Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with multiple bodies, such as notebook computers, cannot be flexibly bent, resulting in a non-integral appearance when folded, as they lack the ability to maintain a constant inner arc length during bending.
Innovation Solution
An electronic device comprising a flexible connection device with N shafts and N−1 transmission structures, where each transmission structure connects two adjacent shafts, allowing the device to bend while maintaining a constant inner arc length by rotating the shafts and transmission structures sequentially when an action force is applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rigid connection structures are used to connect multiple bodies, then structural strength is maintained, but the device cannot be flexibly bent and loses integral appearance
Solution Approach 1:
The connection device is divided into multiple shafts (N shafts) and transmission structures (N-1 transmission structures), where each component can rotate independently. This segmentation allows the overall structure to achieve flexible bending while maintaining strength through the coordinated rotation of individual segments.
Solution Approach 2:
The connection device transitions from a rigid static structure to a dynamic structure where shafts can rotate relative to each other through transmission structures. This dynamic capability enables the device to adapt its shape for flexible bending while maintaining structural integrity through controlled movement.
2Adaptability or versatility
If the connection device is made flexible to enable bending, then adaptability is improved, but the inner arc length changes during bending
Solution Approach 1:
The transmission structures are designed with specific geometric parameters that change during rotation to compensate for the bending curvature. As shafts rotate, the transmission structures adjust their effective length and angle, maintaining a constant inner arc length throughout the bending process.
Solution Approach 2:
The connection device incorporates curved transmission structures with specific radius of curvature that match the desired bending path. This curvature design ensures that when shafts rotate, the inner arc length remains constant while achieving smooth flexible bending.
3Adaptability or versatility
If multiple shafts and transmission structures are used to achieve flexible bending, then bending capability is improved, but device complexity increases
Solution Approach 1:
Each transmission structure is designed to perform multiple functions: connecting adjacent shafts, transmitting rotational motion, maintaining constant inner arc length, and providing structural support. This multi-functionality reduces the need for additional specialized components, simplifying the overall device despite the multiple shafts required.

AI summary
An embodiment of the present disclosure provides an electronic device and a flexible connection device. The electronic device comprises a first body; a second body; and a flexible connection device, configured to connect the first body and the second body. The flexible connection device comprises N shafts; and N−1 transmission structures, wherein each of the transmission structures connects two adjacent shafts, to connect the N shafts together in order, wherein N is an integer which is larger than 3 or equals to 3. When an action force is applied onto the first body and/or the second body so that relative positions of the first body and the second body are changed, the N shafts and the N−1 transmission structures are driven sequentially so that the flexible connection device is flexibly bent while keeping the length of the inner arc of the flexible connection device constant.
