Solution Overview

Problem

The increasing number of devices and objects that individuals need to carry has led to challenges in tracking their proximity, resulting in potential productivity losses due to forgotten or misplaced items.

Innovation Solution

A computer-implemented method and system that determine the proximity of devices and objects within a predefined area, predicting if a device will move outside this area without others, and transmitting alert notifications to ensure that devices remain together.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users carry multiple devices and objects, then functionality and utility increase, but tracking proximity and preventing loss becomes more difficult

Engineering Contradiction:
ImproveutilityVSAvoidtracking complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the tracking task by assigning individual identifiers to each device and object, allowing independent tracking of each item while maintaining overall group proximity management. Each device can be monitored separately through its unique identifier, enabling granular control and tracking of multiple items simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary tracking mechanism that mediates between multiple devices and objects, using proximity detection to monitor their relative positions. This intermediary system provides alert notifications when devices may be left behind, acting as a mediator that manages the complexity of tracking multiple items without requiring direct user intervention for each item.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If real-time proximity monitoring is implemented, then productivity is improved by preventing loss, but energy consumption and system complexity increase

Engineering Contradiction:
ImproveproductivityVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic proximity monitoring rather than continuous monitoring, checking device proximity at intervals and triggering alert notifications only when separation is detected. This periodic action reduces energy consumption compared to continuous monitoring while still maintaining effective productivity protection by alerting users when devices may be left behind.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The tracking system operates autonomously by automatically detecting device proximity, predicting potential separation, and sending alert notifications without requiring active user engagement. This self-service approach maintains productivity benefits while minimizing energy consumption by eliminating the need for continuous user interaction or manual tracking efforts.

Inventive Principle:
Principle #25Self-service

AI summary

Disclosed herein are system, apparatus, article of manufacture, method, and/or computer program product embodiments for tracking proximities of devices and/or objects. In one embodiment, the system operates by determining whether a plurality of devices of a tethered segment are inside or outside a predefined area. The system also operates by determining that a first device of the plurality of devices is outside of the predefined area based at least partially on the determination of whether the plurality of devices are inside or outside the predefined area. The system further operates by transmitting at least one alert notification to at least one device based at least partially on the determination that the first device is outside the predefined area, wherein the alert notification identifies the first device outside the predefined area.
