Solution Overview

Problem

Existing UWB tag devices require manual association and dissociation with objects, which is tedious and time-consuming, and may result in incorrect mapping if not done properly, defeating the purpose of tracking.

Innovation Solution

An electronic device dynamically associates or dissociates UWB tags with objects based on distance, angle, and association time, using a UWB tag management controller that includes a data monitoring and analysis controller, tag-object correlation controller, and object association management controller to automate the process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual association and dissociation of UWB tags with objects is implemented, then the tag device can be mapped to objects, but the process becomes tedious and time-consuming

Engineering Contradiction:
Improvemapping accuracyVSAvoidsetup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system automatically performs tag-object association and dissociation without requiring manual user intervention. The electronic device monitors UWB signals, determines proximity based on distance and angle parameters, and automatically updates the mapping between tags and objects, allowing the system to serve itself rather than requiring continuous manual configuration

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The electronic device continuously monitors and pre-processes UWB signal data in the background, maintaining readiness to automatically associate or dissociate tags as objects enter or leave proximity zones. This preliminary monitoring and pre-computation of association parameters eliminates the need for manual setup when tagging new objects

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual association of UWB tags with objects is performed, then the tag device can track objects, but the process is tedious and may result in incorrect mapping

Engineering Contradiction:
Improvetracking accuracyVSAvoidoperational simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system continuously monitors UWB signal parameters including distance and angle, providing real-time feedback on object proximity. Based on this feedback, the electronic device automatically adjusts tag-object associations, ensuring accurate tracking while eliminating manual configuration errors. The feedback loop verifies correct mapping by checking whether objects remain within defined proximity thresholds

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical association operations with automated electronic signal processing. Instead of requiring users to physically configure tag mappings, the system uses UWB radio signals to automatically detect object proximity and perform associations, substituting electronic automation for manual mechanical operations

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If automatic dynamic association of UWB tags with objects is implemented, then manual intervention is eliminated, but system complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The electronic device performs multiple functions including UWB signal reception, distance and angle calculation, object identification, and automatic association management within a single integrated system. This multi-functionality consolidates what could be separate complex components into one universal device, reducing overall system complexity while maintaining automated capabilities

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

Solution Approach 2:

The patent combines signal processing, proximity determination, and tag-object mapping functions into a single integrated electronic device. By merging these functions rather than implementing them as separate systems, the solution reduces complexity while achieving automatic dynamic association

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method for dynamically associating an ultra wide band (UWB) tag with an object by an electronic device is provided. The method includes monitoring, by the electronic device, a first object and a second object in vicinity of the UWB tag over a period of time and determining, by the electronic device, a parameter associated with each of the first object and the second object with respect to the UWB tag. Further, the method includes generating, by the electronic device, a correlation between the UWB tag and each of the first object and the second object based on the parameter and dynamically associating, by the electronic device, the UWB tag with one of the first object and the second object based on the correlation between the UWB tag and each of the first object and the second object.
