Solution Overview

Problem

Users face challenges in securely managing unique passwords for multiple systems and authenticating securely due to the vulnerability of electronic solutions to remote attacks, and existing multi-factor authentication methods are susceptible to compromise through phone number porting and electronic device hacking.

Innovation Solution

A mechanical security-code selection and recall device featuring interlocking wheels with alphabetic, numeric, and symbolic characters, allowing users to generate unique password sequences or authentication codes offline, without requiring electrical power or electronic connectivity, and supporting registration and ownership verification processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If electronic password storage systems (cloud-hosted systems, mobile applications with vaults) are used to store passwords, then password management becomes easier, but the system becomes vulnerable to remote attacks and malicious software

Engineering Contradiction:
Improvepassword managementVSAvoidsecurity against remote attacks
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces electronic/digital password storage systems with a purely mechanical device consisting of rotating wheels with characters and code symbols. This mechanical system generates passwords through physical manipulation of wheels without requiring electrical power, electronic connectivity, or software, thereby eliminating vulnerabilities to remote attacks and malicious software while maintaining ease of password generation and management

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

2Ease of operation

If reflected codes (SMS, email, voice call) are used for second-factor authentication, then authentication can be performed remotely, but the system becomes vulnerable to phone number porting and account compromise

Engineering Contradiction:
Improveremote authenticationVSAvoidsecurity against account compromise
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces electronic communication channels (SMS, email, voice calls) with a mechanical code generation device. The device uses rotating wheels with characters and symbols to generate authentication codes locally without requiring network connectivity. This eliminates dependence on vulnerable communication channels while enabling authentication through physical device possession and manual code entry

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

3Reliability

If time-synchronized code generators are used for second-factor authentication, then security is improved through code generation algorithms, but the system requires electronic devices that may be compromised remotely

Engineering Contradiction:
Improveauthentication securityVSAvoidremote compromise of electronic device
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces electronic code generation algorithms with a mechanical system using rotating wheels inscribed with characters and code symbols. The wheels are rotated to selected positions to generate authentication codes, eliminating the need for electronic processors, power sources, or network connectivity. This maintains authentication security through deterministic mechanical operations while removing the attack surface associated with electronic devices

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

4Reliability

If users create complex passwords with multiple character types to satisfy security policies, then password strength is improved, but the difficulty of remembering passwords increases

Engineering Contradiction:
Improvepassword strengthVSAvoidpassword recall
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent enables users to generate their own strong passwords on-demand using the mechanical wheel device, eliminating the need to memorize complex passwords. The wheels contain multiple character types and code symbols that can be combined to create passwords satisfying security policies. Users simply rotate the wheels to selected positions to generate each password as needed, with the device serving itself to produce secure credentials without requiring user memory or electronic storage

Inventive Principle:
Principle #25Self-service

AI summary

A device includes a viewfinder wheel with at least one viewfinder window, two or more code wheels rotatably coupled together with the viewfinder wheel about an axis, a plurality of characters, a plurality of code symbols, and a plurality of internal windows. The characters are spaced about a circumferential outer side of the viewfinder wheel and the code wheels. The code symbols are located in regions of a surface of each of the code wheels with each of the regions spaced out a different distance from the axis. The internal windows are in at least one of the code wheels adjacent the viewfinder wheel, wherein alignment of one of the characters of each of the viewfinder wheel and the code wheels at a key sequence location reveals through the viewfinder window and one or more of the internal windows a code sequence comprising a subset of the code symbols.
