Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB connectors face issues with current limitations and power consumption from the data host when trying to charge portable electronic devices and exchange data simultaneously, potentially damaging the device or depleting the host's power.
Innovation Solution
A connector with a determining unit that selectively outputs data and power signals based on the connecting status of multiple power and data sources, using logic gates and MOSFETs to manage signal transmission and prevent overcharging, ensuring safe and efficient power delivery without draining the host's power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If USB connector is used to simultaneously charge and exchange data, then data transmission speed is improved, but power consumption from host and current stability deteriorate
Solution Approach 1:
The invention divides the power supply function from the data host by introducing a separate power bank connector. The USB connector handles only data transmission while the power bank connector independently manages power supply, eliminating the conflict between data speed and power consumption in the host system.
Solution Approach 2:
The power bank serves as an intermediary power source between the external power supply and the electronic device. It receives power from external sources and independently supplies power to the device during data transmission, preventing power consumption issues from affecting the host's data transmission capability.
2Productivity
If fast charging is enabled through USB connector, then charging speed is improved, but device safety deteriorates due to current limitations
Solution Approach 1:
The power bank incorporates built-in control circuitry that automatically detects the device's charging requirements and regulates power output accordingly. This self-regulating mechanism enables fast charging while inherently protecting the device from overcurrent and voltage fluctuations without requiring complex external protection circuits.
3Loss of energy
If power bank connector is added to separate power and data functions, then host power consumption is reduced, but device complexity increases
Solution Approach 1:
The power bank is designed with universal compatibility for various electronic devices and can function both as a portable power source and a data transmission hub. This multi-functionality justifies the added connector by providing multiple benefits: reducing host power consumption, enabling fast charging, and maintaining data transmission capability through a single integrated solution.
