Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional distribution boards face challenges in securing sufficient power during power outages and efficiently utilizing stored power, leading to limitations in operation and battery degradation.
Innovation Solution
A distribution board with a pack housing unit for a battery pack and a charge controller that converts AC power to DC power for charging, allowing for removable battery packs and switching between grid connection and self-sustained operation modes, along with a discharge controller for emergency loads and a display for power level monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery pack is installed to enable self-sustained operation during power outage, then power supply capability during outage is improved, but device complexity increases due to additional components and control requirements
Solution Approach 1:
The distribution board integrates the battery pack housing, charge controller, and power management functions into a unified system. The pack housing unit combines battery accommodation, charging control, and power distribution capabilities, eliminating the need for separate standalone devices and reducing overall system complexity while maintaining self-sustained operation capability.
Solution Approach 2:
The distribution board is designed to perform multiple functions: normal power distribution from the power system, charging the battery pack from AC power, and supplying power to loads during power outages. The charge controller and connecting unit enable the system to operate in both grid-connected and standalone modes, providing universal power supply capability across different operating conditions.
2Stability of the object's composition
If the battery pack is permanently integrated into the distribution board, then system stability is improved, but adaptability decreases due to inability to remove or relocate the battery
Solution Approach 1:
The battery pack system is segmented into a removable battery pack unit and a distribution board with a pack housing unit. The connecting unit provides detachable electrical connections, allowing the battery pack to be separated from the distribution board. This segmentation enables the battery to be relocated or replaced while maintaining stable electrical connections during operation, balancing system stability with operational adaptability.
3Productivity
If the battery pack supplies power to multiple devices simultaneously, then power utilization efficiency is improved, but control complexity increases due to multiple connection and disconnection operations
Solution Approach 1:
The connecting unit is designed with universal connectivity capability, allowing the battery pack to simultaneously supply power to the distribution board and external devices. The single connecting unit handles multiple power distribution paths, enabling the battery to serve both internal system needs and external device requirements without requiring separate connection mechanisms for each device.

AI summary
A distribution board includes: a pack housing unit which houses a battery pack and includes a connecting unit; and a charge control unit. The battery pack includes a connecting terminal unit for charge and discharge of power and can supply power to the distribution board and another device different from the distribution board. The connecting unit is connectable to and disconnectable from the connecting terminal unit. The charge control unit converts AC power supplied from a power system into DC power, and supplies the DC power to the battery pack housed in the pack housing unit to charge the battery pack.
