Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple charging ports are added to charge multiple devices simultaneously, then the charging capacity and versatility are improved, but the overall size of the charger increases
Solution Approach 1:
The patent combines multiple charging ports into a single integrated charger unit, merging the functionality of multiple individual chargers into one device. This allows simultaneous charging of multiple devices while maintaining a compact form factor that does not significantly increase in size compared to single-port chargers.
Solution Approach 2:
The charger is designed with universal compatibility to charge multiple types of devices simultaneously through multiple ports. Each port can independently charge different devices, providing multi-functional capability without requiring separate dedicated chargers for each device type.
2Productivity
If multiple batteries are charged at the same time, then the charging capacity is improved, but the power consumption increases and generates excessive heat
Solution Approach 1:
The charger implements periodic or sequential charging cycles rather than continuous simultaneous charging at full power. The charging current is dynamically adjusted and distributed across ports in a controlled manner, reducing peak power consumption and heat generation while still providing simultaneous charging capability.
Solution Approach 2:
The charger dynamically changes charging parameters such as current and voltage distribution across different ports based on real-time conditions. By adjusting these parameters, the system optimizes power consumption and heat dissipation while maintaining the ability to charge multiple batteries simultaneously at appropriate rates.

Implementation Method 1
The OVA reduces the power consumed by the CRC circuit by depressing a voltage at the input of the CRC so that the CRC output voltage is sufficient to charge the rechargeable battery when it is discharged.
Implementation Method 2
A battery charger has at least one charging port for a device having a rechargeable battery, and a charging circuit
Data Source
AI summary
A battery charger has at least one charging port for a device having a rechargeable battery, and a charging circuit. The charging circuit includes a DC-DC circuit, a current regulation circuit (CRC) and an output voltage adjustment circuit (OVA), the charging port being electrically connected to an output of the CRC. The OVA reduces the power consumed by the CRC circuit by depressing a voltage at the input of the CRC so that the CRC output voltage is sufficient to charge the rechargeable battery when it is discharged. The OVA circuit increases the input voltage of the CRC as the rechargeable battery is charged.
