Wireless Charging Assembly With External Fan Cooling and IP Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless charging hosts and smartphones generate significant heat during charging, leading to ineffective cooling, which can cause smartphone breakdowns, especially during complex software operations.
Innovation Solution
A wireless charging assembly with a fan device positioned outside the housing, blowing airflow onto the supporting surface to cool both the charging host and electronic devices, while maintaining ingress protection by avoiding openings in the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the fan is disposed inside the accommodation space of the wireless charging host, then cooling is achieved, but openings or holes must be made on the housing which allows foreign materials to enter
Solution Approach 1:
The patent extracts the fan from the internal accommodation space of the wireless charging host and relocates it to an external position on the housing. This extraction eliminates the need for openings or holes in the housing structure, thereby maintaining the ingress protection rating and preventing foreign material entry. The fan is positioned externally but still achieves cooling functionality through the reflective plate mechanism.
2Ease of operation
If openings or holes are made on the wireless charging host to accommodate the fan, then the fan can be integrated, but foreign materials can enter into the wireless charging host
Solution Approach 1:
The fan is extracted from the internal accommodation space and repositioned externally on the housing. This extraction eliminates the need for openings or holes in the housing structure, thereby maintaining the ingress protection rating and preventing foreign material entry. The fan is positioned externally but still achieves cooling functionality through the reflective plate mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively cools electronic devices and the wireless charging host, preventing foreign material entry and maintaining desired ingress protection ratings, such as IP54, thereby enhancing device reliability and user experience.
Implementation Method 1
The fan is configured to blow an airflow to the supporting surface
