Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current password management systems, both software-based and mechanical, face challenges in ensuring secure and complex password generation and storage, particularly in the context of multiple digital devices and environments, with a risk of hacking and unauthorized access.
Innovation Solution
A portable, mechanical password generator that utilizes six mechanical assemblies to create and store complex passwords, allowing for manual setting and generation of unique passwords through a combination of wiper, drum, signal box, stamp, coding, and pendulum mechanisms, ensuring high variability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software-based password managers are used to manage passwords across multiple devices, then password management convenience is improved, but security risk increases due to hacking vulnerabilities and system errors
Solution Approach 1:
The patent replaces software-based password management with a purely mechanical system consisting of rotating drums, physical dials, and mechanical assemblies. This eliminates vulnerabilities associated with software hacking, remote access, and digital storage while maintaining the ability to generate and manage complex passwords across multiple devices through physical manipulation of the mechanical components
2Reliability
If complex password composition requirements are implemented to enhance security, then security level is improved, but ease of memorization and management deteriorates
Solution Approach 1:
The mechanical password generator automatically creates complex passwords meeting all security requirements (length, character variety, complexity) without requiring user memorization. The device itself performs the service of generating and displaying passwords, eliminating the burden on users to remember complex strings while ensuring high security standards are met
Solution Approach 2:
The mechanical device acts as an intermediary between the user and complex password requirements. Instead of users directly creating and remembering complex passwords, the mechanical system with its rotating drums and physical assemblies generates the passwords and presents them in a manageable format, mediating the conflict between security requirements and user capability
3Reliability
If regular password changes are enforced to maintain security, then security freshness is improved, but time consumption for password management increases
Solution Approach 1:
The mechanical password generator is designed for dynamic, frequent use with quick manual operation. The physical act of rotating dials and manipulating mechanical assemblies takes only seconds, enabling users to generate new passwords regularly without significant time investment, thus maintaining security freshness through frequent changes
4Volume of moving object
If portable mechanical password generator is designed with compact dimensions, then portability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The password generator is divided into separate mechanical assemblies including individual rotating drums, distinct dial mechanisms, and modular components. This segmentation allows each component to be manufactured and assembled separately, making it easier to achieve the required precision in a compact overall form factor while maintaining the complexity needed for secure password generation

AI summary
The present invention relates to a portable mechanism, constructed from a plurality of assemblies, which generates and displays complex character combinations (3) by the manual adjustment of an access code (2) by pressing the control knobs (4,5,6,7,8,9) with subsequent manipulation on the adjusting wheel (1), then by pressing the main control knob (10) and renewed rotation on the adjusting wheel (1). As a result of the rotation of the adjusting wheel (1), new character combinations (3) are continuously generated up to the end of the permutation quantity. Due to the coordination of the components of the mechanical assemblies, the same start character combination (3) is always achieved for each access code (2), and, as a result of the rotation on the adjusting wheel (1), each further visible character combination is generated as a logical sequence combination and thus mechanically stored. In addition, the generator character of the mechanism can be randomly changed by actuating the coding slides (11), so that a different start character combination (3) and new sequence combinations are generated from then on in addition to the previous access code (2). A mechanism ensures that the set character combination (3) jumps back to the original combination with the access code (2) when the adjusting wheel is released.
