Flexible Display Gear Mechanism for Wearable Screen Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices worn on the body face limitations in increasing screen size, making it difficult to provide large-screen displays, which compromises user convenience and information delivery.
Innovation Solution
An electronic device with a flexible display that can rotate and extend, utilizing a gear structure and mounting member to expose a larger screen area, allowing for adjustable display size based on user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electronic device is made in reduced size, then it can be worn on the user's body part, but the screen display area becomes small which deteriorates user convenience
Solution Approach 1:
The flexible display is designed to be dynamically extendable from the compact wearable form factor. The display can transition between a retracted state for compact storage and an extended state for providing a large screen area, allowing the device to adapt its display size based on operational needs rather than being fixed during manufacturing.
Solution Approach 2:
The display structure is segmented into a main body portion integrated with the wearable device and an extendable flexible display portion. This segmentation allows the display to be divided into a compact core for wearable form and an extendable component that can be deployed when needed, resolving the contradiction between small device size and large display area.
2Area of stationary object
If the screen display area is increased, then various pieces of visual information can be provided, but the device cannot be made compact for wearable use
Solution Approach 1:
The flexible display is nested within the wearable device housing, allowing the display to be stored in a compact configuration when not in use. The display can be unrolled or extended from within the device body, similar to a nested doll, providing a large screen area only when needed while maintaining a compact form factor during storage.
Solution Approach 2:
The display transitions dynamically between a compact nested state for wearable comfort and a large extended state for information display. This dynamic transformation allows the device to provide a large screen area on demand without permanently increasing the device volume, resolving the contradiction between display size and compactness.
3Ease of operation
If a flexible display is added to increase screen area, then user convenience is improved, but device complexity increases
Solution Approach 1:
A flexible display module with a thin, flexible structure is integrated into the device, allowing the display to bend and extend without requiring complex mechanical support structures. The flexibility of the display itself simplifies the overall mechanism compared to rigid display alternatives, reducing the complexity penalty while maintaining the ability to provide large screen area.
