Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless charging efficiency is reduced due to heat generated by both the charger and mobile devices, which affects charging performance.
Innovation Solution
A wireless charging device with a casing that includes an air inlet and outlet, a fan, and support surfaces for electronic devices, where the fan sucks air in through the inlet, cooling the devices and the charging module by directing airflow through the interior space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless charging is performed, then charging function is provided, but heat is generated reducing charging efficiency
Solution Approach 1:
The air inlet is positioned between the placement regions so that air is drawn in before entering the interior space, creating a pre-cooling effect on the wireless charging module before full charging operation begins
Solution Approach 2:
Air is introduced as an intermediary cooling medium between the wireless charging module and the electronic devices, flowing through the interior space to absorb heat and maintain optimal operating temperatures
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
Maintains optimal temperatures for both electronic devices and the wireless charging module, enhancing charging efficiency by effectively dissipating heat.
Implementation Method 1
The fan is disposed in the interior space and configured to suck air into the interior space through the air inlet and blow air out of the interior space through the air outlet
Implementation Method 2
when the fan sucks air into the interior space through the air inlet, the airflow can firstly pass by the electronic devices to cool the electronic devices, and then the airflow enters into the interior space to cool the wireless charging module

AI summary
A wireless charging device (1) is configured to charge two electronic devices (2). The wireless charging device includes a casing (10), a wireless charging module (20) and a fan (30). The casing has an interior space (113), an air inlet (13), an air outlet (1115) and a support surface (1121). The air inlet and the air outlet are in fluid communication with the interior space. The support surface faces away from the interior space, the support surface has two placement regions (1121a), the air inlet is located between the two placement regions, and the two placement regions are configured for the two electronic devices to be placed thereon. The wireless charging module is disposed in the interior space and corresponds to the two placement regions. The fan is disposed in the interior space and configured to suck air into the interior space through the air inlet and blow air out of the interior space through the air outlet.
