Door Applique Wireless Charger for Dead Remote Key Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may be unable to unlock their vehicles if their remote unlocking device, such as a smartphone with PAAK technology, has a dead battery, especially in situations where there is no access to a charging mechanism.
Innovation Solution
A vehicle is equipped with a wireless charger integrated into a door applique that can charge a remote unlocking device for a limited time, preventing unauthorized battery drain and ensuring the device can power on and unlock the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless charger is provided to charge the remote unlocking device, then the device can be powered on and unlock the vehicle even with a dead battery, but the vehicle battery may be excessively drained
Solution Approach 1:
The wireless charger operates in periodic intervals rather than continuously. The controller activates the wireless charger for specific time periods when a remote unlocking device is detected, then deactivates it after a predetermined time interval. This periodic operation allows the remote device to be charged sufficiently for unlocking while preventing excessive drainage of the vehicle battery.
Solution Approach 2:
The wireless charger provides partial charging action rather than full continuous charging. By limiting the charging duration to a predetermined time period, the system provides just enough energy for the remote device to power on and unlock the vehicle, without providing excessive energy that would unnecessarily drain the vehicle battery.
2Adaptability or versatility
If the wireless charger operates continuously, then the remote unlocking device can always be charged, but unauthorized users may drain the vehicle battery
Solution Approach 1:
The controller monitors the charging process and automatically deactivates the wireless charger after a predetermined time period. This feedback mechanism ensures that even if an unauthorized user places a device on the charging surface, the system will stop charging after the time limit, preventing excessive battery drainage while still providing charging service to legitimate users who need to unlock the vehicle.
