Electronic Pen Detachment Triggers Dormant Display Memo Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing memo function in electronic devices requires users to go through cumbersome processes such as turning on the device, unlocking it, and executing the memo application to record simple notes, which is inconvenient and inefficient.
Innovation Solution
An electronic device equipped with a pen sensing module and a processor that activates the pen input module when the electronic pen is detached, allowing users to input memos directly on a dormant display, reducing the number of steps required and enabling memo recording without powering up the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user follows the conventional process to record a memo (turn on display, unlock device, execute memo application), then the memo can be recorded, but the number of operations is large and power consumption is high
Solution Approach 1:
The system performs preliminary setup by storing memo templates and configurations in advance. When a memo is needed, the pre-configured template is directly applied without requiring the user to manually create or navigate through application menus, thus reducing the number of operations and power consumption
Solution Approach 2:
The essential memo recording function is extracted from the full memo application environment. The system allows memo input through a simplified interface that can operate with minimal system activation, separating the core writing function from the complete application suite that would normally need to be executed
2Use of energy by moving object
If the display is kept in OFF-state to save power, then power consumption is reduced, but the user cannot input or verify memo content
Solution Approach 1:
The display operates in a periodic manner - remaining in OFF-state to save power, then activating briefly to allow memo input through alternative interfaces (such as touch input on the screen without full display activation), and returning to OFF-state. This periodic activation minimizes energy consumption while maintaining operational capability
Solution Approach 2:
An intermediary input mechanism is introduced that allows memo content to be captured without requiring full display activation. The system accepts input through methods that do not necessitate the display being fully ON, such as touch-sensitive input or other low-power input modalities
3Adaptability or versatility
If the memo application is executed to record a memo, then the memo function is provided, but the device complexity and unlocking process are increased
Solution Approach 1:
The memo recording capability is extracted from the locked application environment and made accessible through a separate input pathway. Users can input memo content without completing the full unlocking sequence, as the input function operates independently of the application execution framework
Solution Approach 2:
The system uses a simplified copy of the memo input interface that functions without requiring the full application to be executed. This reduced interface captures essential memo data while bypassing the need to load and run the complete memo application, thereby reducing device complexity requirements

AI summary
An electronic device is provided. The electronic device includes a display, an electronic pen, a slot in which the electronic pen can be inserted in or detached from, a pen sensing module configured to sense an insertion/detachment of the electronic pen, a pen input module configured to receive an input using the electronic pen, and a processor configured to activate the pen input module while the display maintains an OFF-state when the detachment of the electronic pen is sensed within the OFF-state of the display.
