Solution Overview

Problem

Current SMS deletion methods in mobile phones do not allow users to read the content of messages before deletion, leading to accidental deletions, especially for messages from unknown numbers or those requiring verification of saved phone numbers.

Innovation Solution

A terminal with a batch selection interface, a determination unit, and an execution unit that automatically determines whether selected content meets preset conditions for deletion, allowing users to view detailed information before confirming deletion, thereby reducing accidental deletions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If batch deletion mode is used to clean up SMS quickly, then productivity is improved, but reliability deteriorates because users cannot read content before deletion

Engineering Contradiction:
ImproveSMS cleanup speedVSAvoiddeletion accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism by providing a preview function that displays SMS content before deletion. When users select messages for batch deletion, they can review the content through the preview interface, receive system reminders about important messages, and confirm or cancel deletion based on the feedback received. This resolves the contradiction by enabling informed deletion decisions while maintaining batch processing efficiency.

Inventive Principle:
Principle #23Feedback

2Reliability

If batch selection mode allows reading SMS content, then reliability improves, but device complexity increases

Engineering Contradiction:
Improvedeletion accuracyVSAvoidinterface complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the content review function from the main batch deletion interface into a separate preview interface. This allows the batch deletion mode to remain simple and efficient for selecting messages, while the preview function provides comprehensive content viewing capabilities when needed. The separation of functions reduces interface complexity while maintaining deletion reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the deletion process into distinct stages: batch selection, content preview (optional), and final confirmation. Each stage has a specific function and interface optimized for that purpose. This segmentation allows the system to provide detailed content review capabilities without making the overall batch deletion interface complex, as users only engage with the preview function when needed.

Inventive Principle:
Principle #1Segmentation

3Reliability

If manual locking function is used to protect important SMS, then reliability improves, but ease of operation deteriorates

Engineering Contradiction:
Improvemessage protectionVSAvoidoperation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements automatic detection and protection mechanisms that work without requiring manual user configuration. The system automatically identifies potentially important messages (such as those containing phone numbers or sensitive information) and provides protective measures like preview reminders during batch deletion. This self-service approach maintains reliability by protecting important messages while preserving ease of operation, as users don't need to manually lock each message but rather receive intelligent assistance during the deletion process.

Inventive Principle:
Principle #25Self-service

AI summary

Provided are a terminal and a method for deletion of specified content. The terminal includes: a determination unit for determining whether a specified content meets a present condition when receiving an operation instruction to delete the specified content; and an execution unit for determining whether to execute a deletion operation on the specified content according to a determination result. By means of the technical solution of the present invention, the probability of accidental deletions can be reduced, thereby enabling a deletion operation to be safer.
