Dual Axis Stand Hinge for Portable Information Handling System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information handling systems typically sacrifice performance and ergonomics for portability, with limited display height and thermal management, leading to discomfort and constrained user interactions.
Innovation Solution
A portable information handling system that transforms from a clamshell to an all-in-one position by sliding the pivot axis towards the front side and extending a stand from the main housing to elevate the display, allowing adjustable vertical viewing and improved thermal transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display housing is rotated to a clamshell position with the main housing, then portability is improved, but display height and viewing ergonomics deteriorate
Solution Approach 1:
The display housing is designed to be dynamically reconfigurable between clamshell and all-in-one positions. The pivot axis can slide between front and rear sides of the main housing, and the stand can extend or retract, allowing the system to adapt its configuration based on whether portability or viewing ergonomics is the primary need.
Solution Approach 2:
The invention adds vertical dimensionality by introducing an extendable stand that raises the rear side of the main housing. This creates a new spatial dimension for display positioning, allowing the display to be elevated to eye level while maintaining the compact clamshell footprint on the desktop.
2Weight of moving object
If the display housing is rotated to a clamshell position, then portability is improved, but thermal management deteriorates
Solution Approach 1:
The stand mechanism is designed to be dynamically adjustable, allowing users to extend it when thermal management is needed and retract it when portability is the priority. This dynamic configuration change optimizes thermal dissipation by raising the housing to improve airflow and heat dissipation surface area.
3Device complexity
If the pivot axis is fixed at the rear side of the main housing, then structural simplicity is maintained, but display height adjustability deteriorates
Solution Approach 1:
The pivot axis is designed to slide between the front and rear sides of the main housing along a guideway, transforming from a fixed position to a movable one. This allows the display height to be adjusted by changing the pivot axis position, providing adaptability while maintaining relatively simple structural implementation through the guideway mechanism.
4Volume of moving object
If the stand is retracted, then device compactness is improved, but user interaction comfort deteriorates
Solution Approach 1:
The stand is designed as a dynamic component that can extend and retract based on operational needs. When user interaction comfort is prioritized, the stand extends to elevate the display to ergonomic viewing height. When compactness is needed, the stand retracts, allowing the device to maintain a small footprint while still providing comfort when deployed.

AI summary
A portable information handling system stand couples to a main housing lower surface with a dual axle hidden stand hinge that extends the stand parallel to the main housing lower surface with an initial synchronized opposing rotation of the axles by a predetermined amount, such as 45 degrees, and then rotates out a stand supporting end with rotation of one axle while the other axle remains stationary. Initial parallel extension of the stand reduces the amount of space in the main housing lower surface consumed by rotational movement of the stand to an extended position.
