning accuracy can be maintained, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improvepositioning accuracyVSAvoiduser operation complexity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The terminal automatically performs closed positioning without requiring user intervention to select or install positioning programs. The system self-services by autonomously determining the terminal's location in closed space and executing the appropriate positioning algorithm, thereby eliminating manual operations while maintaining positioning accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The terminal pre-acquires positioning programs and map data for multiple closed spaces before actual positioning is needed. When the terminal enters a closed space, the appropriate positioning program is already available for immediate execution, eliminating the need for manual selection and installation during the positioning process.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If multiple closed positioning programs are installed for different closed spaces, then positioning accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The terminal employs a unified positioning system that can automatically adapt to different closed spaces. Instead of requiring separate dedicated programs for each closed space, the system uses a universal positioning framework that selects and executes the appropriate positioning algorithm based on the detected closed space, thereby reducing the number of installed programs while maintaining positioning accuracy across diverse environments.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The terminal pre-acquires positioning programs and map data for multiple closed spaces and stores them locally. This preliminary preparation eliminates the need for manual installation during operation, reducing system complexity by having all necessary components readily available without requiring complex installation management.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If automatic closed positioning is implemented, then ease of operation is improved, but reliability may deteriorate due to automated selection errors

Engineering Contradiction:
Improveautomation levelVSAvoidpositioning reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The automatic closed positioning system incorporates feedback mechanisms to verify the correctness of automated program selection. The terminal continuously monitors positioning results and environmental characteristics, comparing them against expected patterns to confirm that the selected positioning program is appropriate. This feedback loop ensures reliability by detecting and correcting potential selection errors automatically.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The terminal performs preliminary verification of the selected positioning program against the detected closed space characteristics before execution. By pre-checking compatibility between the identified closed space and the selected positioning program, the system ensures reliable operation while maintaining automation, preventing erroneous program selection before it can affect positioning accuracy.

Inventive Principle:
Principle #10Preliminary action
