Solution Overview

Problem

Current voicemail systems do not allow callers to access voicemail messages left for others after disconnecting from the callee's voicemail system, as these messages are only stored in the callee's inbox and not in the caller's system.

Innovation Solution

Implementing a method to automatically fork a copy of the voicemail message to the caller's voicemail system in real-time while the message is being recorded, allowing the caller to store and access the message independently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the voicemail message is stored only in the callee's inbox, then the callee can access and manage the message, but the caller cannot access the message after disconnecting from the callee's voicemail system

Engineering Contradiction:
Improvecaller's access to voicemail messageVSAvoidvoicemail system architecture
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent divides the voicemail storage function into two separate locations: the callee's inbox (for primary storage and callee access) and the caller's voicemail box (for caller access and retention). This segmentation allows both parties to independently access and manage their respective copies of the voicemail message without interfering with each other's control over the message.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a copy of the voicemail message and stores it in the caller's voicemail box while the caller is connected to the callee's voicemail system. This copying mechanism ensures that the caller retains a local copy of the message for future access, playback, or forwarding without requiring reconnection to the callee's system.

Inventive Principle:
Principle #26Copying

2Ease of operation

If the caller records the voicemail offline and sends it later, then the caller can retain the message, but most real-time communications cannot access the message after leaving it

Engineering Contradiction:
Improvecaller's ability to retain and forward messagesVSAvoidcompatibility with real-time communication protocols
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent performs the copying action preliminarily - while the caller is still connected to the callee's voicemail system in real-time. The system automatically forks and stores a copy of the voicemail message in the caller's box during the active connection, before the caller disconnects. This preliminary action enables subsequent easy access and forwarding operations without requiring the caller to re-record or re-connect.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If a copy of the voicemail message is forked to the caller's voicemail system in real-time, then the caller can access and forward the message independently, but the system complexity increases

Engineering Contradiction:
Improvemessage retention and accessibilityVSAvoidreal-time forking mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary mechanism - the caller's voicemail system - that acts as a local storage and management point for the voicemail message. This intermediary receives the forked copy during the real-time connection and independently manages the message locally, reducing the need for continuous connection to the callee's system and improving reliability of message access.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Techniques for storing voicemails in real-time in a caller's voicemail system when a voicemail is left in a callee's voicemail system are provided. A connection to the callee's voicemail system is detected during a call from the caller to the callee. When a voicemail is being left on the caller's voicemail system, a copy of the voicemail message is automatically forked to the caller's voicemail system. Thus, when a voicemail message is recorded on the callee's voicemail system, a copy of the voicemail message is also stored on the caller's voicemail system.
