Transformative Cable Management for Ergonomic Display Pivot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information handling systems sacrifice performance and ergonomics for portability, with limited display size and keyboard space, leading to discomfort and reduced interaction efficiency due to thermal management issues 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
1Ease of operation
If the system transforms to an all-in-one position with extended stand, then ergonomics and thermal management are improved, but device complexity increases
Solution Approach 1:
The hinge assembly enables dynamic reconfiguration of the display housing relative to the main housing, allowing the system to transform between clamshell and all-in-one positions. The pivot axis can slide along the main housing to adjust the display position, providing adaptive ergonomics while maintaining a relatively simple mechanical structure through controlled movement rather than multiple discrete components.
2Temperature
If the system transforms to an all-in-one position, then thermal management is improved, but device complexity increases
Solution Approach 1:
The system dynamically adjusts its configuration to optimize thermal management. In all-in-one position, the display housing is elevated and positioned to improve airflow and heat dissipation from the main housing. This dynamic reconfiguration allows passive thermal management enhancement without requiring active cooling components or complex thermal control systems.
Solution Approach 2:
The transformation to all-in-one position utilizes vertical space by elevating the display housing above the main housing. This dimensional change creates improved airflow paths and thermal convection currents, enhancing heat rejection without requiring additional thermal management components or increasing device complexity.
3Weight of moving object
If the system maintains clamshell mode for portability, then mobility is maintained, but ergonomics and thermal management are compromised
Solution Approach 1:
The system provides dynamic reconfigurability, allowing users to switch between clamshell mode for portability and all-in-one mode for improved ergonomics. The hinge assembly with sliding pivot axis enables smooth transformation between configurations, making the system adaptable to different usage scenarios without sacrificing mobility when needed.

AI summary
A portable information handling system moves a display pivot axis between a main housing front and rear side with a display cable communicating visual information between the display and main housing. A display cable manager regulates a length of the display cable by wrapping the display cable about a spool biased to retract the display cable.
