Segmented Cooling Kickstand for IHS Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable Information Handling Systems (IHSs) face temperature issues due to heat dissipation from components exceeding thermal specifications, which can impact performance and efficiency.
Innovation Solution
A fragmented cooling kickstand system with strategically located vents in the housing, which adjusts airflow by rotating the kickstand to either block or uncover vents, enhancing air intake and airflow around fans and heat pipes, thereby regulating temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the kickstand is kept closed to maintain a compact profile, then the device form factor is improved, but airflow to cooling vents is blocked causing increased temperature
Solution Approach 1:
The kickstand is divided into multiple segments that can be independently positioned. This segmentation allows the kickstand to be configured in different states: closed for compact storage, partially open to allow airflow to specific vents, or fully open for maximum cooling, thus resolving the contradiction between maintaining compact shape and enabling temperature control
Solution Approach 2:
The kickstand is designed with dynamic positioning capability, allowing it to be adjusted to different angles and positions. This dynamic feature enables the kickstand to adapt between blocking vents (when closed) and uncovering vents (when opened), providing flexible control over airflow and temperature based on operational requirements
2Temperature
If the kickstand is opened to uncover vents for cooling, then temperature control is improved, but the compact profile is compromised
Solution Approach 1:
By segmenting the kickstand structure, the invention enables selective opening where only the necessary portion is opened to uncover vents for cooling, while other segments remain closed to maintain the compact profile, thus achieving temperature control without fully compromising the compact shape
Solution Approach 2:
The kickstand is designed with local quality variations, where specific segments have different functions: some segments are designed to block vents when closed, while others are designed to uncover vents when opened. This local differentiation allows targeted cooling at specific areas without requiring the entire kickstand to be opened, preserving the compact profile where not needed
3Ease of manufacture
If traditional cooling vents are used without kickstand integration, then manufacturing simplicity is maintained, but cooling effectiveness during transport and storage is reduced
Solution Approach 1:
The invention merges the kickstand structure with the cooling vent system by integrating vents into the kickstand itself. This merging allows the kickstand to serve dual purposes: providing structural support/positioning and controlling airflow to cooling vents, thereby improving cooling effectiveness during transport and storage while maintaining manufacturing simplicity through the integrated design
