Low-Profile Kickstand Hinge With Dual-Axle Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kickstand hinges in dual display portable information handling systems are too thick, making it difficult to achieve a minimal height profile necessary for compact and efficient design.
Innovation Solution
A kickstand hinge system utilizing linear rail slots and multiple axles with integrated torque engines and spring mechanisms to enable a low-profile, dual pivot rotation, allowing the kickstand to extend and retract within a minimal height structure, providing a robust and space-efficient solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional kickstand hinge structures are used to provide sufficient support, then the kickstand has adequate structural strength, but the housing thickness increases to 3.8-4 mm
Solution Approach 1:
The kickstand hinge is divided into multiple functional segments: a kickstand member, a hinge member with rotating axis, and a support member with translating axis. This segmentation allows each component to be optimized independently, enabling the kickstand to achieve sufficient support strength while reducing overall housing thickness to 3mm or less through coordinated motion of the segmented components.
2Length of stationary object
If the kickstand hinge structure is reduced to 3mm or less thickness to fit dual display system, then the housing thickness is minimized, but the structural strength and support capability may be compromised
Solution Approach 1:
The kickstand hinge employs dynamic motion mechanisms where the hinge member rotates about a first axis and the support member translates along a second axis. This dynamic coordinated motion allows the kickstand to achieve extended positions with sufficient support capability while maintaining a retracted profile of 3mm or less thickness, resolving the contradiction between thin profile and structural strength.

AI summary
An information handling system kickstand hinge with a minimum profile transitions a kickstand between extended and retract positions with a first axle of a stand member that slides between forward and rear positions within guides or a rail housing and a second axle of the stand member that couples to the rail housing with riser arms disposed on opposing sides of the stand member. A first torque engine integrated in the riser housing resists sliding motion of a torque member engages with the first axle. A second torque engine integrated in the stand member resists rotation about the second axle. A spring aligned with the torque member biases the stand member towards the extended position to aid in extension of the kickstand from the retracted position.
