Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wearable devices, such as smart watches and bracelets, often get lost due to users forgetting to retrieve them after removal, especially in public places or when the battery power is low.

Innovation Solution

A method and apparatus that determine whether a wearable device is worn by a user, obtain usage status information, and send a notification when predefined conditions are met, such as being in a public place or having low battery, to remind the user and prevent loss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the wearable device is taken off for various reasons, then the user's convenience is improved, but the device may be lost

Engineering Contradiction:

Improveconvenience of removing wearable deviceVSAvoidrisk of device loss

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection to determine whether the wearable device is worn before the user actually loses it. By detecting wear state changes in advance and sending notifications proactively, the system allows users to retrieve the device before it is misplaced, thus preventing loss while maintaining removal convenience

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop by continuously monitoring wear state and sending notifications to users when the device is detected as unworn. This feedback mechanism informs users of the device's status, enabling them to take corrective action and prevent loss while maintaining the freedom to remove the device when needed

Inventive Principle:

Principle #23Feedback

2Reliability

If the wearable device is monitored continuously to detect loss, then the reliability is improved, but the energy consumption increases

Engineering Contradiction:

Improvedevice loss detection capabilityVSAvoidenergy consumption of wearable device

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous monitoring, the system uses periodic detection by checking wear state at intervals or at specific trigger points (such as when the device is removed). This periodic approach maintains adequate detection capability while significantly reducing energy consumption compared to continuous monitoring

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The wearable device leverages its existing sensors and processing capabilities to autonomously detect its own wear state and generate notifications. This self-service approach eliminates the need for additional dedicated monitoring hardware and reduces overall system energy requirements while maintaining reliable loss detection

Inventive Principle:

Principle #25Self-service

AI summary

A method for providing a notification, includes: determining whether a wearable device is worn by a user; obtaining usage status information of the wearable device when the wearable device is unworn by the user; determining whether to send the notification based on the usage status information of the wearable device; and sending the notification when a predefined condition is met.
