Flexible Dual-Display Wearable for Screen Size and Endurance Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent wearable devices face challenges with small screen sizes, leading to unclear reading and inconvenient operation, and limited endurance due to volume constraints.
Innovation Solution
The implementation of a dual-display system, featuring a flexible AMOLED first display screen and an electronic ink second display screen, which are foldably connected, allowing for increased screen size and power-efficient operation by selectively activating screens based on content complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the screen size is increased to improve reading clarity and operation convenience, then the display quality and user experience are improved, but the device volume increases and endurance decreases
Solution Approach 1:
The display system is segmented into two independent screens: a first display screen (flexible AMOLED) and a second display screen (electronic ink screen). Each screen can be independently controlled and activated based on usage scenarios. This segmentation allows the device to achieve large display area when needed while consuming less power during normal operation by using only the smaller electronic ink screen.
Solution Approach 2:
The first display screen is designed as a flexible display that can be dynamically adjusted in size and shape. It includes a bendable area that allows the screen to transition between different configurations - from a compact folded state to an expanded unfolded state. This dynamic flexibility enables the screen to adapt its size to match different usage requirements, providing large display area only when necessary.
2Area of moving object
If the screen size is increased to display more content, then the information display capability is improved, but the device volume increases
Solution Approach 1:
The display system is divided into two separate screens with different functions and sizes. The electronic ink screen handles basic information display, while the flexible AMOLED screen provides expanded display capability when needed. This segmentation allows the device to maintain a compact form factor while offering large screen functionality on demand.
Solution Approach 2:
The flexible first display screen can be folded or unfolded to change its effective display area. When folded, it maintains a compact profile that fits within the small device volume. When unfolded, it provides a larger display area for viewing more content. This dynamic configuration allows the device to offer large screen capability without permanently increasing its volume.
