A foldable assembly comprising a base, swing arm mechanism, door panel mechanism, and elastic support member, which allows for a simple structure by forming a triangular accommodating cavity for the flexible screen in the folded state and supporting it in the unfolded state, using a swing arm and door panel rotation with an elastic support member that can be bent to avoid screen deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a variety of structures are used in the foldable assembly to achieve folding functionality, then the folding function is implemented, but the structure becomes complex and costs increase
Solution Approach 1:
The patent combines multiple functions into a unified foldable assembly structure. The swing arm mechanism and door panel mechanism are integrated to work together as a coordinated system, where the swing arm provides rotational movement and the door panel provides the folding action. This merging of mechanisms reduces the number of separate components needed while maintaining the folding functionality.
Solution Approach 2:
The foldable assembly is designed as a multi-functional mechanism that can accommodate different screen sizes and folding configurations. The swing arm mechanism with adjustable angles and the door panel mechanism work together to provide both folding and support functions, making the assembly adaptable to various electronic device configurations without requiring separate specialized components.
2Adaptability or versatility
If a variety of structures are used in the foldable assembly to achieve folding functionality, then the folding function is implemented, but costs increase
Solution Approach 1:
By integrating the swing arm mechanism and door panel mechanism into a unified foldable assembly, the patent reduces the total number of parts that need to be manufactured and assembled. This consolidation lowers manufacturing complexity and associated costs while maintaining the required folding functionality.
Solution Approach 2:
The patent employs standardized components with adjustable parameters, such as the swing arm rotation angle and door panel dimensions, that can be modified to accommodate different device requirements. This approach allows for cost-effective manufacturing through standardization while maintaining adaptability to various configurations.
3Volume of moving object
If the elastic support member is bent to form avoidance space, then the flexible screen is accommodated in folded state, but bending stress is applied to the screen
Solution Approach 1:
The elastic support member acts as an intermediary between the foldable assembly structure and the flexible screen. When the assembly folds, the elastic support member bends to create avoidance space, allowing the screen to be accommodated without direct contact with rigid structures. This intermediary function protects the screen while enabling compact folding.
Solution Approach 2:
The elastic support member provides beforehand cushioning by being positioned to bend and create avoidance space before the screen reaches areas of high stress during folding. This pre-positioned elastic element absorbs and distributes bending stress, preventing concentrated loads that could damage the screen.
4Volume of moving object
If the swing arm and door panel rotate to fold the device, then the device size is reduced for carrying, but mechanical stability may be affected
Solution Approach 1:
The foldable assembly is segmented into distinct functional components: the swing arm mechanism for rotation, the door panel mechanism for folding, and the elastic support member for support. This segmentation allows each component to be optimized for its specific function while working together to maintain overall mechanical stability during folding and unfolding operations.
Solution Approach 2:
The patent employs dynamic mechanisms where the swing arm and door panel can rotate and adjust their positions during folding and unfolding. This dynamic design allows the structure to adapt to different states (folded and unfolded) while maintaining mechanical stability in each state through proper geometric relationships and support mechanisms.

AI summary
This application provides a foldable assembly and an electronic device, and relates to the field of electronic device technologies, so as to resolve problems of a complex structure and relatively high costs of the foldable assembly. The foldable assembly includes a base, a swing arm mechanism, a door panel mechanism, and an elastic support member. The base extends in a first direction. The swing arm mechanism includes a first swing arm and a second swing arm. In a second direction, the first swing arm and the second swing arm are respectively located on two sides of the base and are hinged to the base. The door panel mechanism includes a first door panel and a second door panel. The first door panel rotates together with the first swing arm, and the second door panel rotates together with the second swing arm. Two end portions of the elastic support member in the second direction are respectively connected to the first door panel and the second door panel. When the first swing arm and the second swing arm are at an unfolded position, the elastic support member is in a flat plate state and is configured to support a flexible screen; and when the first swing arm and the second swing arm are at a folded position, the elastic support member is bent to form avoidance space for accommodating a part of the flexible screen.
