Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Portable electronic devices often miss notifications when left unattended during charging or syncing, leading to missed information and potential privacy issues due to unobserved alerts.

Innovation Solution

A system that queues notifications while the device is in communication with a second electronic device and plays audible alerts upon termination of this communication, ensuring the user is informed of received information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the device is left unattended during charging or syncing, then the communication function is maintained, but notifications are missed and information delivery reliability deteriorates

Engineering Contradiction:

Improvenotification delivery reliabilityVSAvoiduser attention requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary action by detecting when the device is unattended and proactively playing audible notifications before the user returns. The notification queue accumulates notifications during unattended periods, and the system automatically alerts the user upon device retrieval, eliminating the need for continuous user monitoring.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring device status (attended vs. unattended) and adjusting notification behavior accordingly. When the device is detected as unattended, the system queues notifications; when attended, it plays them. This closed-loop feedback ensures notifications are delivered at the optimal moment for user awareness.

Inventive Principle:

Principle #23Feedback

2Reliability

If notifications are played immediately upon receipt, then information is delivered promptly, but privacy is compromised in public spaces

Engineering Contradiction:

Improveinformation delivery timelinessVSAvoidprivacy exposure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system queues notifications in advance during unattended periods without playing them immediately. This preliminary accumulation allows the system to delay notification playback until the device is attended and the user is present, ensuring timely delivery without premature public exposure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The notification playback behavior dynamically adapts based on device status. When unattended, notifications are queued silently; when attended, they are played audibly. This dynamic adjustment balances timely information delivery with privacy protection in public spaces.

Inventive Principle:

Principle #15Dynamics

3Reliability

If the device continuously monitors for notifications, then notification detection is reliable, but energy consumption increases

Engineering Contradiction:

Improvenotification detection accuracyVSAvoiddevice energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system uses periodic status checks (attended vs. unattended) rather than continuous monitoring. The notification queue operates periodically, accumulating notifications during unattended periods and playing them during attended periods. This periodic approach maintains detection reliability while reducing energy consumption compared to continuous active monitoring.

Inventive Principle:

Principle #19Periodic action

AI summary

A method of alerting a user to information includes receiving a notification while a portable electronic device is in communication with a second electronic device, queueing the notification, terminating the communication between the portable electronic device and the second electronic device, and playing an audible alert of the notification after terminating the communication.
