Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If identification components such as resistors and IC chips are attached to a battery, then battery type identification can be performed, but the cost increases and the components may be imitated leading to incorrect identification
Solution Approach 1:
The invention extracts the identification function from external components (resistors and IC chips) and integrates it into the battery's inherent electrical characteristics. By measuring the internal resistance that naturally exists in the battery structure, the system eliminates the need for separate identification components while maintaining accurate battery type determination.
Solution Approach 2:
The battery's own internal resistance serves as the identification marker. Instead of requiring external components to provide identification information, the invention utilizes the battery's intrinsic electrical property (internal resistance) to automatically indicate its type, making the battery self-identifying without additional parts.
2Measurement precision
If identification components are attached to a battery, then battery type can be determined, but the cost of the battery increases
Solution Approach 1:
The invention removes the need for expensive identification components (resistors and IC chips) by extracting the identification function from external parts and utilizing the battery's inherent internal resistance characteristic, thereby reducing manufacturing costs while maintaining identification capability.
Solution Approach 2:
The invention replaces expensive, complex identification components with a simple, cost-free measurement of the battery's natural internal resistance. This approach uses no additional materials, effectively reducing the identification system to zero material cost while maintaining functional equivalence.
3Measurement precision
If external identification components are used, then battery type can be identified, but the system becomes more complex and prone to incorrect attachment
Solution Approach 1:
The invention eliminates external identification components that require proper attachment by extracting the identification function to the battery's inherent internal resistance. This removes the reliability issue of incorrect component attachment entirely, as no external components need to be installed or positioned correctly.
Solution Approach 2:
The battery's internal resistance automatically provides identification information without requiring any external components to be attached or configured. This self-service approach eliminates attachment errors and improves reliability by using an intrinsic property that cannot be incorrectly installed.
