Solution Overview

Problem

Existing anti-counterfeiting technologies, such as one-dimensional and two-dimensional bar codes, holograms, and RFID tags, are vulnerable to counterfeiting and raise privacy concerns, and are uneconomical for high-volume, low-unit-cost products due to high costs.

Innovation Solution

A three-dimensional authentication system using randomly oriented dual-property objects, such as bi-chromal spheres, encapsulated in a transparent material to create a unique optical signature that is difficult to replicate, which can be verified using imaging systems and databases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional anti-counterfeiting technologies (bar codes, holograms, RFID tags) are used, then authentication functionality is provided, but they are vulnerable to counterfeiting and raise privacy concerns

Engineering Contradiction:
Improveauthentication securityVSAvoidcounterfeiting vulnerability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from two-dimensional bar codes and holograms to three-dimensional objects with random spatial arrangements. The authentication tag uses multiple three-dimensional objects (spheres, cubes, or other shapes) with varying sizes, colors, and positions that create a unique signature when imaged, making counterfeiting significantly more difficult while maintaining authentication functionality

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent employs asymmetric random distribution of three-dimensional objects within the authentication tag. Each object has unique characteristics (size, color, position, orientation) that are randomly determined, creating an asymmetric pattern that is statistically unique and extremely difficult to replicate, thereby enhancing security against counterfeiting

Inventive Principle:
Principle #4Asymmetry

2Ease of operation

If RFID tags are used for authentication, then identification functionality is provided, but they incur relatively high unit costs making them uneconomical for high volume, low unit cost products

Engineering Contradiction:
Improveidentification functionalityVSAvoidunit cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent replaces expensive RFID tags with inexpensive three-dimensional objects that can be manufactured at very low cost using conventional printing and encapsulation techniques. These objects are essentially static and disposable, requiring no power source or electronic components, making them economically viable for high-volume, low-unit-cost products while providing sufficient authentication functionality

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent substitutes electronic RFID systems with a purely optical-mechanical authentication system. Instead of using electromagnetic fields and electronic circuits, the authentication is based on the physical arrangement and optical properties of three-dimensional objects that can be imaged and analyzed, dramatically reducing manufacturing costs while maintaining identification capability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If one-dimensional and two-dimensional bar codes are used, then authentication labeling is provided, but they themselves can be counterfeited (copied)

Engineering Contradiction:
Improveauthentication labelVSAvoidcounterfeiting resistance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent elevates authentication from two-dimensional bar codes that can be easily photocopied to three-dimensional objects with random spatial arrangements. The additional dimension of depth and the random positioning of multiple objects create a complex optical signature that cannot be easily replicated by simple copying, significantly improving counterfeiting resistance while maintaining authentication functionality

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

In some embodiments, an apparatus includes a tag that may include an encapsulant and a plurality of three-dimensional objects randomly oriented within the encapsulant. Each three-dimensional object may include a plurality of characteristics defining at least one statistically unique signature. At least one of the characteristics may be dependent on the orientation of the object. In some instances, the plurality of three-dimensional objects may also be randomly distributed within the encapsulant, and at least one of the characteristics defining at least one statistically unique signature may be dependent on the distribution of the objects.
