Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems lack the ability to securely grant or deny special access to physical areas while preventing manipulation attempts on the access control elements.
Innovation Solution
A blocking forwarding element, designed as an electromechanical or electronic key, incorporates a first time element and an electronic processing device to manage access decisions based on time signals and authorization conditions, thereby preventing manipulation attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control systems use traditional keys or simple electronic identifiers, then ease of operation is maintained, but security against manipulation attempts deteriorates
Solution Approach 1:
The patent changes the parameter of time verification by implementing a time element that generates time signals and compares current time with stored time values. This time-based parameter verification enhances security against manipulation attempts while maintaining ease of operation through automatic time checking in the access control process.
Solution Approach 2:
The patent introduces a time element as an intermediary component that mediates between the access control element and the control device. This time element generates time signals, determines current time, and performs time comparisons, acting as a security mediator that prevents manipulation without requiring complex user operations.
2Reliability
If access control systems implement multiple verification steps, then security is improved, but device complexity increases
Solution Approach 1:
The patent segments the access control system into distinct functional elements: an access control element, a control device, and a time element. Each segment performs a specific verification function, allowing multiple verification steps to be implemented while keeping individual component complexity low. The time element is further segmented into sub-functions: generating time signals, determining current time, and comparing time values.
Solution Approach 2:
The time element serves multiple functions within the access control system: it generates time signals for synchronization, determines current time for verification, compares time values for access decisions, and can detect manipulation attempts. This multi-functionality allows comprehensive security verification without requiring separate dedicated components for each function.
3Device complexity
If the system uses a single time element, then device complexity is reduced, but reliability against manipulation deteriorates
Solution Approach 1:
The patent changes the parameter of time verification by implementing a time element that generates time signals and compares current time with stored time values. This time-based parameter verification enhances security against manipulation attempts while maintaining ease of operation through automatic time checking in the access control process.
