Solution Overview

Problem

Conventional charging apparatuses with multiple interfaces can only charge energy storage devices using a single preset mode, failing to accommodate varying requirements and states of the devices, such as differing charging times based on characteristic parameters.

Innovation Solution

A charging apparatus with multiple interfaces and a control circuit that allows for two charging modes: a first mode where both interfaces are charged simultaneously and a second mode where charging is prioritized based on detected characteristic parameters, such as output voltage, to optimize charging time for each device, along with an adjustable setting apparatus for user-defined preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a charging apparatus has only one charging interface, then the device complexity is low, but the productivity is limited to charging only one energy storage apparatus at a time

Engineering Contradiction:
Improvecharging capacityVSAvoidnumber of charging interfaces
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The charging apparatus is divided into multiple independent charging interfaces (first charging interface and second charging interface), each capable of independently connecting to and charging an energy storage apparatus. This segmentation allows simultaneous charging of multiple devices while maintaining modular design that doesn't significantly increase overall system complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a charging apparatus uses a single preset charging mode for all interfaces, then the device complexity is low, but the adaptability to different energy storage apparatus states is poor

Engineering Contradiction:
Improvecharging mode flexibilityVSAvoidcontrol circuit complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The charging apparatus dynamically adjusts charging modes based on real-time detection of energy storage apparatus states. The control circuit can switch between first charging mode (simultaneous charging of all connected devices) and second charging mode (prioritized sequential charging) according to detected parameters such as charge levels and device characteristics, providing adaptability without requiring complex pre-programming for each scenario.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The charging apparatus automatically detects the state of connected energy storage apparatuses and autonomously determines the appropriate charging mode without requiring manual user input. The priority setting module detects characteristic parameters and automatically sets charging priorities, allowing the system to serve itself by making intelligent decisions based on real-time conditions.

Inventive Principle:
Principle #25Self-service

3Productivity

If all energy storage apparatuses are charged simultaneously in the first charging mode, then the productivity is high, but the loss of time occurs when some devices require longer charging durations

Engineering Contradiction:
Improvecharging throughputVSAvoidtotal charging time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The charging apparatus implements periodic switching between charging modes. In the second charging mode, devices are charged in a prioritized sequence rather than simultaneously, with the control circuit periodically monitoring charge states and switching power allocation. This periodic action ensures that devices requiring shorter charging times are completed first, reducing the overall time loss while maintaining high productivity through continuous operation.

Inventive Principle:
Principle #19Periodic action
