Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply redundancy systems are limited in size due to the need for separate components connected by thick wire harnesses, and lack adequate protection for control circuits.
Innovation Solution
A power supply redundancy system with a twin battery and integrated control board, where the main battery, sub-battery, and switching unit are housed together, allowing for power supply redundancy and enhanced protection through dual power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main battery, sub-battery, and switching unit are connected by thick wire harnesses, then reliable power supply is ensured, but the system size increases and close disposition becomes difficult
Solution Approach 1:
The patent merges the main battery, sub-battery, and switching unit into a single integrated housing structure. This consolidation eliminates the need for external thick wire harnesses to connect separate components, thereby reducing overall system volume while maintaining reliable power supply through internal electrical connections.
Solution Approach 2:
The housing structure serves multiple functions: it provides mechanical protection for the batteries and switching unit, acts as a structural framework for internal electrical connections, and enables close disposition of components. This multi-functionality reduces the need for additional connecting structures, thereby reducing system size.
2Device complexity
If the control circuit is supplied with power from inside the battery pack, then the configuration is simplified, but redundant protection cannot be executed when power supply to the control circuit fails
Solution Approach 1:
The patent segments the power supply system into two independent power sources (main battery and sub-battery) that can independently supply power to the control circuit. This segmentation allows the control circuit to receive power from either source, providing redundant protection while maintaining a relatively simple overall configuration.
Solution Approach 2:
The patent implements beforehand cushioning by providing a standby power source (sub-battery) that can take over power supply to the control circuit if the main power source fails. This preparatory arrangement ensures continuous operation and protection without adding significant complexity to the system.
3Ease of manufacture
If separate components are used for main battery, sub-battery, and switching unit, then modular assembly is enabled, but close disposition is limited due to wire harness bending requirements
Solution Approach 1:
The patent combines the main battery, sub-battery, and switching unit into a single housing structure, enabling close disposition of components without the constraints of wire harness bending. This merging maintains ease of manufacture through standardized housing and internal component mounting while eliminating the need for long external connections.

AI summary
A power supply redundancy system includes a main battery that supplies power to a first load unit and a second load unit, a sub-storage that supplies power to at least the second load unit, a switching unit that switches a power supply path from the main battery and the sub-storage to the first load unit and the second load unit, a control board on which a switching control unit is mounted, the switching control unit for switching and controlling the switching unit, and a housing that accommodates at least the main battery, the sub-storage, and the switching unit. The control board is operable by receiving power supply from both the main battery and the sub-storage.
