Adjustable Hinge Module with Retractable Shaft for Tilt Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no universal hinge that can effectively compensate for various tilt forces across different information handling systems, as existing hinges require individual adjustments with different torsion spring forces and frictional forces to manage tilt forces specific to each system.
Innovation Solution
A hinge module with a retractable shaft and adjustable torsion spring mechanism, allowing the hinge assembly to adjust between two positional states to accommodate different tilt forces, featuring a compressible pin, ratchet stopper, and adjustable shaft to apply varying hinge forces, ensuring stability across different display sizes and tilt thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual hinges with different torsion spring forces are used for each display size, then tilt force compensation is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The hinge assembly is designed as a universal mechanism that can accommodate multiple display sizes and tilt force requirements through a single standardized design. The retractable shaft mechanism allows the same hinge to function with different torque characteristics by adjusting shaft extension, eliminating the need for multiple specialized hinges for different display configurations.
Solution Approach 2:
The hinge incorporates a dynamic retractable shaft mechanism that can change its effective length and torque characteristics during operation. The shaft can be extended or retracted to adjust the mechanical advantage and torsion spring force distribution, allowing the hinge to adapt to different tilt force requirements without changing the basic hinge structure.
2Adaptability or versatility
If adjustable torsion spring forces are implemented, then adaptability to different tilt forces is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism is divided into discrete segments or positions along the retractable shaft. The shaft includes multiple engagement points or detents that correspond to different torque settings, allowing stepwise adjustment rather than continuous variation. This segmented approach simplifies the control mechanism while providing adequate adaptability for different display sizes and tilt force requirements.

Function Achieved in This Case
The hinge module provides adjustable tilt resistance, preventing tilting for both low and high tilt forces, accommodating different display sizes by adjusting the retractable shaft and torsion spring forces, thus offering a versatile solution for diverse information handling systems.
Implementation Method 1
a compressible pin such that when the compressible pin is positioned within the first pair of recesses, the retractable shaft is in the first position, and when the compressible pin is positioned with the second pair of recesses, the retractable shaft is in the second position
Implementation Method 2
a torsion spring positioned around the hinge assembly; a ratchet stopper coupled to the torsion spring; and an adjustable shaft, wherein a first end of the adjustable shaft is positioned within the hollow portion of the retractable shaft, the adjustable shaft including a second end that engages the ratchet stopper to adjust a state of the torsion spring such that when the adjustable shaft is in a first position with respect to the ratchet stopper, the torsion spring applies a first hinge force to the base bracket, and when the adjustable shaft is in a second position with respect to the ratchet stopper, the torsion spring applies a second hinge force to the base bracket
