Hinge Module Linkage Mechanism for Portable Device Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of traditional hinges in portable electronic devices often results in mechanical interference during rotation, limiting the ability to achieve a favorable screen-to-body ratio and smooth opening and closing due to a fixed rotating radius and distance between shafts.
Innovation Solution
A hinge module with a linkage mechanism comprising a first and second rotating shaft and a linking rod, allowing the second rotating shaft to move closer to or further from the first rotating shaft as the device bodies rotate, thereby avoiding mechanical interference and enabling smooth opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-type hinge with constant distance between rotating shafts is used, then the hinge structure is simple and easy to manufacture, but mechanical interference occurs during rotation limiting screen-to-body ratio
Solution Approach 1:
The hinge module transforms the fixed-distance shaft connection into a dynamic variable-distance connection through a linkage mechanism. The second rotating shaft is connected to the first rotating shaft via a linking rod that can change its distance dynamically during rotation, allowing the hinge to adapt its geometry to avoid mechanical interference and achieve higher screen-to-body ratio while maintaining operational smoothness.
2Ease of operation
If the rotating radius of the hinge is limited, then the hinge structure remains compact, but mechanical interference between device bodies occurs during rotation
Solution Approach 1:
The hinge module changes the geometric parameters of the rotation mechanism by introducing a variable-distance linkage. The distance between the first rotating shaft and the second rotating shaft changes dynamically during rotation, allowing the mechanism to navigate around mechanical interference zones while maintaining a compact overall structure, thus achieving smooth opening and closing without increasing the hinge's stationary volume.

AI summary
A hinge module (100) including a first bracket (110), a linking rod (134), and a second bracket (120). A first rotating shaft (131) is disposed on the first bracket (110). The linking rod (134) has a first end (134a) and a second end (134b) opposite to each other. The first end (134a) is pivoted to the first rotating shaft (131). A second rotating shaft (133) is disposed on the second bracket (120) and movably and pivotably connected to the first bracket (110). The second end (134b) of the linking rod (134) is pivoted to the second bracket (120). In a process where the first bracket (110) and the second bracket (120) are rotated relatively, the first rotating shaft (131) and the second rotating shaft (133) are moved close to or away from each other. A portable electronic device (10) is also disclosed.
