Rotatable Data Card Asymmetric Shaft Prevents Perpendicular Gravity Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rotatable data card's heat dissipation is compromised when the data card body is unintentionally rotated perpendicular to the direction of gravity, affecting its cooling efficiency.
Innovation Solution
A rotatable data card design featuring a rotating shaft assembly with teeth on the rotating shaft and fixed fluted disk, ensuring the angle between the data card body and USB connector is never 180 degrees, thereby preventing perpendicular orientation to gravity, which enhances heat dissipation by maintaining optimal angles for thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the data card body is made rotatable to improve heat dissipation, then heat dissipation effect is improved, but the data card body may unintentionally rotate perpendicular to gravity direction, worsening heat dissipation effect
Solution Approach 1:
The rotating shaft and fixed fluted disk are designed with asymmetric tooth configurations where the number of teeth and their angular positions are deliberately made unequal. This asymmetric design ensures that when the data card body rotates, it cannot achieve a perpendicular orientation (180-degree angle) relative to the USB connector, thereby preventing the worst-case heat dissipation scenario while maintaining rotation capability for thermal management.
2Reliability
If the rotating shaft and fixed fluted disk are engaged with teeth to prevent perpendicular rotation, then heat dissipation stability is improved, but the device complexity increases
Solution Approach 1:
The fixed fluted disk acts as an intermediary component between the rotating shaft and the external environment. By placing the tooth engagement mechanism inside the rotating shaft casing rather than on the external surface, the patent achieves the anti-perpendicular function through an internal intermediary structure, minimizing external complexity while maintaining the required functional constraint.
