Adjustable Torsional Force Hinge Module for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinge modules in portable electronic devices, such as notebook computers, face challenges in providing both ease of operation and structural stability due to a fixed torsional force that is inadequate for smooth opening and sufficient for preventing vibrations.
Innovation Solution
A hinge module design featuring a first and second bracket, a pivot assembly, a pressing component, and an adjusting structure, where the pressing component continuously presses a sliding portion along a sliding slot, allowing for adjustable torsional force through a lock assembly, enabling varying pressing forces as the brackets rotate, thus ensuring non-constant torsional force and enhanced usability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the hinge module uses a fixed torsional force, then the structural stability is improved, but the convenience of operation deteriorates
Solution Approach 1:
The hinge module transitions from a fixed torsional force system to a dynamic system where the pressing component can adjust its position along the sliding slot. This allows the torsional force to vary continuously based on the rotation angle, providing small force during opening and large force for stability when closed
Solution Approach 2:
The invention changes the parameter of torsional force from a fixed value to a variable that changes with the rotation angle. By adjusting the position of the pressing component along the sliding slot, the magnitude of the torsional force is dynamically adjusted to meet different operational requirements
2Stability of the object's composition
If the hinge module provides large torsional force to prevent vibrations, then the structural stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The system dynamically adjusts the torsional force magnitude based on the operational phase. During opening operation, the pressing component is positioned to provide small force; when closed, it automatically provides large force for vibration prevention
Solution Approach 2:
The sliding slot is pre-configured with a specific geometry that determines the pressing force at different angles. The structure is designed in advance so that when the bracket rotates to different positions, the pressing component automatically experiences the appropriate force magnitude
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
The hinge module achieves both convenience in operation and structural stability by adjusting torsional force based on the position of the sliding portion, facilitating easy opening and preventing unexpected vibrations, thereby improving user experience and device stability.
Implementation Method 1
the pressing component presses the first sliding portion by the adjusting structure. When the first bracket and the second bracket rotate relative to each other, the first sliding portion slides along the first sliding slot, and the hinge module generates a torsional force by continuously pressing the first sliding portion by the pressing component

AI summary
A hinge module includes a first bracket, a second bracket, a pivot assembly, a pressing component and an adjusting structure. The first bracket has at least one first sliding slot. The first bracket and the second bracket are pivoted to each other by the pivot assembly, wherein the pivot assembly has a first sliding portion that is slidably disposed in the first sliding slot. The pressing component is connected to the first bracket and the first sliding portion. The adjusting structure is connected to the pressing component that presses the first sliding portion by the adjusting structure. When the first bracket and the second bracket rotate relative to each other, the first sliding portion slides along the first sliding slot, and the hinge module generates a torsional force by continuously pressing the first sliding portion by the pressing component. In addition, an electronic device including the hinge module is provided.
