Solution Overview
Problem
First and second generation charging devices are limited by fixed output power ratings and pre-loaded charging protocols, requiring separate protocols for each device, which restricts adaptability and flexibility in charging capabilities.
Innovation Solution
A third generation charging system with hardware-defined attributes that can be reconfigured based on specific charging protocols received from the device to be charged, allowing for variable power output and functionality, including fast-charging, low-noise charging, and protocol updates via a charging-device-app, enabling compatibility with multiple devices without pre-loaded protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If charging devices use fixed output power ratings and pre-loaded charging protocols, then device compatibility is ensured, but adaptability and flexibility in charging capabilities are restricted
Solution Approach 1:
The charging device dynamically reconfigures its hardware-defined charging attributes based on the specific charging protocol received from the device being charged. The protocol received from the device dynamically changes the output power rating and charging characteristics, allowing the same charging device to adapt to different device types and charging requirements without pre-loaded protocols for each device type
Solution Approach 2:
The charging device changes its operational parameters (output power rating, voltage, current) based on the charging protocol received from the connected device. The hardware-defined charging attributes are reconfigured by receiving a specific charging protocol that defines the output power rating, enabling the charging device to provide different charging power levels and characteristics depending on the connected device's requirements
2Adaptability or versatility
If separate charging protocols are pre-loaded for each device type, then device compatibility is achieved, but manufacturing costs increase
Solution Approach 1:
The charging device is designed with universal hardware-defined charging attributes that can be reconfigured to support multiple device types and charging protocols. Instead of manufacturing different charging devices for different device types, a single universal charging device can adapt to various devices by receiving their specific charging protocols, thereby reducing manufacturing complexity and costs while maintaining broad device compatibility
3Reliability
If fixed output power ratings are used, then device reliability is ensured, but charging speed flexibility is limited
Solution Approach 1:
The charging device dynamically adjusts its output power rating based on the charging protocol received from the connected device. The hardware-defined charging attributes are reconfigured to match the device's specific charging requirements, allowing the charging speed to be optimized for each device type while maintaining safety through protocol-defined parameters
Solution Approach 2:
The charging device receives feedback from the connected device through the charging protocol exchange, which includes information about the device's charging capabilities and requirements. Based on this feedback, the charging device adjusts its output power rating to provide optimal charging speed while ensuring safety through the protocol-defined operating parameters
