Rollable Display Gear Assembly for Compact Housing Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face a trade-off between compactness and the need for larger displays to accommodate multimedia services, leading to a challenge in designing devices that are both portable and provide satisfactory display experiences.
Innovation Solution
The electronic device incorporates a housing with a first and second housing that can move relative to each other, a display that can be rolled or unrolled, and a motor structure with first and second gear assemblies to transfer driving force to both the housing and the display support member, allowing for efficient sliding and display expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a larger display is used to accommodate multimedia services, then the display area is improved, but the device compactness deteriorates
Solution Approach 1:
The display is divided into a first display portion and a second display portion that can be independently positioned. The first housing and second housing are segmented to allow relative sliding movement, enabling the display areas to be separated or combined as needed. This segmentation allows the device to provide a large total display area while maintaining a compact form factor when the portions are separated.
Solution Approach 2:
The first housing is received within the second housing, creating a nested structure. The display portions are arranged such that they can be positioned relative to each other within the housing structure. This nesting arrangement allows the large display area to be contained within a compact device volume when not in use.
2Adaptability or versatility
If the housing is made movable to enable display expansion, then the display versatility is improved, but the device complexity increases
Solution Approach 1:
The housing structure is made dynamic with the first housing capable of sliding relative to the second housing along a guide rail. This dynamic structure allows the device to transition between different display configurations (expanded and compact) while maintaining structural integrity. The guide rail and sliding mechanism provide controlled movement without requiring complex actuators or multiple moving joints.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables the electronic device to maintain compactness while providing a larger display area as needed, reducing the risk of display peel-off and enhancing user experience with multimedia services.
Implementation Method 1
a motor structure including a motor core configured to generate a driving force for the slide movement of the housing
Implementation Method 2
a first gear assembly connected (directly or indirectly) to the first housing and a first end of the motor structure and configured to transfer at least a portion of the driving force generated by the motor core to the first housing

AI summary
An electronic device may include a housing including a first housing and a second housing configured to receive at least a portion of the first housing and move relative to the first housing, a display configured to be rolled or unrolled based on a slide of the housing, a display supporting member supporting at least a portion of the display, a motor structure including a motor core configured to generate a driving force for the slide of the housing and disposed in the housing, a first gear assembly connected to the first housing and a first end of the motor structure and configured to transfer at least a portion of the driving force generated by the motor core to the first housing, and a second gear assembly connected to the display supporting member and a second end of the motor structure, which is opposite to the first end, and configured to transfer at least a portion of the driving force to the display supporting member.
