Solution Overview

Problem

Existing email systems are inefficient in communicating task requests to a group, as they often require sequential responses and can lead to duplicated work, as individuals need to notify the entire recipient list about task acceptance and completion, which is time-consuming and inefficient.

Innovation Solution

Implementing a one-responder email feature that allows only one recipient to accept and complete a task within the email message, with status updates communicated through email exchanges, preventing multiple users from working on the same task and eliminating the need for external tracking processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If email messaging is used to notify a group of persons when one person signs up for or undertakes the task, then communication of task status is achieved, but numerous email messages are exchanged and time is consumed

Engineering Contradiction:
Improvetask status communicationVSAvoidtime for email exchanges
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent combines multiple email notifications (task acceptance notification, task completion notification, and status updates) into a single automated email message. When a user accepts or completes a task, the system sends one consolidated email to all relevant recipients, eliminating the need for multiple separate email exchanges and reducing time loss.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of information

If the individual who has decided to complete the task replies to the entire email recipient list, then notification of task acceptance is achieved, but numerous email messages are exchanged to people who were unaware of or unable to execute the task

Engineering Contradiction:
Improvetask acceptance notificationVSAvoidemail message exchange complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts the notification function from manual user actions and implements it as an automated system feature. When a user accepts a task, the system automatically extracts and sends notifications only to relevant recipients (those who need to know about the task assignment), eliminating the need for the user to manually reply to the entire recipient list and reducing unnecessary message exchanges.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary email server system that manages task acceptance notifications. Instead of users directly replying to entire recipient lists, the intermediary system receives the task acceptance signal and automatically distributes notifications to appropriate recipients, simplifying the communication process and reducing message complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a priority email address list method is used to assign tasks, then duplicated work is prevented, but a large amount of time is taken to operate and the system is relatively inefficient

Engineering Contradiction:
Improveprevention of duplicated workVSAvoidtask assignment efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements preliminary action by pre-configuring the email system with one-responder capability and automated notification rules before task assignment. When a task is sent with the one-responder flag, the system is already prepared to automatically manage notifications and prevent duplicate acceptances, eliminating the need for time-consuming sequential processing and improving productivity while maintaining reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism where the email system automatically monitors task acceptance status and provides real-time feedback to senders and recipients. When a task is accepted, the system immediately feedbacks this status to all recipients, preventing duplicate work and enabling efficient parallel processing of multiple tasks, thereby improving overall system productivity.

Inventive Principle:
Principle #23Feedback

4Loss of information

If sequential task assignment is used, then task acceptance is tracked, but communication of task status occurs in sequential fashion rather than parallel

Engineering Contradiction:
Improvetask status trackingVSAvoidsequential processing time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent segments the task management process into independent, parallelizable components: task distribution, acceptance tracking, and status notification. Each recipient receives and processes the task independently in parallel, and the system segments notifications to be sent simultaneously to all relevant parties, eliminating sequential delays while maintaining accurate status tracking through the email exchange mechanism.

Inventive Principle:
Principle #1Segmentation

AI summary

The present invention discloses a method for allowing an email request to be sent to a group of recipients which requires one person to accept the request or task. Obtaining notification of the acceptance and completion status of the task is accomplished solely through exchanged emails, without the use of standalone tracking or modification to the underlying email system functionality. One responder emails are sent to a group of recipients, and when an accepting recipient accepts the request, the sender and non-accepting recipients are notified via email that the request has been accepted. Similarly, emails can be sent to the sender and non-accepting recipients that the request has been completed.
