Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of ensuring safety during battery testing, particularly in the context of power testing and high-voltage insulation testing, where battery fires pose a significant hazard to personnel and equipment.
Innovation Solution
A device with a transport system, interface for power supply, and a fire protection hood that can be lowered to contain and shield a battery in case of fire, allowing safe transport of the battery to a protective chamber or outside area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery is subjected to power testing with high voltage and current, then the functionality and reliability of the battery can be verified, but the risk of fire and smoke development increases significantly
Solution Approach 1:
The testing system is segmented into distinct functional zones: a test position for battery testing, a protective chamber for containing hazards, and a transport system for moving batteries between zones. This spatial segmentation allows reliable testing to occur while isolating fire and smoke hazards in a dedicated containment area.
Solution Approach 2:
The transport system acts as an intermediary mechanism that safely transfers batteries from the test position to the protective chamber. This intermediary system enables the separation of testing operations from hazard containment, allowing reliability verification while minimizing exposure to fire and smoke risks.
2Object-affected harmful factors
If a battery catches fire during testing, then immediate containment is required, but the testing process must be interrupted
Solution Approach 1:
The protective chamber is pre-positioned and ready to receive batteries that may catch fire. The transport system is pre-configured to quickly move batteries from the test position to the protective chamber. This preliminary preparation ensures that when fire occurs, containment can begin immediately without interrupting the overall testing workflow, as the next battery can be prepared in advance.
Solution Approach 2:
The transport system enables rapid transfer of batteries through the hazardous zone from the test position to the protective chamber. This quick transit minimizes the time a burning battery is exposed to the testing environment and surrounding equipment, allowing fire containment to be achieved swiftly while maintaining testing productivity by quickly moving to the next test subject.
3Object-affected harmful factors
If a protective chamber with smoke gas extraction is used, then fire and smoke can be contained, but the device complexity increases
Solution Approach 1:
The protective chamber serves multiple functions: it contains fire, extracts smoke gases, and can serve as a temporary holding area for batteries. The transport system also functions both as a battery carrier and as a hazard isolation mechanism. This multi-functionality reduces the need for separate dedicated components for each safety function, thereby limiting the increase in device complexity.
