Dual-Axis Hinge Module for Clamshell Device Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamshell-type electronic devices have structural limitations due to the need for a torsion structure, which increases the thickness of the keyboard module and restricts the design of the second electronic module, affecting heat dissipation efficiency.
Innovation Solution
A dual-axis hinge module is introduced, where the torsion structure is arranged in the first electronic module only, allowing the second electronic module to have a variable distance for improved heat dissipation by relocating the mounting portion, thus eliminating the need for a torsion structure on the fixing shaft and enabling greater flexibility in design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a torsion structure is installed in the keyboard module to provide torsion for the rotation of the display module, then the rotation function is achieved, but the maximum thickness of the keyboard module must be larger than that of the torsion structure
Solution Approach 1:
The torsion structure is extracted from the keyboard module and relocated to the display module. The fixing shaft is fixed to the keyboard module without torsion structure, while the moving shaft with torsion structure is fixed to the display module, allowing the keyboard module thickness to be reduced to below 5mm while maintaining the rotation function through the dual-axis hinge mechanism.
2Ease of operation
If a torsion structure is installed in the keyboard module, then the rotation function is provided, but the structure design of the second electronic module is limited
Solution Approach 1:
The torsion structure is extracted from the keyboard module and placed in the display module, removing the structural constraint from the second electronic module. This allows the second electronic module to be designed with heat-dissipating holes or other features without being limited by the presence of a torsion structure in the keyboard module.
Solution Approach 2:
The hinge mechanism transitions from a single-axis rotation to a dual-axis system, where the first axis enables rotation and the second axis provides synchronous spinning. This dimensional change allows the mounting portion to be positioned at a variable distance from the second axis, optimizing heat dissipation while maintaining rotation functionality.
3Temperature
If the distance between the second axis and the mounting portion is increased, then heat dissipation efficiency is improved, but the structural configuration becomes more complex
Solution Approach 1:
The mounting portion is designed with a variable distance from the second axis, allowing dynamic adjustment of the heat dissipation path. When the first electronic module rotates from the first position to the second position, the distance between the second axis and the mounting portion increases, creating a larger heat dissipation space without requiring a statically complex structure.
Solution Approach 2:
The system utilizes the rotation dimension to dynamically change the distance between the mounting portion and the second axis. This transforms a static structural constraint into a dynamic solution where heat dissipation efficiency is improved during the rotation operation without adding permanent structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the heat-dissipating efficiency of the second electronic module by increasing the distance between the mounting portion at the second position, allowing for better airflow and heat dissipation without the structural constraints of a torsion structure, thereby improving operational performance.
Implementation Method 1
The moving shaft has a gear-shaped segment and a fastening segment, and the gear-shaped segment is engaged with the mating segment of the fixing shaft. When the first electronic module is rotated from the first position to the second position, the moving shaft is rotated along the first axis and is synchronously spun along the second axis.
Implementation Method 2
The torsion structure is fixed on the fastening segment of the moving shaft. The torsion structure is configured to provide torque when the moving shaft is spun along the second axis.

AI summary
A clamshell-type electronic device includes a dual-axis hinge module, a first electronic module, and a second electronic module, the latter two of which are electrically connected to each other. The dual-axis hinge module includes a fixing shaft, a moving shaft parallel to and engaged with the fixing shaft, a moving frame fastened to the fixing shaft and the moving shaft, a torsion structure fixed on the moving shaft, and a fixing frame. No torsion structure is disposed on the fixing shaft. The moving frame is fixed on the first electronic module. The fixing frame has a connecting portion fixed on the fixing shaft and a mounting portion fixed on the second electronic module. The moving shaft can be rotated along the fixing shaft and can be synchronously spun, so that a distance between the moving shaft and the mounting portion can be changed.
