Dynamic Air Diverter for Laptop Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with static airflow diverters fail to adapt airflow direction based on the position of housing parts, leading to undesired user exposure to heated exhaust air when the device is in different configurations.
Innovation Solution
A portable electronic device with a dynamic air diverter that moves based on the rotational position of the display housing relative to the base portion, allowing airflow to be redirected through different openings to prevent user exposure and enhance cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stationary airflow diverter structure is used, then the device structure is simple and manufacturing is easy, but the airflow direction cannot be adjusted based on device configuration, causing heated air to flow toward the user
Solution Approach 1:
The patent applies the dynamics principle by making the airflow diverter movable rather than stationary. The diverter is coupled to the display housing and automatically changes position based on whether the display housing is in an open or closed configuration. This allows the airflow direction to adapt dynamically to different device states, resolving the contradiction between adaptability and structural simplicity.
2Object-affected harmful factors
If the display housing is in a closed configuration, then the device is compact, but the stationary diverter directs heated air toward the display housing creating user exposure risk
Solution Approach 1:
The patent applies preliminary anti-action by positioning the movable diverter to proactively block or redirect heated airflow away from the display housing before the user can be exposed. When the display housing is closed, the diverter automatically adjusts to prevent hot air from entering the display area, thus preventing harm before it occurs.
3Ease of operation
If a movable airflow diverter is implemented, then airflow direction can be optimized for different configurations, but the device complexity increases
Solution Approach 1:
The patent applies self-service by designing the airflow diverter to automatically adjust based on the display housing position without requiring external control systems. The diverter is mechanically coupled to the display housing, so it self-adjusts as the housing opens or closes, improving cooling efficiency while minimizing the added complexity.

Function Achieved in This Case
The dynamic air diverter effectively directs heated exhaust air away from the user and improves cooling efficiency by altering airflow paths based on the device's configuration, reducing the risk of user injury and optimizing heat dissipation.
Implementation Method 1
a fan configured to move the heated air away from the heat-generating components and toward an opening in the electronic device

AI summary
A portable electronic device is disclosed. The portable electronic device may include a laptop computing device that includes a base portion and a display housing rotationally coupled to the base portion. The base portion includes a fan designed to drive heated air out of the base portion, thus cooling the portable electronic device. A dynamic (movable) air diverter is integrated into the base portion near the fan's outlet. The air diverter is designed to direct airflow from the fan outlet. Moreover, the air diverter can be repositioned by, for example, rotating the display housing relative to the base portion. As a result of the repositioned air diverter, the airflow from the fan outlet is redirected out of the portable electronic device through a different location. The air diverter can be positioned in different discrete locations, or alternatively, can move continuously with the rotational movement of the display housing.
