Solution Overview

Problem

Users often overlook or misread the reception time of chat messages, leading to misunderstandings and invalid responses due to the static nature of time information in social applications, affecting user experience and accuracy in message viewing.

Innovation Solution

An information display method that determines a target time based on keywords in messages and displays prompt information when the time difference exceeds a threshold, reminding users of the valid period of the message.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electronic device displays only the reception time of chat messages, then the message interface remains simple and clear, but users may overlook or misread the time information leading to misunderstandings and invalid responses

Engineering Contradiction:

Improveaccuracy in message viewingVSAvoidcomplexity of time information display

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary analysis of message content to identify target keywords and calculate target times before displaying messages. By pre-processing the message content to extract time-related information and comparing it with the reception time, the system prepares the validity assessment in advance, so that when the user views the message, the validity indication is already ready to display, avoiding the need for complex real-time processing at the display moment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary validity indication mechanism that mediates between the simple reception time display and the need for accurate message validity assessment. This intermediary layer analyzes message content, compares target times with reception times, and provides a simplified validity indication (such as highlighting or icons) that bridges the gap between minimal display complexity and reliable message viewing.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the electronic device displays prompt information about message validity, then user accuracy in message viewing improves, but the message interface becomes more complex and cluttered

Engineering Contradiction:

Improveaccuracy in message viewingVSAvoiduser experience in message interface

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system applies local quality by providing validity indications only for specific messages that contain target keywords and have significant time differences between target time and reception time. Instead of uniformly adding complexity to all messages, the system selectively enhances only those messages that require validity attention, maintaining the simplicity and ease of operation for the majority of messages while improving reliability where needed.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system uses partial action by displaying validity indication information only when necessary (when time difference exceeds threshold), rather than always displaying comprehensive validity information. This partial display approach provides just enough information to improve user accuracy without excessively cluttering the interface, balancing reliability improvement with ease of operation.

Inventive Principle:

Principle #16Partial or excessive action

3Measurement precision

If the electronic device analyzes message content to determine target time, then message validity assessment becomes more accurate, but the processing time and computational resources increase

Engineering Contradiction:

Improveprecision of validity assessmentVSAvoidtime for message processing

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary action by extracting and storing target keywords and calculating target times when messages are received or stored, rather than analyzing the full message content every time it needs to be displayed. This pre-extraction of time-related information reduces the computational burden during display operations, maintaining high measurement precision while minimizing processing time loss.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies the extraction principle by separating the time-related information extraction from the full message content analysis. It extracts only the necessary time elements (target keywords and target times) from messages for validity assessment, rather than processing the entire message content. This extraction approach maintains precise validity assessment while significantly reducing the time and computational resources required.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

An information display method includes in a case that a first message displayed in a message interface includes a target keyword, determining a target time based on the target keyword and a first time; and in a case that a time difference between the target time and a second time is greater than or equal to a preset threshold, displaying target information. The first time is a reception time of the first message, the target information is prompt information generated based on the target time, and the second time is a current system time.
