Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a resistor or IC chip is attached to the battery for identification, then the battery type can be determined, but additional costs are incurred and the risk of counterfeiting increases

Engineering Contradiction:

Improvebattery type identification accuracyVSAvoidcomponent attachment requirement

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The battery's own inductance component serves as the identification marker. By measuring the resonance characteristics of the battery itself without requiring external identification components, the system eliminates the need for attaching resistors or IC chips while maintaining accurate battery type determination

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical approach of attaching physical identification components (resistors, IC chips) with an electrical measurement approach. By measuring the electrical resonance characteristics inherent to the battery's inductance, the system substitutes physical modification with non-invasive electrical characterization

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a resistor or IC chip is attached to the battery, then identification is possible, but counterfeiting risks make correct identification impossible

Engineering Contradiction:

Improveidentification authenticityVSAvoidcounterfeiting risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The battery's inherent inductance component serves as its own unique identification marker. Since this physical property is intrinsic to the battery's design and cannot be easily replicated or counterfeited, the system achieves reliable authentication without vulnerable external components

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent measures fundamental electrical parameters (resonance frequency, impedance characteristics) that are determined by the battery's physical construction. These parameters change based on battery type but cannot be easily altered or faked, providing a reliable basis for authentic identification

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If external identification components are used, then battery type can be determined, but costs are incurred

Engineering Contradiction:

Improvebattery type determinationVSAvoidadditional components

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts and utilizes the identification function from external components and relocates it to the battery's inherent electrical characteristics. By measuring the resonance properties of the battery itself, the system removes the need for separate identification components entirely

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The battery's inductance component, originally serving only as an electrical element, is made multi-functional by also serving as the identification marker. This universal use of existing components eliminates the need for additional specialized identification parts

Inventive Principle:

Principle #6Universality (Multi-functionality)
