Foldable Screen Notification Display Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connected wristbands and smartwatches struggle to effectively alert users of notifications due to limited screen space and complexity of sensors required for orientation and bending detection, which complicates the readability of notifications.
Innovation Solution
A foldable screen device with two rendering modes based on the connection state of its elements, optimizing notification display by using simple technical means to ensure maximum readability when worn or removed, including displaying notification content and response shortcuts on a flexible or articular screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are used to detect orientation or bending of the bracelet, then the readability of notifications can be improved, but the complexity and size of the device increases
Solution Approach 1:
The connection elements themselves serve the dual function of mechanical connection and orientation detection. When the elements are connected, the system automatically detects the bent state and adjusts notification display accordingly, without requiring separate sensors.
Solution Approach 2:
The connection elements are designed to perform multiple functions: maintaining the loop shape, enabling mechanical connection, and providing orientation information for notification display. This eliminates the need for dedicated sensors.
2Ease of operation
If the screen is made small to fit in a wristband, then the device can be worn comfortably, but the readability of notifications decreases
Solution Approach 1:
The notification display dynamically adapts based on the detected connection state. When bent (worn mode), compact notifications are shown. When flat (removed mode), expanded notifications with full content are displayed, optimizing readability for each context.
Solution Approach 2:
The system changes display parameters such as text size, notification content detail, and layout based on the connection state detection, transforming the same physical screen into two different effective display sizes.
3Adaptability or versatility
If functional modules are added to the wristband, then the device functionality increases, but the available space for components decreases
Solution Approach 1:
Multiple functions are merged into the connection elements, which simultaneously provide mechanical connection, structural support, and orientation detection capabilities, reducing the overall component volume required.

AI summary
A device (1) with an elongated foldable screen includes first and second connection elements (6a, 6b) that connect to maintain a loop-shaped substrate carrying the screen, a receiving unit (21) that receives notifications from an external device, and a control unit (22) for controlling the display of received notifications according to a first or second display mode. The control unit (22) detects the connection state of the first and second connection elements (6a, 6b) and controls the display of a received notification, according to the first or second display mode, depending on the detected connection state of the connection elements (6a, 6b).The first and second modes of rendering may include, respectively, the display of a symbolic or abbreviated representation indicating the notification received or the display of the content of a message signaled by the notification received, depending on whether the first and second connection elements are connected or disconnected.
