An electronic device with processing circuitry, memory, and wireless communication capabilities is used to generate management information, identify control scheduling for anchors, control the sequential transmission of ranging signals, receive feedback signals, and update the network topology accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple anchors transmit ranging signals simultaneously, then the positioning service can be provided more quickly, but signal interference occurs and transmission reliability deteriorates

Engineering Contradiction:

Improvepositioning service speedVSAvoidsignal transmission reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements periodic time division multiplexing where anchors transmit ranging signals in sequential time slots rather than simultaneously. The network management device allocates specific time periods for each anchor to transmit and receive feedback signals, creating a periodic transmission pattern that eliminates interference while maintaining efficient positioning service delivery

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent segments the ranging signal transmission process by dividing it into distinct time slots for different anchors. Each anchor is assigned a specific time window for transmission, and the feedback signal reception is also segmented into corresponding time periods. This segmentation prevents signal collision and enables reliable communication among multiple anchors

Inventive Principle:

Principle #1Segmentation

2Productivity

If the network management device controls all anchors centrally, then transmission scheduling is optimized, but system complexity increases

Engineering Contradiction:

Improvetransmission scheduling efficiencyVSAvoidnetwork management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The network management device performs preliminary actions by pre-configuring time division multiplexing parameters, transmission time slots, and feedback reception windows for all anchors before ranging operations begin. This advance planning and configuration enables automated, interference-free scheduling without requiring complex real-time control decisions during actual positioning operations

Inventive Principle:

Principle #10Preliminary action
