Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional authentication methods (cards, PINs) are used, then the system is easy to operate, but security is compromised due to theft, duplication, and unauthorized access

Engineering Contradiction:

Improveauthentication securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces mechanical authentication systems (cards, keypads, touchscreens) with a biological authentication system using EEG brainwave patterns. This substitution eliminates physical components that can be stolen, duplicated, or malfunction while providing a more secure and convenient authentication method that works for users with physical or mental disabilities

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the authentication parameter from physical objects (cards, PINs) to physiological parameters (brainwave patterns). By measuring electrical activity in the brain through EEG sensors, the system captures unique neural patterns that serve as authentication credentials, fundamentally changing how authentication is performed

Inventive Principle:

Principle #35Parameter changes

2Reliability

If conventional routing methods (keypads, touchscreens) are used, then the device is simple, but reliability deteriorates due to freezing, sticking, and user errors

Engineering Contradiction:

Improverouting accuracyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical routing interfaces (keypads, touchscreens) with a biological interface using EEG brainwave detection. This eliminates components that can freeze or stick while providing a more reliable routing method that accurately captures user intent through neural patterns

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses the user's own brainwaves to perform routing decisions, eliminating the need for external mechanical interfaces. The biological system directly translates neural activity into routing commands, reducing dependency on physical components that can fail

Inventive Principle:

Principle #25Self-service

3Reliability

If cards and PINs are used for authentication, then the system is easy to implement, but vulnerability to theft and duplication increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces physical authentication media (cards, PINs) with a digital biological authentication system using EEG patterns. This substitution eliminates the risk of physical theft and duplication while maintaining implementation feasibility through software-based neural pattern recognition

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a digital copy of the user's brainwave patterns as an authentication credential. Unlike physical cards that can be stolen or PINs that can be observed, the digital neural pattern copy provides secure authentication that cannot be easily replicated or compromised

Inventive Principle:

Principle #26Copying

AI summary

Systems and methods for authenticating and/or routing a digital signal are provided. A system may include a central database configured to store a set of signature brain wave responses as part of a profile of a user. The system may include a transaction device, a sensory device, and an EEG device. When a transaction request is received from the user, the system may be configured to present the user with a sensory prompt, detect a response of the user to the first sensory prompt, compare the response to the signature response in the profile associated with the sensory prompt, and, when the response matches the signature response within a predetermined delta, authenticate and/or route the transaction request.
