Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional instant messaging applications lack the ability to efficiently edit or modify previously sent messages, leading to issues such as bandwidth waste and user dissatisfaction, particularly on devices with limited input and output capabilities.

Innovation Solution

A method and apparatus for instant messaging applications that allow users to dynamically modify previously transmitted chat messages by adding special effects, inserting or deleting messages, and generating chat clips, which can be shared or posted externally.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users send multiple messages or use images instead of text to convey emotional concepts, then communication effectiveness is improved, but bandwidth consumption increases

Engineering Contradiction:

Improvecommunication effectivenessVSAvoidbandwidth consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies dynamics by allowing users to modify previously sent messages dynamically. Users can add special effects, change formatting, or append to existing messages after they are sent, enabling emotional concepts to be conveyed through text modifications rather than sending multiple separate messages or images, thus reducing bandwidth consumption while maintaining communication effectiveness

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes parameters of existing messages by allowing users to modify text content, add special effects, and alter message formatting. This enables the same message to serve multiple communication purposes through parameter changes rather than requiring additional messages, reducing overall bandwidth consumption

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If traditional instant messaging applications do not allow message modification, then system simplicity is maintained, but user satisfaction decreases due to inability to correct or enhance previous messages

Engineering Contradiction:

Improveuser satisfactionVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by allowing users to modify messages before they are fully sent or immediately after sending. The system prepares modification capabilities in advance, enabling users to correct errors or enhance messages without requiring complex post-processing or alternative communication methods, thus improving user satisfaction while keeping the interface simple

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a modified version of the original message rather than replacing it entirely. Users can append modifications to existing messages or create variant versions, allowing message evolution without requiring complete message retransmission, thus balancing user satisfaction with system simplicity

Inventive Principle:

Principle #26Copying

3Loss of information

If users send multiple separate messages to convey different aspects of a conversation, then communication clarity is improved, but time consumption increases

Engineering Contradiction:

Improvecommunication clarityVSAvoidtime consumption

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent applies merging by allowing users to combine multiple communication aspects into a single modified message. Users can append additional information, add special effects, or enhance existing messages to convey multiple meanings simultaneously, reducing the number of separate messages needed and thus saving time while maintaining communication clarity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent ensures continuity of useful action by allowing messages to be continuously modified and enhanced. Instead of sending discrete separate messages, users can continuously add to and refine a single message thread, maintaining clarity while reducing the total time spent on communication through cumulative modifications

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A communication system using user interfaces for executing the instant messenger is provided. The system displays, in a user interface of an instant messenger application, a chatroom comprising a plurality of chat messages, receive, via the user interface, a first user input indicating a user selection of a chat section comprising one or more chat messages of the plurality of chat messages, receive, via the user interface, a second user input comprising an indication of one or more modifications to the chat section, wherein the one or more modifications comprise a modification to an output method of the chat section, generate a chat clip by generating, based on the modification to the output method, a modified version of the chat section, display, in the user interface, the chat clip, and cause a second computing device to display, in a second user interface of an instant messenger application, the chat clip.
