Linkage Mechanism for Coplanar Display Alignment in Foldable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with folding or sliding designs face issues such as wide intervals between displays in unfolded states, leading to discontinuous visual experiences and complex, difficult-to-assemble mechanisms.
Innovation Solution
A linkage mechanism is introduced, comprising a first body, a second body, and a linkage with pivot shafts, allowing the two bodies to be stacked in a retracted state and expanded to a coplanar position, with specific pivot shaft coordinates and linkage design ensuring seamless display and touch functionality while minimizing part complexity and assembly challenges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a folding-type portable electronic device is designed to be compact and portable, then the device can be easily carried, but the interval between two displaying regions becomes too wide causing discontinuous visual sensation
Solution Approach 1:
The patent employs a dynamic linkage mechanism with pivot shafts that allows the second body to rotate and adjust its position relative to the first body. This dynamic adjustment enables the displaying regions to move closer together, reducing the interval between them and creating a more continuous visual experience while maintaining compact form factor
2Ease of operation
If a sliding-type portable electronic device is designed to expand space, then the displaying regions can be positioned closer, but the mechanism becomes more complex with lots of parts and uneasy assembling
Solution Approach 1:
The patent divides the device into two main bodies (first body and second body) that can be independently positioned and connected through a linkage mechanism. This segmentation allows each body to be optimized separately while maintaining overall simplicity in the connection mechanism
Solution Approach 2:
The linkage mechanism acts as an intermediary between the first body and second body, providing a simple yet effective means of connection and position adjustment. The pivot shafts and linkage arms serve as intermediate elements that enable smooth transition between compact and expanded states without requiring complex mechanisms

AI summary
A portable electronic device includes a first body, a second body and a linkage. The first body has a first upper surface, and the second body has a second upper surface. An end of the linkage is coupled to the first body through a first pivot shaft and another end of the linkage is coupled to the second body through a second pivot shaft, in which the second body is suitable to be stacked on the first upper surface of the first body to make the portable electronic device in a retracted state. The linkage is suitable to rotate relatively to the first body so that the first body and the second body of the portable electronic device are side by side in an expanded state.
