Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wireless charging socket charges multiple devices simultaneously without differentiation, then all devices can be charged, but power distribution is inefficient and cannot meet individual device needs
Solution Approach 1:
The patent segments the wireless charging system into multiple independent charging zones or endpoints, each capable of individually identifying and managing specific devices. This allows the system to treat each device separately rather than as a group, enabling differentiated power distribution while maintaining multi-device support.
Solution Approach 2:
The system implements feedback mechanisms where the wireless charging socket continuously monitors device parameters (charge status, power needs, device type) and adjusts power distribution in real-time based on this feedback. This enables dynamic optimization of charging efficiency for each device while adapting to changing conditions.
2Reliability
If a charger is dedicated to one system, then charging is reliable for that specific device, but it cannot charge other device types
Solution Approach 1:
The patent creates a universal wireless charging platform that can identify and charge multiple types of devices (smartphones, tablets, laptops, wearables) through a single socket. The system uses device identification protocols to recognize different device types and applies appropriate charging parameters for each, achieving both reliability and versatility.
Solution Approach 2:
The system dynamically changes charging parameters (voltage, current, power level) based on the identified device type and its current charge state. This allows a single charger to adapt its output to match the specific requirements of different devices, maintaining reliable charging across diverse device types.
3Ease of operation
If power is distributed equally to all connected devices, then simple power allocation is achieved, but devices with higher charge needs do not receive priority
Solution Approach 1:
The patent implements dynamic power allocation where the system continuously monitors device charge levels, power consumption rates, and charge needs, then adjusts power distribution in real-time. Devices with higher charge needs or faster discharge rates automatically receive more power, while fully charged or low-power devices receive less, optimizing overall charging efficiency without complex manual intervention.

AI summary
In one or more embodiments, one or more systems, methods, and/or processes may supply, via wireless charging endpoints, more power to a first device of multiple devices than to a second device of the multiple devices. While the multiple devices are wirelessly coupled to the wireless charging endpoints, current data, from each of the multiple devices may be received. If historical data of each of the multiple devices is available via a storage medium: the current data may be compared with the most recently stored historical data, and based on comparing the current data with the most recently stored historical data, more power may be supplied to another device of the multiple devices than to at least one of the first device and the second device. If the historical data is not available, the current data may be stored, via the storage medium, as the most recent historical data.
