Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices face challenges in optimizing user interface operations and screen display management across multiple displays, particularly in transitioning between folded and unfolded states, leading to inefficiencies and user inconvenience.
Innovation Solution
A foldable electronic device with a main display and a sub-display, equipped with sensors to detect rotation, wakes up the sub-display based on detected rotation, allowing seamless display of application screens and input management across both displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the sub-display remains in sleep mode to save energy, then energy consumption is reduced, but the responsiveness and user convenience when rotating the device deteriorates
Solution Approach 1:
The patent applies dynamics by making the sub-display's operational state changeable based on device rotation. The sub-display transitions between sleep mode and active state dynamically in response to rotation events, allowing the system to adapt its energy consumption and responsiveness characteristics according to actual usage needs.
Solution Approach 2:
The system uses sensor feedback to detect device rotation and automatically triggers the sub-display wake-up. This feedback mechanism ensures that the sub-display activates in response to rotation events without requiring manual user intervention, balancing energy efficiency with responsive operation.
2Ease of operation
If the sub-display is always active to provide immediate display functionality, then user convenience and display availability are improved, but energy consumption increases
Solution Approach 1:
The sub-display operates in periodic cycles, alternating between active and sleep states based on rotation events. Instead of remaining continuously active, the display activates periodically when rotation is detected and returns to sleep mode afterward, reducing overall energy consumption while maintaining display availability when needed.
3Adaptability or versatility
If multiple displays are used to provide expanded functionality, then device versatility and user experience are improved, but device complexity increases
Solution Approach 1:
The sub-display is designed to serve multiple functions: it can display notifications, provide additional information, serve as a secondary interface, and wake up in response to rotation. This multi-functionality approach allows a single additional display component to provide expanded versatility without proportionally increasing system complexity.
