Solution Overview

Problem

Mobile devices lack an efficient mechanism to automatically manage 'do not disturb' (DND) mode, often requiring manual activation and deactivation, which can lead to interruptions and inconvenience in managing incoming calls during scheduled events or quiet periods.

Innovation Solution

A method and system that automatically activates and deactivates a DND mode based on a user-selected time increment, triggered by receiving a call, using physical or on-screen controls, and communicates this status to the caller and appointment attendees, with options to silence the ringer, direct calls to voicemail, or power off the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual activation and deactivation of DND mode is implemented, then user control over call management is improved, but operation convenience deteriorates due to requiring manual intervention

Engineering Contradiction:
Improveoperation convenienceVSAvoidtime for manual activation and deactivation
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically activating DND mode before the user would need to manually activate it. The mode is triggered automatically upon detecting specific conditions (such as scheduled events or geo-fence entries), eliminating the need for manual activation. Similarly, the system automatically deactivates the mode when the triggering condition ends, performing the deactivation action in advance of when the user would need to manually intervene.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements self-service by autonomously managing the DND mode without requiring user intervention. The mobile device automatically detects triggering conditions, activates DND mode, maintains it for the appropriate duration, and deactivates it when finished. This self-managing system eliminates the need for manual operation while ensuring proper call management during scheduled events or quiet periods.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If automatic DND mode activation is implemented, then interruption reduction is improved, but device complexity increases

Engineering Contradiction:
Improveinterruption reductionVSAvoidautomation mechanism complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system merges the DND mode management functionality with existing mobile device components such as the event calendar system, geo-fence location tracking, and call management infrastructure. By integrating DND activation logic into these existing systems, the patent avoids creating a separate complex automation mechanism. The DND mode leverages the event detection and location services already present in modern smartphones, thereby reducing overall device complexity while achieving automatic interruption reduction.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If DND mode communicates status to caller and appointment attendees, then information completeness is improved, but loss of information increases due to potential communication delays

Engineering Contradiction:
Improveinformation transmission accuracyVSAvoidcommunication delay
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary action by notifying the caller and appointment attendees in advance that DND mode is being activated. Instead of waiting until the mode is fully active before communicating status, the system sends notifications beforehand, allowing recipients to prepare for the upcoming unavailability. This preliminary notification approach ensures information is transmitted accurately without significant delays, as the communication occurs at the moment of mode activation rather than after a delay.

Inventive Principle:
Principle #10Preliminary action

AI summary

A do not disturb (DND) mode for telephonic devices, in which the DND mode is automatically deactivated after a time increment has elapsed, the DND mode having been activated based on detecting, upon receiving a telephone call, a selection of the control.
