Mobile Terminal Lock Screen Memo Writing and Event Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals with restricted functions, such as those with a lock screen enabled for privacy protection, do not allow convenient memo writing or utilization of written memos in a state where certain functions are limited.
Innovation Solution
A mobile terminal and controlling method that enables memo writing on a lock screen with user authentication, allowing automatic handling of events and utilization of the memo even after the lock screen is cancelled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock screen is enabled to restrict functions for privacy protection, then security is improved, but the ability to write memos and utilize them is worsened
Solution Approach 1:
The patent segments the memo writing functionality from the main terminal functions. By creating a dedicated memo writing mode that operates independently within the locked state, the system allows memo writing without requiring lock screen cancellation, thus maintaining both security and ease of operation for this specific function
Solution Approach 2:
The patent introduces an intermediary mechanism where the memo writing mode acts as a mediator between the locked state and the memo utilization state. The system captures memos during locked state and automatically transfers them to the memo list upon lock screen cancellation, eliminating the need for manual transfer operations
2Reliability
If functions are restricted during lock screen status, then security is improved, but the ability to automatically handle events is worsened
Solution Approach 1:
The patent implements preliminary action by capturing memos during the locked state before the lock screen is cancelled. The system prepares and stores the memos in advance, so that when the lock screen is cancelled, the memos are already available in the memo list and can be automatically utilized for event handling without requiring additional user input
Solution Approach 2:
The system performs self-service by automatically transferring captured memos to the memo list and enabling automatic event handling without requiring manual intervention. The memo writing mode automatically saves memos and the system automatically utilizes them for events such as incoming calls or messages, reducing the need for user involvement in the automation process
3Ease of operation
If lock screen is cancelled to utilize memos, then ease of operation is improved, but security protection is worsened
Solution Approach 1:
The patent segments the memo writing function from the main terminal functions, allowing it to operate independently within the locked state. This segmentation enables memo capture without requiring lock screen cancellation, thus maintaining security while providing ease of operation for memo writing and subsequent utilization
Solution Approach 2:
The patent introduces an intermediary mechanism where the memo writing mode acts as a mediator between the locked state and the memo utilization state. The system captures memos during locked state and automatically transfers them to the memo list upon lock screen cancellation, eliminating the need for manual transfer operations and reducing security compromise

AI summary
A mobile terminal and controlling method therein are disclosed, by which a memo can be written and utilized conveniently in a state that an access to the mobile terminal is restricted in part. The present invention includes entering a lock screen for restricting at least one partial function of the mobile terminal, writing a memo on the lock screen in response to an input of a 1st command, and if user authentication is performed in response to an input of a 2nd command, coping with an event occurring until cancellation of the display of the lock screen using the memo.
