Caller Feedback Mechanism for Mobile Call Handling

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mobile phone users face issues where callers incorrectly assume they are being rudely screened when their calls are quickly diverted to voicemail, leading to potential loss of business opportunities and social repercussions, due to the lack of graceful feedback mechanisms.

Innovation Solution

A mobile device system that allows users to select a control to send predefined or dynamically generated messages to callers, indicating their temporary unavailability and providing context for the call rejection, while muting the microphone and adjusting the call status accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the call is quickly diverted to voicemail without ringing through, then the user can quickly silence the ringing telephone and avoid disturbances, but the caller may wrongly presume the callee is rudely screening their call

Engineering Contradiction:

Improvetime to silence ringing telephoneVSAvoidinformation about call status to caller

Core Design Contradiction:

Loss of timeVSLoss of information

Solution Approach 1:

The system sends a feedback message to the caller indicating that the call was received and will be returned, preventing the caller from mistakenly assuming they were screened. This resolves the information loss while maintaining quick call handling.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

A message transmission mechanism acts as an intermediary between the call routing system and the caller, conveying the user's intent to return the call without requiring the user to manually communicate with the caller.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the user manually sends the call through to voicemail without ringing through, then the user can quickly silence the ringing telephone, but the caller may take umbrage at the supposed personal slight

Engineering Contradiction:

Improveease of silencing ringing telephoneVSAvoidsocial and business repercussions

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system automatically provides feedback to the caller that the call was received and will be returned, eliminating the harmful social repercussions while maintaining the ease of quickly silencing the telephone.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs the feedback communication autonomously without requiring the user to manually contact the caller, maintaining ease of operation while preventing social misunderstandings.

Inventive Principle:

Principle #25Self-service

3Loss of information

If the device provides detailed feedback messages to the caller, then the caller receives context about the user's unavailability, but the device complexity increases

Engineering Contradiction:

Improvecontext information to callerVSAvoidcomplexity of message generation system

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system uses pre-configured message templates that are prepared in advance, allowing detailed contextual feedback to be provided without requiring complex real-time message generation capabilities.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system adjusts message parameters such as timing and content selection based on call duration and user preferences, providing appropriate context without requiring overly complex processing.

Inventive Principle:

Principle #35Parameter changes
