Solution Overview
Problem
Conventional wireless chargers in vehicles often cause mobile devices to slide on charging surfaces during sharp turns, leading to distracted driving and potential accidents, and they either charge slowly or cause overheating due to power limitations.
Innovation Solution
A system featuring a tray with apertures for air suction to secure and cool mobile devices, combined with a wireless charger capable of high-power charging, which includes sensors for temperature monitoring and operational mode control to prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile device is placed on a horizontal surface in a vehicle, then the device can be easily accessible, but the device slides during sharp turns causing safety issues
Solution Approach 1:
The patent employs a suction device that creates negative pressure through apertures in the tray to generate a holding force on the mobile device. This pneumatic mechanism prevents lateral movement during sharp turns while keeping the device accessible on the horizontal tray surface, resolving the contradiction between ease of access and positional stability
2Productivity
If high-power wireless charging is used to charge the mobile device quickly, then charging speed is improved, but the device overheats
Solution Approach 1:
The suction device creates airflow through the apertures that passes over the mobile device during charging. This forced convection cooling removes heat generated by high-power wireless charging, enabling faster charging speeds without excessive temperature rise by actively managing thermal dissipation
3Reliability
If the mobile device is secured firmly to prevent sliding, then positional stability is improved, but the device cannot be easily removed
Solution Approach 1:
The suction force is dynamically controlled based on vehicle operation conditions. During sharp turns or acceleration, the suction device activates to prevent sliding. When the vehicle is stationary or operating normally, the suction force is reduced or deactivated, allowing easy removal of the device. This dynamic adjustment resolves the contradiction between firm securing and easy removal
