VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple technologies such as wireless communication, base station positioning, and inertial navigation positioning are used to form an indoor positioning system, then positioning coverage is improved, but positioning precision deteriorates

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The wireless energy transmission device is designed to perform both wireless energy transmission and positioning functions simultaneously. By determining N groups of reference transmission parameters from multiple groups of reference transmission parameters according to the transmission parameters, the system achieves precise positioning while maintaining the primary energy transmission function, thus resolving the contradiction between multi-functionality and precision

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the parameter set from using multiple different positioning technologies to using N groups of reference transmission parameters from a single wireless energy transmission system. By selecting and comparing transmission parameters (such as phase, amplitude, frequency) across multiple reference groups, the system achieves high-precision positioning through parameter analysis rather than through multiple technology layers

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If N groups of reference transmission parameters are determined from multiple groups of reference transmission parameters, then positioning accuracy is improved, but calculation complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The system pre-determines and stores multiple groups of reference transmission parameters before actual positioning is needed. During positioning operations, the system only needs to compare current transmission parameters against these pre-established reference groups, significantly reducing real-time calculation complexity while maintaining high positioning accuracy

Inventive Principle:

Solution Approach 2:

Instead of processing all possible transmission parameter combinations, the system selectively determines N groups of reference transmission parameters from the multiple available groups. This partial processing approach balances computational load with positioning precision requirements, avoiding unnecessary calculations while ensuring sufficient accuracy
