Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional authentication technologies (holograms, RFID tags, microprints) are used, then authentication functionality is provided, but they have limited success in preventing counterfeiting and result in significant financial losses

Engineering Contradiction:
Improveauthentication effectivenessVSAvoidcounterfeiting success
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and utilizes naturally occurring microscopic texture patterns that are inherently present in physical objects (such as paper fibers, fabric weaves, material grain) rather than applying artificial authentication features. These extracted microscopic textures serve as unique authentication identifiers that are extremely difficult to replicate, directly addressing the counterfeiting problem by using properties that cannot be easily copied.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the parameter of authentication from macroscopic features (visible to naked eye) to microscopic features (requiring specialized imaging). By capturing and analyzing texture patterns at the microscopic level, the system creates authentication markers that are invisible to casual observation but can be verified through the specialized imaging device, thereby preventing counterfeiting.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If high-resolution microscopic texture capture is implemented, then authentication accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvetexture pattern resolutionVSAvoidlens system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a Double Gauss lens architecture that is a well-established, standardized optical design used in many applications. This universal lens type provides high-resolution imaging capabilities while benefiting from extensive existing manufacturing infrastructure and design knowledge, thereby achieving high measurement precision without proportionally increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent captures microscopic texture patterns as digital images, creating a replicable digital representation of the physical texture. This digital copy can be stored, transmitted, and compared without requiring the physical object to be present, enabling authentication through data comparison rather than physical inspection, thus reducing the complexity of handling and analyzing physical samples.

Inventive Principle:
Principle #26Copying

3Reliability

If specialized lens systems are used for microscopic texture capture, then authentication reliability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveauthentication accuracyVSAvoiduser friendliness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically captures microscopic texture images and performs authentication comparisons without requiring manual intervention for image acquisition or analysis. The device autonomously processes the authentication task, making it easy to operate while maintaining high reliability through automated image capture and pattern recognition algorithms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent pre-enrolls authentic objects by capturing and storing their microscopic texture patterns in a database before authentication is needed. This preliminary action creates a reference library of genuine textures, allowing rapid authentication by simply comparing new images against the stored patterns, thereby simplifying the operational process while maintaining high accuracy.

Inventive Principle:
Principle #10Preliminary action
