Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the test device is manually adjusted for each battery module type, then the testing accuracy is maintained, but the adjustment time and productivity are reduced
Solution Approach 1:
The system pre-stores module information (arrangement patterns, cell types, specifications) in a database before actual testing. When a battery module needs testing, the system automatically retrieves the corresponding test parameters and probe card configurations from the database, eliminating the need for manual adjustment and information re-entry, thus maintaining testing accuracy while significantly improving adjustment efficiency
Solution Approach 2:
The test device is equipped with an automatic control system that autonomously adjusts probe card positions and selects test parameters based on retrieved module information. The system performs self-adjustment without human intervention, maintaining measurement precision through automated control while dramatically improving productivity by eliminating manual adjustment operations
2Adaptability or versatility
If the probe card adjustment assembly is designed for high adaptability to different battery modules, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The probe card adjustment assembly employs a universal design with programmable positioning mechanisms that can accommodate multiple battery module types through software configuration rather than hardware redesign. The system uses standardized interfaces and modular components that can be reconfigured for different module specifications, achieving high versatility while keeping the physical structure relatively simple and maintainable
3Measurement precision
If multiple probe cards are moved individually during battery module switching, then the positioning precision is maintained, but the switching time increases
Solution Approach 1:
The system merges the movement control of multiple probe cards into a coordinated operation. When switching between battery modules, the probe cards are positioned and adjusted in a coordinated manner using shared positioning mechanisms and synchronized control algorithms, maintaining individual positioning precision while reducing overall switching time through combined operations rather than sequential individual adjustments
