Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If components such as resistors or IC chips are attached to the battery for type identification, then the battery type can be determined, but additional costs are incurred and incorrect identification may occur if imitations are used
Solution Approach 1:
The invention extracts the identification function from external components (resistors, IC chips) and relocates it to the battery's inherent magnetic field characteristics. By measuring the magnetic field generated by the battery's internal structure and materials, the system identifies battery type without requiring additional attached components, thereby eliminating cost and complexity while maintaining identification accuracy.
Solution Approach 2:
The battery's own magnetic field characteristics serve as the identification marker. The magnetic field generated by the battery's internal structure, materials, and operating conditions inherently contains type-specific information. The measurement system utilizes this self-generated magnetic field signal, allowing the battery to effectively identify itself without external assistance or attached components.
2Measurement precision
If components such as resistors or IC chips are attached to the battery for type identification, then the battery type can be determined, but costs increase due to component attachment
Solution Approach 1:
The invention removes the need for expensive identification components (resistors, IC chips) by extracting and utilizing the battery's inherent magnetic field characteristics. This eliminates component procurement, attachment, and quality control costs while maintaining reliable battery type identification through non-contact magnetic field measurement.
Solution Approach 2:
The invention replaces expensive, permanent identification components with a costless, inherent magnetic field signal. The magnetic field characteristics are naturally present in the battery without requiring any additional material consumption, making the identification process economically advantageous with no recurring component costs.
