Rollable Display Rack-and-Slide Structure for Expandable Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in providing a flexible display that can expand or contract to accommodate varying user needs while maintaining functionality and ease of use.
Innovation Solution
An electronic device with a flexible display that includes a first and second housing, where the second housing slides relative to the first, featuring a flexible display with extendable areas, a battery, a rack gear, and a motor driver to facilitate sliding movement, and a rack guide to support the gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is increased to accommodate multimedia services, then the functionality and user experience are improved, but the device size and portability are worsened
Solution Approach 1:
The patent implements a dynamic display system where the second housing can slide relative to the first housing, allowing the display area to change from a compact state to an expanded state. The display transitions from a first display area to a larger second display area through mechanical movement, enabling the device to adapt its size based on usage needs rather than being fixed at a large size for all scenarios.
Solution Approach 2:
The patent employs a nested structure where the second housing containing the flexible display is positioned within or adjacent to the first housing. When not in use, the extended display area can be retracted or folded into a compact configuration, allowing the larger display to be stored within the boundaries of the smaller housing, similar to nested dolls.
2Adaptability or versatility
If the display area is made flexible and extendable, then the adaptability is improved, but the device complexity is worsened
Solution Approach 1:
The patent divides the display system into distinct segments: a first housing with a first display area and a second housing with a second display area. These segments can move independently relative to each other, allowing the display to be segmented into different operational states (compact vs. extended) without requiring a completely complex reconfiguration of the entire display system.
Solution Approach 2:
The patent introduces a motor driver as an intermediary component that automates the sliding mechanism between the first and second housings. This intermediary device simplifies the user interaction by providing motorized control rather than manual operation, reducing the complexity of user control while managing the mechanical complexity internally through automated actuation.

AI summary
An electronic device is provided. The electronic device includes a first housing, a second housing configured to slide with respect to the first housing, a flexible display including a first display area and a second display area extending from the first display area, the second display area configured to move based on the sliding movement of the second housing, a battery disposed in the first housing, a rack gear coupled to the first housing, a motor drive disposed in the second housing and configured to provide driving force for the sliding movement of the second housing by being connected to the rack gear, and a rack guide disposed in the second housing and surrounding at least a portion of the rack gear.
