Connection Structure With Opposing Rotation Assemblies For Foldable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face challenges in minimizing the width of their connection structures to accommodate batteries while reducing creases on flexible screens during folding, as existing solutions often occupy more space and widen the device.
Innovation Solution
A connection structure featuring a first and second movement assembly that rotate in different directions, synchronously increasing the distance between their connection and free ends to form an accommodation space, allowing for a smaller width in the extended state and reduced creases in the folded state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connection structure width is reduced to make space for batteries, then the battery accommodation space is improved, but the connection structure may not provide sufficient support for flexible screen folding
Solution Approach 1:
The connection structure employs dynamic movement assemblies that can rotate and adjust their configuration. The first and second movement assemblies rotate in different directions to dynamically form an accommodation space during synchronous movement, providing structural support when needed while maintaining a compact width when folded.
Solution Approach 2:
The invention transitions from a static width reduction approach to a three-dimensional dynamic configuration. By utilizing rotational movement in multiple directions (first and second rotation directions), the connection structure creates accommodation space in the vertical dimension rather than compromising horizontal width, thus supporting flexible screens while maintaining compact form.
2Reliability
If a traditional connection structure is used to support flexible screen folding, then the folding support is improved, but the connection structure occupies larger accommodation space and wider width
Solution Approach 1:
The connection structure is divided into multiple independent movement assemblies (first and second movement assemblies) that can operate independently in different rotation directions. This segmentation allows each assembly to contribute to folding support while maintaining a narrower overall width compared to a single monolithic connection structure.
Solution Approach 2:
The movement assemblies are designed to nest within each other during rotation, with the first and second movement assemblies occupying overlapping spatial regions at different angles. This nesting arrangement reduces the overall width and accommodation space required while maintaining the structural support capability during flexible screen folding.
3Length of moving object
If the connection structure width is reduced, then the device width is improved, but the accommodation space for flexible screen in folded state decreases
Solution Approach 1:
The invention changes the spatial parameters of the connection structure dynamically through rotation. During synchronous movement of the first and second movement assemblies, the distance between connection ends and free ends increases, transforming the accommodation space parameter from a fixed small value to a variable that expands when needed for flexible screen placement.

AI summary
A connection structure includes a body, a first movement assembly movable relative to the body in a first rotation direction, and a second movement assembly movable relative to the body in a second rotation direction, the second rotational direction being different from the first rotational direction. During a first synchronous movement of the first movement assembly and the second movement assembly, a distance between a connection end of the first movement assembly and a free end of the first movement assembly increases, and a distance between a connection end of the second movement assembly and a free end of the second movement assembly increases.
