Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems pose safety risks during maintenance due to potential human injury from negligence or malfunction of shut-off switches, necessitating automatic control mechanisms to enhance worker safety.
Innovation Solution
An energy storage system with enhanced safety features a control container and battery container, equipped with main and sub control units, sensors to detect door states, and switches that automatically shut off power when doors are open, ensuring safe operation by controlling the connection between lines and batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual shut-off switch operation is used for maintenance, then ease of operation is improved, but safety and reliability deteriorate due to human negligence or malfunction
Solution Approach 1:
The system performs automatic power cut-off by itself when maintenance conditions are detected, eliminating the need for manual operation. The control unit automatically receives maintenance information and triggers the shut-off switch, making the system self-protecting without human intervention.
Solution Approach 2:
The system receives maintenance information as feedback and automatically responds by cutting off power. This closed-loop feedback mechanism ensures that maintenance operations trigger the appropriate safety response without relying on manual switch operation.
2Reliability
If automatic control mechanism is implemented, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it manages normal battery operations, receives maintenance information, automatically triggers power cut-off, and provides safety protection. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The patent combines the control unit, maintenance information receiver, and automatic shut-off trigger into an integrated system. The control unit and shut-off mechanism are merged to work as a unified safety system, reducing overall device complexity while maintaining automatic protection capabilities.
