Solution Overview

Problem

Current communication applications lack the ability for participants to exit conference calls gracefully, leading to situations where participants may feel trapped in prolonged calls due to social etiquette concerns or differing levels of engagement.

Innovation Solution

Implementing a call exit controller that enables smart call exit functionality between connected devices, allowing users to exit conference calls gracefully by sharing audio content and using contextual messages with cloned voices to politely conclude the call.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If users directly exit a conference call, then they can end the call efficiently, but they may appear rude to other participants

Engineering Contradiction:
Improvecall exit efficiencyVSAvoidsocial etiquette violation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by automatically generating and playing polite exit messages before the user actually leaves the call. The controller detects call duration and participant count, then proactively creates contextual exit scripts that explain the departure reason, allowing the user to exit gracefully without directly hanging up on others.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary system (the call exit controller) that mediates between the user's desire to leave and the social etiquette requirements. This intermediary generates polite exit messages that bridge the gap between efficient call termination and maintaining good relationships with other participants.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the call exit controller generates personalized exit messages, then social etiquette is maintained, but device complexity increases

Engineering Contradiction:
Improvesocial etiquette maintenanceVSAvoidcall exit controller functionality
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system uses copying by generating template-based exit messages that can be reused across different calls. Instead of creating entirely new messages each time, the controller selects from pre-defined templates and customizes them with call-specific parameters (duration, participant count), reducing the complexity of message generation while maintaining personalization.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent applies parameter changes by varying message content based on detectable call parameters such as call duration and number of participants. The controller adjusts the exit message tone and content based on these parameters, providing contextual appropriateness without requiring complex decision-making logic.

Inventive Principle:
Principle #35Parameter changes

3Loss of time

If the system monitors call duration and participant engagement, then graceful exit timing is optimized, but loss of information about call context increases

Engineering Contradiction:
Improveprolonged call durationVSAvoidcall context understanding
Core Design Contradiction:
Loss of timeVSLoss of information

Solution Approach 1:

The system implements feedback by continuously monitoring call parameters (duration, participant activity) and using this information to determine the appropriate exit timing and message content. The controller receives feedback from the call state and adjusts its exit strategy accordingly, ensuring the user leaves at an optimal time while maintaining context awareness.

Inventive Principle:
Principle #23Feedback

AI summary

In aspects of call exit management between connected devices, a mobile wireless device detects, via a computing device communicatively linked to a mobile wireless device, that a user desires to exit a conference call session on the computing device; displays, on a display device of the computing device, a prompt including at least one contextual transcript; sends, to the mobile wireless device and based on input relative to the prompt, a selected contextual transcript from the at least one contextual transcript, the mobile wireless device generating a cloned audio message from the selected contextual transcript; and sends the cloned audio message to an external speaker that emits the cloned audio message.
