Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wearable devices such as smartwatches and fitness trackers are often misplaced or intentionally removed, leading to frustration and reduced effectiveness due to inadequate non-use notifications, especially when the device is not in contact with the user's body.

Innovation Solution

A system and method using sensors, location modules, and radio components to determine if a wearable device is not in use, providing non-use indications to associated UEs, enhancing accuracy and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If wearable devices provide basic functionality without non-use detection, then device simplicity is maintained, but user awareness of device non-use is insufficient leading to misplacement

Engineering Contradiction:

Improveuser awareness of device non-useVSAvoiddevice functionality

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The wearable device autonomously monitors its own usage status through sensors and automatically generates notifications when non-use is detected, eliminating the need for manual user input or external monitoring systems

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides real-time feedback to the user through notifications when the device is detected as not being worn, enabling users to take corrective action to prevent misplacement

Inventive Principle:

Principle #23Feedback

2Measurement precision

If sensors and location modules are added to detect non-use, then detection accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvenon-use detection accuracyVSAvoiddevice structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

Existing sensors in the wearable device (accelerometers, gyroscopes, location modules) that were originally designed for fitness tracking and navigation are repurposed to detect non-use conditions, eliminating the need for dedicated detection hardware

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device uses its own existing sensor suite to monitor its operational status and generate alerts, making the detection system self-contained and eliminating additional hardware requirements

Inventive Principle:

Principle #25Self-service

3Reliability

If continuous monitoring is implemented to detect non-use, then detection reliability is improved, but energy consumption increases

Engineering Contradiction:

Improvenon-use detection reliabilityVSAvoiddevice power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous monitoring, the system periodically checks usage status at predetermined intervals, significantly reducing power consumption while maintaining reliable detection capability

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system monitors only the essential parameters needed to determine non-use (motion, location, contact status) rather than all possible sensor data, achieving reliable detection with minimal energy expenditure

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Embodiments of the present disclosure are directed to monitoring utilization of a user equipment (UE). Wearable UEs, typically having small form factors, are easily forgotten once removed. Using one or more sensors of the wearable UE, a non-use determination can be made that allows the wearable UE to notify a second, affiliated UE about its non-use. In some aspects, usage patterns or divergent usage of the wearable UE and affiliated UE are used to validate non-use determinations before causing a notification to be delivered on the affiliated UE.
