Solution Overview

Problem

Existing terminal devices have a high probability of mis-sending messages to the wrong recipients, and once sent, they cannot be retrieved within a specified period, leading to potential miscommunication.

Innovation Solution

The terminal device employs a message sending method that filters contacts based on preset conditions, such as message time interval, keyword recognition, and intimacy index, to reduce mis-sending by sending appropriate content to the correct recipients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the terminal device sends messages automatically after user selection, then sending efficiency is improved, but the probability of mis-sending to wrong recipients increases

Engineering Contradiction:
Improvemessage sending efficiencyVSAvoidmessage delivery accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The terminal device performs preliminary actions by detecting keywords in the message content and proactively querying the user before sending. This preliminary verification step allows the system to maintain automated sending efficiency while adding a safety check to prevent mis-sending to wrong recipients.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by monitoring message content for keywords and providing real-time alerts to the user. When sensitive keywords are detected, the system feeds back to the user for confirmation, creating a closed-loop verification process that reduces errors while maintaining overall sending efficiency.

Inventive Principle:
Principle #23Feedback

2Reliability

If the terminal device adds keyword detection and user confirmation steps, then message delivery accuracy is improved, but sending time increases

Engineering Contradiction:
Improvemessage delivery accuracyVSAvoidmessage sending time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system applies partial verification by only triggering user confirmation when specific keywords are detected in the message content. For messages without sensitive keywords, the sending proceeds automatically without additional time cost. This selective approach improves accuracy for critical messages while maintaining efficiency for routine communications.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system changes the parameter of verification intensity based on message content characteristics. By analyzing keywords and adjusting the verification level dynamically, the system reduces unnecessary confirmation steps for safe messages while applying stricter checks for sensitive content, thereby optimizing the balance between accuracy and sending time.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the terminal device implements automated keyword detection, then mis-sending probability is reduced, but system complexity increases

Engineering Contradiction:
Improvemessage sending reliabilityVSAvoidmessage processing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts only the critical function of keyword detection and user notification from the overall message sending process. By isolating this specific verification function and implementing it as a separate module that triggers only when needed, the system reduces mis-sending probability without requiring complete restructuring of the message processing architecture.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Embodiments of this disclosure provide a message sending method and a terminal device, and relate the field of terminal technologies, where the method includes: obtaining message content input by a user and contacts selected by the user; and sending the message content to a contact that does not meet a preset condition among the contacts selected by the user, and/or sending preset content to a contact that meets the preset condition among the contacts selected by the user.
