Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices with multiple displays face challenges in user convenience, particularly for those unfamiliar with various input methods, leading to inconvenience when executing functions.
Innovation Solution
A method for controlling multiple displays in wearable devices that activates or deactivates displays based on whether the device is worn on the user's face, allowing pre-use interaction through one display and enhanced functionality post-wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays are provided in wearable device, then functionality and information provision are improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic display control where the system automatically activates or deactivates specific displays based on detected wearing conditions. Sensors monitor whether the device is worn on the face, and this detection dynamically determines which display (first display for worn state, second display for unworn state) should be active, allowing the system to adapt its functionality to the current usage context.
Solution Approach 2:
The patent divides the display functionality into separate, dedicated displays for different usage scenarios. The first display is specifically designated for when the device is worn on the face, while the second display is designated for when the device is not worn. This segmentation allows each display to be optimized for its specific purpose and enables independent control of each display based on wearing conditions.
2Ease of operation
If display activation is based on wearing detection, then ease of operation is improved, but loss of time occurs during transition
Solution Approach 1:
The patent performs preliminary actions by pre-configuring the system with both display modes ready to activate. The sensors continuously monitor wearing conditions, and the system maintains readiness to switch between display modes instantly when the wearing state changes, eliminating the need for manual setup or configuration time during transitions.
Solution Approach 2:
The patent implements a feedback mechanism where sensors continuously detect whether the device is being worn on the face, and this detection feedback automatically triggers the appropriate display activation. The system monitors the wearing state in real-time and responds immediately by activating the first display when worn or the second display when not worn, creating an automatic control loop that eliminates manual intervention.

AI summary
An electronic device according to an embodiment may comprise: a first display disposed on the first surface of the electronic device facing a user's face based on the electronic device being worn on the user's face; a second display disposed on the second surface of the electronic device opposite to the first surface; a sensor; and at least one processor, comprising processing circuitry, operatively connected to the first display, the second display, and the sensor. At least one processor, individually and/or collectively, may be configured to cause the electronic device to: identify, through the sensor, whether the electronic device is worn on the user's face; activate the second display based on identifying that the electronic device is not worn on the user's; and display a second screen related to a first screen through the first display based on identifying that the electronic device is worn on the user's face while the first screen is displayed through the activated second display.
