Flexible Screen Module Sliding Housing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face a challenge in balancing portability and user experience due to the fixed size of their display screens, with large screens compromising portability and small screens offering poor use experience.
Innovation Solution
An electronic device design featuring a housing assembly with a sliding mechanism that allows a flexible screen module to unfold and retract, utilizing a tension assembly with an elastic member and movable member to adjust the screen's size, enabling both compact and expanded display options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-size display screen is adopted, then the use experience is improved, but the portability deteriorates
Solution Approach 1:
The display screen transitions from a static fixed size to a dynamic variable size through the sliding mechanism. The first housing can slide relative to the second housing, allowing the flexible screen module to unfold to increase display area or retract to reduce device size, thus resolving the contradiction between display area and portability
Solution Approach 2:
The flexible screen module is nested within the housing assembly when retracted, with the first housing containing the unfolded screen portion. This nesting arrangement allows the large display area to be compacted into a smaller portable form factor, addressing both display area requirement and portability constraint
2Length of moving object
If a small-size display screen is adopted, then the portability is improved, but the use experience deteriorates
Solution Approach 1:
The display screen transitions from a static fixed size to a dynamic variable size through the sliding mechanism. The first housing can slide relative to the second housing, allowing the flexible screen module to unfold to increase display area or retract to reduce device size, thus resolving the contradiction between display area and portability
3Area of stationary object
If a flexible screen module with sliding mechanism is implemented, then both portability and use experience are improved, but the device complexity increases
Solution Approach 1:
The housing is segmented into a first housing and a second housing that can slide relative to each other. This segmentation allows the flexible screen module to be divided into portions that can be stored in different housing sections, enabling the unfolding/retracting function while maintaining a relatively simple overall structure
Solution Approach 2:
The elastic member acts as an intermediary component between the flexible screen module and the housing assembly. It provides automatic tensioning and positioning forces, simplifying the control mechanism needed to manage the flexible screen's unfolding and retracting movements
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 design enhances user experience by providing a larger display area while maintaining portability, as the flexible screen module can be easily expanded and retracted, accommodating various usage scenarios.
Implementation Method 1
The tension assembly includes an elastic member and a movable member... In the process of the flexible screen module retracting into the housing assembly, the movable member is driven by the elastic member to swing and to restore

AI summary
Provided is an electronic device, including a housing assembly (10), a tension assembly (60), and a flexible screen module (20). The housing assembly (10) includes a first housing (12) having a first supporting surface (12a), and a second housing (14) having a second supporting surface (14a). The tension assembly (60) is connected to the housing assembly (10). The flexible screen module (20) has a fixed end (20a) connected to the first housing (12) and supported by the first supporting surface (12a), and a free end (20b) connected to the tension assembly (60) and bypassing an end of the second housing (14) facing away from the first housing (12) and extending into the housing assembly (10). The first housing (12a) is movable relative to the second housing (14), enabling at least a part of the flexible screen module (20) to unfold on the second supporting surface (14a) or to retract into the housing assembly (10).
