Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for charging electronic devices in vehicles are inconvenient due to the need for multiple car charger adapters and sequential charging, which is inefficient and cumbersome.
Innovation Solution
A wireless power transmission system that uses a transmitter connected to a car lighter socket, with a cylindrical or rectangular housing integrating circuitry and an antenna array, allowing for simultaneous charging of multiple devices by positioning the antenna array in various locations within the vehicle, such as the sun visor or floor mats, and using Bluetooth to prioritize and manage charging requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple car charger adapters are used to charge different electronic devices, then each device can be charged with its specific adapter, but the user needs to carry and manage multiple adapters which increases complexity and inconvenience
Solution Approach 1:
The patent implements a universal wireless charging transmitter that can charge multiple types of electronic devices simultaneously through wireless power transmission. The system uses an antenna array that can form multiple independent pockets, each capable of charging a different device type (smartphones, tablets, laptops, etc.) without requiring separate adapters for each device category.
Solution Approach 2:
The patent combines multiple charging functions into a single wireless charging transmitter unit. Instead of using separate car charger adapters for different devices, the system merges all charging capabilities into one device that can handle multiple devices simultaneously through its array antenna technology.
2Ease of operation
If sequential charging is used through the car's cigarette lighter, then the charging operation is simple, but multiple devices cannot be charged simultaneously which reduces productivity
Solution Approach 1:
The patent segments the power transmission into multiple independent pockets, each capable of charging a different device simultaneously. The antenna array creates spatially separated energy zones that can independently charge multiple devices at the same time, maintaining operational simplicity while enabling parallel charging of multiple devices.
Solution Approach 2:
The system dynamically adjusts the antenna array configuration to form multiple pockets as needed. When multiple devices are detected, the system automatically creates multiple charging zones simultaneously, transitioning from single-device to multi-device charging mode without requiring manual reconfiguration or complex user intervention.
3Device complexity
If a single transmitter is used to charge multiple devices, then the number of adapters is reduced, but the transmitter needs to position antenna array in various locations to optimize pocket-forming which increases device complexity
Solution Approach 1:
The patent extends the charging system into the spatial dimension by using an array antenna that can form multiple three-dimensional pockets throughout the vehicle interior. This allows the single transmitter to charge devices located at various positions (front seats, rear seats, different heights) without requiring physical repositioning of the antenna array.
Solution Approach 2:
The system replaces mechanical antenna positioning with electronic beam forming and pocket formation. Instead of physically moving or reconfiguring the antenna array to charge different devices, the system uses electronic control to direct energy to specific spatial locations, maintaining a fixed antenna structure while achieving flexible multi-position charging capability.
