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

VSEngineering 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

Engineering Contradiction:
Improvecompatibility with different electronic devicesVSAvoidnumber of car charger adapters
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvesimplicity of charging operationVSAvoidcharging speed for multiple devices
Core Design Contradiction:
Ease of operationVSProductivity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvenumber of charging devicesVSAvoidantenna positioning flexibility
Core Design Contradiction:
Device complexityVSEase of operation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
