Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional battery diagnostic techniques are used, then measurement of physical characteristics can be obtained, but scalability and consistency across different battery types and geometries cannot be achieved
Solution Approach 1:
The holder system is designed as a universal platform that can accommodate multiple sensor types (strain gauges, temperature sensors, pressure sensors) and adapt to different battery geometries (cylindrical, pouch, prismatic) through interchangeable components and adjustable fixtures, enabling a single system to perform diverse diagnostic functions across various battery types
2Measurement precision
If physical contact between sensors and battery surfaces is maintained, then accurate measurement can be achieved, but consistency across different battery geometries deteriorates
Solution Approach 1:
The holder system incorporates adjustable and reconfigurable components that can dynamically adapt to different battery geometries, allowing the mechanical contact interface to be modified according to the specific battery shape being tested, thereby maintaining measurement precision across diverse battery types
3Reliability
If multiple sensor types are used for comprehensive battery diagnostics, then measurement accuracy improves, but device complexity increases
Solution Approach 1:
The holder system integrates multiple sensor types (strain gauges, temperature sensors, pressure sensors) into a single unified platform with common mounting mechanisms and signal processing interfaces, allowing comprehensive battery diagnostics to be achieved through one integrated system rather than separate standalone devices
