Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional battery cell manufacturing process is used without a proper degassing device, then the manufacturing process is simple, but gas accumulation causes battery case deformation and electrode disconnection, deteriorating production quality
Solution Approach 1:
The patent extracts the degassing function from the conventional manufacturing process by introducing a dedicated degassing device with needle insertion mechanisms and gas extraction pathways, separating the gas removal function from the charging process to prevent quality deterioration
Solution Approach 2:
The patent introduces intermediary components including a degassing device, needle insertion mechanism, and gas extraction pathways that mediate between the battery cell and the external environment, enabling controlled gas removal without direct intervention in the charging process
2Reliability
If a degassing device is added to remove gases during charging, then production quality improves, but the equipment structure becomes more complex and installation space increases
Solution Approach 1:
The patent implements nesting by placing the degassing device and its components within or around the existing charging equipment structure, with needle insertion mechanisms that integrate into the battery cell assembly process, thereby minimizing additional installation space while maintaining improved production quality
Solution Approach 2:
The patent utilizes vertical space and three-dimensional arrangement by positioning the degassing device above or beside the battery cell, with movable needles that extend vertically into the cell, transforming the spatial arrangement from horizontal to vertical to reduce footprint area
3Area of stationary object
If the degassing device is arranged in a vertical direction, then installation space is minimized, but the movement mechanism becomes more complex
Solution Approach 1:
The patent employs dynamic mechanisms including movable needles that can extend and retract, and a pivot hinge assembly that enables rotational movement, transforming the static structure into a dynamic system that achieves vertical arrangement while managing movement complexity through controlled motion
Solution Approach 2:
The patent implements preliminary action by pre-positioning the degassing device and needle insertion mechanism in a retracted or prepared state before the degassing operation, with the pivot hinge assembly pre-configured to enable the required movement path, thereby simplifying the actual degassing motion sequence
