Battery Cell Gas-Test Adapter With Shutoff Valve for Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery cell testing technologies require both an adapter and a sensor to be mounted during transportation, causing inconvenience in handling and transportation.
Innovation Solution
An adapter with a movable valve body that can switch between open and closed states for gas flow, allowing the adapter to ensure gas tightness during transportation without needing a connected sensor, simplifying transportation by only requiring the adapter to be mounted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both adapter and sensor are mounted on battery cell during transportation, then gas tightness is ensured, but transportation convenience deteriorates
Solution Approach 1:
The adapter is segmented into a body portion and a movable valve portion that can be independently controlled. The valve portion includes a valve body that can move between open and closed positions, allowing the gas flow passage to be segmented into controllable sections. This enables the adapter to maintain gas tightness when connected to detection apparatus while allowing convenient transportation when the valve is closed and no connection is needed.
Solution Approach 2:
The adapter incorporates a movable valve body that can dynamically switch between open and closed states. The valve body is movably disposed on the adapter body and can be controlled to open the gas flow passage for testing or close it for transportation. This dynamic capability allows the system to adapt between different operational requirements without needing permanent sensor attachment.
2Adaptability or versatility
If sensor is connected to adapter during transportation, then gas detection capability is maintained, but device complexity increases
Solution Approach 1:
The detection capability is extracted from the transportation requirement. The adapter is designed so that the sensor or detection apparatus is not needed during transportation at all. The valve body can be closed to isolate the battery cell interior, making the detection apparatus optional and removable. This extracts the detection function from the mandatory transportation configuration, reducing system complexity during transit while maintaining adaptability when detection is actually needed.
Solution Approach 2:
The adapter serves multiple functions: it provides gas tight sealing when the valve is closed during transportation, and it enables gas detection when the valve is open and connected to detection apparatus. The same adapter structure handles both transportation and testing functions, eliminating the need for separate configurations or permanent sensor attachment, thereby reducing overall system complexity.
